Normal Starting Procedure of Shangchai SC27G Diesel Engine

4.5.1 Normal starting procedure

The G series V type diesel engine can be started smoothly at temperature of -5°C and above. Starting procedure is as follows:

Disengage the diesel enginefrom the drive system. .
Put the mechanical operating devices into the ‘running’ position.
Push the governor controlling handle to unloaded position with speed at about 900 r/min.
Insert electric key and turn the switch from the OFF position to the START position to start the engine.if it cannot be started up in 10 seconds, turn the switch from the START position to the OFF position. Make another starting after 2 minutes. If the engine cannot be started up for three times, stop starting and refer to Section 6 for troubleshooting guideline to find cause. Each starting lasts 2 to 3 seconds.

Caution: The engine should be started without load.

After the engine has started up, the switch key goes back to the ON operation from the START position automatically. The oil pressure gauge should show reading within 15 seconds after the engine has started up; otherwise, stop the engine immediately to prevent damage to the engine and find the causes and remove the fault(s) according to Section 6 Troubleshooting Guidelines.
Having started up from a hot state, the engine should run at idle for l-3 minutes before being accelerated and loaded gradually. .
Having started up from a cold state, the engine should run at idle for 3-5 minutes. Increase engine speed slowly to 1,500 r/min and run the engine with partial load. Do not run the engine with full load until the outlet coolant temperature is higher than 75°C, oil temperature 50°C and oil pressure 0.40 MPa.

Caution: Especially starting the engine from a cold stat, increase the engine speed slowly as far as possible to have every bearing adequately lubricated and oil pressure stable.

Check the instruments during the engine running at idle to see whether they work normally.

Caution: Do not accelerate and load the engine immediately after it has been started up.

Caution: Do not idle the engine for a long period of time or it can cause problems to the engine. When an engine idles, the temperature in combustion chamber is low and combustion is not complete. It can cause carbon deposit in cylinder resulting in block of the orifices of fuel injector, as well as seizures of piston rings and valves, thus leading to engine performance deterioration.

Caution: If the engine is start by a jumper cable, parallel connection of the cable should be adopted by connecting the positive pole to the positive terminal and the negative pole to the negative terminal. If the engine is start by external power supply, the circuit breaker should be set to the OFF position. Take out the key to prevent accidental activation before connecting a jumper cable.

4.5.2 Cold Start

Cold start refers to starting the engine at temperature -50°C. Choose proper cold starting aid to warm the engine according to ambient temperature and then follow the normal starting procedures to start the engine. There are, in general, several ways to warm the engine:

Warming the engine oil and coolant to 40-50°C;
Installing a heating device in the air inlet pipe or heating air by fire at the entrance of the air inlet pipe, with which special precaution must be paid for safety;
Increasing the surrounding temperature of the engine room;
Using diesel fuel, engine oil and coolant that are suitable for cold areas;
Warming battery or using battery of larger capacity or having higher discharge rate (special battery for low temperature).

4.5.3 Staring after a longtime stop or replacement of lubricating oil

If the engine hasn’t been used for less than 30 days or its engine oil has just been replaced, it is necessary to fill the lubricating system with oil. Crank the engine and make oil enter moving parts. Start the engine only after you feel light when cranking the engine. Finish the following preparation before starting the engine according to the procedures of normal starting or cold starting:

Check the oil level for being within the dipstick marks range.
Check the voltage of the battery for abnormality.
Prime the fuel system. Refer to Section 5.3 for operation.
In order to have a quick starting of a standby engine for emergency need, start the engine every three to five days and operate it until its engine oil and coolant temperatures reach 60’C and above.

4.6 Engine Operation

Cautions for operation of the engine:

Pay frequent attention to oil pressure and coolant temperature. In case of any abnormality, stop the engine immediately for inspection.

Lubricating oil pressure:

150 kPa @ idle speed (minimum allowable)

300 kPa @ rated speed (minimum allowable)

500 kPa @ rated speed (maximum allowable)

Coolant temperature:

75-95°C (normal working range)

When engine overheating starts to happen that is indicated by the coolant temperature alarming, reduce engine speed or load or take the both actions until the coolant temperature falls down into the normal range; otherwise, find the cause and remove the fault as per Section 6 Troubleshooting Guidelines.
During the operation, especially sudden decrease of load, attention should be paid to avoid the failure of the governor, which can cause sudden increase of engine speed exceeding the defined value (usually called flying away).

Once such case happens, make an emergency stop first and then check for the cause.

Caution: Over-speed running will cause serious damage to the engine.

There are significant signs before most engine faults occur, such as changes in performance, sound, or engine appearance. Listening and observing will help detect in advance or predict some problems of the engine that will occur later, with which the proper measures can be taken in time to eliminate such problems as can lead to a serious engine failure.

Typical engine fault signs:

Engine misrires

Engine vibrates abnormally

Engine sounds abnormal

Engine coolant temperature and oil pressure change abruptly

Engine produces black smoke

Engine power output is insufficient

Engine oil consumption is too much

Fuel consumption is too much

There is leakage of oil, fuel or/and coolant

4.7 Engine Shutdown

4.7.1 Normal shutdown

If the engine has just worked at a high speed and heavy load for a long time, reduce its load and speed gradually and run it at idle for 5 minutes before stopping it to let the engine cool down evenly and turbocharger speed fall considerably so as to protect the engine and turbocharger. Turn off the fuel tank cock after the engine has stopped.

If the engine will not be used for a period of time (6 months at most), keep it properly. Refer to Section 7 for engine storage.

4.7.2 Emergency shutdown

Under emergency or special condition, make an emergency stop to avoid serious engine failure. Manually pulling of the emergency stop handle can achieve an emergency shutdown.

Shangchai W Series Engine Troubleshooting Guidelines V

The agreement includes a technology transfer fee of $1.5 million, which is payable upon achievement of certain milestones, and a royalty of $2.25 per liter of diesel particulate filters (“DPF”), which could generate $2.25 million in royalty revenue in 2018 and $4.5 million in royalty revenue in 2019 if the joint venture company achieves Kailong’s projections. Kailong believes the market potential for high quality emission control systems is significant in China and together with LiqTech could scale to a capacity of 2 million liters in Silicon Carbide DPF to serve the Chinese and international market. The New China 6 standard for diesel vehicle emissions will likely put China on the forefront of emission standards in the world creating the need for better DPF in China.

LiqTech will own 30% of the company and invest $4 million in the joint venture company over a 2-year period. Kailong will invest a minimum of $2.5 million in LiqTech, conditional to Chinese government approval. In the event that government approval is not obtained, the letter of intent will terminate. In addition, the letter of intent is conditional on execution of definitive agreements.

Zang Zhicheng, Chairman of Kailong, stated, “In the past 15 years, Kailong has established a strong business platform in China for Selective Catalytic Reduction (“SCR”) Systems for the diesel vehicle industry. We have been planning to enter into Silicon Carbide (“SIC”) production and have had serious discussions with companies in Italy, Japan and South Korea. We have ultimately chosen LiqTech as our partner because of its leadership in SIC technology and its extensive knowledge in working with SIC. We believe that not only for the near term opportunity, but also for the future development of industry leading technology, LiqTech is the right partner. Kailong and LiqTech intend to work closely in sharing Kailong’s experience in China and LiqTech’s experience in SIC in developing the DPF market in China.”

Know about Basic Working Principle of Diesel Engine Fuel Filter

The fuel filter of diesel engine can filter out the harmful impurities and moisture in the fuel system, protect the normal work of the engine, reduce wear and tear, avoid clogging and improve diesel engine life. Here, we are willing to share the basic working principle of diesel engine fuel filter.

The air filter setup on most diesel engines is the same as on gasoline-powered vehicles, with the filter located inside the cold air collector box located under the hood. Most diesels have two fuel filters: a “primary” filter located between the fuel tank and the engine, which cleans the fuel before it gets to the fuel transfer pump; and a “secondary” filter up near the engine, which gives the fuel a final cleaning before it gets to the fuel injectors.

Basic Working Principle of Diesel Fuel Filter

The purpose of any diesel fuel filter is to remove foreign particles as well as water. The use of a suitable filtration system on diesel engines is a must to avoid damage to closely fitted injection pump and injector components. Filter’s ability varies between the type and manufacturer. On diesel engines primary and secondary filters are used. The primary filter is capable of removing dirt particles down to 30 microns and the secondary filter between 10 to 12 microns. Secondary filters are available between 3 and 5 microns, which are used in severe service operations. The primary filter is usually located between the tank and the supply pump, the FWS is one type of the primary filters. The secondary filter between the supply pump and the injection pump.

Diesel fuel filter is referred to as full-flow filter, because all the fuel must pass through it before reaching the injection pump. Some filters use internal replaceable element inside a bowl or shell. These are commonly referred to as a shell and element design. Most fuel filters used today are of the spin-on type, which allow for faster change out since the complete filter is a throwaway.

Besides, if the filter is installed on the pressure side of the boost pump it must have sufficient strength to handle pump pressure without bursting or leaking. The filter must be located well away from sources of heat, preferably outside of the engine compartment.

The fuel filter of diesel engine is mainly composed of three parts: filter element, the shell and filter base (As shown in Figure 1). All models are universal except for the overflow valve 8 that has two structures. Choosing C0810A or C0810B filter should be on the basis of different models. For the 12 cylinder V type diesel genset, it should be installed in parallel with each one of C0810A and C0810B.

The fuel is sent to the fuel filter mainly by the fuel pump. The impurities in the fuel will be cleared through the paper filter element. And then the fuel can enter the inner cavity of the filter cylinder. Through the collection chamber of the filter sea, it leads to the fuel injection pump. The filter holder is equipped with fuel return fitting and the overflow valve is also installed inside. When the fuel pressure in the fuel filter is more than 78kPa(0.8kgf/C㎡), the excess fuel will return back to the fuel tank from the fuel return fitting. When connecting the low pressure fuel line, you should connect it according to the arrow pointing direction on the socket to avoid connection error. The filter seat and the shell are connected by pull rod, and it is sealed by rubber ring. Due to there is a bleeder plug on the top of filter seat, users can release the screw to clear the air of the fuel filter in use.

The fuel filter of the diesel engine is fixed on the engine body and bracket with two M8-6H screws. If users find that the fuel supply is not smooth, it is possible that the filter element is pluged. At the moment, you should dump the fuel oil. You can directly loosen the pull rod nut of diesel generator set, remove the shell, and take out the filter cartridge (As shown in Figure 2). After the filter element is dipped into gasoline or diesel oil, you can gently wash the dirt off with brush (As shown in Figure 3). If the filter cartridge is broken or hard to clean, it must be renewed. Then install it as shown in Figure 1 and inject the clean fuel.

Simple Ways to Deal with Diesel Generator Failure

Most of time, diesel generator runs abnormally because of battery long time no maintenance or the deviation between components . In reality, it can be back to normal as long as you make a little adjustment. Therefore, we should have the ability to deal with the faults.

Generators are crucial for providing an ‘insurance policy’ in case of power failures and offer some peace of mind. But the last thing anyone wants is for a generator to fail as well! That’s why it is so important for generators to undergo regular maintenance to ensure all their systems are in good repair and functioning properly.

Here are some of the top 10 reasons that generators fail—and some tips for what you can do to address the risk in the meantime.

Problems with the Battery System

Based on our experience, close to half of all emergency generator failures are caused by problems with the battery. Routine battery maintenance is important for good performance. Connections need to be cleaned and tightened. You should also note the service life of your batteries and replace them proactively. Towards the end of its life, a battery will provide closer to 80% of its designated capacity. Periodically checking the circuit breaker on the battery charger is also recommended, as this is a frequent cause of battery failures.

Controls Not Set for Automatic Operation

Although it may seem obvious, one issue that we see frequently is the master controls for the generator not being set for “Auto” (automatic operation). This can also occur when the emergency stop button is pressed. Building the habit of double-checking the master control set is a great way to prevent failures.

Overheating from Cooling System Failures

Cooling systems failures are most commonly caused by worn-out hoses and drive belts. Both should be regularly inspected to ensure they are working properly and set at the correct tension. Another component that needs inspection is the radiator core. Radiator cores can become plugged, either from dust and debris or as a result of corrosion and dirty coolant. Monitor the coolant to assure cleanliness and correct chemical balance, then perform a visual check to ensure plugging does not cause overheating.

Water Contamination or Lack of Fuel

Don’t let water get into your fuel supply! Water or moisture in fuel can easily damage diesel engines or impact their overall performance. Keep your fuel tanks topped up and use fuel stabilizers to protect the diesel from water contamination.Take a fuel sample regularly and inspect for discoloration or abnormal smell. Remember to monitor the fuel levels consistently as well. It’s another obvious tip, but being proactive about topping off your tanks will ensure you do not find yourself in a panicked situation as your generator is about to shut down!

Switchgear Problems

Switchgear or automatic transfer switches (ATS’s) contain moving parts that need to be inspected during maintenance. Issues with switchgear are commonly the result of some kind of mechanical failure. Parts can seize if they are left in one position for too long, so monthly testing is recommended. Check for loose connections or a buildup of dirt, dust and other debris. This will help ensure everything is working smoothly.

For the failure of diesel generator, first you should have a adjustment and check whether it is helpful. Then what problems should we pay attention to when making a adjustment?

Regulator adjustment: If the faults like charging ammeter pointer stops movement, charging ammeter is too large or small occur during the process of using diesel generator, it needs a regulator to adjust. If battery charging current is too large, it will shorten the service life. If it is too small, it can’t give battery charged on time. If the charging ammeter shows the charging current is too large when diesel generator works, you should adjust the current limiting spring of regulator to shorten the spring. The current should be reduced. Or vice versa. In the process of adjusting, not too hard, light touching until it meets the requirements.

Oil pressure adjustment: In general, diesel generator has two lubrication methods. One is pressure lubrication, the other is splash lubrication. Diesel generator lubrication quality is closely connected with oil pressure. Therefore, when the diesel generator is at work, the oil pressure must be controlled within the valid range.

Diesel generator decompression adjustment: In the process of using diesel generator in winter, it is hard to start because of the cold weather or battery shortage. To make the diesel generator set gets started, you can depend on the diesel generator inlet valve decompression way to reduce the compression radio and improve the starting resistance.

Fan belt adjustment: The tightness of the diesel generator fan belt should be just right. If the belt is too tight, it will exacerbate the wear to the direct generator bearings, water pump bearings and fan bearings. If it is too loose, it will cause insufficient fan air volume, influence the cooling effect of the cooling water, reduce the water pump flow, which can’t reach the usage requirement. So the fan belt should be regulated according to the usage requirements.

The above processing methods to deal with generator failures are shared by Jiangsu Starlight Electricity Equipments Co.,Ltd, a professional manufacturer of diesel generator. Hope it can help you.

Power failures can happen for a number of reasons: bad weather, an overloaded power station, or damage to transmission lines. Whatever the reason, many businesses and government organizations put backup generators in place to ensure normal operation can continue while the issue is resolved. Depending on the situation, loss of power can be incredibly detrimental to service delivery or productivity.

Reasons for Diesel Engine Cylinder Liner Wear

Diesel engine cylinder liner should keep air intake system clean in the process of using. Avoid working without installing air filter. In addition, avoid overloading operation, maintain a good cooling condition and check the diesel engine cylinder liner periodically. However, any equipment used for a long time will wear. What are the reasons for diesel engine cylinder liner wear? The main reasons are as follows:

First. Incorrect oil brand

This will result in a poor lubrication and lead to a serious wear of cylinder liner.

Second. Use inferior diesel

Severe coking after combustion, which will lead to a serious wear of cylinder liner.

Third. Filter failure

Especially air filter fracture, the air come into the cylinder without passing filter short circuit. Due to the dust in the air, impurities enter the cylinder, which is easy to lead to a serious wear of diesel engine.

Fourth. Quality and assembly problems of diesel cylinder liner.

Fifth. Operational problems

Cold-starting, especially cold-starting in winter, due to the oil viscosity and poor mobility, it will lead to insufficient oil supply provided by oil pump. Meanwhile, the oil of diesel genset on the cylinder wall flow down after parking. Thus, it won’t be so lubricated as usual at the moment of starting. There is no doubt that it will increase wear of cylinder liner.

Last but not least, driving at low temperature.

It can’t maintain a good lubrication due to the low temperature so as to increase wear of cylinder liner.
