The Shangchai 6114 engine has black smoke, no power, and the idling vibration is large

The engine is seriously carbonized. The most common reason for car shaking is that the throttle valve is too dirty or the fuel injector has too much carbon.

Poor diesel atomization: the pressure adjustment of the fuel injector is too low, and the pressure regulator spring of the fuel injector is broken or stuck. The injector needle valve and valve seat are carbonised, and the needle valve is stuck or worn too much. The pressure reducing ring of the pump valve of Cummins is too worn, causing the injector to drip oil.

If the jitter in the idle state does not decrease due to the operation of the on-board air conditioner compressor, this jitter is likely to be caused by the aging of the engine foot, and the new foot needs to be replaced in time. Uneven tire weight is also one of the causes of shaking.

There is carbon accumulation in the combustion chamber, causing the gas ring of the piston ring to be stuck and poorly sealed. Oil sludge is produced in the lubrication system, which blocks the return hole of the oil ring and weakens the oil scraping performance. There is wear between the piston and the cylinder wall. The valve seal is corrosion-aging and the sealing performance is invalid.

How many liters of oil should be added to the Shangchai 6114 engine?

1. Normally, CF level is used, such as the Great Wall Dragon King and Kunlun Tianhong. The brand doesn't matter. As long as it is genuine enough, the oil can be added.The diesel engine model S19S1100 is generally about 2 liters; the model 1125 is about 8 liters.

2. Depending on the car model, the amount of oil required is also different. Generally, three to four liters for small cars, and 4 to 5 liters for medium-sized cars. The general principle is that as long as it is added and does not overflow.

3. The amount of oil refueling the 6-cylinder engine oil for you is related to factors such as engine displacement, usage environment and usage habits, so it needs to be calculated according to the specific situation. Generally speaking, the oil capacity of a 6-cylinder engine is between 5-8 liters. For specific capacity, you can check the vehicle's instruction manual or consult a professional technician.

4. It depends on the diesel engine model, S195, S1100, generally about 2 liters, and 1125 is about 8 liters.Generally speaking, when adding oil, the oil should not exceed the upper scale of the oil ruler, and when using a diesel engine, the amount of oil should not be lower than the lower scale of the oil ruler.

5. Generally, small cars add three to four liters, and medium-sized cars add four to five liters. The choice of engine oil should be selected according to the requirements of the engine. There is no need to use too high-grade engine oil on engines with low requirements, nor to use lower-grade oil on engines with high requirements.

6. The diesel engine model S19S1100 is generally about 2 liters; the model 1125 is about 8 liters. The advantages of diesel engines are large torque and good economic performance. The working process of diesel engines has many similarities with that of gasoline engines. Each working cycle also goes through four strokes of air intake, compression, work and exhaust.

Shangchai 6114 engine is difficult to start

1. There are several reasons why the diesel engine is difficult to start: the diesel itself is not qualified and the wax content is high; the fuel injection atomization is not good; the fuel injection timing is not good; the airtightness is not good (piston ring, cylinder block grinding Damage or poor valve sealing), etc.

2. Fault performance: unable to start or difficult to start several times. Stop quickly after barely starting.

3. The temperature is insufficient. Due to the insufficient temperature of the engine, the mixture of fuel and air sprayed into the cylinder cannot be partially burned, and the exhaust pipe has white smoke. Therefore, after the locomotive starts, you should pay attention to the insulation of the water tank and use the middle throttle to operate, so that when the temperature of the locomotive reaches more than 50 degrees, the load should be gradually increased.

4. Fault phenomenon: turn on the ignition switch, turn the ignition switch to the starting position, and the engine does not start.

5. The oil road knot, or add negative 20 oil, and heat the oil-water separator may be fine. If it doesn't work, you can also call. Hey hey.. I'm on firewood.

What is the fault of the air inlet when the Shangchai d6114 engine is idling?

Reason: The intake valve leaks or the valve gap is too small, causing the valve to close loosely after thermal expansion. The gap between the exhaust valves is too large, resulting in insufficient opening or completely inability to open the valve. There may be no air filter installed, or the air filter model is wrong.

The engine has serious carbon accumulation. The most common cause of idling jitter is excessive carbonisation of the throttle valve or fuel nozzle.

It may be leakage of the intake pipe or various valves. When the engine intake is not right, the mixed gas will be too thick or too thin, causing the engine to burn abnormally, and the engine idling and shaking with sound.

How many large models are there for the Shangchai D6114 engine?

1. There are two types of D6114, type A and type B. The Type A machine is almost completely equivalent to Cummins' 3C. The Type B machine has replaced the Type A machine after AVL consulting and design. Now the Type A machine has been discontinued and all the Type B machines are produced.

2. The cylinder pad of type A is made of asbestos, and the cylinder pad of type B is made of metal. The ZQ and ZLQ cylinder liners of type A are made of a water-blocking coil (and the water-blocking coil is flat), and the B-type cylinder is made of 3 channels.

3. Shangchai 114 series has D6114, D9, D4114, SC8DK, SC9DK, SC9DF. The first three are national second models, and the latter three are national third models. D6114 cylinder diameter 114 stroke 135 displacement 3 liters, D9 cylinder diameter 114 stroke 144 displacement 8 liters.

How big is the valve adjustment of the Shangchai 6114 engine

When the Shangchai D6114 diesel engine is heated, the gap between the intake valve is about 0.45 cm; the gap of the exhaust valve is about 0.35 cm.

Shangchai 6114 valve clearance, which depends on the working conditions of the engine, and the gap of the inlet row is different. The valve clearance of Xinshangchai 6114 is: the intake gap is 0.05-0.08 and the exhaust gap is 0.08-0.12MM. I hope it will be helpful to you.

Compress the dead point of the positive cylinder and adjust the gap of the valve in the relaxed state; adjust the gap of other valves after turning 360 degrees.

Let's talk about the simplest and easiest way to understand: move the car according to the steering wheel of the car, and adjust the cylinder when the cylinder of the oil pump comes out.
