Dongfeng Tianlong Renault engine has a knocking cylinder and white smoke

1. This is generally caused by the slippage of the belt; there will also be engine operation.The sharp sound of dry friction of metal parts is generally the cause of damage to the bearings of generators, pumps and steering boosters; if it is the sound of engine running air leakage, it may be the result of blockage of the exhaust system, leakage or breakage of the vacuum tube.

2. Abnormal noise only exists during idle or low-speed operation. The reasons for the sound are: the gap between the piston and the cylinder wall is too large; the piston pin assembly is too tight or the connecting rod bearing assembly is too tight; the gap between the straight rod and its guide hole is too large; the contour of the gas distribution cam is worn; sometimes, the starting grip is loose and the pulley makes the pulley to sound (obvious when the speed changes).

3. Knocking the cylinder is the abbreviation of the phenomenon of the piston knocking on the cylinder wall. This kind of failure is a malignant failure of the engine, which mostly occurs when Chaiwei's engine is seriously worn or the engine is not repaired at the beginning of the overhaul. The phenomenon of cylinder explosion failureWhen a knocking cylinder failure occurs, the main feature is that the cylinder emits a crisp and rhythmic metal knocking sound, which changes with the change of temperature.

4. The temperature is not enough. Due to the insufficient temperature of the engine, the mixture of fuel and air sprayed into the cylinder cannot be 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.

5. Abnormal sound of Dongfeng Tianlong Renault engine: the wear of the piston, the knocking sound caused by the excessive gap between the piston and the cylinder wall. The sound of the engine bursting and knocking on steel. It may be a valve failure. Please take care of your car.

Dongfeng Tianlong Renault 375 lacks power, what's wrong with the throttle sinking, no black smoke

1. Analysis of the problem: This problem is usually caused by insufficient rigidity of the body, resulting in deformation of the vehicle while driving, friction or shaking of the door and the frame, or dewelding in some places resulting in steel Friction between boards, etc.

2. Inlet pressure, intake temperature, water temperature, oil pressure, power supply virtual connection, oil rail pressure, measurement unit, low-pressure oil line, filter element blocking high-pressure oil line, will all cause insufficient power. For specific situations, the data stream should be read with a diagnostic instrument.

3. Symptoms: the engine is weak, the speed decreases, black smoke is coming out, there is a knocking sound in individual cylinders, the engine is not stable, the vibration is loud, the engine is overheated, etc. Due to different reasons, the performance is not exactly the same.Cause Analysis 1 Insufficient oil supply.

4. Relatively speaking, the power of Dongfeng Tianlong with Dongfeng Cummins is slightly inferior. Now Dongfeng Tianlong with Renault DCI engine is powerful and fuel-efficient. Looking for Dongfeng Tianlong accessories, SAIC Parts Network.

5. Replacement cycle and replacement method of antifreeze. Different manufacturers will have different recommended replacement cycles for the original antifreeze, but most manufacturers recommend that car owners replace the vehicle antifreeze every 2 years, and some manufacturers also show that their original antifreeze replacement cycle is 4 or 5 years.

How is the engine quality of Dongfeng Renault?
