How to return the engine shaking and no oil when the Rongwei 750 is replaced after replacing the steel cushion cool car

The engine carbon has been cleaned, the throttle valve has been cleaned, and the oil pad has also been replaced. If you still find that the body shakes after all these, it is recommended that you go to the maintenance The repair shop checks whether the fuel supply pressure and the intake pressure sensor are normal. If the oil supply pressure of the oil pump is abnormal, the numerical error and improper operation of the intake pressure sensor will cause the body to shake.

The quality of the oil is poor. When there are too many impurities or too much moisture in the fuel, it will naturally lead to insufficient power, and poor-quality fuel can easily lead to the blockage of oil pump filters, gasoline filters, fuel injectors and other components with small holes or filtering functions, resulting in poor oil supply and engine function decline.

Replacing the cylinder pad of Rongwei 750 is a relatively complex maintenance task. You need to pay attention to the following points: confirm whether the cylinder pad needs to be replaced. If the water temperature in the engine is too high, there is gasoline or water in the water tank, and the oil becomes cloudy, it is likely that there is a problem with the cylinder cushion.

What should be changed was the accelerator pedal, but the one that should not be changed was all replaced, and no one mentioned what should be changed. This may be the current situation of the auto repair industry; the car owner thinks he has been deceived, and the repairman says that I am serious, which makes the two sides more and more distrustful.

Hello, if the spark plug cylinder line and ignition coil are all checked, how about measuring the steel pressure with the instrument? Measure all 4 steel pressures and compare them. If there is an obvious difference, it is caused by the damage of the cylinder pad. [ If there is a problem with the car, ask the car master.4S store professional technician, 10 minutes to solve.

It should be tightened according to the required torque. Too much loosening will cause air leakage. Too tightening will make the gasket lose its elasticity, which will also cause air leakage. Because the conical seat spark plug does not use a sealing pad, it is especially important to observe the tightening torque.

What's wrong with the Rongwei 750 engine fault light on

The fault light is likely to be due to oil problems; if the fault light continues to be on and the vehicle has obvious abnormalities in use, you should go to the 4s store immediately. On-site maintenance; For your car, it is recommended that you change the gas station first and then drive at high speed. If the fault light will turn on after driving at high speed, it is recommended that you go to the 4s store in time to get the fault code.

Rongwei 750 accelerates speed to exceedThe failure light of more than 3,000 may be due to the following reasons: Engine system failure: It may be caused by the failure of the engine control unit. The specific cause of the failure can be determined by checking the fault code, such as ignition system failure, fuel system failure, etc.

It is recommended to go to the repair shop for computer testing and pay attention to the safety of the car. I hope my answer can help you [If there is a problem with the car, ask the car master. 4S store professional technician, 10 minutes to solve.

If it is not for the constant serious shaking, the ignition coil can basically be ruled out. The age of the vehicle is too large and the mechanical aging causes the engine to be in poor working condition, resulting in poor combustion and ignition, resulting in the alarm light on. The failure of some sensor computer boards itself causes the alarm light to turn on. There are many reasons why the alarm light is on, but the first three are the most common.

The quality of the oil is poor. When there are too many impurities or too much moisture in the fuel, it will naturally lead to insufficient power, and the poor-quality fuel can easily lead to the blockage of the oil pump filter, gasoline filter, fuel injector and other parts with small holes or filtering functions, resulting in poor oil supply and decreased engine function.

What is the compression ratio of Rongwei 750

1. For example, No. 90 gasoline can ensure that it does not produce explosion when used in engines with a compression ratio of less than 9, and No. 97 gasoline can ensure that the compression ratio is not greater than 7 There will be no explosion when used in the engine.

2. Hello, I'm a Rongwei MG car purchase consultant. Rongwei 750 has extraordinary atmosphere, stable power, good acceleration and control performance.The high-performance engine is powerful, faster, and the speed of the car responds more directly to the accelerator underfoot. There is no small problem with quality, but its fuel consumption will be higher.

3. The key indicators of Rongwei 7508T are all higher than those of the Accord 4L, but the price is about 30,000-50,000 yuan cheaper than the 4L Accord, which is very cost-effective.

4. If the compression ratio in the cylinder is more than 10, it is better to add 97# oil, otherwise the engine will explode and damage the life of the machine.

How about the Rongwei 750 engine?

The Rongwei 750 8T engine adopts ultra-high-pressure and medium-cooled turbocharging technology, which is equivalent to the displacement of 3L of natural intake. Like the 8th generation Accord 4L i-VTEC technology, it is the most advanced engine technology in the same class.
