Hongqi V6 engine has oil and fire, why can t it be hit

1. Whether the steering wheel is in a deadbolt state. The solution is simple, as long as you hit the steering wheel hard and twist the key at the same time, you can generally unlock the steering wheel lock quickly, and the ignition is an instantaneous thing.

2. Did you not return the gear to P gear when you parked? Think about it, if the D or R gear can be ignited, the jump of the vehicle at the moment of ignition is undoubtedly a huge safety hazard. Therefore, for automatic transmission vehicles (AT, CVT, AMT), manufacturers will preset this mode, and repeatedly inform in the manual:

Make sure the gear is in the P position when ignition.

3. One-button start sometimes encounters the trouble of power loss of the smart key, obviously the key is in the car, but the instrument always shows 'key matching error', this situation is likely to be the power loss of the smart key, and the start system can not sense the weak radio waves emitted by the key. Therefore, it is recommended to pick up the smart key and put it on the start button, and then press the button to start.

4. Check whether the battery has electricity. If the ignition is not ignited, it may be due to the loss of power or the expiration of the battery life due to the long-term headlights have not been turned off, and the battery is generally replaced in time according to the maintenance manual.

5. See if there is oil. If the fuel gauge shows that it is below the red line, it will not ignite. At the same time, pay attention to the quality of the oil. There have been car owners who found that there was water and mud in the fuel tank after disassembling the car, and with such oil, it is impossible for the car not to break.

6. No antifreeze is added.

Some car owners add water or inferior antifreeze to the car, resulting in a particularly cold winter, causing the entire waterway to be frozen, the engine to be frozen and cracked, resulting in the car water pump can not operate, can not catch fire, and injure other parts of the engine.

Hello, this one to see if the fire coil and starter are faulty, and then check the spark plug.

Ma Zhiyuan's "Tianjing Shaqiu Thoughts" The sun is setting, and the heartbroken person is at the end of the world.

Check the steam nozzle, fuel distribution valve, and throttle valve.

There are strict standards for engine overhaul, and the following is an important "indicator" for engine overhaul, and the engine is going to be overhauled on the surface of these signs.

1.Cylinder pressure difference: The cylinder compression pressure should meet the original design regulations, check that the tachometer and cylinder pressure gauge do not meet the requirements and are unqualified, and the pressure difference between each cylinder is unqualified

The difference between the pressure of each cylinder and the average pressure of each cylinder is not more than 8 measured with a tachometer, cylinder pressure gauge or with an engine comprehensive analyzer (the pressure difference between each cylinder of Yuedong engine that does not meet the standard is unqualified.) When the cylinder pressure of the Yuedong engine is lower than its standard value, there will be serious black smoke.

2.Large fluctuation of idle speed: the engine is stable at idle speed, and its speed meets the original design regulations. The speed fluctuation is not more than 50r min, and the operation test is carried out with the tachometer or measured with the engine comprehensive analyzer.

3.Low power: the maximum power of the engine shall not be lower than 90 of the original design calibration value, and the dynamometer shall be measured according to the relevant regulations.

4.Fuel consumption rate: The minimum fuel consumption rate of the engine shall not be higher than the fuel consumption meter required by the original design.

5.Low torque: the maximum torque of the engine shall not be lower than 90 of the original design calibration value.
