When the car burns gas, the engine shakes badly, and the burning oil returns to normal 30

The shaking of the car after the oil to gas is actually the unstable idle speed of the engine, which can be checked one by one from the following aspects:

Idle Control System Check:

1. Check whether the idle control valve is working properly.

2. Use the decoder to observe whether the throttle position signal is normal.

Gas System Inspection:

1. Use a decoder to check whether the mixture is too thin or too thick.

2. Use the decoder to check whether the pulse width of the fuel injection is normal.

The common problem of many cars, some cars are not suitable for gas change, which is related to the ECU of the car, that is, the electronic control unit of the car, many parameters have changed after the gas change, the electronic control unit is not suitable and outputs the wrong instructions, this to brush the ECU may be good, but it is not guaranteed, many cars brush the ECU, the overall performance is not as good as before, so I personally do not recommend changing the gas, not saving much money.

After the car has been changed, have you gone to the 4S shop to use the computer to detect your gas value, it must be between, and then the gas pedal to idle speed 3,000 rpm, the value can not be greater than, the value jumps 8 times in 10 seconds. The air volume must be adjusted to prevent the uneven air intake, which will cause the engine valve to burn out. Based on what you've provided, your gas value is definitely wrong right now and must be checked immediately.

If the engine still shakes in the future, the valve of your car will definitely burn out, and you will have to pay for it!

The gas mixing ratio is not right, it should be that the mixer is a little thin, and it should be better to adjust it, and the oil-to-gas car is a little shaky, and it is not very stable.

This may be because there are a series of problems with the quality of the fuel added by the car, the moisture content is large, resulting in the lack of the best power delivery, or it may be that there is an aging line inside the oil pump, the gasoline filter element is seriously blocked, and there are some faults in the car parts, which requires a comprehensive overhaul of the car at this time.

If this situation occurs just after refueling, it is likely that the oxygen sensor of the car engine has organic oil, which causes the car to idle unstable; In this case, you should go to the inspection in time, and you can choose to go to the 4S shop or the repair shop to carry out the maintenance inspection.

It may be caused by excessive carbon deposition in the engine, which will occur when the engine is not completely burned or the oil cannot be completely combusted, and the carbon deposition must be dealt with at this time, which will be converted into a gaseous state under the action of high temperature.

The shaking of the car after the oil to gas is actually the unstable idle speed of the engine, which can be checked one by one from the following aspects:

Idle Control System Check:

1. Check whether the idle control valve is working properly.

2. Use the decoder to observe whether the throttle position signal is normal.

Gas System Inspection:

Summary. First of all, your first question is the common problem of many cars, some cars are not suitable for gas change, which is related to the ECU of the car, that is, the electronic control unit of the car, many parameters have changed after the gas change, the electronic control unit is not suitable and outputs the wrong instructions, this to brush the ECU may be good, but it is not guaranteed that many cars brush the ECU, the overall performance is not as good as before, so I personally do not recommend changing the gas, not saving much money.

When the car burns gas, the engine shakes badly, and the oil burns back to normal.

First of all, your first question is the common problem of many cars, some cars are not suitable for virtual flush gas change, which is related to the ECU of the car, that is, the electronic control unit of the car, many parameters have changed after the gas change, the electronic control unit is not suitable and the key is out of the wrong instruction, this to brush the ECU may be good, but it is not guaranteed, many cars brush the ECU, the overall performance is not as good as before, so I personally do not recommend changing the gas, and the reputation of the manuscript is not much money.

He's a taxi remodel.

Good. What is the general situation of this Burning gasoline is completely normal.

Hello, it means that the ignition coil and spark plug are fine, and the problem is in the gas system. Assuming that the 3 cylinders are missing, turn off the fire first, pull out the nozzle of the nozzle 3 of the spray rail, ignite the jujube to disturb the Zen, switch to burning gas, and touch the No. 3 nozzle with your fingers to see if there is any air spray (ps: this link must be fireproof, the ignition point of natural gas is very high, as long as there is no open flame, there is no problem).

If there is air ejection, the problem should be at the connection between the air pipe and the engine to see if the gas is not entering the cylinder. If the No. 3 nozzle is out of gas, then choose another nozzle (such as No. 2) to pull it out to see if there is gas, if not, it means that the gas system as a whole has no gas supply (in fact, there should not be a situation where No. 2 is not available, because only 3 cylinders lack cylinder bench dust and others are not lacking, indicating that only 3 nozzles are gasless). Next, each nozzle has a separate power supply line, the power supply line of No. 2 and No. 3 nozzle is exchanged, and at the same time, the air pipe of No. 2 and No. 3 nozzle is unplugged, and then the ignition is changed to the air port.

The lack of cylinders in gas vehicles is generally a problem. Either the spout, or the power line, or the spout air pipe is leaking.

Points, don't smoke, okay.

Have a great day.

If you are satisfied with this service, please give a thumbs up, thank you

He's the same as the injector, which doesn't look good.

There's no way around that.

It's not that he's missing a cylinder, it's that the cylinder is working, it's that the engine is shaking a lot, and then the exhaust pipe is suddenly ringing.

You've checked it.

Summary. Idle Control System Check:

1. Check whether the idle control valve is working properly.

2. Use the decoder to observe whether the throttle position signal is normal.

Gas System Inspection:

1. Use a decoder to check whether the mixture is too thin or too thick.

2. Use the decoder to check whether the pulse width of the fuel injection is normal.

The car burns oil, nothing to burn, and the engine shakes.

2. Use the decoder to observe whether the position signal of the throttle door is normal. Gas system inspection: 1. Use the decoder to check whether the mixture is too thin or too thick.

2. Use a dust-sensitive decoder to check whether the pulse width of the fuel injection is normal.

Do you have any other questions? We'll be happy to continue to answer your questions.

Summary. The intermittent engine idle jitter is mostly caused by the lack of cylinders in the engine, and the lack of cylinders is mostly caused by the blockage of the fuel injector, the ignition coil and cylinder line, and the spark plug.

When the car burns gas, the engine shakes badly, and the oil burns back to normal.

Dear, your base socks are good a lot of common problems of the Lu Ji car, some cars are not suitable for changing the gas, which is related to the ECU of the car, that is, the electronic control unit of the car, many parameters have changed after the gas change, the electronic control unit is not suitable and outputs the wrong instructions, this to brush the ECU may be good, but it is not guaranteed, many cars brush the ECU, the overall performance is not as good as before.

My question is that there is a shake in the idle speed, and there is a frustration in the speed of about 1200, and it is clear that the fault light can run a few liters normally, and there will be such a situation in the sky, please ask noisily what the reason is.

Pro: The intermittent shaking of engine idle speed is mostly caused by the lack of cylinders in the engine, and the lack of cylinders is mostly caused by the problems of the fuel injector and beam key to plug the slag and the plug, the dust cheating coil and cylinder line, and the spark plug.

The shivering of the car after the oil to gas is actually the engine idle instability, which can be checked one by one from the following hail aspects:

Idle Control System Check:

1. Check whether the idle control valve is working properly.

2. Use the decoder to observe whether the throttle position signal is normal.

Gas System Inspection:

1. Use a decoder to check whether the mixture is too thin or too thick.

Extended Information: Disadvantages of Oil-to-Gas Switching.

Due to the low energy density of gas hall cover fuel, natural gas vehicles carry less fuel and have a shorter mileage than gasoline vehicles. Most of the natural gas engines are modified by gasoline engines, so the power stop rate of gasoline vehicles often decreases by about 10% to 20% after switching to natural gas.

Since the natural gas vehicle is modified on the basis of the original gasoline and diesel vehicles, the fuel system of the original gasoline and diesel engine is mostly retained. Therefore, it is necessary to add a natural gas fuel system to the original car, especially the gas cylinder, so that the effective use of the original car trunk space is reduced, and the self-weight itself is also increased.

Natural gas is a gaseous fuel that is not easily stored and carried. For this reason, it is necessary to pressurize or liquefy for bottling, and it is also necessary to build a refueling station with a larger investment than gasoline and diesel gas stations, which is more difficult to refuel in areas where there is a shortage of refueling stations.
