What's wrong with the engine oil outage

Engine oil failure means that when the engine speed reaches a certain height,Top trade data trends reports such as 8000rpm, the driving computer will automatically stop supplying oil to the engine, so that the engine speed is not It can exceed the limit value, which is specially designed by the manufacturer to protect the engine.

Overspeed oil cut-off control, when the engine speed exceeds the design (set) speed, the engine will cut off the oil supply. When the engine computer detects that the engine speed has exceeded the set speed, it will control the fuel injector to stop the injection.

The car has a brief oil outage when driving, mainly including: oil line problems, focusing on checking the fuel injector, throttle valve, line problems, focusing on inspectionCheck the ignition coil, high-voltage package, brake light switch. Some models have priority on the brake system, and the brake light may also be triggered when vibration occurs.

What is the reason for the interruption of oil and re-stepping on the accelerator

It may be that the accelerator pedal position sensor or throttle position sensor is faulty, and the idling control valve and engine computer failure will also cause this. Kind of phenomenon. It is recommended to contact the 4S store for inspection and maintenance. The vehicle's oil outage protection is to set the maximum speed, and the computer will judge whether the speed exceeds the predetermined value.

First of all, check the fault of the fuel system. The possibility is mainly caused by the poor oil supply of the fuel pump. First of all, check the amount of fuel injection, which is an inspection to measure whether the fuel pressure value is normal.Then check the smooth operation of the gasoline filter and take off the fuel filter to check.

The car suddenly ran out of oil, and it will be fine after a while. What is the reason? The oil outage of the car may be caused by high brake sensitivity. It may also be related to the priority braking system on the car. If you step on the accelerator while driving, the accelerator will directly cut off the oil when braking urgently, which is also designed for safety reasons.

Hello. In this case, it is a lack of cylinder and oil. After restarting, the troubleshooting shows that there is a problem with the system that needs to be tested and repaired for the intake system and the fuel system. The data stream can be read through the computer diagnostic instrument. Check the accuracy of the data or check whether there is a fault code. I hope my answer will be helpful to you and hope you can adopt it.

If your motor vehicle suddenly runs out of fuel while drivingThe throttle is fine. This possible reason is that your fuel injector is blocked or the fuel injector is innocently glued. It is best to clean the oil road and fuel injector.

Engine overheating and oil cut-off

1. Reason: Heat dissipation water caused by long-term or high-speed operation of the engine The temperature of the box is overheating, and stillIf the automatic transmission overheats, it will prompt the signal light and issue a sound warning. In particularly serious cases, the internal computer of the car will cut off the power supply and stop the oil supply. If this is often the case, it is recommended to check the water tank, transmission fluid, engine oil, etc.

2. Will. If the temperature of the Qianjiang Sai 250 engine is too high, it cannot be used normally. It will cut off the oil and cannot continue to be driven. It needs to be repaired. This engine is a single-cylinder water-cooled engine, with a maximum horsepower of 29 horsepower and a maximum power of 5KW. The front and rear ABS support, and a fuel tank volume of 15L.

3. Too much carbon accumulation. Too much carbon accumulation in the valve and combustion chamber is also easy to cause the engine oil to cut off, and the carbon accumulation needs to be cleaned up in time. The engine runs for a long time. Due to long-term or high-speed operation, car engines causeIf the temperature of the heat sink is overheated or the automatic transmission is overheated, it will also lead to oil outage, and you need to stop and rest in time.

4. If this is often the case, it is recommended to check the water tank, transmission oil, oil, etc. Then how to predict in advance that the engine will be out of oil? In fact, the dangerous speed of the engine is generally marked in a red area on the tachmometer. When the pointer enters the red zone, the engine will generally stop injecting fuel.

How does engine oil cut-off protection work

1. Engine oil cut-off protection is to use compressed air to directly control the fuel injectors of each cylinder, so that the fuel in the high-pressure oil pipe can be bypassed in case of failure, so that it does not enter the spray. Oil engine - does not enter the cylinder to ignite and burn - the diesel engine stops running.In order to protect the engine.

2. The engine oil cut-off protection is to directly control the injector of each cylinder with the compressed air body, so that the fuel in the high-pressure oil pipe can be bypassed in the event of failure, so that it does not enter the fuel injector - does not enter the cylinder ignition combustion - the diesel engine stops running. So as to protect the engine.

3. The basic working principle of engine oil cut-off protection: Most of the oil cut-off protection of small and medium-sized diesel engines is to install a small cylinder on the throttle lever. The piston of the small cylinder is connected to the trottle rod. Normally, the small piston rod will not affect the throttle adjustment action of the main throttle rod.
