Cylinder failure is a common failure of diesel engines, which refers to a few cylinders in multi-cylinder engines do not work or work intermittently. This kind of failure will lead to unstable diesel engine, shaking, sound discontinuous, uneven, weak, easy to stall, emission of black smoke and with "raw oil flavor".
The cause of cylinder failure can be divided into two aspects, one is the cause of the machine, refers to the end of the compression stroke can not be reached at the end of the temperature and pressure of the due hair for; two is the cause of the oil supply system.
When a diesel vehicle has a cylinder shortage symptom, we need to check the sealing of the cylinder head, check the sealing of the piston ring and cylinder, check the cylinder pressure, as well as check the work of the injector to determine the specific cause of the failure. If we find that there is a problem with the oil supply system, we need to check the injection pressure of the injector and the sealing of the injector and cylinder head to ensure that the diesel engine works properly.
In order to avoid the occurrence of missing cylinder failure, we need to regularly check and maintain the diesel engine, pay attention to keep the oil and filter clean, replace the air filter in time, and maintain the normal working condition of the engine in order to minimize the occurrence of failure.
