How to troubleshoot the black car of the sprinkler exhaust pipe

When the sprinkler 's exhaust pipe has black smoke out of trouble, should pay attention to those matters? The black smoke emitted from the sprinkler's exhaust pipe may be due to the engine's non-uniform engine speed and inefficiency resulting in black smoke, and there may be unusual percussive sounds and intensification. The situation of fuel consumption.

The reason for this type of failure in the sprinkler may be due to the overloaded operation of the vehicle's diesel engine oil and the resulting increase in fuel consumption resulting in the emission of black smoke; the quality of diesel fuel injected by the sprinkler is not up to standard, resulting in The combustion is not complete. After the intake system is blocked, the intake air volume of the cylinder will be insufficient and black smoke will appear. The quality of the atomization of the injector will be relatively poor, the condition of the oil drips will appear, and the supercharger will fail. As a result, the supply pressure is insufficient. The valve clearance is not properly adjusted or the injection timing is misaligned. When black smoke is emitted from the exhaust pipe of the sprinkler, most of the reason is because the fuel supply is too much, because incomplete combustion occurs in the absence of oxygen. Therefore, part of the carbon elements are suspended and free. The situation was followed by exhaust emissions and regrets the formation of black smoke. The following method can be used for exclusion:

1, because the sprinkler diesel fuel quality is too bad, should replace the appropriate diesel.

2. After the air intake system of the vehicle has become clogged, it is necessary to immediately replace or clean the air filter of the sauce.

3, valve gap adjustment is not appropriate after the failure should be promptly carried out inspection and maintenance.

4. After the turbocharger fails, troubleshoot and repair it in time.

5. When the fuel supply of the sprinkler 's diesel engine is not correct, it should be adjusted in accordance with the relevant regulations.
