Truck speed is capped at 1800 RPM, fault analysis and solution

Failure case

When the car starts running, no matter how hard you press the gas pedal, the top speed is 1800 RPM.

Failure analysis

Check the oil and water separator, the top rubber gasket is worn

It brought a lot of trouble when disassembling.

The car’s three deputy factory filter elements have almost been

Become a completely blocked state, inferior oil and water separator

Unable to separate the diesel and water effectively, after disconnecting the oil pump,

The oil inlet of the oil pump has almost been blocked by a large amount of impurities,

When the vehicle is running normally, the oil pump is almost difficult to guarantee

Normal fuel supply to the engine.

Failure to solve

After cleaning the oil pump and replacing the genuine filter element,

Engine speed limit trouble shooting.

Serious plugging of oil-water separator and diesel filter element,

The actual flow of diesel oil in the entire oil pipeline is minimal.

In this case, the engine just starts,

It’s almost impossible to get more performance out of it.

If the fuel supply system of the diesel engine does not pay attention to technical maintenance at ordinary times, no matter which link is out of order, it will lead to poor oil supply or the engine can not start normally, so often maintain the diesel filter can effectively reduce the damage of diesel to the engine.
