2007 JAC Ruifeng Diesel 2.5, the engine works for a long time and then it appears that the speed is

Introduction 2007 JAC Ruifeng Diesel 2.5, the engine works for a long time and then it appears that the accelerator is applied and the speed is only idle. There are several possibilities. One is your diesel filter.

2007 JAC Ruifeng Diesel 2.5, the engine works for a long time and then it appears that the speed is

There are several possibilities. One is that your diesel filter is dirty. It should be noted that there are three diesel filters.

There is a fuel pipe connected from the fuel tank. Next to the fuel tank, there are two more on the engine.

That is, on the oil inlet pipe. Another possibility is that the big pump is dirty and the big pump must be calibrated

JAC Ruifeng gasps for air at idle speed, and it is fine after 1000 rpm

The engine idle speed is unstable. In addition to considering In addition to the main influencing factors such as oil, electricity, and cylinder pressure, inaccurate timing, unsealed valves, leaking cylinder gaskets, improper valve adjustment, poor valve hydraulic ejector pins, cylinder blow-by, and connecting rod bending and deformation should not be ignored. Don't think that oil, electricity, cylinder pressure and timing are normal, so don't compare normal values. This will affect your thinking and lead to wrong judgments. For example, if the throttle pressure sensor fails, this phenomenon will occur. Find it accurately and do not disassemble it blindly

The reason why it is enough to refuel to 1000 rpm is:

A situation caused by a car's idle motor handling failure. The solution is: If the car's idle motor fails, you need to go to the car's 4S shop or repair shop in time to repair the car's idle motor to solve the problem of poor car idling.

Idle jitter, increased fuel consumption, uneven acceleration, etc. are most likely due to carbon deposits in the engine.

The engine needs to burn gasoline to produce kinetic energy to drive the vehicle, so "carbon deposition" is actually inevitable. Carbon deposition is caused by wax, colloid and other impurities in the gasoline staying in the combustion chamber for a long time. After repeated high temperatures, The black solid left behind after burning.
