Fault Case One: Engine cannot start after changing the cylinder head gasket. Fault phenomenon: The phase of camshaft is not correct. Fault cause: The installation of camshaft is not correct. Fault analysis: Due to the uniqueness of CMP signal (CAM shaft angle sensor), the engine won’t start if the installati...

1. Prevent Crushing Use triangular wood or brick to mat the wheel while repairing the vehicle. Secure the support if you use a jack to jack wheels. Observe whether there is someone or obstacles around when releasing the jack. Support inclined truck before checking the tube of hydraulic trunk.   2. Prevent Sca...

Electrical components and wiring harness of electronically controlled diesel engine must keep dry and off water, oil and dust. The routine maintenance of common rail electronically diesel engine should be noted the following:   1. Please remember to turn off ignition switch before plugging connector plugins of...

1. Chemical descaling: chemically dissolve the rust layer. The general technology of chemical descaling: Oil removing→Thermochemistry→Cold Wash→Descaling→Cold Wash→Neutralizing→Runny Wash→Passivation→Dry→Oil seal anti-rust.   2. Mechanical descaling: remove the...

Common rail technology is a method of oil supply that high pressure oil pump, pressure sensor and ECU consist of closed-loop system, separating the production of injection pressure from injection process completely. High pressure oil pump transmits high pressure fuel to public delivery pipe, controlling oil pressure ...

Symptom: The diesel engine (equipped with VE distributor pump) on a NHK notchback manufactured by Jiangxi Isuzu has good starting performance and it is quite normal when cooling. However, the engine losses its power gradually and even has flameout after running for a period of time.  Fault diagnosis: Burning...

Fuel injection pump has three kinds of type such as inline type, distributor type, monocoque type. No matter what kind of products it is, the most important part is the pump. The quantity, pressure and time of fuel pump must be very precise and automatically adjust according to the load. Fuel injection pump is a sort...

Eight Phenomena of Common Faults for High Pressure Common Rail: I. Gear pump doesn’t outlet oil when fuel system need rule out the air again for electronically controlled high pressure common rail diesel engine. Troubleshooting Methods: 1. Gear pump doesn’t work without fuel. Thus we have to add som...

First, Worn Fuel injection pump makes the diesel oil enter into engine oil.  Oil temperature increases significantly accompanied with smell of diesel oil. The oil will leak from oil mouth or vent when it’s serious. For piston supply pump and diesel oil entering into engine oil, there are only two reasons...

VE distributor pumps belong to precision machinery, which contain many high precision parts and matching parts. They should be used and maintained correctly in order to guarantee the performance and longevity of engines and fuel injection pumps.   1. Protective oil on drive shaft should be eliminated before ...
