VE Pump Diesel Engine Spare Parts Technical Articles

IMV is the abbreviation of fuel ratio control valve. IMV valve controls the proportion between fuel mount and oil return amount entering into high pressure chamber. This ratio is influenced by current magnitude through IMV. When current is zero, IMV is fully on. The aperture of IMV decreases with the increasing of cu...

Fault phenomenon: Diesel engine on an Iveco 40.10 car was assembled with VE distributor fuel injection pump. The plunger of head rotor was badly worn. So, the engine has difficulty for starting. Then change the head rotor and cam disc which has been worn seriously. However, diesel engine cannot start when the correct...

Fault Cases of Isuzu 4HK1 Diesel Engine Fault case 1: The engine cannot start after changing cylinder head gasket Fault phenomenon: Phase position of camshaft is not correct.

Audi was the first to say that, all of Audi’s new cars sold in China would carry auto-stop system and braking energy recovery system since 2012. Technical experts said, "In a sense, they are the micro hybrid, effectively reducing the energy consumption and carbon dioxide emissions." At present, all Au...

Diesel engine’s power depends on whether its each work cycle of the volume is enough and the fuel injection pump and injector work is in good condition. That is what we should consider when we deal with poor diesel engine power.   Due to insufficient air inflow, turbocharged inter-cold diesel Cummins d...

Injection needle valve is one of three couple precision elements of diesel engine fuel supply system. Its normal service life is more than 1000h. But due to improper use, it will often be worn and stuck after hundreds of hours or even dozens of hours. The main reasons of stuck injection needle valve are: ①The...

As is known to us, with the development of the national requirement for the pollution discharge, EUROⅢ (National Ⅲ) engines are used more widely in the special heavy vehicle. Because electronic-controlled engine technology content is higher, maintenance personals are required higher in technical level, especially...

Core prompt: The power of a diesel engine depends on whether there is enough air inflow at each work cycle as well as whether the injection pump and injector are under good work conditions or not. This is an important problem we should consider when dealing with the power failure of diesel engine. A Cummins turboc...

It’s difficult to judge intuitively the malfunction of high pressure pump during the working of diesel engine. In order to make beginner and personal with certain basic technique improve a lever to rule out the failure quickly, accurately and effectively, five exclusive methods are particularly introduced here ...

1. Fuel injection pump abrasion lead to diesel enter into oil Fault: engine oil level rises significantly with the smell of diesel oil. What is serious is that oil discharges from oil filer or ventholes. As for the piston fuel supply pump, diesel oil has only two ways to enter into the engine oil: diesel oil ca...
