VE Pump Mechanical Governor (Fuel Injection)
It is necessary to control the fuel injection volume in accordance with the effort that the accelerator pedal is depressed and engine load as the output of the diesel engine is controlled by the fuel injection Read more VE Pump Mechanical Governor (Fuel Injection)
Diesel Engine Automatic Timer (Injection Timing Control)
As in the case of gasoline engine ignition timing, diesel engine injection timing must be advanced (or retarded) in accordance with the engine speed in order to obtain optimum performance. Advancing or Read more Diesel Engine Automatic Timer (Injection Timing Control)
Diesel Engine Fuel Cut-off Solenoid
The fuel cut-off solenoid valve opens and closes the fuel passage leading to the suction port. (The valve remains open while the ignition switch is on.)
1. Fuel cut-off solenoid on
The battery voltage Read more Diesel Engine Fuel Cut-off Solenoid
Feed Pump and Regulating Valve
1. Feed pump
The vane type feed pump consists of four blades and a rotor. The rotor is driven by the drive shaft, and the blades push against the inner wall of the pressure chamber due to centrifugal Read more Feed Pump and Regulating Valve
Diesel Engine Injection Pump System
The injection pump pumps the fuel to each injection nozzle.
The injection pump functions to control the fuel injection volume and timing.
1. Fuel suction
The feed pump draws the fuel from the Read more Diesel Engine Injection Pump System
Other Diesel Engine Equipment Intake Shutter
1. Description
Some diesel engines use an intake shutter. The intake shutter has following functions.
(1) Stops vibration immediately after engine is turned off. In diesel engines, air continues Read more Other Diesel Engine Equipment Intake Shutter
Deisel Engine Vehicles Glow System
1. Glow indicator light description
The glow plug indicator light is mounted inside the combination meter. When the light goes off, it informs the driver the engine is ready to be started.

Diesel EnginePreheating System
1. Necessity of preheating system
At a cold engine starting, the compression heat escapes from the compression chamber even if there is adequate compression. In some cases, the injected fuel does not Read more Diesel EnginePreheating System
Fuel dribble (dripping) after injection
This occurs when the fuel supply is not precisely cutoff at the end of fuel injection and fuel particles are accumulated on the tip of the nozzle. If fuel dribble occurs after fuel injection, the fuel Read more Fuel dribble (dripping) after injection
