1. Description
The ACSD uses the contractive and expansive properties of thermo wax and the tension of a spring to automatically advance the injection timing in response to the coolant temperature, causing Read more VE Pump Options ACSD (Automatically-controlled Cold Starting Device)
Automotive Engine
TCV (Timing Control Valve) of Fuel Injection
The TCV renders the LST inactive if the vehicle is operated with a cold engine (coolant temperature below 6C (14F)) or at high altitudes (where the atmospheric pressure is below 93 kPa (70mmHg)). The purpose Read more TCV (Timing Control Valve) of Fuel Injection
LST (Load-Sensing Timer) of Fuel Injection
The LST changes the fuel injection timing in accordance with the engine load, and obtain the characteristic of advancing. The fuel is released from the orifice on the governor sleeve via the governor shaft Read more LST (Load-Sensing Timer) of Fuel Injection
M-M (Minimum-Maximum) Speed Governor ofDiesel Engine injection pump
The M-M speed governor controls the injection volume in accordance with the engine speed at minimum and maximum speeds. At other speed ranges, the fuel volume in accordance with the level of depression Read more M-M (Minimum-Maximum) Speed Governor ofDiesel Engine injection pump
Fuel Injection All-speed Governor
The all-speed governor controls the fuel injection volume at all engine speed ranges. The spill ring is moved by the governor, changing the effective stroke, resulting in an adjustment of the injection Read more Fuel Injection All-speed Governor
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
