DESCRIPTION:
Bosch Fuel Injection Rqv-Rquv-Ep-Rsv Equipment
General
The diesel engine draws only air in during the suction stroke. During the compression stroke this air is heated to such a high temperature that the diesel fuel injected into the engine toward the end of the compression stroke ignites of its own accord. The fuel is metered by the fuel injection pump and is injected under high pressure through the injection nozzle into the combustion chamber.
Fuel injection must take place:
• in an accurately metered quantity corresponding to the engine load.
• at the correct instant in time.
• for a precisely determined period of time, and
• in a manner suited to the particular combustion process concerned.
Maintenance of these conditions is the function of the fuel injection pump and the governor. The quantity of fuel injected into the engine during each plunger lift is approximately proportional to the torque of the engine. This fuel delivery is adjusted by turning of the pump plungers, each of which has an inclined helix machined into it. As a plunger is turned, its effective stroke is varied.
- The plungers are turned by means of the control rod acting through either a Set of gear teeth or some other transmission part. (See Technical Instruction VDT-UBP 001/15 B for a detailed description of the construction and operation of the Bosch PE-type in-line injection pump.)
- In a motor vehicle the control rod is connected to the accelerator pedal through the governor and a linkage: when the accelerator pedal is pressed down, the pedal travel is converted to a corresponding control-rod travel (Fig. 2). Stationary engines can be operated with the governor control lever or by an electric speed-control device.
