OUTLINE Control lever Full-load adjusting screw Governor lever Magnet valve Drive shaft Distributor head Feed pump Plunger Roller holder Cam disk Timer Plunger spring Delivery valve / | Fig. 1 VE type injection pump construction With the PE type (in-line type) injection pump, In comparison with the the injection pump has less than half the number of parts, and was order to satisfy the need for a small, number of pump elements (plunger assemblies) must be the same as the number of engine cylinders. However, with the VE type (distributor type) injection pump, the number of plungers has no relationship to the number of engine cylinders, and there is only one plunger.

This single plunger reciprocates while rotating, and fuel oil is injected into each cylinder through the injection pipes in accordance with the engine's firing order. As well as this, the governor, timer, feed pump etc. installed on the outside of the PE type injection pump are equipped within the VE type injection pump. component PE type, the VE type developed in light- weight and high-speed injection pump. In response to operator requirements, it was possible to design a pump with accelerator “feeling” close to that of gasoline vehicles.

A VE type injection pump for direct injection system engines has recently been developed, and is expected to be adopted in a wide range of fields, including construction machinery, medium-sized trucks etc.

Features 1. The injection pump is small and lightweight, and has a small number of component parts (compared to conventional in-line injection pumps). er Injection pump type VE Distributor type VM Distributor type PE4A In-line type PE6A In-line type Weight (kg) LengthxHeight Size (mm.)

High speed operation up to engine speeds of 6000 r.p.m. is possible. 4.Matching of the engine's torque characteristics can be easily performed. 5. Its construction versed.

prevents fuel injection if by any chance the direction of engine rotation is re- 6. Adaption to various engine performance requirements is simplified. Control mechanisms can be independantly installed e.g. torque control device, load timer, boost compensator. 7. Because injection is stopped by turning the ignition switch (key) off, immediate stopping of the engine is possible. 8. Fuel oil lubrication (maintenance free) As lubrication of the inside of the injection pump is performed by fuel oil contained in the pump chamber, special lubricating oil is not necessary. Because of this, no time is lost through the usual inspections. EEN
