Main technical characteristics of plunger：
The cylindrical surface of plunger milled linear or spiral chute, chute connected the high pressure and low pressure chamber of pump. Two round holes on plunger sleeve connected with low pressure chamber of injection pump. Plunger do reciprocating linear movement drived by camshaft to achive fuel supply, boost pressure,fuel return process.

Main technical characteristics of delivery valve：
Delivery valve is a one-way valve, the upper conical surface seal with valve seat,
isolate the high pressure fuel pipe and plunger. When the fuel pressure is higher than the spring of delivery valve and residual pressure of high pressure fuel pipe, the delivery valve is pushed out, high pressure diesel into the high pressure fuel pipe, sprayed into the combustion chamber by injector, then fuel pressure dropped, delivery valve is quickly closed, stop the fuel supply

Main technical characteristics of Nozzle：
Nozzle is a normally closed valve, the needle valve up and down movement to control the open and close of nozzle. Needing injection, control valve open, diesel high speed jet from the annular clearance between the valve head shaft needle and nozzle holes, into the combustion chamber. Nozzle is one of the key components which influence the performances of diesel engine. |
