Unit fuel injector for IC engine

摘要

The fuel injector (10) includes a pump mounted in an injector housing (11) and having a plunger actuable by a cam shaft (28) of the engine. The plunger reciprocates in a pump chamber communicating with an injection nozzle (12) received by the housing and a cylinder head bore (14). - A fuel inlet passage in the housing communicates with the pump chamber to supply fuel under low pressure. An exteriorly actuable pushrod (36) reciprocates the plunder and is disposed between the camshaft and an actuating arm.
