Injection Pump - Isuzu NHR 4J Series Workshop Manual

6C - 4 ENGINE FUEL

INJECTION PUMP

A Bosch Distributor Type Injection Pump is used. A
single reciprocating/revolving plunger delivers the fuel
uniformly to the injection nozzles, regardless of the
number of cylinders.
The governor, the injection timer, and the feed pump
are all contained in the injection pump housing.
The injection pump is compact, light weight, and
provides reliable high-speed operation.
An aneroid compensator is available as an option for
vehicles to be operated at high altitudes. It adjusts the
fuel and air mixing ratio.
