Product Description
The Perkins Engines were developed in order to
provide gas engines for generator set applications.
The engines have the ability to burn a wide variety of
gaseous fuels.
Fuel System
The fuel is delivered to the gas control valve. The gas
must be at a constant pressure and the gas pressure
must be stable. The pressure must be within a range
of 5 to 25 kPa (0.72 to 3.6 psi). Higher pressure will
need to be reduced with an additional gas regulator.

(12) Throttle
(13) Oil drain plug
The venturi is located in the gas mixer body
i02885810
immediately before the turbocharger. As air is
accelerated through the venturi gas is mixed with the
air. This mixture is compressed by the turbocharger.
The mixture passes through the tumbulator, and the
charge coolers, and into the inlet manifolds. The
speed and the load is governed by electronically
controlled throttle valves.
A digitally controlled gas valve maintains the air/fuel
ratio. This system is adjustable. Refer to Systems
Operation, Testing and Adjusting for details. This is
the only means of adjusting the exhaust emissions.
Ignition System
The engine is equipped with an Electronic Ignition
System (EIS). The EIS provides dependable firing
and low maintenance. The EIS provides precise
control of the following factors:
