TECHNICAL DATA
ENGINE
K21 (2.1 liter) or K25 (2.5 liter) gasoline/LPG,
4-cylinder, in-line engines with Engine Con-
centrated Control Systems (ECCS) exceed
EPA emissions standards. These low-RPM,
high-torque industrial engines offer reduced
maintenance requirements, exceptional
emissions controls, fast acceleration, high
performance, reliable durability and
enhanced serviceability.

• There are three engine fuel choices: gaso-
line multi-port fuel injection, LPG single-port
(throttle body) fuel injection, or a dual-fuel
system with easy switching at the fl ip of
a switch. All engines are equipped with
3-way catalytic converters and closed-loop
exhaust systems.
(throttle body) fuel injection, or a dual-fuel
system with easy switching at the fl ip of
a switch. All engines are equipped with
3-way catalytic converters and closed-loop
exhaust systems.
• All engines utilize an ECCS that continu-
ously monitors data from the fuel pressure,
accelerator throttle position, mass air-fl ow
sensor, and heated oxygen sensor – for
improved fuel economy, smooth operation,
reliable starting in cold weather, and high
performance throughout the operating
range. An electronic throttle governor pro-
tects the engine against over-rev damage.

• An engine coolant temperature sensor
and controller protects the engine against
damage due to high engine temperature
by automatically limiting engine speed
during high-temperature operation. If the
engine coolant temperature exceeds safe
operation temperature, the engine will be
shut down. An illuminated indicator on the
instrument console indicates high-temper-
ature operation, and gives the operator
warning of engine shutdown.
