2.4L LPG Engine System Operation
Overview
Based on the various inputs, the ECU determines the
appropriate amount of air, fuel and spark advance to
supply the requested engine speed. The calculations are
based on a speed/ density calculation that uses MAP,
MAT, engine speed, and volumetric efficiency to
determine the airflow into the engine, and therefore, the
optimum fueling for the engine. Engine RPM is
determined from the crankshaft position sensor. The
crank sensor is a reluctor sensor. The sensor generates
60 -2 pulses per engine revolution. The ECU translates
the 60 -2 pulses into engine RPM and crankshaft
rotational position. The ECU then commands the
appropriate throttle angle from the electronic throttle and
the appropriate injector pulse width.
Injector phasing is based on the camshaft sensor. The
camshaft sensor is a Hall Effect sensor that sends a
signal one per camshaft revolution, or once every 2
engine revolutions. The ECU then monitors the Oxygen
sensor to make corrections for minor errors in the fueling.
The ECU has the capability of both long term and short
term fueling corrections. Long term is stored in memory
and is not lost at key “OFF.”
