Cummins QSX15 ISX15 Excavator Diesel Engine Electronic Control
Module ECM 3684275
How does ECM work?
The Engine Control Module (ECM), also called the Engine Control
Unit (ECU), ensures that your vehicle operates at optimal
performance. The ECM monitors most of the sensors in the engine bay
in order to manage your vehicle’s air-fuel mixture and regulate the
emission control systems.
The ECM regulates four main parts of your vehicle’s operating
systems: air-fuel ratio, idle speed, variable valve timing, and
ignition timing. In terms of the air-fuel ratio, the ECM uses
sensors to regulate the oxygen to fuel ratio detected in your car’s
exhaust to detect an engine rich/lean reading. Some of these
sensors include the mass airflow sensor(s), the oxygen sensor(s),
air-fuel sensor(s). For the idle speed, the ECM relies on sensors
loed by the crankshaft and camshaft(s) that track your vehicle’s
RPM and engine load by monitoring the speed of rotation of the
engine. The variable valve timing system controls when the valves
are opened in the engine to either increase power or fuel economy.
Lastly, the ECM controls the ignition timing, this is the position
at which the spark plug is fired within the combustion cycle.
Precise control of this timing allows for more power and/or better
fuel economy.
