ECU |
An Engine Control Unit (ECU), also known
as Engine Management System (EMS) is an electronic
device, fundamentally a computer, that is part of an internal
combustion engine, which reads several sensors in the engine and
uses the information to control the ignition systems of the
engine. This approach allows an engine's operation to be
controlled in great detail, allowing greater fuel efficiency,
better power and responsiveness, and much lower pollution levels
than earlier generations of engines. Because the ECU is dealing
with actual measured engine performance from millisecond to
millisecond, it can compensate for many variables that
traditional systems cannot, such as ambient temperature,
humidity, altitude (air density), fuel octane rating, as well as
the demands made on it by the driver. In addition, to a large
degree it is able to compensate for the gradual wearing of the
engine as it ages, which in practice allows it to extend engine
life to two or three times that of engines of twenty years ago.
