2.7 Electronic Control Unit (ECU) and Electronic Parts Introduction

ECU
Function description:
ECU collects inlet manifold pressure (MAP),
inlet manifold temperature (MAT), engine
phase, revolving speed, outlet water
temperature, exhaust oxygen concentration
and other signals and controls the action of
electronic throttle, ignition timing and ignition
orders after calculation so as to accomplish
electronic control of engine.
Engine control unit (ECU) shall be installed
in control panel to realize real-time
monitoring of engine parameters.
Technical parameters:

Working voltage: 24V;

Working environment: -40
℃～
105
℃
.

To prevent any damage to ECU, it is
forbidden to carry out hot plugging operation
on ECU.

Inlet temperature, pressure sensor (T/MAP)
Function description:
T/MAP sensor integrates pressure and
temperature measurement. Engine control
unit (ECU) uses sensor signals to calculate
engine’s mixture air input.
Technical parameters:

Applicable pressure: 20 kPa
～
300kPa;

Applicable temperature: -40
℃～
130
℃
;

Voltage: 4.75V
～
5.5V.
