ENGINE-ECU

Engine-ECU is installed in the engine room. 
Engine-ECU judges (calculates) the optimum control 
to deal with the constant minute changes in driving 
conditions based on information input from the sen-
sors and drives the actuator. Engine-ECU is com-
posed of 32-bit microprocessor and Random Access 
Memory (RAM), Read Only Memory (ROM) and 

Input /Output interface. Engine-ECU uses 
flash-memory ROM that allows re-writing of data so 
that change and correction of control data is possible 
using special tools. It also uses Electrically Erasable 
Programmable Read Only Memory (EEPROM) so 
that studied compensation data is not deleted even if 
battery terminals are disconnected.

SENSOR

M2132001001472

AIR FLOW SENSOR

Air flow sensor is installed in the air intake hose. Air 
flow sensor is composed of an extremely small heat-
sensing resistor. The air flow sensor controls the 
amount of electric current flowing into the heat sens-
ing resistor to keep the heat sensing resistor at a 

constant temperature to the intake air temperature. 
When the air mass flow rate increases, the air flow 
speed is higher and also the amount of heat transfer 
from the heat sensing resistor to the air increased. 
Therefore, the air flow sensor increases the amount 
of electric current to the heat sensing resistor. Thus, 
the amount of electric current increases in accord-
ance with the air mass flow rate. The air flow sensor 
measures the air mass flow rate by detecting the 
amount of electric current. The air flow sensor ampli-
fies the detected electric current amount and outputs 
it into the engine-ECU. Engine-ECU uses this output 
current and engine speed to calculate and decide 
basic fuel injection time. Sensor properties are as 
shown in the figure.
