. Summarize

The system, referred as “

λ

Speed Density”type (running speed, air density, mixture control), is

designed to perform the control for injection and distributorless ignition. According to the following figure
(figure 159) of Single Port Injection System, three basic parts are included as the following:

1. “I.A.W.6F

。

”Injection System ECU.

2. “20MM12”Single Port Injection System throttle valve body.

3. Two “BAE 800 AK”Ignition coil. The whole system includes fuel pump, fuel filter, RPM

sensor, absolute pressure sensor,

λ

sensor and so on.
