ENGINE — 2JZ–GE ENGINE
2. Air Assist System
This system was adopted to the 3VZ–FE engine for the ’92 Camry, but it has also been adopted for the new Toyota
Supra to reduce HC emissions. This system directs part of the air which bypasses the throttle valve to the injection
port of the fuel injector. The full mixed with this air flow in thus injected into the cylinder, helping to accelerate the
atomization of the fuel.
3. Fuel Injector
The 2–hole type fuel injectors, used in the 7M–GE engine, are also used in the 2JZ–GE engine to maintain good
engine response.
In the California specification models, together with the use of the Air Assist System, a fuel injector with adaptor
is used. Air introduced from the IAC [ISC] valve, air hose and air gallery flows through the air chamber formed
by the O–ring and insulator under the fuel injector and then is mixed with the fuel. This design promotes
atomization of the fuel.
