Isuzu's New 12.0L Micro-Computer Controlled Turbocharged Diesel Engine 840510
Isuzu Motors Limited introduced in the Japanese market a new micro-computer controlled turbocharged 6RA1TC diesel engine which powers new Isuzu heavy-duty trucks in 1983.
This engine has successfully achieved both fuel economy and vehicle performance. This was realized by the combination of the newly developed micro-computer controlled fuel injection system and turbocharged air-to-air intercooled four valve low friction diesel engine.
The purpose of the computer control system is flexible and precise control of fuel flow rate and fuel injection timing. This provides maximum engine performance and driveability, best fuel economy combined with the gearing of the vehicle, and easy operation for drivers. Additionally, this engine offers the following features:
Good cold startability.
Constant speed Cruise Control.
Automatic schedule idling speed during warm-up.
Stable low speed idling.
Light and quick throttle response.
