Direct Injection (DI) Engine system

We offer high-efficiency engine control system complying with CO₂ regulations which will be enforced after 2010.

• Increased efficiency by combining DI fuel system with all kinds of variable valve technologies
• High-efficiency driving of auxiliary devices
• Control systems which can optimally drive various equipments

Fuel Control System, which will be a key for DI system, can be provided

• Controller into which injector, high-pressure fuel pump, and its drive IC have been integrated.
• Increased dynamic range by drive control optimal for injector characteristics.
• Improved accuracy of fuel injection volume control by pump and pipe systems which minimize the fuel pressure pulsation, and fuel pressure fast feedback control.

Injector spray, intake air flow, and piston surface specifications that are important for combustion development can be provided by spray and combustion analysis technologies accumulated in years.

• Determination of injector spray spec. (form, penetration) conforming to combustion chamber
• Suggestion of air flow spec. within combustion chamber
• Suggestion of the piston surface shape which can stabilize combustion

Improved quality of automotive embedded software which has been broadened and complicated

• High-quality software can rapidly be provided
• In embedding process, codes can be automatically generated from the control model
• Transfer-efficient software structures which has been divided and stratified for each function
