Diesel engines combine excellent fuel economy and power, and their popularity is growing, especially in Australia.

The development of the common rail system is a landmark in significantly improving the diesel engine capabilities. DENSO launched the world's first common rail system in 1995 and since then has been actively involved in developing advanced diesel engine technologies to meet customer needs as well as stringent worldwide emission regulations.

DENSO's diesel engine management system will expand to include intake air and exhaust gas recirculation (EGR) management and exhaust gas treatment, in addition to the common rail system as a core of the management system.

COMMON RAIL SYSTEM

The common rail system accumulates high-pressure fuel in the common rail and injects the fuel into the engine cylinder at timing controlled by the engine ECU, allowing high-pressure injection independent from the engine speed. As a result, the common rail system can reduce harmful materials such as nitrogen oxides (NOx) and particulate matter (PM) in emissions and generates more engine power.

DENSO leads the industry in increasing fuel pressure and maximizing the precision of injection timing and quantity, achieving cleaner emissions and more powerful engines. DENSO's common rail systems are supplied to a variety of vehicles including passenger cars and commercial vehicles.

DENSO Diesel Fuel Injection offers:

• The world's highest injection Common Rail System (CRS) with a maximum pressure of 1800 Bar, (5 times injections per cycle) which translates to a drastic reduction in Nitric Oxide (NOx) and Particulate Matter (PM).
• The latest versions of DENSO's Common Rail Systems which easily meet EURO 4 Emission requirements without the use of expensive Diesel Particulate Filters.
• A Common Rail System which is the lightest of its type.
• A commitment to ongoing quality improvement, greater reliability and systems designed to meet the increasingly strict emission laws.
