DENSO Fuel Injection
DENSO's leadership in diesel common rail technology is unsurpassed in the industry. In 1995, DENSO launched the world's first diesel common rail injection system for trucks. The following year, it began supplying diesel common rail injection systems for passenger cars.
Diesel engines with DENSO's common rail system are:
By injecting fuel at 1800 bar (26,000 psi), regardless of engine speed, DENSO's common rail system produces higher power and more low-end torque.
The injectors can deliver fuel at intervals of 0.4 miliseconds, which allows up to five injections per cylinder per combustion cycle. This reduces diesel engine noise at idle.
The combination of high fuel pressure and precise control of fuel combustion through multiple injections reduces emissions, particulate matter and nitrogen oxides.
