TECHNOLOGY Common Rail System

Diesel engines have the advantages of good fuel
efficiency and low CO2 emissions. Therefore, DENSO
developed a diesel engine management system to
further clean up emissions w hile improving fuel
efficiency. This system is a product of various forms
of advanced technology. Among them is the common
rail system employed in the fuel injection.
1,800 bar injection pressure is equivalent to
the water pressure of a depth of 18,000 meters
deeper than the Mariana Trench, the world’s
deepest ocean bottom. High response injectors
by electronic control feature the highly
accurate multiple injections (five times). As a
result, particulate matter and NOx are
markedly reduced, while improvements in fuel
efficiency and torque are achieved. Plus, engine
noise and vibration are also reduced. |
