Denso Corp. says its ultra-high-pressure diesel common rail fuel injection system can improve fuel efficiency 3%, lower oxides of nitrogen formation by 8% and slash particulates 50% compared with the company's previous-generation technology.
The system, which will hit the market later this year, boasts a record high 2,500-bar (36,300 psi) injection pressure.
The higher pressure allows finer fuel atomization, which improves combustion efficiency. Denso redesigned the system's architecture to reduce by 90% the amount of fuel circulated back to the fuel tank after being used to lubricate components.
The improvement reduced the workload for the fuel pump, thus enabling the company to develop a pump that is similar in size but more efficient than previous units.
Denso describes itself as the first to commercialize diesel common rail systems in 1995. It also says it set industry records for high-pressure systems in 2002 (1,800 bar) and 2008 (2,000 bar). The company is developing a 3,000-bar (43,500-psi) system.
