Denso Accepts Engineering Award for Diesel Injection Technology

Order Reprints

The Institute of Electrical and Electronics Engineers (IEEE) awarded Denso Corp. the IEEE Medal for Environmental and Safety Technologies for its work to commercialize an electronically controlled injection system (diesel common rail), which has made a significant contribution to the spread of clean diesel vehicles.

The award ceremony was held June 18, 2016, in New York, and the award was accepted by Executive Vice President Masahiko Miyaki and Executive Directors Yukihiro Shinohara and Katsuhiko Takeuchi.

In 1995, Denso says it became the first company in the world to mass-produce an electronically controlled fuel injection system that achieved high-pressure and multistage injection. The common rail system improved emissions, which helped change people’s negative perception of diesel vehicles being “dirty.”

The common rail system helped expand the market share of diesel passenger cars in Europe. In 2013, Denso developed and mass-produced a system it says achieved ultra-high pressure injection of 250 MPa making emissions cleaner than ever before. Prior to this, in 2012, Denso mass-produced the i-ART (intelligent Accuracy Refinement Technology) system. A pressure sensor is built into the fuel injector to measure the injection pressure on a real-time basis and control the timing and injection volume for each injector, helping increase fuel efficiency and reduce the amount of hazardous substances in the emissions.
