The Institute of Electrical and Electronics Engineers (IEEE) awarded DENSO the IEEE Medal for Environmental and Safety Technologies for being the first company in the world 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 was presented at a ceremony held on Saturday, June 18, in New York, and was accepted by Executive Vice President Masahiko Miyaki and Executive Directors Yukihiro Shinohara and Katsuhiko Takeuchi.
In 1995, DENSO 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 significantly improved emissions, which helped change people’s negative perception of diesel vehicles being “dirty.”
Notably, the common rail system helped expand the market share of diesel passenger cars in Europe. In 2013, DENSO developed and mass-produced a system that achieved ultra-high pressure injection of 250 MPa making emissions cleaner than ever before. Prior to this, in 2012, DENSO became the first company in the world to mass-produce 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.
DENSO says it will continue its efforts to increase fuel injection pressure and accuracy in order to meet the increasingly strict emission regulations around the world and the growing need for higher fuel efficiency. Furthermore, DENSO will deliver products that meet the regional needs of its customers around the world.
