Breath of fresh air
Several new technologies to clean up engines have been showcased by OEM and aftermarket supplier Delphi at a trade show this week.
The developments include advances in fuel injection and engine control systems that reduce carbon dioxide and nitrogen oxide emissions, helping automakers meet demanding new regulations. Among the discussions at the Aachen show in Germany was a presentation of technical papers on the latest diesel common rail fuel systems.
“The future of powertrain technology remains the subject of lively debate,” said Mary Gustanski, director of Engineering, Customer Satisfaction, Program Management and Operations for Delphi Powertrain Systems. “We can see some convergence in diesel and gasoline strategies as both now use direct injection, turbocharging, downsizing and even 3-cylinder engines. Heavily boosted, downsized engines provide high power density with low CO2 emissions, but the higher combustion temperatures and pressures involved make the reduction of NOx emissions more challenging. Delphi’s mission is to deliver undiminished vehicle performance while satisfying fuel economy needs and emissions regulations.”
