Delphi Fuel Pumps Compatible with New E15 Measure from EPA
Delphi announced today its OE quality fuel products are compatible with the new E15 measure approved last Friday by the U.S. Environmental Protection Agency (EPA) to increase the amount of ethanol currently blended in fuel from 10 percent to 15 percent for all light-duty vehicles built in the last decade. This includes approximately 166 SKUs covering 32 million vehicles from 2001 to current model year. Due to Delphi's stringent original equipment...
Delphi's Solid Oxide Fuel Cell Auxiliary Power Unit Named to EPA's Emerging Technology List
Delphi Automotive's Solid Oxide Fuel Cell (SOFC) Auxiliary Power Unit (APU) has been designated an Emerging Technology by the U.S. Environmental Protection Agency (EPA), recognizing the technology as a potentially effective and efficient way to reduce harmful diesel emissions from heavy-duty commercial trucks.
Some like it hot and cold
Especially the new PowerlinePLUS-Converters. They provide 20 to 50 watts and have been designed for applications with a temperature range of -55°C and 100°C. Converters with theses specifications are focussed to railway applications, aerospace, traffic controls, wind energy and semi military environments. They are however also ideal for industrial applications, in which heat generation has to be reduced.
