Delphi High Value and Mid-Function Engine Management Systems (EMS) are cost-effective families of systems that provide a complete EMS in one, easy-to-manage package. They allow vehicle manufacturers to tailor content for a wide variety of engine programs—from the most cost-sensitive applications to those intended to achieve even higher levels of efficiency and performance. Delphi can provide all necessary algorithms and calibration services as well as the required components. Full on-board diagnostics are also available.
Delphi High Value and Mid-Function Engine Management Systems are designed to support vehicle manufacturers in markets that are now adopting Euro III and Euro IV emissions standards. They can also help manufacturers meet more stringent emissions standards ranging up to U.S. LEV.
Benefits
Typical Applications
Delphi High Value and Mid-Function Engine Management Systems are designed for vehicles with 4-cylinder gasoline engines. They are also suitable for 3-cylinder programs. The Delphi Mid-Function Engine Management System with Delphi Multi Fuel can also support alternate fuel requirements, such as ethanol and compressed natural gas.
Performance Advantages
Delphi High Value and Mid-Function Engine Management Systems are an easy and convenient way to implement a complete EMS. They offer features that can help vehicle manufacturers improve fuel economy and enhance engine performance, while meeting targeted emissions standards. Delphi's unique understanding of the complete EMS and its full range of major component development capabilities contribute to superior component design and cost-effective systems.
