Delphi Multec® High Value and Mid-Function Engine Management Systems are cost-effective families of systems that provide a complete, 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 Multec High Value Engine Management Systems — provide vehicle manufacturers with a base system of features necessary for most engine applications.
- Delphi Multec Mid-Function Engine Management Systems — with their additional content can help a manufacturer meet higher objectives for fuel economy, engine performance, and emissions. They can also support flexible fuel applications, including ethanol and compressed natural gas, which are important considerations for many markets.
Delphi Multec High Value and Mid-Function Engine Management Systems are designed to support vehicle manufacturers in markets that are now adopting Euro III, IV and V emissions standards. They can also help manufacturers meet more stringent emissions standards ranging up to U.S. LEV.
Benefits
- System components are optimized to provide the vehicle manufacturer with the required performance objectives within a cost-effective, complete package.
- Delphi can calibrate the manufacturer's software or create software for the manufacturer.
- Delphi provides a single point of contact for the program so it is easy for the manufacturer to manage and execute.
- Delphi's experienced and knowledgeable local teams with systems development, calibration, and validation capabilities, can provide fast response and fast time-to-market. A complete engine management system can, in many cases, be delivered in less than 12 months.
- Scalable systems allow the manufacturer to use the same base engine and system to meet multiple local and export market requirements, including Europe and North America.
Typical Applications
Delphi Multec High Value and Mid-Function Engine Management Systems are designed for vehicles with 3- and 4-cylinder multi port fuel injection (MPFI) gasoline engines. Delphi Multec Mid-Function Engine Management Systems with a Delphi Multi-Fuel System can also support alternate fuel requirements, such as ethanol and compressed natural gas.
Performance Advantages
Delphi Multec High Value and Mid-Function Engine Management Systems provide an easy and convenient way to implement a complete system. 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 system and our full range of major component development capabilities contribute to superior component design and cost-effective systems.
