Delphi Multec® Gasoline Direct Injection Engine Management Systems

Delphi Multec® Gasoline Direct Injection (GDi) Engine Management Systems (EMS) are a cost-effective, family of fuel systems that provide a complete, easy-to-manage package and allow vehicle manufacturers to tailor content to their individual needs. The systems provide features that can assist vehicle manufacturers in meeting consumer demands for improved power, torque and, especially, better fuel economy.

Delphi Multec GDi EMS systems offer features such as:

  • High pressure pump flow control with variable rail pressure capability
  • Low emissions cold starts
  • Low particulate emissions
  • Multi-pulse capability for precise spray formation and penetration control
  • Enhanced turbo scavenging for low end torque improvement
  • Active valve train components
  • Gasoline/electric hybrid capabilities to help vehicle manufacturers meet fuel economy and greenhouse gas requirements including U.S. Corporate Average Fuel Economy (CAFE) and European Automobile Manufacturers Association (ACEA) CO2 fleet average 

Delphi can provide all necessary algorithms, calibration services, as well as the required components and full on-board diagnostics.

Delphi's Multec GDi Engine Management Systems are designed to help vehicle manufacturers meet current and future vehicle emission standards around the world,  including: Euro 5 and Euro 6; and U.S. Environmental Protection Agency (EPA) and California Air Resources Board (CARB) standards such as Tier 2, LEV, ULEV II, and SULEV.

Benefits

  • System components are optimized to provide the vehicle manufacturer with the required performance objectives within a cost-effective, complete package
  • Delphi can provide calibration and software or create custom software for the manufacturer
  • Delphi provides a single point contact for the manufacturer to facilitate management and execution of the EMS program
  • Delphi's experienced and knowledgeable local EMS teams, with their systems development, calibration, and validation capabilities, can provide fast response and help achieve fast time-to-market
  • Scalable systems allow the manufacturer to use the same base engine and EMS to meet multiple local and export market requirements

Typical Applications

Delphi Multec Gasoline Direct Injection Engine Management Systems are designed to support most 4-, 6- and 8-cylinder gasoline direct injection engine programs, including spray stratified and homogeneous combustion systems. They can also support hybrid architecture and flexible fuel programs including E85, an important consideration for many markets.

Performance Advantages

Delphi's high performance solenoid injection technology for stratified injection provides a high performance system with a significant cost savings compared to competitor piezo systems. The choice of solenoid technology eliminates the need for an expensive high voltage power supply in the engine control unit (ECU).

With Delphi's Multec GDi Engine Management Systems, it is possible to utilize the same ECU, high pressure fuel pump, fuel rail and Multec® 20 injectors on both homogeneous combustion and spray stratified systems—with the upgrade accomplished by means of software and calibration only. This can significantly reduce the associated hardware verification and validation requirements.

Alternatively, the customer can choose the Delphi Multec 10 fuel injector for homogeneous combustion systems, upgrade to Multec 20 for spray stratified systems, but still use the same high pressure pump and ECU for both systems.
