Electronic Fuel Injection (EFI) refers to a technology of introducing pressurized fuel for purposes of combustion. A typical EFI system for single-cylinder, spark-ignited 2 and 3 wheelers consists primarily of an injector, a fuel pump, an ECU, a suite of sensors and a throttle body. EFI systems usually allow much tighter control of air-fuel ratio of the exhaust and thus can be used to substantially enhance the efficiency of operation of catalytic converters. A move to EFI (from carburetion) is considered necessary to meet future emission norms in countries seeing mass manufacture of 2 and 3 wheelers. In addition, EFI also promises to provide minor improvements in fuel consumption in comparison with the best performing carburettors in the market today.

SEDEMAC offers Electronic Control Units for 2 & 3 wheeler EFI systems. These ECUs also incorporate state-of-the-art control software routines for various emission, fuel consumption and performance demands. SEDEMAC's ECUs for EFI application also incorporate SEDEMAC's Smart Ignition technology for control of the ignition system providing OEMs the flexibility of achieving best-in-class fuel consumption.

SEDEMAC offers its ECUs to OEMs for standalone ECU application or for vehicles which have EFI implemented along with control technologies such as ISG, AMT etc. Such integration helps avoid duplication of electronic components and provides OEMs the flexibility to incorporate vehicle-level performance functionality, offered by different control-intensive technologies, seamlessly and without restrictions. Further, SEDEMAC's ECUs for EFI application are designed to support operation with a wide range of injectors, pumps and sensors seen in EFI systems thereby allowing OEMs the freedom to choose the right combination of hydraulic and other mechanical/sensing hardware.
