Delphi showcases Multec EFI

Delphi's Powertrain Systems division has recently showcased their Multec Electronic Fuel Injection (EFI). By controlling the air, fuel and spark delivery in engines, Multec EFI improves one- and two-cylinder engines' performance and fuel economy while significantly reducing emissions. In addition, Multec EFI marks the first use of Delphi's new smaller, lighter Mini-Switching Oxygen Sensor.

Delphi Multec EFI provides manufacturers an easy and convenient way to implement an electronic fuel injection system for gasoline and flexible-fuel powered engines. Designed to help manufacturers meet exhaust and evaporative emissions requirements for one- and two-cylinder engines, the system also achieves targets for engine performance and fuel consumption. Delphi Multec EFI can reduce fuel consumption in motorcycles from 10 to 15 percent.

"With Delphi Multec EFI, motorcycle manufacturers around the world can look to Delphi for the most efficient electronic fuel injection system for virtually any demand," said Ran Wu, Delphi's Multec EFI product manager. "Stringent emission legislation is being enacted in all corners of the globe; Multec EFI is one way to achieve these emissions goals."

Delphi developed the system for motorcycle, all-terrain vehicle (ATV) and scooter manufacturers around the world. Additional applications can include:

• Lawn and garden equipment
• Generators
• Snowmobiles

With a "green" emphasis, Delphi's Multec EFI can include:

• Sensors -- Offering pressure, engine temperature, air temperature, and crank position sensors
• Fuel injectors -- Possess anti-plugging features and flex-fuel compatibility from E0 gasoline to E100 ethanol and any blend
• Oxygen sensors -- Enable flex fuel operation and allow closed-loop control for better emissions-control
• Engine control module (ECM) -- 16 bit configurations, with small package size and flexible mounting options
• Mechanical throttle body - Low-cost option with an idle speed control and sealed shaft
• Electronic throttle control (ETC) -- Enhanced responsiveness to load change with fewer components
• Fuel pump - Compact, in-tank or in-line pump designed with low current consumption for small engine applications
• Ignition coil - Features more reliable combustion versus magnetos, and enables electronic spark timing
• Evaporative emissions canisters -- Meeting evaporative emissions regulations

Delphi also showcased its Mini-Switching Oxygen Sensors which are up to 50 percent smaller and a third lighter than conventional oxygen sensors suitable for a wide range of applications where space is limited. In Multec EFI applications, the Mini-Switching Oxygen Sensor provides closed loop control of exhaust gases to help manufactures meet current and future exhaust emissions standards by providing more accurate engine control and better exhaust system diagnostics. The sensor also enables flexible fuel operation for a variety of applications. Smaller and lighter, the sensors still maintain a high-temperature capability allowing flexibility when locating the sensor. Additionally, a low wattage heater reduces current draw while improving cold start emissions.
