Electronic Fuel Injected Engine

The 1990 Subaru Justy was the last car sold in the United States to have a carburetor although EFI has been around since 1950s. An engine's air/fuel ratio, 14.7:1, must be accurately controlled under all operating conditions to achieve the desired engine performance, emissions, functionality, and fuel economy. Our EFI microprocessor in the JetPower Series meters fuel very accurately and precisely, and use closed loop fuel-injection quantity-control based on feedback from an oxygen sensor (O2 sensor) installed in the exhaust manifold. This enables fuel-injected engines to minimize fuel consumption, optimize performance and reduce emissions than comparable carbureted engines.

Our EFI controllers are designed mainly for residential and commercial standby power generators with four or more cylinders. The onboard microprocessor, firmware upgradeable, has been developed for automotive EFI application known as Engine Control Unit (ECU). It has passed nine stringent emission tests in Beijing, China.

The benefits of EFI engines :

• Higher performance
• Less pollution
• Low maintenance
• Longer engine life
• Better fuel economy
• Less moving parts
• No fuel/air mixture adjustments
• Smoother and more dependable engine response when loaded
