Abstract: The present invention is a fuel injection system for small engines in which the fuel injection system takes the place of traditional carburetors and provides the engine with air, fuel and spark control. The fuel injection system is comprised of an electronic control unit (ECU) coupled with a throttle body, which has an integrated fuel injector. The ECU controls the amount of air that enters a cylinder by controlling the throttle plate, and the ECU controls the amount of fuel entering the air flow by controlling the injector. This fuel injection system offers to smaller engines the many advantages of fuel injected engines over carbureted engines such as increased fuel economy, better cold starting capabilities, lower outputs of harmful emissions and lower engine operating temperatures.
