Abstract
A micro-pulsation metering fuel injection system, comprising a throttle body and at least one injection unit. The throttle body is mounted in an inlet pipe of a cylinder of an internal combustion engine for controlling a quantity of flow of air into a combustion chamber. The injection units are mounted on the throttle body and have each a plurality of micropumps. The micropumps suck in fuel and inject tiny droplets of fuel into an air inlet inside the throttle body, so that the droplets of fuel mix with air in the throttle body, creating a mixture, which enters the combustion chamber of the cylinder. A control unit senses operating parameters of the engine and drives the injection units via a driver unit. This allows precisely to control the quantity of injected fuel and flexibly to control the distributing fuel spray, resulting in higher fuel efficiency and lore exhaust emission.
