A SYSTEM FOR IMPROVING FUEL ECONOMY OF A MOTOR VEHICLE DURING DECELERATION

摘要

The present disclosure envisages a lean burn combustion inducer system for an internal combustion gasoline engine of a vehicle. The system comprises an injection circuit. The injection circuit includes an air filter configured to provide filtered air to an intake port of the engine via an intake manifold. The system further comprises a float valve that is in fluid communication with the air filer via a first connecting pipe, and that is in fluid communication with the intake port via a second connecting pipe. The float valve is configured to restrict an air flow from the air filter to the intake port when the vehicle is accelerating and allow the air flow from the air filter to the intake port when the vehicle is decelerating.
