Patent
·
OSTI ID:5371587
A digital electronic controller is disclosed for an engine equipped with an oxygen detector located along the exhaust path of the gases and a carburettor equipped with electrovalves for regulating the fuel flow rate. This controller comprises digital circuits for closed loop and open loop regulation including a digital memory in which the carburettor regulation value is permanently stored, a logic circuit for controlling the operating modes and a plurality of amplifiers for controlling the electrovalves of the carburettor. This controller makes it possible to reduce the pollution level of motor vehicles.
