Title: Kinetic energy utilization system for use with vehicles with internal combustion engine
IPC: B60T17/00
Filed: 1984-10-22
Abstract: An energy conserving system for use with vehicles with an internal combustion engine and friction brakes includes a first valve in the air/fuel feed to the engine, a second valve in the exhaust line, a tank for pressurized air, and conduits between the tank and the valves. Actuation of a control system enables a first sensor to determine whether the brakes are being applied which opens the second valve to divert exhaust to the tank. During startup, the compressed air with or without fuel is used to reciprocate the pistons for a limited period after which fuel/air mixture feed at atmospheric pressure is commenced for normal engine operation. During engine startup, the brake sensor is not activated and fuel supply to the engine is only cut while braking. However, fuel can be mixed with pressurized air from the pressure tank at any time depending upon accelerator position to make the engine work as a compressed air supplied engine or as a turbo combustion engine.
