Abstract
An engine system comprising: an exhaust gas system for removing exhaust gas from the engine; a turbocharger comprising a compressor for inducing air towards the engine and a turbine provided along the exhaust gas system and driven by removed exhaust gas for powering the compressor; a hydrogen delivery apparatus adapted to deliver hydrogen to the exhaust gas system such that the hydrogen can combust and expand, thereby increasing the speed of the turbine. The increased speed of the turbine operation decreases turbo lag and increases engine responsiveness.
Claims17
An engine system comprising:
- an exhaust system;
- a turbocharger comprising a compressor powered by a turbine within the exhaust system;
- and
- a hydrogen delivery apparatus with an inlet coupled to engine cylinders and an outlet coupled to the exhaust system, wherein the engine system is adapted to power a hybrid vehicle and the hydrogen delivery apparatus receives electrical energy generated during deceleration of the vehicle.
A method of operating an engine system with an exhaust system, comprising:
- turbo-charging an engine with a turbocharger that includes a compressor and a turbine;
- compressing air within the compressor, inducing air towards the engine, and powering the compressor with the turbine;
- driving the turbine using removed exhaust gas;
- delivering hydrogen to the exhaust gas upstream of the turbine;
- increasing a speed of turbine rotation by combusting hydrogen;
- generating hydrogen using a reformer device;
- and
- powering the reformer device using electrical energy generated during deceleration of a vehicle.
