Abstract
An engine management system that maximizes the efficiency of internal combustion engines (gasoline or diesel) based on the performance demanded of the engine and the environmental conditions that the engine is operating in. The engine intake and cooling systems are arranged such that that the engine intake air temperature and pressure and coolant temperature are continuously optimized to provide reduced emissions on start-up and increased efficiency and performance in all environmental conditions.
Claims20
An engine management system comprising:
- a first radiator for providing coolant to an engine and for cooling the coolant returning from the engine utilizing air at ambient temperature;
- a compressor for compressing air received at ambient temperature and ambient pressure and for outputting the compressed air;
- a second radiator located between the first radiator and the engine for receiving compressed air from the compressor and the coolant from the first radiator and for supplying the coolant to the engine and for outputting the compressed air;
- and
- a variable expansion valve for receiving the compressed air output from the second radiator and for outputting the expanded air to the engine wherein a level of expansion or compression of the variable expansion valve is based on a required engine performance level.
An engine management system comprising:
- a first radiator for providing coolant to an engine and for cooling the coolant returning from the engine utilizing air at ambient temperature;
- a compressor for compressing air received at ambient temperature and ambient pressure and for outputting the compressed air;
- a second radiator located between the first radiator and the engine for receiving compressed air from the compressor and the coolant from the first radiator and for supplying the coolant to the engine and for outputting the compressed air;
- an expansion valve for receiving the compressed air output from the second radiator and for outputting an expanded air;
- and
- a plurality of flow paths for selectively directing air to the engine, wherein a selected one of the flow paths corresponds to a particular engine performance level.
A method of providing intake air to a vehicle engine, the method comprising the steps of:
- receiving air having an ambient temperature and ambient pressure by a compressor;
- compressing the received air wherein the compressed air has a first temperature and a first pressure;
- and
- selectively providing the compressed air via at least one of a plurality of flow paths to the engine, the flow path being determined by verifying an operating mode of the engine.
