ABSTRACT:
A method and apparatus for improving efficiency and reducing emissions of a vehicle's multi-cylinder internal combustion engine. The engine runs at best BSFC by intermittently disabling cylinders for torque control. The engine runs as an air compressor for braking, and after braking, runs as an air motor driven by the stored compressed air. The air motor capability permits stopping all fuel flow when the accelerator is released at any engine speed. Variable engine valve control eliminates the conventional throttle and EGR valve, and is utilized for maximum thermodynamic efficiency during air operation. A camshaft retard is utilized to minimize the pressurized components and to prevent cooling the catalyst during air motor operation.
