  • Patent number: 10208599
    Abstract: The present invention relates to a heat engine having shafts with gears, position gears and a plurality of actuators. Energy is harnessed from the first shaft as it rotates. The second shaft can be coupled to the first shaft to transfer energy from the second shaft to the first shaft. One coupler is a chain. Position gears orient the chain wherein the rotation of the second shaft is inverted upon the first shaft so that the first shaft has a constant rotational orientation. Each actuator is preferably a double acting actuator that can supply force to both push and pull upon a belt connected to the actuator rod. A 1-way clutch and gear connects the belt to each shaft wherein the belt (driven by actuator) imparts a positive force upon the first shaft on the out stroke and a positive force upon the second shaft on the return stroke.

  • Patent number: 10184390
    Abstract: A method of operating an automotive system having an internal combustion engine equipped with an electric compressor and a turbocharger having a turbocharger compressor is disclosed. A surge threshold line and a pre-surge threshold line in a turbocharger compressor map are defined as a function of a turbocharger compressor pressure ratio and mass flow rate. The pre-surge threshold line is defined in terms of greater mass flow values for each corresponding pressure ratio value of the surge threshold line. The position of a turbocharger compressor working point in the turbocharger compressor map is monitored as a function of the turbocharger compressor pressure ratio and mass flow rate. When an increased torque request is detected, the electric compressor is activated to assist the turbocharger compressor in delivering the requested torque when the turbocharger compressor working point crosses the pre-surge threshold line in a direction towards the surge threshold line.
