Abstract: An engine/generator set, especially for use in driving a hybrid motor vehicle, in which an internal combustion engine is equipped with free flying pistons. The internal combustion engine operates in a two-stroke cycle with asymmetrical electrically controlled gas exchange with an exhaust gas turbine driving a turbocompressor. The power excess is fed back via a synchronous alternating current machine to the generator so that the vehicle is driven with high efficiency with an apparatus of reduced volume and weight per unit output.

Abstract: A novel turbocharger is disclosed that includes a compressor wheel and two turbine wheels all mounted on a common drive shaft. Also included is an auxiliary airflow generator to turn one or both turbine wheels. In normal operation, engine exhaust is used to drive the compressor wheel. The improved turbocharger uses two turbine wheels to drive one compressor wheel on one common drive shaft, which invention is intended to eliminate the turbo lag problem inherent in a single turbine turbocharger. In one embodiment, the auxiliary airflow generator spins the turbine wheel at low engine speeds to overcome the problem of turbo lag. In one embodiment, the airflow generator is a blower fan, which directs air through the turbine. In another embodiment, the airflow generator is a vacuum generator, which impels air through the turbine wheel. The two embodiments may be combined such that the blower and the vacuum generator compliment each other in operation.

Abstract: An autoignition two-stroke internal combustion engine utilizes rectangular working chambers and pistons with bar-type seals and rotary sleeve valves which connect the working chambers to exhaust gas turbines for secondary expansion and a supercharger. The supercharger is thermally decoupled from the expansion turbines but the expansion turbines are connected to the supercharger and the crankshaft by a planetary gear transmission which can be cut in or out by a disk-type brake or clutch.

Abstract: A power supply system for supplying electric energy to a rotary electric machine coupled to a rotatable shaft of a turbocharger for supercharging an engine includes a battery for supplying electric energy to the rotary electric machine, and a capacitor connected parallel to the battery through a switching control device. The capacitor is charged with electric energy from the battery at all times. When the engine needs to be revved up for quick acceleration, the switching control device is energized to supply electric energy stored in the capacitor, together with the electric power from the battery, to the rotary electric machine. Since the capacitor has a smaller internal resistance as compared with the battery, the capacitor can supply a large current to the rotary electric machine immediately after the accelerator pedal is deeply depressed for quick acceleration.

The compound motor has a clutch means to declutch the compressor from the turbine and to disable the turbine from transferring power to a gear set. The gear set is capable of simultaneously receiving power from the engine and the turbine and transferring this power to a final output shaft. The clutch mechanism brake or debrakes, and clutches or declutches, in response to torque or rotational force exerted on the turbine by the exhaust gas from the engine.

Abstract: A variable-cycle engine operates in a two-cycle mode when the rotational speed of the engine is lower than a predetermined speed and in a four-cycle mode when the rotational speed of the engine is higher than the predetermined speed. The engine has a first intake port and an exhaust port which are defined in an upper portion of a cylinder, and a second intake port defined in a lower side portion of the cylinder. When the rotational speed of the engine is lower than the predetermined speed, the engine operates as a two-cycle engine with the second intake valve and the exhaust valve in operation. When the rotational speed of the engine is higher than the predetermined speed, the engine operates as a four-cycle engine with the first intake port and the exhaust port in operation.
