  • Patent number: 9797321
    Abstract: An internal combustion engine includes a cylinder block that defines a cylinder and a cylinder head positioned relative to the cylinder block. A reciprocating piston is arranged inside the cylinder for compressing an air and fuel mixture at a geometric compression ratio of at least 10:1. A crankshaft is arranged in the cylinder block and rotated by the piston. An intake valve is operatively connected to the cylinder head and controls delivery of air to the cylinder for combustion therein. A mechanism provides late intake valve closing via constant peak lift of the intake valve over at least 5 degrees of crankshaft rotation. A multi-stage boosting system, having a turbocharger, a supercharger, and a continuously variable transmission for varying the supercharger's rotating speed, is regulated by a controller to selectively pressurize air being received from the ambient for delivery to the cylinder.

  • Patent number: 9091201
    Abstract: A “two-cycle” internal combustion engine has a single or multi-stage pre-cooled compression, which allows the temperature and pressure of intake air to the combustion cylinders to be tightly controlled, so that a much higher compression ratio and pre-ignition compression pressure can be achieved without approaching the auto-ignition threshold. Because this design can effectively regulate and set the maximum pre-ignition temperature of the fuel-air mixture, it can combust virtually any type of liquid hydrocarbon fuel without knocking. This “two-cycle” engine, due to its higher compression ratio, generates power equivalent to or greater than a four-cycle “CWPSC” engine in a smaller and lighter engine and at the same or higher efficiency.

An input shaft of the supercharger is mechanically coupled to and driven by a piston-driven crankshaft. A bypass valve is configured to selectively bypass at least a portion of the air from the turbocharger air outlet around the supercharger. Power and fuel consumption are optimized by operating the supercharger to dilute the fuel-air mixture to achieve an excess air factor ? above 1.0, and in some cases above the upper range (?=1.3) of normal stoichiometric operation. The engine can operate in a lean low temperature combustion mode (e.g., HCCI) with the supercharger operating, and in a stoichiometric spark ignition combustion mode with the supercharger bypassed.

  • Patent number: 6814064
    Abstract: An internal combustion engine using variable compression ratio and variable fuel supply to one of two combustion chambers is presented. Varying the compression ratio is accomplished by changing the volume of a single combustion chamber. This, in combination with lean burning, results in a highly efficient prime mover particularly at the low torque outputs needed in passenger car applications. The relationship of compression ratio and fuel feed is varied with engine speed. Burning occurs in two stages, and this results in a clean exhaust. The invention allows very efficient throttling of two-cycle engines to be realized. A concept for supplying air to a two-cycle engine at very good efficiencies is also presented. The combination of these techniques can result in an engine for automotive use that is half the weight of conventional units with a thermal efficiency of 40% or more at average engine output.

    Abstract: An air compressor for charging an internal combustion engine includes a compressor for blowing compressed air into the intake manifold of the engine and a gas powered turbine for driving the compressor. In a first embodiment, the exhaust from a small gas powered turbine is coupled to the driving turbine of a standard turbocharger. In a second embodiment, the drive shaft of a small gas powered turbine is coupled to the drive shaft of a standard supercharger. In a third embodiment, a compressor turbine having an air intake, a compressed air outlet, and a bleed air outlet is coupled to a small gas powered turbine such that the bleed air outlet supplies the combustor intake of the gas turbine. The gas powered turbine drives the compressor and receives compressed air from the compressor via the bleed outlet. The system provides a constant boost, does not use engine horsepower, is easy to install, and does not need to be coupled to a rotating shaft or the exhaust system of the engine.

  • Patent number: 6343473
    Abstract: In a hybrid supercharging engine comprising a turbo charger TC becoming a maximum capacity at a speed higher than a maximum torque rotating speed of an engine and a volume type supercharger SC provided in series to the TC, wherein a two step supercharging is performed while controlling the SC in such a manner as to keep a supply air amount constant without relation to an engine speed, it is possible not only to set a low BSFC but also to set twice or more BMEP of the TC supercharging engine. Further, since a supply air amount to an engine is increased by supercharging mainly by means of an SC at a time of a low speed so as to accelerate the TC, a turbo lag is prevented from generating and a performance at a time of a steady operation can be obtained even at a time of a rapid acceleration from a low speed.
