Patent number: 9091201Abstract: 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.

Patent number: 6814064Abstract: 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.Type: GrantFiled: October 29, 2003Date of Patent: November 9, 2004Inventor: Kenneth W.

In one embodiment, the control mechanism (16) varies the air supply responsive to air pressure in the intake in order to both throttle the supercharger (12) as well as substantially eliminate undesirable surge conditions therein.Type: GrantFiled: January 26, 2004Date of Patent: September 7, 2004Assignee: Accessible Technologies, Inc.Inventors: Daniel W.

Patent number: 6782877Abstract: The invention is directed to a method and an arrangement for controlling a charger (2000, 1000) which make possible a reduction of the load on the on-board electrical system especially during run-up of the charger (2000, 1000). A drive signal is formed which drives the charger (2000, 10000 1000). In dependence upon a first operating state of the engine (1005) which directly precedes an increase of the driver command torque, the drive signal is so formed that the charger (2000, 1000) increases its rpm already during this first operating state.Type: GrantFiled: January 31, 2003Date of Patent: August 31, 2004Assignee: Robert Bosch GmbHInventors: Michael Nau, Michael Baeuerle, Carsten Reisinger, Guido Porten

Patent number: 6640543Abstract: A variable displacement engine is provided with a group of variably operated cylinders which are controllable to start and stop operation under predetermined operating conditions, and a group of invariable operated cylinders which are constantly in operation irrespective of the operating condition. The engine is operably connected to a variable displacement control system operable to deactivate the operation of the group of variably operated cylinders under predetermined operating conditions, such as idling, highway cruising speeds, and the like, so that the overall fuel efficiency of the engine is improved. In an aspect of the present invention, a turbocharger is provided. The turbocharger includes an inlet for receiving exhaust gas from the invariable operated cylinders and an outlet for supplying compressed air to the variable operated cylinders. In one embodiment, the engine is a reciprocating piston type engine, and in another embodiment, the engine is a rotary piston type engine.Type: GrantFiled: September 21, 2001Date of Patent: November 4, 2003Assignee: Western Washington UniversityInventor: Michael Ronald Seal

Patent number: 6450156Abstract: 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.Type: GrantFiled: March 12, 2001Date of Patent: September 17, 2002Inventor: Albert F.

Patent number: 6343473Abstract: 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.Type: GrantFiled: June 21, 1999Date of Patent: February 5, 2002Assignee: Kanesaka Technical Institute LtdInventor: Hiroshi Kanesaka
