Publication number: 20090199789Abstract: The idea that I am seeking to patent is the process of manufacturing and storing pressurized air to be injected into the combustion chamber of an internal combustion engine for ignition of the fuel. Unlike a standard engine, that continuously compresses air during every engine cycle, this engine will only compress the air that it needs for combustion or other functions. This compressive optimization saves the energy that would have been used to compress air continuously, thus significantly improving fuel economy. This requires the use of a storage facility. When the storage facility is pressurized to a predetermined amount this engine will no longer compress air. As the air is used and the storage facility pressure decreases to a predetermined amount, the compression cylinders valves may be aligned to raise the air pressure in the storage facility back up to the predetermined amount.Type: ApplicationFiled: February 8, 2008Publication date: August 13, 2009Inventor: Danny Franklin Beard

Patent number: 7227272Abstract: A control apparatus such as an ECU, that controls the generator of a vehicle, measures the engine rotation speed and generator rotation speed while the engine is idling, and calculates and stores the ratio of the speed values. Thereafter when the vehicle is being driven and the current value of generator rotation speed is required, it is calculated based on the stored ratio value and the currently measured speed of the engine. The processing load on the ECU is thereby reduced, since generator rotation speed measurement processing is performed only in the idling condition.Type: GrantFiled: December 21, 2004Date of Patent: June 5, 2007Assignee: Denso CorporationInventors: Tadatoshi Asada, Fuyuki Maehara
