  • Publication number: 20090041577
    Abstract: A turbine assembly for a variable-geometry turbocharger includes a turbine housing defining a divided volute having first and second scrolls, wherein the first scroll has a substantially smaller volume than the second scroll. The first scroll feeds exhaust gas to a first portion of a turbine wheel upstream of the throat of the wheel, while the second scroll feeds gas to a second portion of the wheel at least part of which is downstream of the throat. Flow from the second scroll is regulated by a sliding piston. The first scroll can be optimized for low-flow conditions such that the turbocharger can operate effectively like a small fixed-geometry turbocharger when the piston is closed. The turbine housing defines an inlet that is divided by a dividing wall into two portions respectively feeding gas to the two scrolls, a leading edge of the dividing wall being downstream of the inlet mouth.

  • Publication number: 20090007882
    Abstract: A compound cycle engine system has a rotary engine, which rotary engine generates exhaust gas. The system further has a compressor for increasing the pressure of inlet air to be supplied to the engine to a pressure in the range of from 3.0 to 5.0 atmospheres and an intercooler for providing the inlet air to the engine at a temperature in the range of from 150 to 250 degrees Fahrenheit. The system further has one or more turbines for extracting energy from the exhaust gas. The Miller Cycle is implemented in the rotary engine, enabling the compression ratio to be lower than the expansion ratio, allowing the overall cycle to be optimized for lowest weight and specific fuel consumption.

    Abstract: A variable geometry compressor having a housing, a compressor wheel and a plurality of vanes positioned between an exducer of the compressor wheel and a housing volute. The vanes are adjustable through a range of positions, but a vane actuation system is configured to actuate the vanes through three discrete positions from among the range of positions. The actuation system has an actuator that includes an actuator housing containing a diaphragm that divides a housing chamber into two portions. Through the application of a vacuum to either chamber portion, the diaphragm drives a rod to actuate the vanes between two of the discrete vane positions, while a spring returns the vanes to the third position when no vacuum is applied. The actuator is controlled by an open-loop controller.

    Abstract: A compact, solid mount unit supercharger control system is installed at the bottom front end of the engine, directly onto the crankshaft of a vehicle. An accessory drive belt around the accessory belt pulley of the system rotates continuously to keep vehicle accessories (alternator, water pump, etc.) operating. A second belt around a larger pulley drives the supercharger blower. A switch mounted with the vehicle dashboard controls engine generated electrical current to the system. In order to activate the supercharger, the switch is turned on. Electric current flows to the system and energizes an electromagnet, creating a magnetic field which compels engagement of the rotating accessory pulley with the supercharger pulley by means of a slide plate. The belt around the supercharger pulley then rotates, operating the supercharger. When activated, the supercharger forces air into the engine cylinders for greater horsepower output with fuel/air explosions within the cylinders.

  • Patent number: 6276138
    Abstract: A multi-cylinder Otto cycle internal combustion direct compound engine for motor vehicles with an exhaust-gas turbocharger providing direct turbo compounding upon the engine control module receiving a speed signal indicating that the vehicle is traveling in a predetermined cruise-speed mode. Upon receipt of the signal the module turns-off each fuel injector feeding a second group of the cylinders, while maintaining fuel injection to a first group of cylinders and fully opening the electronic intake-air induction throttle. As a result the unfired second group of cylinder pistons are driven solely by compressed inlet-air pressure during the time the vehicle travels at or above a predetermined light-load cruising-speed, while positive pumping work occurs in all the cylinders. The engine thus conserves fuel during light load cruising speed while maintaining low pollutant emissions.

  • Patent number: 5704210
    Abstract: A gas generation engine having improved fuel economy and performance comprises a gas generator in the form of a supercharged internal combustion engine coupled to an expander in the form of a gas turbine. The exhaust produced by the internal combustion engine is utilized to drive the turbine. The values for the supercharging pressure ratio and internal combustion engine exhaust back pressure are chosen such that increased thermal efficiency and power output can be simultaneously obtained. The value for the peak cylinder pressure is significantly higher than the typical value for existing diesel engines. The form of internal combustion engine may be a four-stroke cycle piston engine with intercooled supercharging, the internal combustion engine driving the supercharger as well as providing the turbine input.

  • Patent number: 5448982
    Abstract: An intake system includes a supercharger for use with a power train. The power train includes a transverse engine and a transmission disposed transversely behind the engine. The engine has first and second rows of cylinders. Cylinders in each row are intended not to be fired one after another. The first and second rows of cylinders are offset sideways relative to each other. The intake system has an individual downstream intake part, downstream from the supercharger supported by the power train, for each row of cylinders. The individual downstream intake port includes a branch intake passage, branching off downstream from the supercharger and supported by the power train, and an inter-cooler disposed in the branch intake passage. One of the inter-coolers is located on a front side of the engine, and another of the inter-coolers is located above the transmission.

  • Patent number: 5003942
    Abstract: A rotary valve provides incorporates one or more sets of blades or vanes within the tubular body member of the rotary valve, which vanes are independent of the rotary valve to enable them to be spun about the longitudinal axis of the tubular rotary valve at a significantly higher rate than the rotary valve itself. Thus, the normal rotation of the rotary valve (typically rotating at one-half crankshaft speed for a four-cycle engine) not only periodically aligns the ports of the valve with the ports of the cylinder head and enables intake/exhaust functions in the usual manner, but the internal spinning vanes (rotating at a much higher speed) provide additional thrust and, therefore, improved pressure, efficiency and flow characteristics to the gas flow.

  • Patent number: 4864825
    Abstract: A suction type turbo-supercharger (6) is driven by highly negative pressure suction air produced by a negative pressure generator (4) which accelerates the exhaust gas stream of an internal combustion engine (1), external air being drawn by the negative pressure into the suction turbine (61) of the turbo-supercharger (6) to rotate the supercharging turbine (62) coaxial and coupled with the suction turbine (61) to thereby supercharge the air fed into the combustion chamber of the engine. The air stream produced by the negative pressure drives the turbo-supercharger and may also be used to cool the engine, in which case the turbo-supercharger is driven by the air stream after cooling the engine.

    Abstract: The internal combustion engine performs the thermodynamic cycle partially inside the cylinder, with the piston connected to the crankshaft, and partially in a turbo blower in which there takes place the final stage of the expansion of the burnt gases and, simultaneously, the suction and the first phase of compression of the air. The said compression is completed afterwards in the cylinder, continuously and without any partialization.

  • Patent number: 4700542
    Abstract: An internal combustion engine apparatus and method of operation includes the monitoring of the exhaust gas temperature and air-fuel ratio on a continuing basis. The exhaust gas temperature is compared to a stored value and compression of the input air is varied to cause the exhaust gas temperature to equal the stored value. By minimizing the exhaust gas temperature increased engine efficiency can be realized. The invention may be embodied in a variety of engine configurations, including piston and turbine systems.
