Abstract:
An apparatus and method for improving vehicle performance by application of pneumatic boost to vehicle engines, including diesel engines having at least one turbocharger supplying air to the engine, in a manner which increases engine torque output while minimizing the potential for exceed various operating limits to the maximum practicable extent. The vehicle's pneumatic booster system controller implements strategies for shaping the rate of the air injection during a boost event, tailoring the air injection to obtain maximum engine torque output while respecting the operating limits, by controlling the timing, duration, quantity and/or injection pattern during a boost event to achieve a refined distribution of compressed air injection over the course of the boost event to provide desired engine torque output and fuel efficiency while minimizing the potential for exceeding a wide variety of operation limits, regulatory, engineering and passenger comfort limits.
Abstract:
The present invention provides a device 200 that is capable of increasing fuel economy and engine performance whilst reducing exhaust emissions. The device 200 includes a fixed orfice 224 in an air flow channel between ambient air and a coupling means 226. The size of the fixed orifice 224 is pre-selected for a given type and size of engine. The flow or volume of air provided by the fixed orifice 224 is directed into the plenum chamber or intake manifold of the engine, and preferably downstream of the engine's management system.
Abstract:
A booster container (1), an inlet nozzle (10A) for air entering the container (1) and an outlet nozzle (12V) for air leaving the container (1), a body of liquid (14) within the container body (1), the body of liquid (14) being disposed remotely from the inlet nozzle (10A) and the outlet nozzle (12V), a plurality of deflectors (11A-11D, 15A-15E) located within and attached to the container body, forming passages through which the air travels and at least one of the deflectors being partially immersed in the body of liquid (14). Air passes around the deflectors into the body of liquid (14) and is influenced by a vacuum from an intake manifold, wherein the air forms bubbles in the liquid and leaves the body of liquid (14) under vacuum and passes through the passages (12) formed between the deflectors and leaves the booster container (1) through the outlet nozzle (12V) connected to the intake manifold of an internal combustion engine.

The present invention relates to a system and method for saving on fuel consumption and reducing pollutant emissions for an internal combustion engine, including a system comprising a pressure-responsive air-supply regulating device including a perforated air inlet passage with an air filtering means, an air outlet, a pre-calibrated primary air passage comprising coarse-tuning and fine-tuning air-flow and air-volume regulating means fluidically communicating with each other and to said inlet passage and air outlet, a secondary air passage for augmenting the volume of airflow supply at engine's part-throttle conditions fluidically communicating with said primary air passage and said air outlet; and pre-calibrated accompanying connecting conduit means connecting said device to the engine's intake manifold through said air outlet; and methods of operating and installing said system to said engine; wherein all said elements fluidically communicate and interact with each other to provide the precise air-flow regulation and resistances for a timely delivery of the correct required air flow velocity and additional air volume to said intake manifold in response to the manifold vacuum pressure fluctuations, thus attaining and maintaining the running engine's effective air-fuel ratio range of about 15:1 to about 18:1 at all engine load conditions.
Abstract:
A method for preparation of the fuel-air mixture provides for feeding into the flow of the fuel-air mixture a flow of a gas medium in the form of separate jets. Each jet of the gas medium is directed tangentially to the imaginary circumference (5) oriented coaxially to the flow of the fuel-air mixture and having the diameter (d) equal, approximately, to 0.2-0.8 of the diameter (D) of the cross-section of the flow of the fuel-air mixture, and the flow from the gas jets is brought to the value of the coefficient ( alpha ) of excess oxidizer in the fuel-air mixture of, approximately, 0.9-1.0. A device for preparation of the fuel-air mixture comprises a casing (8) with a main opening (9) and an annular distribution chamber (10) which is connected to the casing through channels (11), is mounted coaxially to the main opening (9) and is connected to a gas medium source through a feeding channel (12). The axis (14) of each channel (11) is oriented tangentially to the imaginary circumference (5) oriented coaxially to the main opening (9) and having the diameter (d) equal, approximately, to 0.2-0.8 of the diameter (D) of the main opening (9). A consumption regulator (17) is mounted on the section (16) of a feeding channel (12), located in the casing (8).
Abstract:
A device which is located between a carburetor (12) and an engine intake manifold (14) of an internal combustion engine includes oppositely rotating impellers (52, 54) mounted on air bearings (120). The air-fuel mixture exiting the carburetor impinges on the impellers and drives those impellers. Fuel droplets in the mixture are broken up to form a mixture capable of almost total burnout.
