Abstract: A gas/air mixer assembly provides a Venturi metering system that may draw fuel from a zero governor, mix it with air to form a homogenous gas/air mixture for delivery to an internal combustion engine. The gas/air mixer assembly may also accept fuel under pressure from a gas metering valve or fuel injector for delivery to an internal combustion engine. The mixer includes an air horn, the relative position of which in relation to a shaped restriction body governs the air flow into the engine intake manifold. The flange of the air horn is configured to redirect the flow of air without generating significant turbulence, and providing a maximum velocity perpendicular flow to the injection of fuel to be mixed therein. The relative position of the air horn to the shaped restriction body is determined based on the cubic capacity and speed of the engine with which it is used.

Abstract: The present invention provides a parallel vaporized fuel system as well as a fuel vaporization apparatus for an internal combustion engine. More specifically, when the parallel vaporized fuel system is applied to vehicles, vaporized fuel is provided for general driving and liquid fuel is supplied as needed for immediate and heavy acceleration. The liquid fuel is generally gasoline, methanol or ethanol wherein the fuel vaporizes at a temperature of 425° F. or less. Fuel is delivered to the engine using the liquid fuel system until an adequate amount of vaporized fuel can be produced for operation of the engine. As vaporized fuel is produced liquid fuel being delivered to the engine proportionately reduced. Thereafter liquid fuel can be supplied to the engine when needed to compensate for the delay in vaporizing liquid fuel. This system can thereby provide improved fuel economy and reduced emissions over vehicles operating entirely from liquid fuel.

Abstract: A multicylinder internal combustion engine with an exhaust-driven turbocompressor and with a divided exhaust gas flow has at least two exhaust valves (2,3) and one intake valve per cylinder. A first exhaust valve (2) is connected to a first exhaust manifold which leads to the turbine of the compressor, while a second exhaust valve (3) is connected to a second exhaust manifold which opens downstream of the turbine. The charging pressure in the engine can be regulated by virtue of the opening periods of the exhaust valves (2,3) being varied in relation to one another in order to adapt the flow through the exhaust turbine to a value which provides the desired charging pressure in the engine. By opening the second exhaust valve (3) increasingly earlier, an increasingly lower charging pressure can be achieved.
