摘要： A positive crankcase ventilation gas diversion and reclamation system comprises a positive crankcase ventilation gas diversion line to divert oil laden positive crankcase ventilation gases from the air intake manifold of an internal combustion engine. A positive crankcase ventilation gas diversion line directs oil laden positive crankcase ventilation gases into a vapor headspace of a fuel tank. A pressure sensor measures a vapor pressure in a vapor headspace of a fuel tank, and a fuel tank vent valve is operative with a fuel tank vent line. A controller actuates the fuel tank vent valve into an open position and discharges fuel enriched vapor to the air intake manifold of the internal combustion engine. A method permits diverting positive crankcase ventilation gasses from the air intake manifold of an engine, and reclaiming oil laden fuel components and/or particulates from positive crankcase ventilation gasses.

摘要： To provide a mechanism for coordinating the operation of throttle valves in a carburetor system in which a plurality of carburetors are connected in series and are then arranged in parallel with one another so as to position shafts thereof in parallel with one another. The throttle valves are rotated on said shafts to open or close passages of the carburetors. In the throttle valve operation coordinating mechanism, each of the carburetors connected in series shares one shaft which is received in bearings positioned at opposite ends thereof. A link extends between the shafts of the carburetors arranged in parallel and coordinates the operation of the shafts.

摘要： A fuel injection system for an internal combustion engine provides a uniform flow of gaseous and liquid fuel to each of the intake passages of the engine. A balance passage interconnects each of the intake manifolds to each other and balances the pressure within the intake passages. A pressure regulator regulates the fuel pressure at the fuel injector. A reference pressure chamber within the pressure regulator communicates with the balance passage and controls the fuel pressure based on the balanced pressure within intake passages. The balance passage also communicates with a vapor separator of the fuel supply system that separates liquid fuel from gaseous fuel. The balance passage promotes even distribution of the gaseous fuel to the intake passages. The fuel injection system also includes plenum chamber that acts a source of air for the engine. The plenum chamber includes an drain outlet that communicates with the balance passage for returning blown back fuel from the plenum chamber to the intake passages.

摘要： A pulse balancing system is provided for a multicylinder two-stroke cycle internal combustion engine in which each cylinder is provided with its own mechanism for supplying an air-fuel mixture thereto. The vacuum pulse balancing system of the invention comprises a plurality of passages interconnecting each cylinder with one of the air-fuel mixture supply devices associated with one of the other cylinders, and one-way check valves provided in the passages. With the vacuum pulse balancing system of the invention, a vacuum pulse created by the piston in one of the cylinders is transferred not only to the air-fuel mixture supply device associated therewith, but also to the air-fuel mixture supply device associated with one of the other cylinders. This alleviates back pressure which may otherwise be caused in the air-fuel mixture supply device associated with the other cylinder due to the on-again off-again suction of air-fuel mixture therefrom to its associated cylinder.

摘要： A carburetion system for V-type internal combustion engine having a first carburetor and a second carburetor disposed in a space between a first cylinder and a second cylinder arranged in a form like V and adapted to supply air-fuel mixture to respective cylinders independently, improved to have a compact structure and superior intake charging efficiency with capability of substantially uniformly supplying the mixture during acceleration and deceleration of the vehicle. The carburetors have intake barrels defining therein intake passages communicating with the associated cylinders. The intake barrels are disposed substantially at right angles to the axes of the associated cylinders and in the close proximity of each other in such a manner as to partially cross each other. A pair of float chambers are disposed between the intake barrels below the point of crossing of the intake barrels. A main fuel system and a slow fuel system for introducing the fuel from each float chamber have a main fuel pipe and a slow fuel pipe which extend into the portions of the float chamber below the fuel surface. The axes of the main fuel pipe and slow fuel pipe are inclined to the axis of the intake barrel. The slow fuel pipe is arranged such that its axis intersects the fuel surface at a point as close as possible to the center of the fuel surface. Each float chamber accommodates therein a float which cooperates with a float valve in maintaining a constant fuel surface level in the float chamber. The float is arranged in such a manner as to move in parallel with the axis of the slow fuel pipe in response to a change in the level of the fuel surface in the float chamber.
