| The fuel and air supply system of the present invention provides fuel from a fuel pump at a first pressure upstream of a pressure reducer, fuel being provided directly to the fuel injector at a reduced pressure on the downstream side of the pressure reducer. A bypass line in communication with the fuel line upstream of the pressure reducer provides fuel to an air reservoir at the first pressure. The air reservoir lies in communication with a porous member(s) in the fuel injector in an air inlet to a fuel volume within the injector upstream of the pressure reducer. Upon flow of fuel into the air reservoir and closure of normally open fuel and air valves in the reservoir, air at the first pressure is supplied the porous member(s), creating a pressure differential across the member(s), causing air to flow through the porous member(s) to form air bubbles in the fuel volume for two-phase flow through the fuel injector orifice. The air flows for a predetermined time until the reservoir fills with fuel which precludes further air flow into the injector. Upon shutdown of the engine, the valves in the air reservoir open, draining the fuel from the air reservoir and enabling air at atmospheric pressure to enter the reservoir, returning the system for reuse upon engine startup. | ||||||

| A fuel injection system for an in-line multi-cylinder internal combustion engine that comprises a injector rail, a fuel supplying unit for delivering fuel to the injector rail and which includes a high pressure fuel pump, a pressure regulator and a vapor separator installed as a unit on the same side of the engine as the exhaust ports for the cylinders. The fuel injection system further comprises an air compressor for delivering air to the injector rail and which is installed as a unit with a generator on the side of the engine opposite the fuel supplying unit. The compressor is positioned above the generator which has a larger diameter than the compressor, and these two components are provided with a common drive shaft that is drivingly connected to the crankshaft of the engine for rotation. | ||||||

| Injector apparatus for direct injection of liquefied gas fuels, particularly LPG into internal combustion engines, includes a partially stabilized zirconia tube which incorporates a sliding spool therein for controlling a metering orifice of a nozzle. The spool has a tip which extends beyond the nozzle and into the inducted air steam of an engine. Expanding gas entering the air steam from a central gallery in the spool and via the nozzle cools the tip thereby causing heat to be transferred from the spool to the tip thereof. | ||||||

| A fuel system for an internal combustion spark ignition engine (27) is provided with a unit (14) for pre-mixing liquid fuel with a part of the total air charge, a spray nozzle (43 117) through which the mixed air/fuel is passed, a heat exchanger (48 102) for heating the mixed air/fuel issuing from the spray nozzle (43 117) to produce a gas and a conduit (49 118) for conveying the gas to the inlet manifold (31 103) of the engine (27) where it mixes with the remainder of the air charge. | ||||||

| Herein disclosed is a cooling system for use with an internal combustion engine which is operated on evaporable fuel supplied from a fuel tank. The cooling system comprises a tube extending from the fuel tank to a venturi throat portion of an air induction passage of the engine, an expansion valve connected to the tube and opening the tube when a pressure in the tube downstream of the valve is reduced to a certain degree, an evaporator device connected to the tube at a position downstream of the expansion valve, and a structure for defining an enclosed space about the evaporator device. | ||||||

| An electronic and mechanical fuel feeding system comprises a mechanical fuel induction system coupled with an electronic fuel injection system through a diverter valve in fluid communication with a mechancial pump. The diverter valve includes a valve actuator responsive to an electrical signal to couple the inlet of the diverter valve with the outlet of the valve connected in fluid communication with electronically controlled injector nozzles. Alternatively, absence of an electrical control signal at the valve actuator causes coupling of the inlet of the diverter valve to a second outlet coupled in fluid communication with a mechanical carburetion system. In the preferred embodiment, the electronic fuel injection system comprises a control circuit responsive to changes in engine speed, manifold pressure, exhaust gas temperature and cylinder temperature so that accurately metered amounts of fuel are delivered by the injector nozzles to the engine cylinders. Since the amount of fuel supplied to the injector nozzles by a mechanical pump may exceed the amount necessary to efficiently operate the engine, a fuel return line downstream of the injector nozzles returns excess fuel to the fuel tank through a restricted orifice to prevent excess depletion of fuel at the injector nozzles. | ||||||

| A fuel system for a mixture-compressing, spark-ignited four cycle internal combustion engine with charge stratification of the type wherein a major portion of the charge is introduced into a main combustion chamber as a lean fuel-air mixture by a main mixture forming system such as a carburetor and wherein the remainder of the charge is introduced into an auxiliary combustion chamber joined to the main combustion chamber via a firing channel by an auxiliary combustion chamber injection pump and injection nozzle is improved by the provision of only a single fuel feed pump which is connected to the fuel tank and supplies fuel from the tank directly to the injection pump at a first pressure and supplies fuel to the main mixture forming system via a pressure reducing valve at a second pressure that is lower than the first pressure. According to a preferred embodiment, the single fuel feed pump supplies fuel to the injection pump at a pressure of 1 bar and the pressure-reducing valve is a pilot valve that reduces the pressure of fuel supplied to it to 0.2 bar. | ||||||

| Apparatus for injecting fuel into the intake pipes of an internal combustion engine. The apparatus has an air channel branching off from the intake line at a point ahead of an adjustable throttle flap; a fuel metering device supplying fuel to the air channel in dependence upon engine load; and a fuel delivery pump arranged to receive a fuel-air mixture from the air channel through a narrowed constriction. The fuel pump passes the fuel-air mixture, with additional air which may be supplied thereto, to a fuel distributor which directs the mixture to the individual intake pipes of the engine. | ||||||
