In the two - stroke engine, Fig. 1, on the downstroke of the piston, the plunger P draws in air from the atmosphere through the valve L and fuel through the adjusting valve L<3> and the suction valve L<1> on the end of the air valve spindle. On the upward stroke the air is rapidly compressed with the fuel, thus heating it and mixing with it, until, at the end of the stroke, the piston opens the double-seated valves M and the fuel is injected into air compressed in the cylinder. The explosion causes the valves M to seat upwards. In a modification, the pump plunger is driven from the crank-shaft if applied to a two-stroke engine or from a half-time shaft for the four-stroke engine. The ...

MULTI-FUEL DELIVERY SYSTEM

A method for fuelling an internal combustion engine, and a fuel system for delivering a variety of fuel types to the engine, configured to accommodate liquid fuels such as gasoline, ethanol or a blend thereof, and gaseous fuels such as CNG, LNG or LPG. The engine is configured to operate on any of the designated liquid fuels, and can switch between the liquid and gaseous fuels. The fuel system includes a common delivery arrangement, for selectively delivering fuel into the combustion chamber of each cylinder of the engine, comprising a fluid delivery injector and a liquid metering device configured for operation in concert. The same common fluid delivery injector is used for delivery of gaseous fuel only, delivery of liquid fuel only (by way of an air assist delivery process), or delivery of a fuel mixture comprising the gaseous fuel and the liquid fuel.

Fuel injection method and apparatus

Method and apparatus for fuel injection to an internal combustion engine is disclosed. Gas is supplied to a fuel holding chamber to maintain a reference pressure which is above atmospheric pressure in the fuel holding chamber. A metered quantity of fuel is delivered into the holding chamber against the reference pressure. Communication is established between the holding chamber and the engine, and the supply of gas to the holding chamber is maintained while the communication exists so the pressure of the gas is sufficient to displace the metered quantity of fuel from the holding chamber to the engine.

Fuel injection device for model engine

A fuel injection device for a model engine capable of injecting fuel directly into a combustion chamber of the engine, to thereby insure stable feeding of fuel even under severe operational conditions. A check valve is arranged in a fuel injection passage or port to prevent backflow of fuel. Such construction permits the fuel injection device to be mounted directly on a cylinder of the engine to inject fuel directly into a combustion chamber of the engine, unlike the prior art. Also, in the present invention, pressurized air held in an air holding space may be injected together with fuel only during fuel injection, resulting in fuel being injected in the form of a fine mist-like shape.

For the injection of premixed fuel and air into a diesel engine cylinder, a nozzle assembly has a piston reciprocably mounted in a nozzle body to define a premixing chamber therein. Fuel and air are delivered into this premixing chamber through respective ports which are simultaneously covered and uncovered by the piston. Extending through the premixing chamber, a stepped plunger has one end slidably fitted in a bore in the piston to define a pressure chamber therein for exerting a decreasing air pressure on the plunger and has the other end arranged for movement out of and back into the nozzle body for spraying the fuel-air mixture from the premixing chamber through spray holes formed therein. During the stroke of the piston to compress the fuel-air mixture trapped in the premixing chamber, the compressed mixture acts on the step of the plunger to hold same retracted in the nozzle body against the decreasing air pressure in the pressure chamber. Only upon movement of the piston into positive ...

Injecting means for internal combustion motors or for diesel engines

Fuel injection system

A dual fluid injection system which comprises a liquid fuel metering device, a fluid delivery device, and apparatus providing an interface therebetween. The interface conveys liquid fuel along a flow path from the metering device to a mixing zone for mixing with air from a pressurized supply to provide an air-fuel mixture for injection by the fluid delivery device into a combustion chamber of an internal combustion engine. The flow path may involve a directional change by way of a turn section. The flow path is sized such that liquid fuel is retained therein by virtue of capillary action, whereby a quantity of liquid fuel is retained after a delivery event such that the flow path remains substantially filled with liquid fuel in readiness for the next delivery event during operation of the engine.

Method of operation of motor vehicle internal combustion engine involves controlled mixing of exhaust gas and fresh charge stream with extra oxygen content

The method of operation of a separately ignited internal combustion engine has direct cylinder fuel injection controlled as to mixture. Exhaust gas is introduced into the cylinder to form a fuel base mixture with high exhaust gas content. Shortly before the ignition point, adjacent to the spark plug, a limited mixture of fuel and an oxygen bearing fresh gas stream is injected. At low speeds and loads a lean base mixture is formed and a richer mixture is produced at high speeds.

IMPROVEMENTS RELATING TO APPARATUS FOR DELIVERING FUEL TO INTERNAL COMBUSTION ENGINES

Internal combustion engine having a fuel injection system

The fuel injection system delivers both air and fuel directly into a combustion chamber (17). The system has a fuel pump (10,21,23-28) which comprises a piston (21) and solenoid (26) and which delivers a fixed amount of fuel in each operation. The fuel is delivered into air supplied from a source of pressurised air and the delivery of fuel and air is controlled by a solenoid operated poppet valve (15). A controller controls the quantity of fuel delivered by the pump in each engine operating cycle and also timing of delivery of fuel and air into the combustion chamber (17). In a modification, the poppet valve 15 is opened briefly when there is high gas pressure in the cylinder 17 and a volume of high pressure gas is trapped in a closed pressure storage vessel (30, fig.2) for use in atomizing the fuel in the next engine cycle. The fuel may be metered directly into the flowing high pressure air as it flows to the combustion chamber via a sonic nozzle (44, fig.3) or a pressure operated poppet ...

Regulating. - The Specification as open to inspection under Sect. 91 (3) (a) describes a method of controlling the amount of fuel injected into the cylinder without varying the pump delivery. A chamber h, Fig. 6 (Cancelled), is provided in the upper part of the fuel injector, to which surplus fuel delivered by the pump may leak from the chamber e<4> past the stem of the spraying-valve f. This leakage is led past the non- turn valve h<6> to a collecting-pipe common to all the cylinders and provided with an adjustable spring-loaded discharge valve, by means of which the pressure in the collecting-pipe, and hence the leakage between the chambers e<4>, h, may be regulated.
