摘要： An auxiliary fuel supply system is provided for a two cycle internal combustion engine (302). A first fuel line (350) supplies fuel from the fuel pump (338) to a solenoid (352) which is continuously cyclable between ON and OFF states during running of the engine, includig high speed operation where detonation may occur. Fuel then flows through a second fuel line (354) to a restriction orifice metering housing (356), and then to a plurality of third branch fuel lines (358, 384, 386, 388, 390 and 392) for delivery to respective cylinders. The restriction orifices provide a pressure drop from the second fuel line to the plurality of third fuel lines, to provide lower fuel pressure in the third fuel lines, to reduce the chance of leakage at the intake manifold (326), and also to reduce fuel pressure fluctuations in the third fuel lines otherwise due to cycling of the solenoid. Metering housing structure is disclosed. The solenoid is controlled by a variable duty cycle oscillator (408), which in turn is controlled by a fuel enrichment signal (84) output by an electronic control which is responsive to engine knock and/or temperature. Control circuitry is disclosed.

摘要： The invention relates to a method for forming a fuel-air mixture and to a fuel supply device for an internal combustion engine, having an intake manifold, into which an air intake tube with an aspirated air metering device disposed in it discharges and to which the intake tubes leading to individual combustion chambers are connected. A plurality of fuel injection valves are provided, each of which is assigned to one combustion chamber, and having a central fuel vaporizer to which fuel can be supplied by means of a fuel metering device. To form a fuel-air mixture, the fuel to be supplied to the engine is vaporized and the fuel vapor is supplied to the aspirated air. In order to lower pollutant emissions after starting during the warmup phase of the engine, vaporization of the fuel is done at relatively low temperatures, so that the fuel vapor produced essentially comprises only highly volatile fuel components. The fuel vapor produced by the fuel vaporizer in a vaporization region is supplied, downstream of the aspirated air metering device to the air aspirated by the combustion chambers in order to form a fuel-air mixture.

摘要： An engine startup fuel control system for use with an internal combustion engine of the type having a plurality of combustion chambers, an air intake passage fluidly connected to each combustion chamber and a source of fuel. The system includes a multipoint fuel injector associated with each combustion chamber in which the multipoint fuel injector has an inlet connected to the fuel source and an outlet fluidly connected to the intake air passageway adjacent its associated combustion chamber. A cold start fuel injector also has an inlet connected to the fuel source and an outlet connected through a cold start passageway with each combustion chamber. A processing circuit selectively activates the multipoint fuel injectors as well as the cold start fuel injector. The processing circuit determines the air/fuel mixture introduced by the cold start fuel injector into each combustion chamber during engine startup and then selectively activates the multipoint fuel injectors to achieve a predetermined air/fuel mixture in each combustion chamber during engine startup. The processing circuit also variably retards the ignition of the combustion charge within at least one of the combustion chambers to achieve faster heating of a catalytic converter. Furthermore, the cold start fuel injector is optionally activated in a plurality of spaced subpulses for each combustion charge provided to each combustion chamber.

摘要： Several embodiments of additional fuel supply systems for internal combustion engines that supply supplemental fuel in addition to the normal charge forming device to satisfy certain specific requirements such as cold starting and cold running. In each embodiment, a separate fuel pump is provided for the supplemental fuel discharge but it is contained within and operated by the same operator of the main fuel pump for supplying fuel to the main fuel discharge. In some embodiments, the fuel pump is downstream of the supplemental fuel control and in other embodiments it is upstream of it. In one embodiment, the fuel pump and the supplemental control are all formed in the same housing.

摘要： Internal combustion engines utilizing conventional carburetors have auxiliary devices such as a choke and accelerator pump which cause over-rich mixture and consequently affect the fuel consumption and exhaust gas emissions adversely. The present invention improves the performance of such engines whilst retaining the advantages of conventional carburetors.The invention provides a spark ignition carburetor equipped engine with an electromagnetic injection valve disposed in the induction manifold for the supply of additional fuel when required. Actuation means for the electromagnetic injection valve are preferably electronic devices which comprise a pulse generator and measured valve transmitter (sensors) for each of the engine operating parameters relevant to the injection of additional fuel, thus the timing and duration of opening of the injection valve is controlled precisely.
