摘要： In a two-stroke spark ignition engine, fuel is injected through the cylinder wall at a location opposite to and above the level of the exhaust port (120). The fuel is delivered in the form of a number of streams such as, for example, streams (60), (61), (62). One of the streams (60) is directed upwardly across the cylinder to deliver fuel towards the combustion chamber cavity (122). This stream (60) is arranged not to impinge on the spark plug (123) but is caused to create a fuel rich cloud within the cavity (122). Streams (62) are directed downwardly and outwardly from the injection location and an optional stream (61) may be directed across the cylinder towards the exhaust port side of the cylinder.

摘要： A method of operating an internal combustion engine to control "knock" therein, by injecting a metered quantity of fuel entrained in a gas directly into the engine combustion chamber and controlling the timing of injection of the fuel into the combustion chamber. The control of timing of injection being effected by setting the time of the end of the period of injection in relation to the engine cycle, and reducing the duration of the injection period in response to detection of "knock" in the engine above a predetermined level. The duration of injection is reduced in a stepwise manner one step each cycle until "knock" is eliminated or reduced below the predetermined level.

摘要： In a spark ignition engine, fuel is injected directly into the cylinder volume. In order to obtain improved levels of combustion efficiency and reduced emissions the position of the fuel cloud within the cylinder volume is varied with engine load by controlled variation of fuel injection pressure. In particular, there is disclosed a method and apparatus for injection of fuel by compressed air where the position of the fuel cloud within the cylinder volume is controlled by conjoint control of fuel and air injection pressure. The invention has particular application to two-stroke cycle engines.

摘要： A method of controlling the operation of a solenoid, particularly for operating the fuel delivery valve of a fuel injector of an internal combustion engine. The method comprises controlling the rate of rise of the current in the solenoid (11) winding at a predetermined rate during at least the period between initiation of the current supply (10) and the commencement of movement of the solenoid armature. The said predetermined rate of rise of the current being preferably linear and being independent of the maximum rate attainable at the nominal voltage of the electrical source supplying the current. The rate of rise of the current is monitored (13) and the supply voltage is cyclically varied in response to said monitoring to maintain the predetermined rate of rise of the current. Also the cyclic variations of the current is monitored (22) to detect when the frequency of said cycles substantially change indicating the completion of the full extent of the movement of the solenoid (11) armature.

摘要： A fuel injection method and apparatus for in-cylinder injection in an internal combustion engine. Compressed air is used to inject the fuel through an injection nozzle (43) particularly shaped so that different fuel spray patterns are produced at high and low fuelling rates. At higher rates of fuelling corresponding to higher engine loads the fuel spray pattern is narrower and penetrates further into the cylinder volume whereas at lower rates of fuelling corresponding to lower engine loads the fuel spray pattern is wider, less penetrating and relatively more confined. By appropriate selection of nozzle shape the spatial distribution of the fuel spray droplets can be made to vary favourably over a range of engine loads.

摘要： A two-stroke internal combustion engine (5) having a transfer port (9) and an exhaust port (8) in a cylinder (6) which are opened and closed in a timed relationship by the reciprocating movement of a piston (7). The exhaust port (8) communicates with an exhaust passage that is tuned to provide a pressure pattern in the exhaust passage that will create at the exhaust port (8) a predetermined pressure pattern while the exhaust port (8) is open. Coolant is supplied to the exhaust passage at engine speeds below the tuned speed and regulated over a range of engine speeds to maintain the pressure pattern in the exhaust passage over that range of engine speeds.

摘要： A method and apparatus for metering fuel to an engine wherein a continuous supply of fuel is provided by a pump (14) to a fixed capacity chamber (11) and gas under pressure is admitted periodically to said chamber to maintain in the chamber a pressure not greater than the fuel pressure, so that fuel will flow into the chamber as long as there is a pressure differential between the gas in the chamber and the fuel supply. A delivery port (20) in said chamber is open for substantially the duration of the period that gas is admitted to the chamber so that the fuel in the chamber at the time of admission of gas thereto, and fuel entering the chamber during the period of admission of gas, is delivered from the delivery port (20) to the engine. The pressure differential between the fuel supply and the gas in the chamber is controlled in accordance with the fuel demand of the engine to control the quantity of fuel delivered each cycle to the engine. A preferred form of each of a fuel referencing regulator (34), a fuel pressure regulator (16) and a metering and injection unit (25) are also disclosed.
