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： 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： Un moteur orbital possède des ailettes (70) maintenues par l'enceinte du moteur et un organe de piston (40) effectuant un mouvement alternatif radial dans l'enceinte lorsque l'organe de piston (40) effectue un mouvement orbital. Des jambes d'ailette (72) s'étendant le long des faces d'extrémités (42) de l'organe de piston (40) coulissent par rapport à celui-ci dans une direction à angle droit par rapport au mouvement de va-et-vient de l'ailette (70). Un assemblage de joints montés dans chaque jambe d'ailette (72) possède un coussinet de joint (86) dirigé vers et agissant de concert avec un anneau de joint (60) logé dans une rainure dans la face d'extrémité (42) de l'organe de piston (40), et une partie de base (85) qui engage une face de la paroi d'extrémité de l'enceinte, de sorte que l'ailette (70) peut se déplacer dans la direction axiale de l'axe de l'organe de piston par rapport à l'assemblage de joint et indépendemment de celui-ci. Des ressorts sont prévus pour solliciter le coussinet de joint (86) radialement vers l'extérieur pour engager la face transversale (80a) de l'ailette (70) qui coulisse sur la périphérie extérieure de l'organe de piston (40) pour maintenir l'étanchéité entre le coin extérieur de l'organe de piston (40) et le coin intérieur de l'ailette (70) à la jonction entre la face transversale de l'ailette (80a) et la jambe d'ailette (72).
