    摘要： An ignition-engine system for internal combustion engines having two-valves per cylinder (100) with a larger intake valve (103) and a smaller exhaust valve (104) in a longitudinal layout with a single camshaft (118) operating bucketed valve stems 103a and 104a that are vertical, with the valves making up essentially the roof of the combustion chamber and having a volume essentially under the intake valve of approximately 35% of the combustion chamber and a volume under the exhaust valve of approximately 65%, and two spark plugs per cylinder with plugs (102a) and (102b) located at the edge of two opposite squish-zones (105) of a compact combustion chamber, wherein the air-flow near TC is channeled between the two large squish-lands (101a) and (101b) wherein the cross-section of the channel is approximately constant of average width “W’, resulting in a relatively more compact combustion chamber having squish-lands take up approximately ⅓ of the projected bore area of the cylinder and the more compact channel to be approximately ⅔ of the bore area, wherein as the piston approaches ignition it provides an approximately orthogonal-to-the-main-flow (109) through the action of the squish walls which have a clearance of only about 0.06 inches with the piston at top center for improving knocking by moving the spark-flame kernel toward the hotter exhaust valve.

    摘要： An internal combustion engine that includes a cylinder block formed with a cylinder bore, a cylinder head operatively connected to the cylinder block; a piston slidably disposed in the cylinder bore to define a combustion chamber; an engine front side squish area and a rear side squish area where the engine front and rear side squish areas include narrow gaps formed between a cylinder head and the piston is disclosed. The engine front side squish area and the engine rear side squish area generate a squish flow in the combustion chamber in response to the piston moving within the cylinder bore. Engine front and rear side igniter plugs are also provided that each include a pair of electrodes placed adjacent the respective engine front and rear side squish areas so that squish flow may pass through an igniter gap defined between the pairs of electrodes of the front and rear side igniter plugs.

    摘要： An improved ignition-combustion system for internal combustion engines comprising a compact combustion chamber zone (4) in the engine cylinder head (6) mainly under the exhaust valve (8) and with large air-squish zones (124a, 124b) formed at the edge of the combustion zone which produce colliding squish flows (2, 2a, 3a, 3b) with high turbulence (3c) at the center of the combustion zone, with one or two spark plugs (12a/118, 12b/18a) located at the edge of the combustion zone within the high squish zones, resulting in a combined ignition and combustion system of colliding-flow-coupled-spark discharge (CFCSD), with the ignition employing high energy flow-resistant ignition sparks which move under the influence of the squish flow towards the central turbulence region as the piston nears engine top center, to produce rapid and complete burning of lean and high EGR mixtures for best engine efficiency and lowest emissions.

    摘要： An intake and exhaust system for use with internal combustion engines that uses two intake valves and one exhaust valve for each engine. The three valves are preferably circular and spaced around the cylinder centerline in said cylinder head. One or more spark plugs (or other suitable ignition devices) are provided in the head on the cylinder centerline and/or between pairs of adjacent valves. For best results, the ratio of total exhaust valve cross sectional area to total intake valve cross sectional area should be in the range of 45% to 65%. Three squish areas having a total area of at least about 12% of the bore cross-sectional area are preferably provided spaced around said combustion chamber periphery and extending between pairs of adjacent valves. At top dead center, the distance between the piston corresponding head squish pad areas is up to about 0.02 times the bore diameter. This invention provides a fast and uniform lean burn, permits use of a high compression ratio and lower octane unleaded gasoline and provides improved thermal efficiency. Other fuels and other fuel ignition systems also benefit, such as diesel engines.

    摘要： A diesel engine using impingement and diffusion is described. In this diesel engine, both low smoke production and reduction of thermal load of the piston, as well as lighter construction of the piston, are realized. The main combustion chamber is situated in a part of the inner wall of the cylinder head. An impinging surface is made at the inner wall of the main combustion chamber in a way that the fuel jet after impingement, is dispersed from the edge of the impinging surface into the area of the main combustion chamber close to the squish area.

    摘要： A method of operation of an internal combustion engine to minimize NOx emission in exhaust gas involves detection of load on the vehicle engine as either a low load or a high load. While a low load is detected unthrottled air and a quantity of fuel providing for lean combustion are mixed with injection of fuel adjacent top dead center in the compression stroke. While a high load condition is detected, throttled air and a quantity of fuel governed by sensed oxygen content of the exhaust gas are mixed in an approximate stoichiometric ratio with injection of the fuel much earlier than injection at low load, preferably during the intake stroke.

    摘要： A combustion chamber located in the piston of an internal combustion engine is divided by restrictions into two or more partial chambers. The ratio between the minimum distance in the restricted area and the maximum distance in concave areas of the wall of the combustion chamber, as measured from the axis of the combustion chamber, is greater than or equal to 0.2. To improve the turbulence in the combustion chamber the proposal is put forward that the ratio between the minimum distance in the restricted area and the radius of the piston be smaller than or equal to 0.5, the wall of the combustion chamber being convex in the restricted area, and that the ratio between the maximum distance and piston radius be greater than or equal to 0.7.
