摘要： An engine has separate cylinders to which rich and lean mixtures are respectively supplied. A common carburetor that is set to make a rich air-fuel mixture is used for feeding both rich and lean mixtures. An air-supply passage is connected to an intake manifold that communicates the carburetor with the cylinder to which lean mixture is fed. The air introduced from the air-supply passage is mixed with the rich mixture to produce the desired lean mixture. A valve unit is installed in the air-supply passage, so that the rich mixture is fed to all the cylinders during high-load operation by closing the valve.

摘要： An engine with a vertically oriented parallel valve and stem arrangement accommodating tumble flow to support spark-ignited fuel usage. The engine may be provided in a configuration generally suited for swirl flow, compression combustion fuel usage. However, the introduction of a unique, replaceable valve head assembly may be utilized to induce tumble flow within a combustion chamber of the engine. Thus, spark-ignited fuel may be utilized without requiring vast overhaul of the engine to accommodate such fuels. Notably, with the addition of such an assembly, diesel fuel may be replaced with natural gas on large scale equipment without the requirement of impractically burdensome or expensive measures.

摘要： An internal combustion engine according to the present invention includes a piston reciprocally movable within a cylinder for affording rotational motions to a crankshaft, a combustion chamber formed among the piston, the cylinder and a cylinder head, an intake valve mechanism for opening and closing an intake passage to be communicated with the combustion chamber, igniting means having its igniting portion facing the combustion chamber, fuel supply means for supplying a predetermined quantity of fuel toward a predetermined wall of the combustion chamber, which is heated to a predetermined high temperature by the combustion in the combustion chamber, and an exhaust valve mechanism for opening and closing an exhaust passage to be communicated with the combustion chamber. During the running operation, the fuel is brought by the fuel supply means into contact with the predetermined wall having the predetermined high temperature of the combustion chamber, which is evaporated from the surface of the wall, so that the gasification of the fuel is promoted to effect combustion with high efficiency and to prevent emission of unburned noxious contents such as hydrocarbons.

摘要： An automotive multicylinder internal combustion engine is liable to emit noxious gases under medium and low load conditions. Such air-polluting emissions as hydrocarbons, carbon monoxide and oxides of nitrogen are effectively reduced by supplying a rich mixture with air-fuel ratio of approximately 12 to 14 to a group of its cylinders, and a lean mixture with air-fuel ratio of approximately 17 to 20 to the remaining cylinders. While under high load conditions, substantially the same mixture with air-fuel ratio of approximately 13 to 15 is supplied to all the cylinders to prevent a drop in engine output and improve fuel economy.

摘要： An improved multi-cylinder internal combustion engine for producing cleaner exhaust gas. The engine has a novel fuel gas intake device in which a lean mixture gas having an air-to-fuel ratio of about 16-20 is fed almost uniformly to all the cylinders by means of a carburetor, and some of the cylinders are provided with a fuel addition passageway to supply an appropriate amount of additional fuel in accordance with various operation conditions of the engine in response to an opening angle and abrupt opening of a throttle valve of the carburetor so that a rich mixture gas having an air-to-fuel ratio of about 12-14 may be fed to such cylinders, whereby the amount of harmful gases, such as HC, CO and NO.sub.x in the exhaust, can be effectively reduced.
