摘要： An improved throttle valve assembly of the type which includes a throttle body provided with a throttle lever and a second, intermediate lever interconnected with each other by a roller/cam slot mechanism, said throttle lever being adapted to be moved by said second lever which is connected through the throttle linkage to the accelerator. The improvement comprises means disposed between the throttle lever and the second lever for adjusting the clearance existing between the cam slot and roller when the throttle valve is located in the vicinity of the idle position thereof, so that the excessive play that would otherwise arise at the accelerator when the throttle valve is in the idle position is reduced or avoided.

摘要： An air-fuel ratio control device of an internal combustion engine having a carburetor. An air bleed passage is connected to a fuel outflow passage of the carburetor, and an electromagnetic control valve is arranged in the air bleed passage. The control valve is controlled by the detecting signal of an oxygen concentration detector arranged in the exhaust passage so that the air-fuel ratio of a mixture fed into the cylinder of an engine becomes equal to the stoichiometric air-fuel ratio. When the vehicle is decelerated, the mean value of the potential level, which has been applied to the electromagnetic control valve before deceleration, is stored. When the throttle valve is opened during the deceleration and, then, the oxygen concentration detector detects that a rich air-fuel mixture is fed into the cylinder of the engine, the above-mentioned mean value is instantaneously applied to the electromagnetic control valve.

摘要： Disclosed is an internal combustion engine comprising a main combustion chamber and an auxiliary combustion chamber interconnected by two connecting passages with each other. A raised portion having a flat lower end face is formed on the inner wall of the cylinder head. A squish area is formed between the flat lower end face of the raised portion and the flat top surface of the piston when the piston reaches the top dead center. The spark gap of the spark plug is located in a first one of the connecting passages or in the auxiliary combustion chamber at a position near the first connecting passage. The first connecting passage is so arranged that the squish flow passes through in front of the opening of the first connecting passage for decelerating the combustible mixture stream forced into the auxiliary combustion chamber via the first connecting passage at the time of the compression stroke. The second connecting passage is arranged at a position wherein the squish flow does not obstruct the combustible mixture stream forced into the auxiliary combustion chamber via the second connecting passage at the time of the compression stroke.

摘要： Disclosed is an internal combustion engine comprising a main combustion chamber, a first auxiliary combustion chamber and a second auxiliary combustion chamber. The first auxiliary combustion chamber is connected to the main combustion chamber via a first connecting passage in which the spark plug is located. The second auxiliary combustion chamber having no spark plug is connected to the main combustion chamber via a second connecting passage. A flame of the combustible mixture contained in the first connecting passage and ignited by the spark plug reaches the second connecting passage and causes the ignition of the combustible mixture in the second auxiliary combustion chamber. As a result a burning jet is injected from the second connecting passage into the main combustion chamber a little while after the burning jet is injected from the first connecting passage into the main combustion chamber.

摘要： An internal combustion engine of a lean air-fuel mixture combustion type comprising a valve guide and an intake valve supported by the valve guide. A pumping chamber is formed between the inner wall of the valve guide and the outer wall of the valve stem of the intake valve. The valve head has on its outer wall an injection nozzle connected to the pumping chamber. When the intake valve returns to its closing position at the time of the intake stroke, a fuel is injected from the injection nozzle into the combustion chamber filled with a lean air-fuel mixture whereby, a rich air-fuel mixture layer is formed in an ignition area around the spark gap of the spark plug.DESCRIPTION OF THE INVENTIONThe present invention relates to an internal combustion engine of a lean air-fuel mixture combustion type, and particularly relates to an internal combustion engine of a lean air-fuel mixture combustion type in which a mixture in a combustion chamber is formed by two separate mixture layers comprising a lean air-fuel mixture layer and a rich air-fuel mixture layer, whereby the rich air-fuel mixture is ignited by a spark plug.As a conventional method for simultaneously reducing the level of harmful components contained in exhaust gases from internal combustion engine, such as CO (carbon monoxide), HC (unburned hydrocarbons) and NO.sub.x (nitrogen oxides), there is known an effective method in which a lean air-fuel mixture having an increased air-fuel ratio (i.e., beyond the stoichiometric ratio) is used. This lean air-fuel mixture, however, is less easily ignited. In order to eliminate this disadvantage, an internal combustion engine has been proposed, in which a mixture in a combustion chamber is formed by two separate mixture layers comprising a lean air-fuel mixture layer and a rich air-fuel mixture layer, whereby the rich air-fuel mixture is ignited by a spark plug, thereby greatly improving the ease of the ignition and also reducing the level of harmful components in the exhaust gas. In order to form a rich air-fuel mixture layer in a combustion chamber, for example, there is known an internal combustion engine provided with fuel injection nozzles, in which a fuel is injected from the fuel injection nozzles directly to the combustion chamber, thereby forming a rich air-fuel mixture layer in the combustion chamber. However, an internal combustion engine of this type requires the provisions of expensive injection nozzles having durability to high temperature and high pressure, a complicated piping, and a plunger unit actuated precisely in synchronization with the revolution of the crankshaft of the engine. Consequently, an internal combustion engine of this type has a considerably more complicated construction.An object of the present invention is to eliminate the above-mentioned drawback. That is to say, an object of the present invention is to provide an internal combustion engine in which a rich air-fuel mixture layer can be formed in the combustion chamber by using an extremely simple mechanism.According to the present invention, an internal combustion engine comprises a cylinder block, a piston reciprocally movable in the cylinder block, a cylinder head fixed onto the cylinder block, a combustion chamber formed between the inner surface of the cylinder head and the top surface of the piston, a valve guide fixed to the cylinder head, an intake valve supported by the valve guide and comprising a valve stem and a valve head having on its outer wall an injection nozzle, an intake passage one end of which is connected to the combustion chamber via the intake valve, the other end of the intake passage being connected to the atmosphere, a fuel supply means for feeding a lean air-fuel mixture into the intake passage, a spark plug having gap located in the combustion chamber, a pumping chamber formed between the valve stem and the valve guide, the pumping operation of said pumping chamber being caused by the reciprocal movement of the intake valve, a fuel injection passage formed in the intake valve and arranged so as to connect the pumping chamber with the injection nozzle, a first check valve disposed in said fuel injection passage and only allowing outflow of a liquid fuel from the pumping chamber to the injection nozzle, a fuel supply passage arranged so as to connect the pumping chamber with a fuel source, a second check valve disposed in the fuel supply passage and only allowing inflow of the liquid fuel from the fuel source to the pumping chamber, said injection nozzle being arranged so as to be directed to an ignition area around the saprk gap, a fuel being injected from the injection nozzle into the combustion so as to form a rich air-fuel mixture layer in the ignition area when the intake valve returns to its closing position at the time of the intake stroke of the engine.The above-mentioned object of the present invention may be more fully understood from the following descriptions of a preferred embodiment of the invention, together with the accompanying drawings.
