    摘要： To simplify the assembling process to mount a valve operating mechanism on a cylinder head, one intake valve and one exhaust valve are mounted on the cylinder head symmetrically with respect to the axis of a cylinder shaft. A rocker arm supporting base which supports rocker arms is fixed to the top of the cylinder head. Rocker arm shafts are supported by the base. The central portions of the rocker arms engage with the rocker arm shafts in such a way that the arms are free to swing. Push rods and the intake and exhaust valves are engaged with the ends of the arms. The valve operating mechanism is enclosed in a head cover which is fixed to the top surface of the cylinder head. This engine is distinguished by having the mounting surface for the rocker arm supporting base, on which the rocker shafts are mounted, and the surface on which the head cover sits be virtually coplanar. This makes it possible to machine the two surfaces at the same time. In order to supply a sufficient quantity of lubricating oil to the entire valve operating mechanism, a particularly designed lubrication device is provided.

    摘要： A direct-injection diesel engine in which a shallow-dish type piston cavity is formed on a top surface of a piston; wherein in the vicinity of the top dead center, a squish area is defined mainly by the top surface of the piston and an inner surface of a cylinder head opposite the top surface; when a velocity of a reverse squish flow from the shallow-dish type piston cavity to the squish area, generated due to a movement of the piston and is represented by Vs, and a fuel spray velocity in the vicinity of a lip portion of the shallow-dish type piston cavity is represented by Vsp, the distance between opposite wall portions of the shallow-dish type piston cavity is set such that the ratio Vs/Vsp is not greater than 1.25; and the squish area constitutes a part of the combustion chamber.

    摘要： Disclosed is an internal combustion engine having a direct injection combustion chamber. The internal combustion engine includes a fuel injector mounted in a cylinder head at substantially a center of the combustion chamber; an intake port and an exhaust port formed in the cylinder head and which exit into the combustion chamber on opposite sides of the fuel injector; a first spark plug mounted in the cylinder head such that a firing tip thereof is positioned under where the intake port exits into the combustion chamber, the first spark plug operating to ignite a lean mixture of fuel and air supplied to the combustion chamber by the intake port and the fuel injector; a second spark plug mounted in the cylinder head on one side of the fuel injector, and which ignites a fuel-air mixture of a stoichiometric ratio fed into the combustion chamber by the injector and the intake port; and a piston head provided on a upper face of a piston. A cavity is formed in the piston head of the piston and encompassing an area on the piston head corresponding to a where the fuel injector is positioned. The cavity is formed to a predetermined depth and a predetermined size, to both sides of an imaginary line formed by connecting points on the piston head corresponding to where the second spark plug and the fuel injector are positioned, such that a swirl effect of the fuel-air mixture in the combustion chamber is better generated.
