摘要： A four-stroke engine (1) structured to introduce fresh air and EGR gas into a cylinder (1a) includes a blowdown supercharging system (40) using a combustion chamber internal pressure when exhaust valves open in an expansion stroke of a first cylinder (hereinafter denoted as an exhaust blowdown pressure) for introducing EGR gas into a second cylinder from near a bottom dead center of an intake stroke to near a bottom dead center of a compression stroke of the second cylinder which is different from the first cylinder in combustion timing, and a secondary air supply system (20) supplying secondary air to an exhaust port (1e) of the second cylinder prior to arrival of the exhaust blowdown pressure at the second cylinder. The secondary air in the exhaust port and the EGR gas are supercharged into the second cylinder by the exhaust blowdown pressure from the first cylinder.

摘要： A valve drive device for an engine include a valve for opening or closing an opening of a port to a combustion chamber, a valve drive member for opening or closing the valve and a drive shaft for driving the valve drive member. The device also includes a variable valve timing mechanism for continuously changing a working angle of the valve corresponding to an operation state of the engine by changing a state of drive force transmission from the drive shaft to the valve drive member. A variable valve clearance mechanism is configured such that a valve clearance that is defined as a gap between the valve and the valve drive member can be set at a first value during a first condition in which the working angle of the valve is large to a second different value during a second condition in which the working angle of the valve is small.

摘要： A metal gasket capable of preventing the occurrence of cracks in a stopper while employing a wave-shaped stopper, improving the contact pressure balance around the bead to enhance the engine performance, and improving the durability of the stopper. The metal gasket is constituted by a gasket component sheet having an opening formed to face a combustion chamber, and the gasket component sheet is provided with a combustion chamber bead surrounding the opening. An inner circumference side stopper lower than the height of the combustion chamber bead is formed along the combustion chamber bead in a portion between the combustion chamber bead and the opening such that at least a section of each wave where stress amplitude is large becomes thin, a thin portion and a thick portion are arranged alternately in each wave, and the hardness of the thin portion is higher than that of the thick portion.

摘要： A rotational cam can be disposed on a camshaft rotationally driven by a crankshaft of an internal combustion engine. A swing cam can be swingable through the rotational cam. The swing cam has a rotational cam abutment portion which contacts the rotational cam and transmits driving force from the rotational cam to the swing cam. An abutment portion displacing mechanism can be provided for displacing the rotational cam abutment portion to change a relative distance between the rotational cam abutment portion and a center axis of the swing shaft. Changing the relative distance allows changing a lift and the like of a valve.
