摘要： It is configured such that plasma generated at a time of ignition should diffuse over an entire combustion chamber in a spark ignition type internal combustion engine in order to improve fuel efficiency. An ignition device for a spark ignition type internal combustion engine is provided including an ignition plug and a transmission antenna provided in the vicinity of the ignition plug and adapted to transmit an electromagnetic wave to a combustion chamber. The ignition device allows a spark discharge generated between a central electrode and a ground electrode of the ignition plug to react with an electric field created via the transmission antenna in the combustion chamber so as to generate plasma and ignite fuel air mixture. A receiving antenna is arranged on a combustion chamber-facing surface of at least one of an intake valve and an exhaust valve, and is adapted to receive the electromagnetic wave transmitted from the transmission antenna.

摘要： A direct injection engine includes an ignition assistance section applying energy to fuel injected into a cylinder using an injector to assist auto-ignition combustion of the fuel when the engine is within an auto-ignition combustion operation range. A start time of fuel injection is set within a period from a terminal stage of a compression stroke to a compression top dead center. The energy is applied to the fuel injected into the cylinder in a period from start of the fuel injection to an initial stage of an expansion stroke such that a time of a specific crank angle when an increase rate of in-cylinder pressure, which is a ratio of a change in the in-cylinder pressure to a change in a crank angle in motoring the engine, reaches a negative maximum value overlaps a combustion period when a combustion mass percentage of the fuel ranges from 10% to 90%.

摘要： A valve for an engine cylinder includes a head. The valve is selectively moveable between a closed position in which the head blocks a port and an open position in which the head unblocks the port. A lower stem is formed as one-piece with the head, and a thermal cavity formed within the lower stem. The thermal cavity is at least partially filled with a heat transfer medium. An upper stem is attached to the lower stem opposite the head. A thermal barrier is located adjacent a junction of the lower stem and the upper stem.

摘要： In a spark ignition engine, a thermal insulation thin layer is formed over a wall surface, facing an inside of a combustion chamber, of a base material forming the combustion chamber, and for a thermal conductivity λ [W/(m·K)], a thermal diffusivity κ [mm2/s], and a thickness L [μm] of the thermal insulation thin layer, L≧16.7×λ and L≦207.4×(κ)0.5 are satisfied. With such a configuration, a heat loss Q_total escaping from gas in a cylinder to the wall of the combustion chamber over all strokes can be reduced, and the thermal efficiency can be improved without inducing degradation of knocking due to an increase in an amount of heating Q_intake of the gas in the cylinder during an intake stroke.

摘要： A lash adjuster in which, when a plunger descends, a valve element moves to a valve-closed position without delay. A check valve (27) has a valve hole (28) penetrating through a bottom wall (17) of a plunger (12), a retainer (30) placed in a high pressure chamber (25) and vertically moving together with the plunger (12), and a valve element (29) capable of vertically moving in the high pressure chamber (25), between a valve-opened position at which the valve element (29) is separated from the valve hole (28) to be placed on the retainer (30) and a valve-closed position which is located above the valve-opened position and at which the valve element (29) closes the valve hole (28). When the plunger (12) is at a standstill, the valve element (29) is held at the valve-opened position by the self-weight.

摘要： Constant pressure internal combustion engine having compression and expansion chambers of variable volume, an elongated combustion chamber of substantially constant volume between the compression and expansion chambers, and a fuel inlet for introducing fuel into the combustion chamber where it mixes with compressed air from the compression chamber to form a mixture of fuel and air that burns as it travels through the combustion chamber. In some embodiments, the combustion chamber is folded back upon itself and has a rough, twisting interior side wall, with long, sharp protrusions extending inwardly therefrom and forming hot spots which help to provide complete combustion of the fuel mixture throughout the combustion chamber. These protrusions, together with flow turbulators within the chamber, promote complete mixing and, hence, combustion of the fuel and air in the combustion chamber.

摘要： Internal combustion engine and method with compression and expansion chambers of variable volume, a combustion chamber, a variable intake valve for controlling air intake to the compression chamber, a variable outlet valve for controlling communication between the compression chamber and the combustion chamber, means for introducing fuel into the combustion chamber to form a mixture of fuel and air which burns and expands in the combustion chamber, a variable inlet valve for controlling communication between the combustion chamber and the expansion chamber, a variable exhaust valve for controlling exhaust flow from the expansion chamber, means for monitoring temperature and pressure conditions, and a computer responsive to the temperature and pressure conditions for controlling opening and closing of the valves and introduction of fuel into to the combustion chamber to optimize engine efficiency over a wide range of engine load conditions. The relative volumes of the compression and expansion chambers and the timing of the valves are such that the pressure in the combustion chamber remains substantially constant throughout the operating cycle of the engine, and exhaust pressures are very close to atmospheric pressure regardless of the load on the engine. The engine runs so quietly and burns so cleanly that in some applications it may not require a muffler and/or a catalytic converter.

摘要： A method includes coupling a cylinder head to a cylinder block. A valve member is then moved into a valve pocket defined by the cylinder head such that a first stem portion of the valve member engages an actuator. A first portion of the biasing member is then disposed against a second stem portion of the valve member, the second stem portion being opposite the first stem portion. An end plate is then coupled to the cylinder head such that a second portion of the biasing member engages the end plate.
