摘要： A two-stroke internal combustion engine includes a diversion fin and an allowance slot. The diversion fin is a structure that has flanges at two ends and a rectangular longitudinal cross section profile. The diversion fin is clamped by a cylinder head and a cylinder block. The diversion fin extends along the diameter direction of the cylinder head and is positioned between an air inlet channel and an air exhaust channel. The diversion fin separates the air inlet channel from the air exhaust channel. The upper end of the diversion fin is provided with a transverse through groove at a position corresponding to an oil nozzle of an oil injector. The allowance slot is disposed on a piston and is positioned in the center of a combustor. The position of the allowance slot corresponds to the position of the diversion fin.

摘要： In inline four cylinder internal combustion engine (1), exhaust ports for a #2 cylinder and a #3 cylinder merge inside cylinder head (3) and form an opening serving as a single collective exhaust port. Exhaust manifold (5) has individual exhaust pipes (6, 7) for #1 and #4 cylinders and collective exhaust pipe (8), and the leading ends of these three exhaust pipes (6, 7, 8) are connected to catalytic converter (11). Exhaust gas introduction angle (θ2) of each of individual exhaust pipes (6, 7) is larger by 30-60 degrees than exhaust gas introduction angle (θ1) of collective exhaust pipe (8). Consequently, flow velocity distribution and temperature distribution in a catalyst carrier become uniform.

摘要： An engine capable of reducing the content of hydrocarbon in exhaust gas is provided. When viewed parallel to cylinder center axes, tangential virtual lines extending from endpoints of curved port central axes along tangent lines of the endpoints pass intake valve ports, straight port central axes extending from the endpoints of the curved port central axes are further away from a partition wall than the tangential virtual lines, and intake air bent through curved ports passes straight ports and is sucked through the intake valve ports along the wall between the cylinders.

摘要： In an internal combustion engine comprising a plurality of cylinders with at least one cylinder head including inlet channels extending from an inlet flange surface to a cylinder inlet and outlet channels extending from a cylinder outlet to an opening in an outlet flange surface and an oil chamber provided in the cylinder head for supplying lubricant to an actuation device for gas exchange valves, the inlet flange and the outlet flange have flat surfaces which are arranged at an angle relatively to each other so that the surface planes intersect above the cylinder head and the cylinder head, as a result, has an essentially triangular cross-section.

摘要： An EGR device for an internal combustion engine comprises: an EGR path through which a part of exhaust gas is recirculated from the exhaust gas conduit of an internal combustion engine as EGR gas to the intake path; and an EGR valve that is disposed within the EGR path and adjusts the flow rate of the EGR gas flowing through the EGR path. An curved structure EGR path from a position at which the EGR valve is disposed until a joining section (8d) merging with an intake manifold is a curved structure having a turned-back section which is curved in a cross-sectional view cutting a plane parallel to an installation plane on which the internal combustion engine is mounted. The position at which the EGR valve is disposed is higher than the joining section, and the EGR path of the curved structure slopes downward from the EGR valve side.

摘要： An apparatus includes a valve and an actuator. The valve has a portion movably disposed within a valve pocket defined by a cylinder head of an engine. The valve is configured to move relative to the cylinder head a distance between a closed position and an opened position. The portion of the valve defines a flow opening that is in fluid communication with a cylinder of an engine when the valve is in the opened position. The actuator is configured to selectively vary the distance between the closed position and the opened position.
