    摘要： A cylinder head for an internal combustion engine has at least two outlet valves (1, 2), at least two inlet valves (3, 4), a spark or glow plug (6) arranged centrally between the valves (1, 2, 3, 4), and at least one injection valve (7). Coolant channels (8, 9, 10, 11, 12) accommodate a throughflow of the cylinder head with cooling liquid. The coolant channels (8, 9, 10, 11, 12) are arranged in the incident or surrounding flow region of the spark/glow plug (6) and injection valve (7) to run at a substantially acute angle in the flow direction toward the spark/glow plug (6) and injection valve (7).

    摘要： A cylinder head (1) for an internal combustion engine with liquid cooling and a liquid-cooled exhaust manifold (8) and which is arranged integrally with the cylinder head (1) includes at least one first and one second cooling chamber (4, 9) through which a coolant flows, and with the region of the exhaust manifold (8) being enclosed at least partly by the second cooling chamber. In order to ensure by way of simple production the optimal removal of heat from thermally critical regions, the first and second cooling chambers are flow-connected via at least one borehole (10) with one another.

    摘要： Improved internal combustion engine, particularly, an improved two-stroke, diesel aircraft engine. A first improvement includes a wrist pin/connection rod assembly. A plurality of fasteners extend through a wall of a wrist pin and into a wrist pin insert to secure the wrist pin to a cradle-like portion of a connecting rod. A second improvement includes a fuel injection system which cools fuel injectors with overflow fuel from a fuel pump. The overflow fuel is warmed as it cools the fuel injectors, thereby preventing ice-build up on a fuel filter in cold weather as the overflow fuel is recirculated to the fuel pump. A third improvement includes a new cylinder head cooling arrangement. The cylinder head and a cooling cap define an annular cooling passageway. Cooling fluid flows through the annular cooling passageway to cool the cylinder head. The cooling cap includes an inlet port and an outlet port which are not diametrically opposed. Accordingly, the annular cooling passageway includes a restricted portion to ensure cooling fluid flows completely around the annular cooling passageway to better cool the cylinder head. The cooling cap is adjustably mounted on the cylinder head, so that the cooling cap can be coupled to a cooling jacket independent of the location of the cylinder head on the engine or cylinder block, as when the cylinder head threads into the engine block. The same clamping device used to connect the cooling cap to the cylinder head can be used to secure the fuel injector to the cylinder head. A fourth improvement includes a cross-feed cooling passageway extending between multiple cylinder banks to provide thermal coupling between the cylinder heads and the lower crankcase of the engine, and to provide a safety arrangement for continued cooling fluid flow at least in the event a thermostat in communication with a cooling jacket should fail.

    摘要： An oil heat exchange apparatus is provided for an internal combustion engine having cylinders aligned in a cylinder row direction. The oil heat exchange apparatus includes a cylinder head having a cylinder head coolant path through which a coolant flows, a cylinder block having a cylinder block coolant path through which the coolant flows parallel to the coolant flow through the cylinder head coolant path, and an oil passage through which oil flows. The oil passage is configured and arranged to exchange heat with the coolant flowing through both the cylinder block coolant path and the cylinder head coolant path.

    摘要： In an engine having a cylinder head which forms a portion of an engine body and is provided with an intake valve operated for opening and closing operations by an intake valve operating device having an intake camshaft and an exhaust valve driven for opening and closing operations by an exhaust valve operating device having an exhaust camshaft, the intake camshaft (30) is placed higher in position than the exhaust camshaft (35) by increasing the distance between the intake camshaft (30) and a combustion chamber (17) along a cylinder axis (C) of the engine body (11) relative to that between the exhaust camshaft (35) and the combustion chamber (17). Lubricating oil is thereby enabled to be easily used for exhaust valve operating device after being used for lubrication and cooling of the intake valve operating device, thus achieving efficient lubrication and cooling of the exhaust valve operating device.
