摘要： A two-stroke internal combustion heat engine (1) with fuel direct injection, wherein the heat engine (1) has: at least one cylinder (2) with an internal combustion chamber (7) having a cylindrical symmetry around a first longitudinal axis (Al); a piston (8) mounted inside the cylinder (2) to slide in a reciprocating manner; a cylinder head (11) closing the combustion chamber (7) at the top; a spark plug (12) mounted through the head (11) and having a pair of electrodes (13) at the bottom; and an injector (14), which is arranged through the side wall of the cylinder (2), has a second longitudinal axis (A2) and is provided with an injection nozzle (15). The injection nozzle (15) of the injector (14) faces the head (11) to spray fuel towards the cylinder head (11), and the second longitudinal axis (A2) is inclined to form an acute angle with the first longitudinal axis (Al).

摘要： A two-stroke internal combustion engine is disclosed having opposed cylinders, each cylinder having a pair of opposed pistons, with all the pistons connected to a common central crankshaft. The inboard pistons of each cylinder are connected to the crankshaft with pushrods and the outboard pistons are connected to the crankshaft with pullrods. Each opposed cylinder further comprises an integrated scavenge pump for providing positive intake pressure. This configuration results in a compact engine with a very low profile, in which the free mass forces can be substantially balanced. The engine configuration also allows for asymmetrical timing of the intake and exhaust ports through angular positioning of the journals on the crankshaft.

摘要： A flow-through internal combustion engine comprising an arrangement for compressing air, a combustion chamber with a fuel injection arrangement and optionally an arrangement for water injection, and an arrangement for expanding exhaust gas, wherein the expansion arrangement (4) is constituted by a piston arrangement, especially of the type that produces reciprocal motion or rotational motion, and the flow of air and exhaust gas through the combustion chamber (2) is unidirectional. In an alternative solution the air compressing arrangement (1) and the expanding arrangement (4) are constituted by the same piston arrangement, especially one of the type that produces reciprocal motion or rotational motion, and the flow of air and exhaust gas through the combustion chamber is also unidirectional.

摘要： In a V-engine a reactor (24; 24') for reducing the content of undesired compounds in the exhaust gas, such as NOx, is disposed between the two rows of cylinders (4). With this positioning the reactor does not occupy space in the engine room around the engine and at the same time the reactor is kept hot by the radiation and convection heat generated by the engine when the exhaust gas is not flown through the reactor. The reactor (24') may be integral with the exhaust gas receiver (18') of the engine, preferably so that the internal cavity of the receiver is separated from the reactor by means of a partition wall (28'), thereby making it possible to pass only exhaust gas through the reactor when there is a need for purification of the gas.
摘要翻译：在V型发动机中，用于减少排气中不想要的化合物（如NOx）的反应器（24; 24'）设置在两排气缸（4）之间。通过这种定位，反应器不会在发动机周围的发动机室中占据空间，同时当排气不通过反应器时，反应器被发动机产生的辐射和对流热量保持热。反应器（24'）可以与发动机的排气接收器（18'）成一体，优选地使得接收器的内部腔通过分隔壁（28'）与反应器分离，从而使其当需要净化气体时，可能仅通过废气通过反应器。

摘要： A radial type internal combustion engine and dry sump oil scavenging system may include a crankshaft and a plurality of piston-cylinder pairs. Each piston and cylinder pair defines a combustion chamber where oil may accumulate after the engine is non-operational, e.g., shut down. Each piston may include a plurality of pass through chambers that allow oil to enter and pass through into an oil retention cavity. The accumulation of oil in the oil retention cavity eliminates the hydrolock problem and prevents the radial engine from being severely or permanently damaged upon engine startup.
