Abstract: An improvement to loop-scavenged two-stroke internal combustion engines with an intake valve (7) engaging a seat (10) for fresh air intake, and an exhaust valve (8) engaging a seat (13) for combustion gas exhaust, is disclosed. The valves are arranged in such a way that the fresh air intake scavenges a susbtantial part of the burnt gases. In at least one of said valves, the valve surface (21) located downstream from the valve face (9) and the surface (23) of the downstream extension of said seat (10) are configured in such a way that they form a substantially isentropic diffuser.

Abstract: Internal combustion engine comprising a cylindrical work chamber (1) with a piston (3) sliding therein, said work chamber being closed by a cylinder head (4), a device (5) operating in two stroke mode, for injecting liquid fuel atomized under high pressure, a system for loop scavenging through the cylinder head and two valves having the same cylindrical form and axes. The outer inlet valve (7) cooperates with a cylinder head seat (15), the other valvebeing an exhaust valve (6) of tubular shape which has a surface bearing against a seat (16) formed in the lower portion of the inlet valve (7). The inle valve opens into the work chamber and the exhaust valve opens in the opposite direction, thereby delimiting, between them, an exhaust passage (8). The injection device (5) opens into the work chamber substantially at the centre of a central hub (21) on the cylinder head, the exhaust valve (6) sliding along said hub.

Abstract: In the head housing (1) there are two mains: for air suction (A) and for air exhaust (B). The concentrical interrelation of these two mains enables the maximum possible size of the main openings which allow the necessary quantity of air for combustion into the cylinder, whereas in the exhaust process the resistance is much smaller due to the size of the main opening. The exhaust main (B) is closed by one valve (2) which is opened by one cam (5) on the camshaft (6). The suction main (A) is closed by a profiled ring (7) which is opened by two cams (5a) on the camshaft (6). This technical solution allows the engine to "breathe more easily", which has an immediate effect on the fuel consumption, engine power, quality of exhaust gases, economy of fuel consumption, and longevity in exploitation.
Abstract translation: 在头部外壳（1）中有两个电源：用于吸气（A）和排气（B）。 这两个电源的同心相互关系使得主开口的最大可能尺寸允许必要量的空气燃烧到气缸中，而在排气过程中，由于主开口的尺寸，阻力要小得多。 排气主体（B）由一个由凸轮轴（6）上的一个凸轮（5）打开的阀（2）封闭。 吸入主体（A）由凸轮轴（6）上的两个凸轮（5a）打开的成型环（7）封闭。 该技术解决方案允许发动机“更容易地呼吸”，其对燃料消耗，发动机功率，废气质量，燃料消耗的经济性和开发寿命具有即时的影响。

Abstract: An internal combustion engine is provided in which an intake valve (9), which opens and closes an intake valve hole (7) formed in a cylinder head (3) so as to face a combustion chamber (5), has a hollow structure, and an exhaust valve hole (22) formed in the intake valve (9) is made to open and close by an exhaust valve (18) coaxially housed within the intake valve (9). The intake valve hole (7), which faces the combustion chamber (5), communicates directly with an intake port (8), and the exhaust valve hole (22), which faces the combustion chamber (5), communicates with an exhaust port (14) via an exhaust passage (21) formed within the hollow intake valve (9). It is thereby possible to ensure that the intake valve (9) has a large opening area, thus increasing the intake charging efficiency and, furthermore, since exhaust gas that has just come out of the combustion chamber (5) does not make direct contact with the cylinder head (3), which has a large heat capacity, any decrease in temperature of the exhaust gas can be minimized, thereby utilizing waste heat effectively.
Abstract translation: 本发明提供一种内燃机，其中，使形成于气缸盖（3）内的进气阀孔（7）开闭以面对燃烧室（5）的进气阀（9）具有中空结构， 和形成在进气门（9）中的排气门孔（22）通过同轴地容纳在进气门（9）内的排气门（18）打开和关闭。 面向燃烧室（5）的进气阀孔（7）直接与进气口（8）连通，面对燃烧室（5）的排气阀孔（22）与排气口 （14）通过形成在所述中空进气阀（9）内的排气通道（21）连通。 因此可以确保进气门（9）具有大的开口面积，从而增加了进气充气效率，此外，由于刚刚从燃烧室（5）出来的排气不直接接触 可以使热容量大的气缸盖（3）的排气温度的降低最小化，从而有效地利用废热。
