    • During operation of an internal combustion engine, structures adjacent the piston top ring turn around position and the exhaust port are exposed to high temperatures. In order to improve cooling around these adjacent structures, the heat transfer coefficient must be increased. In this manner, energy around the top ring turn around position on the cylinder liner and around the exhaust seat can be transferred through a cooling liquid and away from the adjacent structures. The present invention enhances the cooling capability within an engine by utilizing a flow controlling device disposed between a cooling liquid inlet chamber and a cylinder liner. The flow controlling device has a plurality of orifices therein. A cooling liquid from a pressurized source is communicated to the inlet chamber and passes through the plurality of orifices to impinge a predetermined peripheral portion of the cylinder liner adjacent an exhaust port. Due to the small size of the orifices, the velocity of the cooling liquid is increased as it passes therethrough. The increased velocity of the cooling liquid and the subsequent impingement upon a required, selected portion of the cylinder liner increases the overall cooling effectiveness.
    • 在内燃机操作期间,靠近活塞顶环的结构转过来,排气口暴露在高温下。 为了改善围绕这些相邻结构的冷却,必须增加传热系数。 以这种方式,围绕顶环的能量转向位于气缸套上并且排气座周围的能量可以通过冷却液体转移并远离相邻的结构。 本发明通过利用设置在冷却液入口室和气缸套之间的流量控制装置来增强发动机内的冷却能力。 流量控制装置在其中具有多个孔。 来自加压源的冷却液体与入口室相通,并通过多个孔口以冲击与排气口相邻的气缸套的预定周边部分。 由于孔的小尺寸,冷却液的速度随着其通过而增加。 冷却液体的速度增加,随后冲击到气缸套所需要的部分,总体冷却效果提高。

    • In a heat-insulating piston comprising a ceramic cylindrical member having the lower end surface thereof in contact with the outer peripheral upper end surface of a piston skirt member, a head base member having the peripheral portion thereof in contact with an inner peripheral step portion of the cylindrical member and fixed to the piston skirt member, a heat-insulating member disposed on the head base member and a ceramic thin film member disposed on the heat-insulating member and having the peripheral portion thereof bonded to the cylindrical member, this invention relates to a heat-insulating piston which inserts metallic heat-resistant members between the inner peripheral step portion of the cylindrical member and the peripheral portion of the head base member in order to prevent the occurrence of a gap between the thin film member and the heat-insulating member. To insert the metallic heat-resistant members between the inner peripheral step portion and the peripheral portion described above, the cylindrical member and the thin film member are first bonded and then the metallic heat-resistant members are softened and pushed into a groove defined between the inner peripheral step portion of the cylindrical member and the peripheral portion of the head base member, or pushed between the inner peripheral step portion of the cylindrical member and the peripheral portion of the head base portion.

    • Thin thermal barrier coating of a specified thickness of 0.002 to 0.009 inch to insulate the combustion chamber of an internal combustion engine to achieve optimum reduction of transient head flow. The coating is of an optimum thickness to reduce in-cylinder heat loss in the combustion chamber during combustion, thus increasing engine efficiency, specific power output, and reducing emissions. However, the temperature increase is not so great as to adversely affect engine lubricant life or volumetric efficiency. The invention is particularly suitable for gasoline engines as it does not cause preignition or knocking that is generally caused by insulating coatings of greater thickness. In addition, the invention is particulalry suitable for aluminum combustion chamber components. The thinner coating also results in improved reliability and durability by reducing chipping and cracking failure tendencies associated with ceramic coatings.
    • 厚度为0.002至0.009英寸的薄隔热涂层,以使内燃机的燃烧室绝缘,以实现瞬时气流的最佳减少。 该涂层具有最佳厚度,以减少燃烧期间燃烧室内的缸内热损失,从而提高发动机效率,比功率输出和减少排放。 然而,温度升高并不大,不利于发动机润滑剂寿命或体积效率。 本发明特别适用于汽油发动机,因为它不会引起通常由更大厚度的绝缘涂层引起的预点火或爆震。 此外,本发明特别适用于铝燃烧室部件。 更薄的涂层还通过减少与陶瓷涂层相关的碎裂和破裂破坏倾向,从而提高了可靠性和耐久性。

    • This disclosure relates to a turbocharged reciprocating piston type of internal combustion engine. The engine includes a block, a head fastened to the upper side of the block, and a rocker housing fastened to the upper side of the head. The head has intake air and exhaust passages formed in it between intake and exhaust openings and intake and exhaust ports of the engine cylinders. The turbocharger is mounted on one side of the engine block, and the exhaust openings are in the head on the same side as the turbocharger. Exhaust manifold ducts connect the exhaust openings with the turbocharger. The intake openings are formed in the upper surface of the head and air intake passages are formed in the rocker housing. An air intake duct and manifold connect the turborcharger with the passages of the housing. The intake air passages of the head are formed and located to provide an advantageous heat transfer relation between the intake air and the surrounding engine ports.
