摘要： A vapor cooled type internal combustion engine is provided with an auxiliary reservoir and a coolant management system. The management system establishes fluid communication between the reservoir and a cooling circuit of the engine in a manner to fill the latter with liquid coolant when the engine is not in use and thus exclude contaminating non-condensible air from same, and monitors the operation of the system when operating in a closed mode to determine if too much or too little coolant has been retained in the circuit following a warm-up mode wherein the excess coolant which fills the system when cold, is displaced by its own vapor pressure. The management system also ensures that the cooling circuit is not switched from closed to open states while the possibility of superatmospheric pressures developing therein exist and thus prevents violent displacement of coolant out of the circuit to the reservoir in a manner which invites spillage of coolant and the entry of large amounts of contaminating air.

摘要翻译： 蒸气冷却型内燃机配备有辅助储存器和冷却剂管理系统。 管理系统建立储存器与发动机冷却回路之间的流体连通，以便在发动机不使用时用液体冷却剂填充发动机并由此排除来自发动机的不可冷凝空气的污染，并且监控 系统在闭合模式下操作以确定在预热模式之后循环中是否保留了过多或过少的冷却剂，其中在冷却时填充系统的过量的冷却剂由于其自身的蒸汽压而被置换。 管理系统还确保冷却回路不从闭合状态切换到打开状态，同时存在超大气压力产生的可能性，并且因此防止冷却剂以致引起冷却剂溢出的方式猛烈地将冷却剂从回路排出到储存器，并且 进入大量的污染空气。

摘要： A spark timing control system (10) for an internal combustion engine, comprises a first device (12) for sensing one of engine noise and vibration to generate an output signal corresponding thereto; a second device (20) for generating an output signal when the level of the output signal exceeds a reference value (Vr); and a third device (24) for retarding the spark timing of the engine in response to the output signal of the second device, thereby maintaining engine noise below an allowable limit.

摘要： In order to rapidly bring the temperature of the coolant in the coolant jacket of an evaporative type cooling system to a derived target value, both the rate of heat exchange between the condenser or radiator of the system and the surrounding ambient atmospheric air and the amount of coolant in the cooling circuit are varied in a manner to change the pressure and therefore the boiling point of the coolant. With the invention coolant is positively pumped to and from a reservoir which is maintained at atmospheric pressure into and out of a cooling circuit which is hermetically sealed during engine operation.

摘要： In order to permit smooth egress of coolant vapor generated by the boiling of a liquid coolant in a coolant jacket of a "vapor cooled" internal combustion engine or the like, a gutter like structure is provided in the ceiling of the coolant jacket and arranged to extend continuously above both the structures of the engine subject to the highest heat flux (e.g. the combustion chambers, exhaust valves and ports) and the surface of the liquid coolant in which the structure is immersed. This allows the vapor to rise and subsequently flow without impedence to a vent port or ports and obviate the creation of any pressure differentials within the coolant jacket which adversely effect uniform cooling of the engine.
