内燃机活塞位移与曲轴转角存在着一定的关系,因此若已知曲柄半径和连杆长度尺寸,便可通过测量活塞至上死点的距离来确定曲轴的相位。这在内燃机修理中具有一定实际意义。为此,本文拟订了电算程序,用来确定要求供油(点火)提前角下的活塞位移数值。由内燃机燃烧规律决定,为获得最佳的动力与经济性能,必须在其压缩行程上死点 Engine piston displacement and crankshaft rotation there is a certain relationship, so if you know the crank radius and connecting rod length size, you can measure the piston to the top dead center to determine the phase of the crankshaft. This has some practical significance in the internal combustion engine repair. For this purpose, a computer program has been developed to determine the value of piston displacement at an advance fueling (ignition) required. Decided by the internal combustion engine combustion rules, in order to obtain the best power and economic performance, must be in its compression stroke dead center
