摘要： The present invention is to provide an electronically controlled fuel injection type two-stroke engine wherein the intake air amount can be determined with precision so that the fuel injection amount can be properly controlled in conformity with the varying conditions of the exhaust pressure, to thereby achieve an optimal air-fuel ratio and hence improve the output power, the fuel consumption and the exhaust performance.For the computation of the correction value to the fuel injection amount based on the intake passage pressure, the actual throttle opening and engine speed are detected, and the intake pressure value P is detected at the same time. Then the corresponding basic intake pressure value is selected from the basic intake pressure map so as to calculate the difference between the basic intake pressure value and the detected intake pressure value. This difference corresponds to the difference in exhaust pressure between the base state and the actual run state (exhaust pressure varies depending upon the conditions such as the boat speed, forward/backward mode, the mounted position (height) and the number of the mounted engines and the like). From this difference, the correction value to the fuel injection amount based on the intake pressure is computed.
摘要翻译： 本发明提供一种电控燃油喷射型二冲程发动机，其中可以精确地确定进气量，使得能够根据排气压力的变化条件适当地控制燃料喷射量，从而实现 最佳空燃比，从而提高输出功率，燃油消耗和排气性能。 为了基于进气通道压力计算出燃料喷射量的校正值，检测实际节气门开度和发动机转速，同时检测进气压力值P. 然后从基本进气压力图中选择相应的基本进气压力值，以计算基本进气压力值和检测到的进气压力值之间的差。 该差异对应于基础状态和实际运行状态之间的排气压力差（排气压力根据船舶速度，前进/后退模式，安装位置（高度）和安装的发动机的数量等条件而变化 等等）。 根据该差异，计算基于进气压力的燃料喷射量的修正值。

摘要： An engine generally performs compression, explosion, exhausting and scavenging strokes sequentially, and includes an engine driving control apparatus including a detector for detecting a position of an explosion stroke, a detector for detecting instantaneous rotation speed of the crankshaft, and a control unit which receives input from the explosion stroke position detector and the rotation speed detector. The control unit performs the steps of judging a combustion state from an increasing rate of a rotation speed of the crankshaft in each explosion stroke, intentionally increasing or reducing an amount of fuel injection, calculating variation in said combustion state and correcting said amount of fuel injection so as to enhance the combustion state.
