    • Herein disclosed is an internal combustion engine of ignition timing controllable type for use with an automotive vehicle. The internal combustion engine includes, as customary, an intake system including a carburetor having a throttle valve, a distributor, and an ignition timing regulating device connected to the distributor and having a diaphragm chamber to which a control vacuum is supplied. The internal combustion engine further includes a first port from which a carburetor vacuum having relationship to the opening of the throttle valve is taken out, a second port from which an intake vacuum is taken out, and a first direction control valve operable in relationship to the speed of rotation of the internal combustion engine or to the running speed of the automotive vehicle. The first and second ports are selectively connected to the diaphragm chamber of the ignition timing regulating device by way of the first direction control valve, so that during a low speed driving condition of the engine the intake vacuum taken out from the second port may be supplied to the diaphragm chamber to retard the ignition timing, so that during a high speed driving condition of the internal combustion engine a low carburetor vacuum taken out from the first-named port may be supplied to said diaphragm chamber to advance the ignition timing, and so that upon deceleration from a high speed driving condition a high carburetor vacuum taken out from the first port may be supplied to the diaphragm chamber to retard the ignition timing.
    • 这里公开了一种用于机动车辆的点火正时可控型内燃机。 内燃机通常包括具有节流阀,分配器以及点火正时调节装置的化油器的进气系统,其连接到分配器并且具有供给控制真空的隔膜室。 所述内燃机还包括第一端口,从所述第一端口取出与所述节流阀的开度有关的化油器真空,从所述第二端口取出进气真空;以及第一方向控制阀, 内燃机的转速或机动车辆的行驶速度。 第一和第二端口通过第一方向控制阀选择性地连接到点火正时调节装置的隔膜室,使得在发动机的低速行驶状态期间,可以提供从第二端口取出的进气真空 到隔膜室以延迟点火正时,使得在内燃机的高速行驶状态期间,可以将从第一命名端口取出的低化油器真空度供给到所述隔膜室以提高点火正时,因此 在从高速行驶状态减速时,可以将从第一端口取出的高化油器真空供给到隔膜室以延迟点火正时。
