    摘要： A split engine control system includes a load level detector for generating a first signal in response to a relatively high engine load and a second signal in response to a relatively low engine load. A certain of the cylinders of an internal combustion engine is deactivated in response to the second signal to operate the engine on partial cylinders and activated in response to the first signal to permit the engine to operate on full cylinders. A discriminating circuit is connected to the load level detector to disable the second signal when the duration of the latter is smaller than a preset time interval which corresponds to the duration of a false indication of engine load reduction which might occur in response to gear changes during full cylinder operation.

    摘要： A modification to a multi-cylinder internal combustion engine to automatically restrict the flow of fuel to one group of the cylinders during a first phase of operation in response to a specified vacuum level generated by the operation of the other group of cylinders. In the first phase of operation, all fuel is blocked from entering the inactive second group of cylinders by a modified valving mechanism in the carburetor. In one embodiment of the invention, it is used in conjunction with throttle valve controls for each of the groups of cylinders, blocking not only fuel to the inactive group of cylinders, but also the flow of air to the inactive group.

    摘要： A method and a device for pneumatically braking and re-starting in the reverse direction a Diesel engine, comprising stopping the fuel supply to the engine, locking starting valves of the engine in an open position during the braking period, and then opening a main starting valve and the exhaust ports of the starting valves when the engine has slowed down to a rotary speed of a predetermined value.
