Abstract
A first speed detecting means detects whether the engine speed has fallen below a prescribed level. A second speed detecting means detects whether an accelerator pedal angle has been changed at a speed higher than a predetermined value. A third speed detecting means is provided to detect whether the speed of the automobile is equal to, or higher than, a predetermined value. Upon receipt of the output signals from the first, second and third speed detecting means, a solenoid drive circuit drives engine vibration absorbers for a predetermined period of time. More specifically, the circuit energizes solenoids for this period. The solenoids rotate the thus rotary valves of the absorbers, thus closing the orifices of the absorbers. As a result, the absorbers generate great forces damping the back-and-forth motion of the engine. The vibrations of the engine are therefore not transmitted to the chassis of the automobile.
