Abstract
A novel spin control system for an engine-driven wheeled vehicle for reducing the power applied to driven wheels of the vehicle when an incipient wheel spin is detected. A normally closed electrically-actuated intake manifold valve is mounted on the intake manifold of the engine for actuation to an open position by an electronic circuit which detects an incipient wheel spin via wheel speed sensors. With the intake manifold vented to atmosphere via the open intake manifold valve, engine intake manifold vacuum drops automatically throttling down the engine irrespective of the carburetor throttle position to reduce the power input to the spinning wheel or wheels thereby effectively counteracting the incipient spin condition.
