Methods and apparatus for controlling a shutdown of an internal combustion engine

A method of controlling the shutdown of an internal combustion engine, comprising:

• receiving an ignition status indicative of a request to shutdown the internal combustion engine;
• evaluating said ignition status to determine said request to shutdown the internal combustion engine;
• and
• adjusting a throttle for a substantial termination of an intake charge of air through an intake manifold to an intake port of the internal combustion engine if said ignition status indicates said request to shutdown the internal combustion engine.

An apparatus for controlling the shutdown of an internal combustion engine, comprising:

• an intake manifold configured to conduct an intake charge of air to an intake port of the internal combustion engine;
• an electronic throttle configured to alter said intake charge of air to said intake port of the internal combustion engine;
• and
• a computerized controller configured to control said throttle such that a substantial termination of said intake charge of air is provided during the shutdown of the internal combustion engine.

An apparatus far controlling the shutdown of an internal combustion engine, comprising:

• an intake manifold configured to conduct an intake charge of air to an intake port of the internal combustion engine;
• an electronic throttle configured to alter said intake charge of air to Bald intake port of the internal combustion engine, wherein said electronic throttle includes and electric motor to move a throttle plate;
• and
• a computerized controller configured to control said throttle such that a substantial termination of said intake charge of air is provided during the shutdown of the internal combustion engine.
