Latest Patents

Takeuchi's patent, titled "Apparatus for Controlling the Speed of an Engine," presents a sophisticated solution for managing the idling speed of an engine. This apparatus incorporates an idling speed control valve that operates within an idle passage and interacts with the intake passage both upstream and downstream of the throttle valve. The design allows for precise control over the airflow supplied to an idling engine, enhancing efficiency and performance.

The patent details a mechanism where a neutral start switch generates an instruction signal sent to the Engine Control Unit (ECU) based on the operation of a shift lever moving from neutral to drive. The ECU then calculates a duty factor to manage the increased airflow through the idle speed control valve to a specified level. This streamlined process ensures that the airflow is modulated to a predetermined magnitude, incorporating an attenuation factor that considers changes in engine speed.
