Technical Examples

An oxygen-detecting voltage controlling device includes an air filter, an electromagnetic valve, and a controlling circuit board, which is electrically connected to an engine computer for obtaining a current rotating speed value of an engine and sending a stable voltage to the engine computer to stop the engine computer from making correction by increasing amount of petrol injected through an injection nozzle; two adjustment knobs are fitted on the oxygen detecting and voltage controlling device and connected to the controlling circuit board for setting first and second rotating speed values respectively; the controlling circuit board will be activated and start sending a stable voltage to the engine computer immediately after rotating speed of the engine reaches the first rotating speed value; the controlling circuit board will be turned off and stop sending a stable voltage immediately after rotating speed of the engine reaches the second rotating speed value.
