Abstract

A car with dual power system comprises a normal fuel engine car and a compressed natural gas bottle under the back base of the car. On the natural gas bottle a nozzle links to a gas splitter through a tube. The gas splitter links to a solenoid valve through a tube. The solenoid valve links to a gas box whereon the box several nozzles link to the engine. On the engine pipe installs an oxygen sensor and a triple catalyst converter. On the body of the car installs an inducted draft which links to the engine through a tube. In the body of the car installs ECU, simulator, and on the control panel installs a fuel-gas switch. Through accurate control by stepper motor, solenoid valve and nozzle, ECU to switch from fuel to gas or vis-a-vis and the rate of gas to air for a full combustion.
