Gasoline vehicles are cars and trucks that use gasoline as their primary fuel source. They have internal combustion engines that convert the energy from gasoline into mechanical power, allowing the vehicle to move. These vehicles are widely used around the world due to their availability and relatively low cost. The operation of gasoline vehicles involves a series of processes, including fuel injection and ignition. When the driver presses the accelerator, the engine burns gasoline, producing energy that powers the vehicle. While gasoline vehicles are popular, they also contribute to air pollution and greenhouse gas emissions, leading to discussions about alternative fuels and technologies like electric vehicles.
