"Gas-powered" refers to devices or vehicles that operate using gasoline as their primary fuel source. This includes a wide range of equipment, such as cars, lawnmowers, and generators. Gasoline is a fossil fuel derived from crude oil, and it is commonly used because it provides a high energy output, making it effective for powering engines. Gas-powered engines typically work by igniting a mixture of air and gasoline within a cylinder, which creates a controlled explosion that drives a piston. This process converts chemical energy from the fuel into mechanical energy, allowing machines to perform various tasks. Examples of gas-powered vehicles include cars, motorcycles, and trucks.
