Internal combustion engines power more than 250 million vehicles in the U.S. They are mechanical marvels providing drivability and durability to motorists worldwide, but how do they work? This video explains just that. In basic terms, combustion occurs within the engine as a result of igniting a fuel and gas mixture. Within a fixed cylinder, a fuel and air mixture is ignited by a spark from the spark plugs.
If any of these parts aren’t functioning properly, transmission repairs may be needed.
The resulting combustion causes thermal expansion, which pushes against pistons which in turn rotate the crankshaft. This movement is then channeled through a system of gears in the powertrain, which ultimately drives the vehicle’s wheels. This process involves many parts such as the transmission, driveshaft, and axles. A basic understanding of a car engine is a great aid to vehicle owners when it comes to maintenance. A knowledgeable driver will be in a better position to know what their vehicle needs. Knowledge is key to keeping a car running smoothly for longer.
