Engine Repair in Rockwall, TX
How does an engine work?
Chevrolet, Honda, Mercedes-Benz, Ford, and other makes may have different types of engines inside them, but they all work the same way. Simply put, an internal-combustion engine (the engine found in vehicles) is a heat engine that converts energy from the heat of burning gasoline to mechanical work, or torque. The torque is applied to the wheels, which make your car move. Engines have pistons that move up and down metal tubes called cylinders. Pistons are connected to a crankshaft via rods, and move up and down to power the crankshaft, which then power the wheels of your car. Vehicles will have between 2 and 12 cylinders in its engine.
An engine’s pistons are powered by thousands of controlled explosions created by mixing fuel with oxygen, creating combustions. The heat and expanding gases from these mini-explosions push down on the piston in the cylinder, causing movement. Engines need air (namely oxygen) to burn fuel. During the intake stroke, valves open to allow the piston to act like a syringe as it moves downward, drawing in ambient air through the engine’s intake system. When the piston reaches the bottom of its stroke, the intake valves close, effectively sealing the cylinder for the compression stroke, which is in the opposite direction as the intake stroke. The upward movement of the piston compresses the intake charge. We at Horizon Auto Center in Rockwall know all about how engines work, and can make the appropriate repairs as efficiently as possible.
