The engine is the core system that makes your car go. Most modern vehicles use internal combustion engines, which work by mixing fuel and air, igniting the mixture, and using the resulting explosion to move pistons. That up-and-down motion is converted to rotational power through the crankshaft, eventually driving the wheels. The engine includes a wide range of parts, like the cylinder head, valves, camshaft, pistons, and more—all working in sync to create power.
Engines vary in size and shape, from small 3-cylinder setups to massive V8s. They can be powered by gasoline, diesel, or even electricity in the case of hybrid setups. Keeping the engine healthy involves regular oil changes, checking for leaks, and staying on top of cooling and ignition system maintenance. Fun fact: most car engines operate best around 200°F (93°C), and modern engines are designed to up to 200,000 miles with good care.
