The engine is the heart of any vehicle. It converts fuel into mechanical energy, powering the wheels and enabling motion. Key engine parts include the pistons, crankshaft, camshaft, and valves. Regular maintenance of these components, such as oil changes and timing belt replacements, helps prevent breakdowns and extends the engine’s usability.
