Engine System

Engine Components and Functions by Our Professionals

The engine is the heart of the vehicle, responsible for converting fuel into mechanical power. The major components include:

• Cylinder Block – Houses the pistons and crankshaft.
• Cylinder Head – Contains the valves and camshaft.
• Pistons and Connecting Rods – Convert fuel combustion into motion.
• Crankshaft – Transfers rotational motion to the transmission.
• Camshaft – Controls valve timing.

Common Engine Problems and Repairs by Our Professionals

• Engine Overheating – Check coolant levels, thermostat, and radiator.
• Rough Idling – Inspect spark plugs, fuel injectors, and air filters.
• Loss of Power – Diagnose fuel system, ignition system, and sensors.
• Excessive Oil Consumption – Check for leaks and worn piston ring
