Flywheel is one of the most important engine components. It is a large and heavy metal wheel. Flywheel is attached to the back of the crankshaft to smooth out the firing impulses. It provides inertia to keep the crankshaft turning smoothly during the periods when no power is being applied.

An engine is composed of several major components; the block, the crank, the rods, the pistons, the head (or heads), the valves, the cams, the intake and exhaust systems and the ignition system.

Engine block components

• Cylinder blocks.
• Cylinder liners.
• Coolant passages.
• Oil passages.
• Crankcase.
• Integrated crankcase.
• Integrated cylinder head.
• Integrated transmission.

The engine block is one of the biggest, heaviest and important component of the internal combustion engine.

7 Main Parts of an Automobile Engine

• The Block. Your engine’s block is its main part.
• Pistons. As your spark plugs fire, the pistons pump up and down, compressing the mixture of air and fuel.
• Cylinder Head. The head is located on top of the block and seals in gases.
• Valves.
• Camshaft.
• Crankshaft.
• Oil Pan.

Why are aluminum cylinder blocks sometimes cast around a steel sleeve? A steel sleeve does not wear as quickly due to piston friction. Aluminum is lighter and dissipates heat more rapidly. The oil ring removes excess oil from the cylinder wall and flows oil to the piston pin and crankcase.

30,000 parts

In broad terms, the engine can be segregated into three key parts, the head, the block and the oil sump. 1. The cylinder head is the channel through which the fuel enters the engine chamber and exhaust gases exit. Its key components are the camshafts, valves and spark plug.

Step 2: Check Engine Compartment

• Engine oil level.
• Coolant level in radiator; condition of hoses.
• Power steering fluid level; hose condition (if equipped)
• Windshield washer fluid level.
• Battery fluid level, connections and tie-downs (battery may be located elsewhere)

In an engine many parts work together and achieve the goal of converting chemical energy of fuel into mechanical energy. Cylinder is the main body of IC engine. Cylinder is a part in which the intake of fuel, compression of fuel and burning of fuel take place. The main function of cylinder is to guide the piston.

The moving parts of an engine serve an important function—turning heat energy into mechanical motion. The principal moving parts are the piston assembly, the connecting rods, the crankshaft assembly (including flywheel and vibration dampener),the camshaft, the valves, and the gear train.

The Moving Parts of an Engine

• Pistons. The piston is a cylindrical device that sits flush within the cylindrical combustion chamber.
• Connecting Rod. The connecting rod is attached to bottom of the piston.
• Crankshaft. The crankshaft consists of a rotating shaft with several “crank pins” coming off it at different angles.
• Valves.

The timepiece with the most moving parts is the universe itself. It is also the only true “perpetual” one!

Lots of moving parts” Meaning: A complicated situation with a lot of variables or components. Usually used when it would take too long to explain something in detail.
