How Many Parts in a Modern Car Engine


With so many different types of engines on the market today, it can be hard to know which one is right for your car. In this article, we’ll take a look at the different types of engines and their corresponding parts. We’ll also cover some of the common problems that can occur with them, and how you can prevent them from happening.

How a Car Engine Works

A car engine is a machine that converts energy from the gasoline or diesel fuel it burns into motion. A modern engine usually has four cylinders arranged in a V-shaped configuration. The pistons are pushed up and down by the fuel/air mixture detonating at the top of the cylinder and pushing the piston down. This repeated process turns the crank, which sends power to the wheels.

The Five Parts of a Car Engine

A modern car engine contains five parts: the block, cylinder, piston, crankshaft and camshaft. The block is the primary structure of the engine and includes the cylinders and their respective pistons. The cylinder is where the fuel and air mixture is ignited by the spark from the piston and drives the wheels. The crankshaft spins the propeller or fan blades on the engine’s axle. The camshaft controls the valve timing in order to produce a variety of engine performance characteristics.

What Happens When a Car Engine Starts

When a car engine starts, the pistons in the cylinders move up and down. The crank shaft turns the crankshaft, which causes the rods and pistons in each cylinder to move back and forth. This movement drives the engine.

How to Repair a Car Engine

Wondering how to repair a car engine? There are basically four parts to every car engine – the Crankcase, Piston, Connecting Rods, and Cylinder Heads. Here’s a quick guide on how to fix them:

1. Crankcase – This contains the crank shaft and bearings. If it’s broken, the engine won’t start. Usually, you can just replace the crankcase if it’s broken.

2. Piston – The piston is at the heart of a piston engine, and it moves the air and fuel mixture in the cylinder. If it’s broken, the engine will likely not run properly. In most cases, you can just replace the piston.

3. Connecting Rods – These connect the piston to the crankshaft and are responsible for transferring energy from the pistons to the cylinders. If they’re broken, the engine will likely not run properly. In most cases, you can just replace them.

4. Cylinder Heads – The cylinder heads contain valves that allow air and fuel into and out of each cylinder during combustion. If they’re broken, it will likely prevent the engine from running properly.


In this article, we were keen to answer the question of how many parts are in a modern car engine. We discussed the role of pistons, cams and valves in driving movement within an engine, and outlined just what goes into making a modern car engine tick. Thank you for reading!
