Introduction To Car Engine Technology, Part 1: The Four Stroke Engine

Introduction

The four stroke engine is the most common type of car engine in use today. It was invented by Nikolaus Otto in 1876, and it’s been used ever since. The basic concept is simple: a piston compresses air and fuel together to create combustion which drives the piston back down again, creating torque and moving the car forward as it does so. This happens four times per cycle, hence its name.

What Is A Four Stroke Engine?

The four stroke engine is the most common type of car engine. It works by using pistons to compress a mixture of air and fuel, called combustion, which then expands. This expansion pushes on a piston that causes rotation in the crankshaft.

The first two strokes are called intake and compression, while the last two are exhaust and power (also known as expansion). The movement of these four steps creates power for your car!

In contrast to two-stroke engines, four stroke engines have valves that open at different times during each cycle–they open at top dead center (TDC), bottom dead center (BDC), TDC again (since they’re closed when you start) then again later when they’re fully open after BDC

The Four Strokes Of A Four Stroke Engine

The four strokes of a four stroke engine are:

• Exhaust Cycle
• Intake Cycle
• Compression Cycle
• Power Cycle

How The Four Stroke Engine Works

The four strokes of the piston are the exhaust stroke, intake stroke, compression stroke and power stroke. In order to understand how these work together to produce power you need to know that each stroke has its own purpose. The first two are responsible for getting air into your engine where it can be compressed and converted into fuel by burning it with oxygen from outside air. The third one compresses this mixture until it’s ready for use–this is called “compression” because it increases its density (or “compressed”). Finally comes what we call “expansion”, which happens when your car starts moving forward: when this happens there’s less pressure on top of everything inside your combustion chamber so they expand outward; this makes them hotter which causes them to react more quickly with one another so they burn faster!

The four stroke engine is the most common type of car engine in use today.

The four stroke engine is the most common type of car engine in use today. It’s been around for over 100 years, and it’s easy to see why: it offers several advantages over two stroke engines, including greater efficiency and durability.

The four stroke engine works by using fuel-air mixture to create power through a series of steps known as strokes (hence the name). These are intake, compression, combustion and exhaust–each one occurring within one rotation of an internal crankshaft. Here’s how each step works:

Conclusion

We hope you’ve enjoyed our brief look at how the four stroke engine works. The next time you’re behind the wheel, take a moment to reflect on how much technology is hidden in your car’s engine. It may seem simple and straightforward on the surface, but there’s actually quite a bit going on under there!
