How a Car Engine Works

Do you know how a car engine works?
It’s not that simple!

That’s why I would like to share with you this nice and easy infographic, that I just found on the website of a graphic designer and genius!
Enjoy it!



Aston Martin Vulcan

Born out of extensive motorsport experience – and using the brand’s acknowledged flair for design and engineering ingenuity – the 800-plus bhp, all-carbon fibre Aston Martin Vulcan promises truly extreme performance.

Uniquely for Aston Martin the new supercar – limited to just 24 examples worldwide – will allow owners the opportunity to precisely tailor their track day experience through a graduating scale of detailed power and dynamic performance adjustments.

“Aston Martin Vulcan is, by its very nature, a rare and thrilling supercar,” Aston Martin CEO Andy Palmer said.

“Designed and engineered to deliver a genuinely bespoke driving experience that draws on our rich heritage, this car tailors its power and handling to both the capabilities of the driver and the characteristics of the track.”

According to some rumors, the price of the supercar is about $2.3 million.



Styled entirely in-house by the Aston Martin design team led by Chief Creative Officer Marek Reichman, and with a design language hinting at the next generation of Aston Martin sports cars, this supercar is powered by the most potent iteration yet of the company’s naturally-aspirated, 7.0-litre V12 petrol engine.

With its 800-plus bhp powerplant developed in conjunction with Aston Martin Racing, this front mid-engined, rear-wheel drive sports car draws extensively on the brand’s rich GT motorsport experience.

The Aston Martin Vulcan made its world debut at the 85th Geneva International Motor Show in March 2015.



When talking about cars many people are often confused about what the words “horsepower” and “engine displacement” mean. That’s why today we are going to explain these two technical terms, which are actually simpler than you think.

HORSEPOWER (hp) is a unit of measurement of power (the rate at which work is done). In other words it’s the common measurement of an engine’s output. By pure definition, one horsepower is the power needed to lift 550 pounds one foot off the ground in exactly one second. There are many different standards and types of horsepower. The most common horsepower is 1 hp = 746 watts. This means that to convert from horsepower to watts, we have to multiply by 746. To convert from watts to horsepower, we will multiply by 0.00134. There’s no magic number for ideal horsepower, as other variables like vehicle weight, aerodynamics, and gearing all play supporting roles in the car’s overall performance.

ENGINE DISPLACEMENT is a measure of the volume in an internal engine displacementcombustion engine. Though not directly proportional to total power produced, it typically correlates strongly with output power. As cylinders move within an engine, they do work by displacing a certain volume of air. All internal combustion engines have a certain volume displaced by cylinders. In other words, it’s the volume swept by all the pistons inside the cylinders of a reciprocating engine in a single movement from top dead centre (TDC) to bottom dead centre (BDC). It is commonly specified in cubic centimetres (cc or cm3), litres (l), or (mainly in North America) cubic inches (CID). Engine displacement does not include the total volume of the combustion chamber. Resources:
