Excess heat is the enemy when it comes to internal combustion engines. Operating temperature is ideal, but any degree above that starts to slowly sap power, put fluids to the test, increase friction, ...

Smaller engines with fewer cylinders and less displacement could produce more power and torque by turbocharging. A turbo or turbocharger is a forced-induction device that utilizes exhaust gasses to ...

, any increase in boost pressure also increases the temperature of the air entering the engine. This is far from ideal, as it reduces the density of the air. This then means that less oxygen is ...

The key to making more power with a diesel engine is being able to add more fuel and air to the combustion chamber. However, along with the acts of compressing more air (increasing boost pressure) and ...

Everything you need to know about intercoolers, including what they are, how they work, and how they can improve your vehicle's performance. An intercooler cools air that’s been compressed by a ...

Thank you for a very informative article on turbocharging ("How to Buy Your First Turbo," May '12). Most of your technical articles are of great value, and I try to digest the information with the ...
