However, not all innovations are equal, and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...

A.Here's a pressure-volume diagram for a combustion engine. Although rough, it is an approximation of the so-called air-standard cycle. '' Point (a) is at atmospheric pressure, after which the air is ...

We might be covering ground that's well trampled for many, but the static compression ratio of an engine is simple to understand: it's all the volume of a cylinder above the compression ring at Bottom ...

GM has filed a patent application for so-called “Multilink Cranktrains with Combined Eccentric Shaft and Camshaft Drive System for Internal Combustion Engines.” The system is designed to provide ...

There are other forms of racing where the cars are designed to be equal (e.g. Race of Champions). F1 and most other series are not that. As others pointed out, there is a long storied history of ...

Any certified gearhead knows that diesel engines do not use spark plugs. But why not? If power in an engine is created by combustion or explosion of flammable liquids, won't a spark plug in a diesel ...

Diesel engines are different from gas engines in numerous ways, including their use of high compression ratios. Here's why ...

The automotive industry continues to be a hotbed of innovation, with activity driven by factors such as auto-ignition properties of the fuel, fuel concentration, and residual rate, and growing ...

Something I've been kicking around for a while, and wanted to get opinions on: Is there a reason we can't use variable intake valve timing to "optimize" engine operation for E85 operation, while still ...
