While the fashion in high-tech automotive developments might lean towards hybrids and electric vehicles at the moment, there’s still plenty of scope to improve the good old internal combustion engine ...

Infiniti has revealed an engine concept this year, and it is of the variable compression kind. While not the first of its type as a concept, this motor might bring a new line of internal combustion ...

A gasoline piston engine that can dynamically change its compression ratio —that is, the amount by which the piston squeezes the fuel-air mixture in the cylinder—has long been a holy grail of engine ...

The thermodynamic efficiency of an internal combustion engine is proportional to the volumetric compression ratio. However in low load areas, the engine operation does not correspond to this ...

In a conventional piston engine, the compression ratio defines the relationship between the largest and smallest volume of a cylinder - when its piston is at bottom dead centre and top dead centre ...

Does “the world’s first production-ready variable compression ratio engine” mean anything to you? For general automotive consumers, perhaps not a thing – at least, not yet. But that’s the big selling ...

In a conventional piston engine, the compression ratio defines the relationship between the largest and smallest volume of a cylinder - when its piston is at bottom dead centre and top dead centre ...

An interesting patent has been filed by Toyota for an engine with variable compression. The patent is for an engine with variable length connecting rods. The connecting rod features two hydraulic ...

It's only teasing a bit of information for now, but it will be properly unveiled during this year's Paris Motor Show. Cars are Andrew's jam, as is strawberry. After spending years as a regular ol' car ...
