The compression ratio isn’t just a number: it’s one of the greatest determining factors in engine building. Compression ratio determines the type of fuel, how much boost, and has a significant ...

"Too little compression will usually result in unmet performance expectations. On the high side [too much compression] carries greater risk in tuning and potential component failure if appropriately ...

“Too little compression will usually result in unmet performance expectations. On the high side [too much compression] carries greater risk in tuning and potential component failure if appropriately ...

Strictly defined, compression ratio is the total volume above the piston at bottom dead center (BDC), divided by the total volume above the piston at top dead center (TDC). First, let's look at the ...

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 ...

For more than a century now, automotive engineers have struggled with an unavoidable balancing act when it comes to engine compression. Now, thanks to an innovation from Infiniti, they may get to ...

This is a preview. Log in through your library . Abstract The potential of a Homogeneous Charge Compression Ignition (HCCI) engine with variable compression ratio has been experimentally investigated.

The new Infiniti VC-Turbo engine (code-named KR20) is chock-full of interesting details that come with its variable-compression-ratio trick. Click on through to demystify the unique operating ...

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 ...

Though it ain't quite broke, the modern internal combustion engine could stand to see some fixing. Sophisticated as it might seem, a car's engine is still highly inefficient. Fuel infectors and ...
