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 ...

Nissan brought the first, and only, variable-compression engine to market. But its future doesn't look bright. Complexity in cars is a funny thing. It’s tempting to say that it’s all bad, that more is ...

UK price (as reviewed): £28.58 inc VAT US price (as reviewed): $40.75 inc VAT Compression fittings are one of those advances in technology that you wonder how you ever did without. In fact you might ...

Honda might be looking back to early aeronautics in its latest bid to make variable compression engines simpler and sturdier. The engine is designed to take advantage of the simple crank design of ...

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 ...

While we like to think of 2002 as being part of a high-tech age, our beloved internal combustion engine hasn't really changed much in the last 50 years. We're still using pushrods and overhead valves, ...

With every passing day the Mule provides opportunities beyond our original expectations. Since the 467ci engine belongs to HPP editor Tom DeMauro, it is at our beck and call. This affords HPP the ...

Increasing an engine’s compression ratio is a proven way of unlocking extra horsepower, but there’s a point of diminishing returns. The team at Garage 54, the Russian mechanics who built a V16 using ...

Diesel engines do their hardest work in the toughest jobs, from highway semis to construction equipment, and the reason they can survive that punishment starts with how fiercely they squeeze the air ...

At first glance, the concept of engine compression is simple enough:It's the ratio of the volume of the combustion chamber and bore when thepiston is at bottom dead center (BDC) versus when it is at ...
