There are several types of engine compression testers. Be sure to use the correct type for your specific engine, otherwise ...

Performance diesel engines are usually the realm of European automakers, but the highest-revving diesel actually comes from ...

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 ...

Assuming a properly tuned engine, there are three factors that contribute to poor streetability: long cam duration, high compression ratios, and excessive cruise rpm. Since cam selection is largely ...

"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 ...

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 ...

What is compression ratio? An explanation of compression ratio; what it means and why it is important. Why some cars need ...

Apart from the very curious, not many people ask why diesel engines, compared to gasoline, run higher compression ratios. The argument is reasonably straightforward and starts with fuel ...

Pretty simple question actually (or so my ignorant mind thinks): At what compression ratio would an engine benefit from higher octane fuel? The Focus I drive is just over 10:1, and I've heard some say ...

Installing a recycle valve in parallel with the antisurge valve of a turbine-driven multistage (low pressure/high pressure) centrifugal compressor, in combination with control system modifications, ...

A refrigeration system’s compression or pressure ratio is defined as the absolute discharge pressure divided by the absolute suction pressure. Calculating this ratio can be a big help when it comes to ...
