Diesel engines are different from gas engines in numerous ways, including their use of high compression ratios. Here's why that is and what it means.

The debate centres on the mandated reduction in compression ratio from 18:1 to 16:1 for the new power units, and ...

With Infiniti having recently revolutionized internal combustion engines by the introduction of a variable compression ratio mill, we're here to take the time to zoom in on the tech introduced by the ...

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 ...

Diesel engines do their hardest work in the toughest jobs, from highway semis to construction equipment, and the reason they ...

Turbocharging has mostly not lived up to its billing of being the savior of internal-combustion engine technology. Earlier this decade, facing increasing fuel economy requirements, automakers rushed ...

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 ...

A NEW BARRIER to higher compression ratios has recently become apparent — engine rumble! This phenomenon will prevent further increases in compression ratio unless corrective measures are taken. This ...

A fundamental difference between gasoline and diesel engines is that a gasoline engine uses spark ignition while a diesel engine uses compression ignition. Before we delve deeper, let's understand how ...

Even before the 2026 calendar year has begun, the first controversy under F1's new ruleset has already surfaced. It concerns the engine regulations, and more specifically the compression ratio of the ...
