You've probably heard racers talking about leakdown testing as a method of verifying engine condition. Being a hot rodder, you've probably performed a similar function by using a compression tester to ...

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 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 ...

Let's discuss something that is well known by diesel mechanics and hard-core enthusiasts but may not be fully understood by new diesel owners or people who may have heard the term "compression ...

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 ...
