Getting an engine compression test for your car is a bit like having your blood pressure taken. It sounds complicated without context, but it's a relatively straightforward and painless procedure that ...

Intake, compression, power, then exhaust. Every 4-stroke engine ever made – about 80% of all engines currently in existence – function on this principle – even rotary engines. But now, Porsche has ...

A two-stroke engine combines intake (“scavenging”) and compression into one stroke, then ignites the charge and exhausts it on the next stroke. Unlike a four-stroke and its every-other-stroke power ...

As you may know, an engine's compression ratio is directly linked to its combustion efficiency. All else being equal, higher-compression engines tend to make more power while offering better fuel ...

The defining characteristic of a two-stroke engine is to fire (combust) every time the piston is at top dead center. This makes them highly power dense, but also notoriously makes two-stroke engines ...

Anyone who appreciates simplicity of design and efficiency of operation has to like small two-stroke-cycle engines that power construction tools such as cut-off saws, rammers and breakers. Producing ...
