An engine's displacement dictates power output based on the bore and stroke, while compression ratio influences how strong ...

Taking an engine compression test is sort of like checking your car's blood pressure. It's a quick and painless procedure that can reveal hidden issues.

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 ...

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 ...

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 ...
