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

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 ...

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 ...

As we begin the last article in this series on the basics of the internal combustion engine, let's stop to review what we've covered during the last five articles. We began last May by detailIing the ...
