A two-stroke exhaust pipe features a unique shape with varying diameters and an expansion chamber, which is specific to ...

One of the most significant contributions in the history of propulsion technology came from a 19th-century engineer named Rudolf Diesel. While his idea was patented in the 1890s, it wouldn't be until ...

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 ...

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

Two-stroke engines have largely fallen out of fashion when it comes to newer vehicles. However, GM appears to have not ...

Gearheads and faithful Jalopnik readers already know the basics of an engine's bore and stroke, but for those that might be new here, let's dip our toes in the shallow end. An engine's bore refers to ...

It looks like GM is working on modernising two-stroke engines by tackling their emissions problem. This could open a whole new chapter for internal combustion. It’s been a while since two-stroke ...
