Most of the internal combustion piston engines built for vehicles throughout history have pretty familiar core designs. The majority of fuel-burning vehicles sold today orient their pistons in inline ...

Advancements in automobile engine technology have continued to rise exponentially, specifically in the past decade, where efforts have been focused on alternative engine technology. The passenger ...

A rotary engine, often referred to as “Wankel”, owes its name to German inventor Felix Wankel, who first developed the concept. Though he initiated the design, it was the Japanese automaker Mazda that ...

With the foundation of our 383ci Chevy build in place, thanks to the installation of the forged Eagle 3-inch stroked crankshaft, it's time to move onto the rotating assembly. That means it's time to ...

EVERY so often someone tries to design a new internal-combustion engine. Few make it from the laboratory bench to the big bad world. The last serious attempt, Felix Wankel's rotary engine, lingers on ...

An engine with no crankshaft, where the pistons float on air? It’s not a dream; it’s a free piston engine and it might be the next major advance in car tech. When we think of automotive technology of ...

Everyone generally knows about piston and rotary engines, with many a flamewar having been waged over the pros and cons of each design. The “correct” answer is thus to combine both into a single ...

Antony Ingram April 30, 2014 Comment Now! Despite the recent advent of usable, talented electric vehicles, combustion engines are likely to persist for quite some time, often as a component in plug-in ...

When you consider the crazy monkey motion of reciprocating internal combustion engines it is remarkable they work as well as they do. You have eight pistons and connecting rods doing a “do-si-do” ...

Pistons are an engine-building element we like to brag about, but you won't catch many of us boasting about having cast pistons. Cast pistons are for wimps. Many of us like to talk up hypereutectic ...
