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 ...

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 ...

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 ...

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 ...

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 ...

Despite being in use for more than a century, combustion engines are still way to complex and inefficient in turing fossil fuel to mechanical work. Naturally, engineers have been battling their way ...

Once upon a time, we dropped a budget-built 360 in a '74 Challenger and ran 12s on the cheap, but that was over 15 years ago when a 12-second e.t. was quick and respectable. Times have changed. Your ...

Bore and stroke are important measurements when it comes to calculating an engines displacement, and the kind of performance an engine offers.

German aerospace researchers are showing off a high-efficiency powerplant concept which combines geared-fan architecture with a piston-engine core. While unlikely to enter service before 2050, the ...

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 hybrid and range-extended electric ...
