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 ...

Meet the Birotary, a crazy new and complicated engine that has three cylinders arranged like a star, a rotating block, a ...

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 ...

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 ...

One of the many challenges facing engine designers is the need to increase power output while simultaneously retaining or improving efficiency. Although a four-cylinder engine is still an engineering ...

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 ...

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 ...

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 ...
