It's amazing that an object as simple as a piston can withstand the rigors of combustion for hundreds of thousands of miles without failing. There's a lot more to a piston than meets the eye, matey.

According to fleet executives as well as fleet maintenance managers, the death of the internal combustion engine may prove to be greatly exaggerated in spite of the excitement about electric ...

V-shaped engines like the V6 and V8 power lots of cars, but you probably never think about what, exactly, that V angle is. That's okay. Automotive engineers do.

Half a dozen countries, including the U.K. and possibly also Germany, have now laid out plans to ban gas- and diesel-powered vehicles, while tough U.S. and Chinese emissions and mileage standards are ...
