That fresh air is squeezed into a small pocket in the center of the cylinder as both pistons come together, where finally diesel fuel is directly injected, igniting the mixture and creating the power ...

Automotive history is full of dead ends that eventually get lost to time. Seventy years ago, the free-piston engine was ...

Gasoline and diesel engines feature many differences aside from fuel type. Compared to gasoline engines, a diesel is typically a lower-revving, torquier design, hence why it's often preferred over ...

The newly formed organization will host a series of meetings of its members to exchange research results, insights and ideas regarding opposed-piston engines with hydrogen combustion. Several ...

The combustion engine has been around since the 19th century, thought up by the brilliant minds of engineers like Nikolaus Otto and Rudolf Diesel. Over the years, advancements in automotive technology ...

The team at Garage 54 replace aluminum pistons inside of an engine with custom-made plastic pistons. The engine, surprisingly, runs for longer than it has any right to run. Garage 54 specializes in ...

Throughout its short life, the automotive industry has made quick progress in many fields – from mechanical efficiency and build quality to assembly speed and volume. Chemistry is one of the crucial ...

Unless you rebuilding an engine with little to no budget you're going to upgrade to aluminum forged pistons. Besides being stronger than cast pistons, the lighter aluminum cuts parasitic power loss.

Some inherently balanced engines like flat four- and flat-six cylinders don't need balance shafts, but other cylinder counts ...
