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 ...

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 ...

While the world is trying to go EV, heavy duty diesel trucks like the Ford F-250 are still the rage for those who do big jobs (or want to look like they do). Many truck owners are always on the ...

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.

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 ...

Golf balls have dimples, so they fly farther than balls that don't. Apply the same principle to diesel engines, and you have a gross oversimplification of why dimpled pistons were invented. It's a ...

An engine's displacement dictates power output based on the bore and stroke, while compression ratio influences how strong ...

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 ...
