Direct-injection engines were introduced with a promise that sounded ideal: more power, better fuel efficiency, and cleaner ...

If you ask any modern automotive nerd to name the first vehicle to feature a direct-injection diesel technology, you will likely get one of two answers. The Volkswagen Audi Group loyalist will point ...

Diesel engines lack the spark of gas engines, both literally and figuratively. They don't need a spark plug since they ignite the fuel using only compression, but also lack the 'je ne sais quoi' that ...

Direct injection engines deliver fuel at high pressure directly into the combustion chamber. When the fuel spray strikes surfaces such as the piston crown or liner, a thin liquid film forms. This film ...

Flash boiling occurs when liquid fuel under high pressure enters an environment whose pressure lies below the liquid’s saturation pressure, driving rapid vapour nucleation and explosive atomisation.

A team of engineers at the University of New South Wales (UNSW) in Sydney has figured out a way to run a diesel engine on a mix of diesel and hydrogen, dramatically lowering its emissions. Why do we ...

Until the early 1990s, many gasoline engine designs relied on carburetors to produce the fuel-air mixture needed to make the power that makes a car move. However, as the regulations around fuel ...
