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

The clearances inside diesel injection system parts are closer than those found in any other technology. The plungers and needle valves in injectors need to fit tightly to ensure precise metering and ...

Port fuel injection (PFI) was a major milestone in the early '80s. The integration of PFI rapidly changed the way fuel was delivered by increasing fuel economy and improving engine performance. Even ...

Numerous studies have blended cetane number improver (CNI) in diesel engine fuels for compensating the drop in cetane number (CN) when alcohol/biodiesel fuel is blended with diesel fuel. However, the ...

UNSW researchers have prototyped and tested a retrofit system that converts diesel engines to run on 90% hydrogen, radically reducing both carbon dioxide and nitrous oxide emissions while boosting ...

Hydrogen has garnered significant interest as a viable renewable energy source capable of revolutionizing conventional fuel systems. This study investigates the impact of engine load and liquid fuel ...

If you’re in fleet management or the construction industry, you undoubtedly have machines that run on diesel fuel. In addition to large trucks, more than 75% of all heavy construction equipment uses ...

We often talk about the benefits of fuel injection on off-road vehicles. Generally, these systems run more reliably than carbureted systems, but they are, at the end of the day, a bit more complex ...

"Common rail." It is a term that at this point is universally known across the entire diesel space. However, for uninitiated or new enthusiasts, the term refers to the manner in which late-model/newer ...

A retrofit system that converts diesel engines to operate on 90% hydrogen has been prototyped and tested by University of South Wales (UNSW) researchers. This system drastically reduces emissions of ...
