With the revived interest in hydrogen (H 2) as a direct combustion fuel for engine
applications, a computational study is conducted to assess the characteristics of H 2 direct …

Experiments have shown that ducted fuel injection (DFI) effectively reduces soot emissions
from direct-injection diesel engines. Although many computational studies have evaluated …

In conventional diesel combustion (CDC), a centrally located multi-hole injector supplies fuel
radially outwards. This study introduces and explores the concept of peripheral fuel injection …

Compared to the conventional diesel combustion engine that is equipped with a single
centrally installed injector, the multi-injector spray-combustion concept has the potential to …

High-pressure isobaric combustion adopted in the double compression expansion engine
(DCEE) has the prospect to achieve higher thermal efficiency compared to conventional …

High-pressure internal combustion engines promise high efficiency, but a proper injection
strategy to minimize heat losses and pollutant emissions remain a challenge. Previous …

Realizing the potential of the gasoline direct injection (GDI) concept lies in effectively
stratifying the charge at different engine operating conditions. This is generally obtained by …

The insufficient level of atomization of the fuel drops in direct-injection engines is a major
cause of pollutant emissions because of the incomplete combustion process. The fuel …

Numerical studies investigated how multiple injectors can reduce the high heat losses
associated with swirl, as a further attempt to enhance thermal efficiencies of high-pressure …

The present study shows the impact of multiple injectors with distinctive spray and injection
angles on engine efficiency, heat transfer (HT), and exhaust losses. It is well known from …
