This work investigates the implications of natural-gas composition on the combustion in a
heavy-duty natural-gas engine and on the associated pollutant emissions. In this engine …

The use of pilot-ignited, direct-injected natural gas fuelling for heavy-duty on-road
applications has been shown to substantially reduce NOx and particulate matter emissions …

High-pressure direct-injection (HPDI) in heavy duty engines allows a natural gas (NG)
engine to maintain diesel-like performance while deriving most of its power from NG. A small …

In this paper, the combustion process and emissions of a heavy-duty engine fueled with
directly injected natural gas and pilot diesel were experimentally explored. The experiments …

Black carbon (BC) emissions from shipboard diesel engines are the next potentially
important issue of interest to the International Maritime Organization (IMO) and are …

The morphology and nanostructure of soot from different engines were studied. The soot
samples were collected from a 1.9 L Volkswagen light-duty diesel (LDD) engine for two …

Linear hydrogen engine is a new type of energy conversion device to supports variable
compression ratio operation for clean emission. However, the new hydrogen engine using …

The detailed combustion kinetic processes of a high-pressure direct injection (HPDI) natural
gas (NG) marine engine was investigated in the present work. A postprocessing code was …

To maximize payback for operators, it is important that natural gas engines for heavy-duty on-
road applications minimize fuel consumption. To directly replace a diesel engine for a given …

Natural gas is an abundant and inexpensive fuel in North America. It produces lower
greenhouse gas emissions than diesel fuel when burned in an internal combustion engine …
