potential significantly to reduce local and global air pollutant emissions. This work reports on
the effects of fuelling a heavy-duty engine with late-cycle direct injection of blended hydrogen–
methane fuels and diesel pilot ignition over a range of engine operating conditions. The effect
of hydrogen on the combustion event varies with operating condition, providing insight into
the fundamental factors limiting the combustion process. Combustion stability is enhanced at
all conditions studied; this leads directly to a significant reduction in emissions of combustion
byproducts, including carbon monoxide, particulate matter, and unburned fuel. Carbon
dioxide emissions are also significantly reduced by the lower carbon–energy ratio of the fuel.
The results suggest that this technique can significantly reduce both local and global pollutant
emissions associated with heavy-duty transport applications while requiring minimal changes
to the fuelling system.
