• Ricardo has a large database of engine data across
a wide range of engine sizes, technology levels
and emissions standards
• A selection of the database was chosen to
represent light duty diesel engines and
cross plot parameters including
BSFC, BS NOx, injection timing,
rail pressure…
Engine mapping
The report also compares some key test results from the EA288
engine mapping to the Ricardo benchmarking database
