This engine performance and emissions benchmarking study was carried out on a 2019MY Ford Fiesta ST with Dragon 1.5 litre gasoline engine; rated at 147 kW with 136 g/km CO2 claimed for this relatively high-performance vehicle.
The full report covers results and analysis from the vehicle emissions tests and engine dyno mapping at both hot engine conditions and warm-up (50°C coolant) conditions. As well as expert analysis, comparisons are made to the Ricardo database scatter to add perspective to the results.
Illustrated with maps, plots, and diagrams, it explains the key features of the engine and how they are deployed for high specific power output with Euro-6d emissions compliance. Interesting features of this innovative engine include:
- Dual fuelling systems – GDI and PFI combined
- Cylinder deactivation – claimed a first for a 3-cylinder engine
- Wide Lambda 1 operation even at high power output, with integrated exhaust manifold and high temperature turbine
- Inlet and exhaust VVT
- Low friction measures include offset crank and 2-stage variable displacement oil pump
The Ricardo EconoMark approach to engine benchmark testing ensures representative engine performance and accurate, repeatable data from an engine dyno. The focus is on fuel economy/CO2, regulated exhaust emissions, and performance of the engines in their passenger car applications.
