Illustrated with maps, plots, and diagrams, this report covers results of a performance and emissions benchmarking study carried out on a 2018 model VW Golf TSi, with a 96 kW EA211 Evo 1.5 litre 4-cylinder gasoline engine, with a claimed 116 g/km CO2.
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
The key features of the engine and how they are deployed to achieve class-leading fuel efficiency with Euro 6 emissions compliance, in a vehicle which is seen as a benchmark for its class for quality, are explained.
Interesting features of this innovative engine include:
- High compression ratio
- Miller cycle through EIVC
- Variable Geometry Turbo
- Cylinder deactivation
- Coolant control module
- High pressure fuel system with multiple injections
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.
