Garrett is presenting two key papers at the 2017 Supercharging Conference, and will be displaying innovative technologies in turbocharging, electric boosting and connected vehicle solutions.
RDE and CO2 relevant Boosting Technologies for Passenger Cars
As more stringent emission and fuel economy legislation are implemented around the world it is evident that vehicles and powertrains will soon have significantly increased levels of Electrification.
This paper introduces an advanced simulation study based on a 2.0L Gasoline engine. It compares the potential functionality and trade-offs between a baseline boosting system and two alternatives: one utilizing an electrically driven compressor (e-Charger™) and a wastegate turbo, and the other with an electrically assisted turbocharger system (e-Turbo) only. Steady-State, Transient and potential Fuel Economy in a reference RDE Cycle as well as a WLTC are considered.
The new 1.5L TSI evo gasoline engine from Volkswagen – Miller Cycle and Turbocharging with variable turbine geometry
In addition to meeting future emission regulations, a significant reduction in fuel consumption in real customer operations with a higher vehicle performance has been the driver for the development of the new EA211 TSI evo engine generation.
As the first representative of the new generation, the 1.5L TSI evo engine starts and replaces the successful EA211 1.4L TSI 92kW series. The new 96kW engine is characterized by the Miller combustion process combined with an exhaust gas turbocharger with variable turbine geometry.
