Honeywell 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.
What is the impact of the tightening legislation around the Worldwide Harmonized Light Vehicle Test Procedure (WLTP) in effect since September 1, 2017, and how is Honeywell supporting OEMs achieve the increasing RDE emissions targets?
New vehicle families are now being homologated using the WLTC cycle and WLTP procedure as well as provisional conformity factors. This will be extended to all models by September 2019 with tighter conformity factors and “in service testing”.
Honeywell has been working proactively with its customers to design and qualify both gasoline and diesel turbocharger products to help meet these more stringent requirements.
A word on the latest Honeywell boosting innovations working in tandem with conventional internal combustion powertrains.
Honeywell’s technical roadmap includes new generations of conventional turbochargers for both gasoline and diesel applications. It also includes electrified products for inclusion in hybrid powertrains.
2017 is a big year for Honeywell in gasoline with several high volume worldwide launches of 3rd generation wastegate turbochargers, designed for both small and larger gasoline engines. This year also marks the production ramp up of VNT for gasoline powertrains.
Key gasoline launches include the 3rd generation mono scroll turbo for 1.2L applications, the 3rd generation twin scroll turbo for 2.0L engines and the award-winning variable geometry (VNT) turbo launched this year at Geneva on the VW 1.5L engine.
