Development of Valve Train Configurations Optimized for Cold Start and Their Effect on Diesel Soot Emission

Maniatis, Panagiotis; Erforth, Daniel; Wagner, Uwe; Koch, Thomas

Abstract:
The continuous pursuit of more efficient diesel engines and the stricter emission regulations with the introduction of the Real Driving Emissions test (RDE) necessitate further investigations of heating strategies and their suitability in terms of series production. Under these circumstances heating strategies of a variable valve train for a single-cylinder research diesel engine have been first simulated and then experimentally tested at the Institute of Internal Combustion Engines of the Karlsruhe Institute of Technology (KIT). By combining statistical experimental design (DoE) and 1-D gas exchange simulations, empirical DoE models for the design of suitable camshaft configurations have been established. ... mehr
