Detailed Investigation into the Effect of Ozone Addition on Spark Assisted Compression Ignition Engine Performance and Emissions Characteristics
Sayan Biswas,Isaac Ekoto +1 more
Abstract: The impact of 50 ppm intake seeding of ozone (O3) on performance and emissions characteristics was explored in a single-cylinder research engine operated under lean spark assisted compression ignition (SACI) conditions. Optical access into the engine enabled complementary crank angle resolved measurements of in-cylinder O3 concentration via ultraviolet (UV) light absorption. Experiments were performed at moderate loads (4 5 bar indicated mean effective pressure) and low-to-moderate engine speeds (80

A Conceptual Model of DI Diesel Combustion Based on Laser-Sheet Imaging*
TL;DR: In this paper, a phenomenological description of how direct-injection (DI) diesel combustion occurs has been derived from laser-sheet imaging and other recent optical data, which is summarized in a series of idealized schematics that depict the combustion process for a typical, modern-diesel-engine condition.
