CI2-2 Liquid Spray Penetration Length during Late Post Injection in an Optical Light-Duty Diesel Engine(CI: Compression Ignition Engine Combustion,General Session Papers)

Abstract

The present study is carried out on a light duty direct-injected diesel engine with Bowditch type optical access. Planar laser induced Mie scattering images, recorded at 20 kHz, are used to follow the evolution over time of the liquid phase of the jets. Different fuel injection strategies for diesel particulate filter regeneration are investigated. An additional focus is put on the fuel effects. The Swedish standard diesel fuel MK1 and a reference fuel free of Rapeseed Methyl Ester (RME) are tested. A Biodiesel fuel composed of 10% of RME is also tested in order to evaluate the impact of this blend on the liquid spray penetration length.
