White smoke emissions under cold starting of diesel engines
- Wayne State Univ., Detroit, MI (United States)
More stringent regulations have been enforced over the past few years on diesel exhaust emissions. White smoke emission, a characteristic of diesel engines during cold starting, needs to be controlled in order to meet these regulations. This study investigates the sources and constituents of white smoke. The effects of fuel properties, design and operating parameters on the formation and emissions of white smoke are discussed. A new technique is developed to measure the real time gaseous hydrocarbons (HC) as well as the solid and liquid particulates. Experiments were conducted on a single cylinder direct injection diesel engine in a cold room. The gaseous HC emissions are measured using a high frequency response flame ionization detector. The liquid and solid particulates are collected on a paper filter placed upstream of the sampling line of the FID and their masses are determined. A comparative study is made between white smoke in its three forms for diesel fuel (DF2) and jet fuel (JP8). The fuel accumulated in the engine during cranking plays a major role in the emissions of white smoke under cold starting conditions.
