摘要

Our research objective is to clarify the effect of using diesel fuels made from unconventional petroleum sources (GTL, tar sand, etc.) on the emissions and performance of various regulation-compliant vehicles, focusing on cetane number and cyclic compounds. The results of emission tests showed that improved vehicle technologies such as engine control and aftertreatment devices improved robustness to fuel properties. The emissions from a J-2003 reg.-compliant vehicle (Vehicle A) changed with cetane number and cyclic compounds, whereas the tailpipe emission levels from a J-2005 reg.-compliant vehicle and engine (Vehicle B, Engine C) and from a J-2009 reg.-compliant vehicle (Vehicle D) were very low regardless of fuel properties, when the cetane number was above 45 (minimum value of Japanese Industrial Standard). The results of vehicle performance tests also showed that improved vehicle technologies such as engine controls improved the robustness to fuel properties. When using Vehicle A, white smoke at cold temperature, total hydrocarbons (THC) at engine starting, and accelerating time at normal temperature varied with cetane number and cyclic compounds. The same tendencies for white smoke and THC were observed when using Vehicles B and D, whereas the effects on the accelerating time of Vehicles B and D were small.
