Effects of Advanced Gasoline Vehicle Technologies and Fuel Properties on Emissions and Fuel Economy

摘要

The outcome of JCAP2(Japan Clean Air Program 2) Gasoline WG is reported. Three studies were carried out. The first is 'Long Driving Tests', a study of gasoline sulfur effects on fuel consumptions and exhaust emissions from SIDI vehicles under long distance accumulation tests. The second is 'Octane Number Study', a fuel economy study with varying both engine compression ratios and gasoline octane numbers. The third is 'Fuel Matrix Tests', a study of fuel property effects on emissions from J-ULEVs, using test fuels parametrically varying T50, T90 and aromatic contents.
