N2 - This work describes the improvements on exhaust emissions and cold start obtained through utilization of a new type of cold-start auxiliary system for ethanol-fueled engines. Lower amounts of the gasoline used to help cold start and of ethanol injected during cold start and warm-up were used via introduction of a fuel injector in the new cold-start auxiliary system. The redesigned system allowed for faster and uniform cold start, in comparison to the conventional system, of around 31.1%. Reductions of raw hydrocarbon and carbon monoxide emissions in the cold stage of the FTP-75-based emissions test cycle were about 8.6 and 17.2%, respectively, while oxides of nitrogen and aldehyde emissions remained unchanged.
