Contributed by the Internal Combustion Engine Division of ASME for publication in the JOURNAL OF ENERGY RESOURCES TECHNOLOGY. Manuscript received November 14, 2016; final manuscript received May 24, 2017; published online June 15, 2017. Assoc. Editor: Avinash Kumar Agarwal.

J. Energy Resour. Technol 139(6), 062202 (Jun 15, 2017) (8 pages) Paper No: JERT-16-1458; doi: 10.1115/1.4036932 History: Received November 14, 2016; Revised May 24, 2017

In this study, the emissions from three passenger cars with gasoline, methanol, ethanol, and their blend were tested. The results show that the CO and HC emissions from the exhaust of the vehicles fueled with E7.5/M7.5 decrease compared with those from the vehicles fueled with the gasoline, E10 or M15, while NOx emissions increase by 7.5–25.8%. Formaldehyde and acetaldehyde are found higher for the vehicles fueled with E7.5/M7.5, whereas a series of volatile compounds become lower. Evaporative emissions of the vehicles fueled with E7.5/M7.5 were higher than those of the vehicles fueled with gasoline, by a range of 16.39–28.28%.
