Abstract
In order to meet stricter emissions regulations and fuel consumption regulations, the upgrading of fuel quality has become one of the most important trends in the development of internal combustion engines. In this article, 89 # gasoline (G89) that is available on the Chinese market was selected as the base fuel, and five unconventional additives, ethyl tert-butyl ether (ETBE), N-Methylaniline, sec-butyl acetate, p-methylphenol and isobutanol, were added to the base fuel and named as G89-1, G89-2, G89-3, G89-4 and G89-5, respectively. The effects of these unconventional additives on a PFI vehicle were investigated. The test was carried out on a chassis dynamometer and the NEDC cycle was adopted to simulate driving conditions. The results show that, in terms of fuel consumption, G89-3 showed the best performance for decreasing fuel consumption. In terms of gaseous emissions, G89-4 decreased all four gaseous emissions, CO2, CO, THC and NOx, to a greater extent, which indicates that blending p-methylphenol into gasoline has a better potential for the vehicle to achieve cleaner emissions. In terms of acceleration performance, the five additives all shortened the acceleration time. The effects of the different additives on shortening acceleration time are basically consistent with the RON of the fuel.
Highlights
In order to deal with stricter emissions regulations, such as EPA Tier 3, Euro 6 and China 6, and fuel consumption regulations, such as Euro 6d TEMP, US Tier 4 and China 6b, the upgrading of fuel quality has become one of the most important trends in the development of the internal combustion engines [7,8,9,10]
The vehicle fuel consumption results were calculated according to the carbon balance method
It can be seen that the five additives all decreased the equivalent fuel consumption to some degree over the entire NEDC cycle
Summary
Vehicles using different energies, such as electricity vehicles, fuel cell vehicles, etc., have attracted more and more attention and have entered a period of rapid development, there is still a consensus that the internal combustion engine will continue to be the main power device for the foreseeable future [4,5,6]. Gasoline fuel characteristics have significant influence on vehicle emissions and fuel consumption. In order to deal with stricter emissions regulations, such as EPA Tier 3, Euro 6 and China 6, and fuel consumption regulations, such as Euro 6d TEMP, US Tier 4 and China 6b, the upgrading of fuel quality has become one of the most important trends in the development of the internal combustion engines [7,8,9,10]
