Abstract:
In this study, A Gasoline Passenger car (Euro IV) was experimentally investigated for performance and emissions on three different fuels i.e. Gasoline, (Liquefied Petroleum Gas) and DME (Di-methyl ether) blend with concentration of 20% by mass in LPG (DME20). In particular, emission characteristics (including Hydrocarbon, CO, NOx and CO2) over the Modified Indian Driving Cycle (MIDC) and fuel economy were investigated at the Vehicle Emission Laboratory (VEL) at the CSIR- Indian Institute of Petroleum, Dehardun, India. The experimental results showed that Vehicle comply with Euro IV legislation on gasoline and LPG fuel showed higher NOx Emissions on DME 20 fuel. LPG kit was reconfigured for DME and LPG blend to bring down the emissions within the specified emission limits. The Emission values observed for DME20 were 0.635 g/km (CO), 0.044 g/km (THC), and 0.014 g/km (NOx) against the Euro IV limits of 1.0 g/km, 0.1 g/km and 0.08 g/km, respectively. The vehicle driveability over the Modified Indian Driving Cycle (MIDC) was comparable for DME 20 with gasoline and LPG fuel and vehicle could achieve the maximum acceleration and speed of the MIDC. Keywords: Di-Methyl Ether (DME), SI Engine, LPG and DME Blend, Euro IV Emission, Nitrogen Oxides (NOx), LPG Kit
