Analysis of Exhaust Gas Emissions from Gasoline Engine-Powered Passenger Vehicles in Nigeria

Abstract

Emissions from vehicles in developing country constitute a large percentage of global emissions. The study involved the analysis of exhaust emissions using a gas analyser. The vehicles studied are mini buses and private vehicles of different model of carswhich constitute about 80% of the vehicles on Nigeria roads. It was established that the main types of exhaust gases from the automobiles were CO2, NO2, CO, and O2. The highest emission of CO2 was found to be 413.13 mg/m3 in the 2007 Peugeot car model. The highest exhaust gas emission of NOx, O2 and CO was discovered in the 1998 Honda passenger car model and recorded as 40.23 mg/m3, 45.41mg/m3 and 192.43 mg/m3 respectively. The study of emissions will spur further studies on more efficient combustor design aimed at minimizing emissions.
