Distance Effects on the Emission of Four Strokes Spark Ignition Gasoline Engine

Abstract

The dusty nature of most Nigerian roads irrespective of season has different negative effects on engineering devices and systems. This nonseasonal phenomenon and its implications on engineering devices and system need to be studied in order to understand the extent of the negative implications. The effect of distance coverage on emission of four stroke spark ignition gasoline engine has been studied extensively. The study was carried out using Minna - Suleja road as case study and 2008 model Peugeot 406 as a test vehicle. Distance of 50 km, 150 km and 200 km were covered with three air filters. The results of the investigation estimated that an air filter get clogged by 23, 38, and 48 grams for 50 km, 150 km and 200 km plies on dusty tarred road. This increased clogging of air filters with distance causes more emissions of hydrocarbons (HC), and carbon monoxide (CO), while on the other hand reduce the formation of carbon dioxide (CO2) and nitric oxide (NO) into the atmosphere. The study therefore recommends that, the inlet of air intake pipes should be incorporated with foam-like dust repel materials. Also, emission directives should be in place after further research using different vehicles categories and fuels
