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.
