Abstract
The Indian emissions legislation introduced in April 2000 for 2-wheelers has resulted in the widespread use of exhaust catalysts on 2-stroke powered vehicles. There has been debate over the effectiveness of this emissions solution compared to alternatives such as the 4-stroke engine. This paper describes a durability programme using 2-stroke scooters fitted with exhaust catalysts and driven on Indian roads. The emissions were monitored at regular intervals over 30,000 km. These vehicles were found to comply with the India 2000 emissions limits throughout the 30,000 km. The emissions performance of these catalysts were then compared over the Indian Driving Cycle (IDC) on a common vehicle, and by using a newly developed light-off test, to engine bench aged catalysts. All the catalysts were subsequently analysed for thermal deterioration and for concentration of chemical impurities in order to compare the chemical and physical effects of the different types of ageing.
