STUDY OF COLD STARTING PROBLEM IN SCOOTY PEP+

In some vehicles there are problem of cold starting and overheating. For the experiment we have selected Scooty pep+. In Scooty pep+ it have 88-CC single cylinder air cooled petrol engine. The major problem in this model is, 1. Cold Starting 2. Transmission system produce heat. Due to these problems a good Scooty pep+ cannot exist in market. In the winter season the vehicle can’t start easily. Due to cold starting problem, the vehicle emits more NOx, hydrocarbon (HC) and carbon monoxides (CO). Which can reduce the efficiency and life of vehicle. In this project we will solve the problem of cold starting in vehicle by modification of engine. For the problem of the overheat produce, we will do the material coating on the piston by the material which have less thermal co-efficient so that heat cannot easily dissipate to the transmission. To increase the combustion characteristics we will use different spark plug with different spark intensity.
