The majority of the environmental pollution is from the two-wheeler automobiles due to their large number. A study on nano-particle reveals that the ratio of surface area of nano-particle to the volume of the nano-particle is inversely proportional to the radius of the nano-particle. So, on decreasing the radius, this ratio is increased leading to an increased rate of reaction and the concentration of the pollutants is decreased. To achieve this objective, an innovative design of catalytic converter for two-wheeler automobiles is proposed using nano-particle as a catalyst. This research paper basically deals with the behavioral modeling and simulation of two stroke engine with developed catalytic convertor. The basic idea of behavioral modeling starts from analyzing the practical behavior of two stroke engine with designed catalytic convertor, and then approximating obtained behavior in terms of mathematical equations. These obtained equations actually represent behavior of concern system. Once mathematical equations are obtained, next stage is to implementation of these equations in Simulink platform. The last process is the validation check by the simulation of developed model. Keywords: Automobiles; catalytic converter; modeling; nano-particle; simulation 1. Introduction Nanotechnology is one of the most emerging fields of science today due to its manifold applications and utility. Nano-particles are used for a variety of purposes from medical to scientific. Actually, when the size of a particle is reduced to the extent of about 10 -9 m, it is called nano-particle. The small size of the particle makes it highly reactive Therefore; the nano-particles are also used to treat a variety of ailments and diseases like cancer. The major contributor of environmental pollution is the exhaust emissions from the tail pipe of automobiles. A complete re-design may not be as lucrative as the modification of the exhaust tailpipe arrangement. The exhaust emissions can be treated by nano-particles before ejecting them to atmosphere [1]. The exhaust emissions mainly contain carbon di-oxide which causes global warming and CO which is very harmful to human health and welfare [2]. Unburnt hydrocarbons are present in exhaust emission due to incomplete combustion. The level of unburned hydrocarbons is
