Heat accumulation inside the closed chamber of CVT resulted in an inefficient transmission of power and caused belt slippage and wear. This reduced the efficiency of power transmission to the subsequent stages of the driveline. Cooling fins were incorporated for effective dissipation of heat generated due to the continuous dynamic contact between the rubber belt and the pulleys of the CVT. This increased the overall efficiency of the drivetrain.

The emissions in automobiles include volatile organic compounds, particulate matter, nitrogen oxides, carbon monoxide, sulphur dioxide, and greenhouse gases. Incomplete combustion of the fuel produces particulate matter (soot), which are solid carbon particles that are hazardous to our environment. In order to reduce these emissions, catalytic converters are used.
Catalytic converters change harmful substances in a car’s exhaust gases into less harmful substances like carbon dioxide and water vapor by means of chemical reactions. It is usually filled with a honeycomb structure onto which a coating is applied that contains a catalyst; the substance that creates a reaction with the exhaust gasses; changing their chemical structure. We used catalytic converter using a catalyst made of Cu/ZnO/Al2O3.
