Among many environments, the motor vehicle cabin micro-environment has been of public concern. Infact Air pollution more harmful to children in cars than outside. Although commuters typically spend only 1-2hrs per day of their time in vehicles, the emissions from various interior components of motor vehicles as well as emissions from exhaust fumes carried by ventilation supply air are significant sources of harmful air pollutants that could lead to unhealthy human exposure due to their high concentrations inside vehicles’ cabins. This N9 silver ion technology helps significant reduction of microbial & viruses inside the vehicle cabin air. On contact silver will neutralize harmful bacteria on plastic surfaces giving them long lasting freshness and long-term protection. Silver is a natural antimicrobial. That means that microbes-germs can’t survive in the presence of silver ions. Silver ions released from the surface of silver molecules.

The main function of an air conditioning system in a vehicle is to provide the thermal comfort to the occupant at minimum possible energy consumption in all environmental conditions. To ensure the best possible thermal comfort, air conditioning system is optimized on various parameters like heat load, air flow distribution, glass area, trim quality, insulations and cabin leak rate. A minimum cabin leakage is regulatory requirements to ensure the air quality of cabin. Anything above the minimum cabin leak rate ultimately turn into reduced thermal comfort and additional energy consumption. The additional energy consumption to maintain the required thermal comfort in the cabin due to cabin leakage affects the fuel efficiency severely. In the present study, the effect of cabin leakage on fuel efficiency and thermal comfort is studied in details by varying the cabin leakage through mechanical means. The experiments are carried out in normal environmental condition and road condition.
