Vehicle pollution is the introduction of harmful material into the environment by motor vehicles. Pollutants such as Carbon monoxide, Hydrogen, Nitrogen Oxide, particulate matter, Ammonia and Sulphur Dioxide are present in the vehicular emissions. Vehicular pollution leads to global warming, poor air quality, smog and acid rain and affects health, international reputation and tourism. Thus, control of vehicular pollution is essential. Our services include quantifying the emissions from vehicles in both static and transient conditions. Real-time vehicular emission characteristics using Portable Emission Measurement Systems (PEMS) are also provided.
