The air pollution is increasing at an alarming rate now a day mainly due to emissions coming out of automotive vehicles. The exhaust emissions gases are hazardous to human health. The increased number of vehicles on road will make the scenario even worse. In order to control the pollution level, the regulatory bodies are now implementing stringent emission norms. In India, the regulatory authorities has framed the transition of BS IV to BS VI emission norms in 2020 by skipping the BS V emission norms which makes the automotive industries to work on more advanced fuel management technologies. It is more tedious to control the tail pipe emissions beyond BS IV emission norms with the conventional carburetor system since it is operating on open loop system. It is evident that in order to meet the stringent emission norms we need to have a closed loop system which controls the Air Fuel Ratio (AFR) close to stoichiometric to increase the conversion efficiency of the catalytic converter.

The automotive industry in world is facing the problem of reduction of emissions coming out of the engine. Also, the stringent emission norms imposed by the regulating body for transition from BS IV to BS VI urges the auto makers to concentrate on new technologies to reduce the emissions. One of the major emissions coming out of the diesel engine is oxides of nitrogen (NOx) which is detrimental to human health. This NOx emission is formed when the combustion temperature of engine exceeds the threshold limit. There are several methods available to reduce these NOx emissions formed in-cylinder. Exhaust Gas Recirculation (EGR) is one such system, which reduces the NOx emission formed inside the engine by supplying a portion of the exhaust gases. By re-circulating exhaust gases, the air admitted to the engine is diluted. Further, due to the high latent heat of vaporization of water, water vapor tends to absorb more amount of heat that is generated during combustion.

Commercial transportation is the key pillar of any growing economy. Light and Small commercial vehicles are increasing every day to cater the logistics demand, but there is always a gap between customer’s actual and desired operational efficiency. This is because of lack of organized fleet and efficient fleet operation. The major requirement of fleet owners is timely delivery, high productivity, downtime reduction, real time tracking, etc., Automakers are now providing fleet management application in modern LCV & SCV to satisfy the fleet operator requirement. However, any feature malfunction, consignment mismatch, wrong notification, missed alerts, etc., can incur huge loss to fleet operator and disrupt the entire supply chain. Hence it is very critical to extensively validate the telematics features in fleet management application. This paper explains the approach for exhaustive validation strategy of fleet management applications (B2B) from end user perspective.
