Vehicular Emission Control Strategies for the Capital City of Delhi

In this paper, the contribution of the various means for controlling harmful automobile emissions has been discussed. The benefits, which could accrue by use of the catalytic converter and other engine design improvements, including alternative technologies, are considered so that appropriate emission control technologies could be adapted in the near and long term future. Catalytic converter is a device with proven technology and hence it is included with greater emphasis. The oxidation type catalytic converter provides positive atmosphere to oxidize carbon monoxide and hydrocarbons along with restricting the conversion of NO_x [1]*. Other technologies such as exhaust gas recirculation, fuel cell, alternative fuels and electric/hybrid vehicular technology have also been discussed in brief.
