Petrol and diesel engine design technologies eyeing 2020 and beyond

The developing countries are planning and proposing several stringent regulations to achieve air quality standards and vehicle fuel economy standards and these regulations are pushing the automotive industries to engage in severe competition in terms of technological development beyond 2020. Urea-selective catalytic reduction (SCR) and NO_x storage reduction catalyst systems are expected to be used for the reduction of NO_x emission. The premixed charge compression ignition (PCCI or HCCI) combustion will be used to reduce particulate matter and NO_x emissions to low levels thus reducing the dependence on emission aftertreatment. The petrol as well as the diesel-powered vehicles will develop the technologies regarding combustion, aftertreatment and fuel. The use of advanced lithium-ion batteries for hybridizing will improve the fuel economy. Biofuels including bioethanol, biodiesel and biomass-to-liquid (BTL) mixed in any ratio will reduce oil dependence.
