Some studies on reducing carbon dioxide emission from a CRDI engine with hydrogen and a carbon capture system

The increased use of fossil fuels in the transportation sector has led to an exponential rise of carbon dioxide in the atmosphere. The carbon dioxide (CO2) is the major cause of global warming resulting in climate change and extremeweather conditions. This study explores the ways of reducing the CO2 emission fromthe exhaust of a common rail engine. The reduction in CO2 emissions were achieved by a combination of methods. It includes the use of low carbon biofuels (cedarwood oil (CWO), and winter green oil (WGO)), inductionof zero-carbon, hydrogen in the intake manifold and a zeolite-based after-treatment system. In diesel, CWO and WGO were blended 20% by volume and experiments were conducted at different load conditions. The results shows that 20% blending of winter green oil resulted in maximum CO2 reduction of 20% as compared to diesel. The emissionwas further reduced with the induction of hydrogen along with the after-treatment system. It is seen that a maximum of 54% reduction in CO2 emission could be achieved with the combination for WGO in comparison to diesel without much affecting the other emissions and performance parameters.

This study explores the methods of reducing CO2 emissions from the exhaust of a common rail engine, including the use of low carbon biofuels, induction of zero-carbon hydrogen, and a zeolite-based after-treatment system. Experimental results show that a 20% blend of winter green oil can achieve a maximum reduction of 20% in CO2 emissions, while the combination of winter green oil with hydrogen and the after-treatment system can achieve a maximum reduction of 54% in CO2 emissions without significant impact on other emissions and performance parameters.
