Abstract
The Earth, a complex and interconnected system, faces an imminent threat from climate change, exacerbated by escalating carbon emissions. The Philippines addressed air quality concerns with the Clean Air Act of 1999, emphasizing mobile sources like vehicles. This paper proposed a catalytic converter prototype incorporating zeolite to assess its efficiency in reducing carbon emissions. Employing an experimental approach, the study utilizes t-tests as a statistical tool to compare carbon emissions between vehicles with and without the zeolite-based catalytic converter and value analysis and value engineering to optimize the production process and reduce costs. Based on the obtained results, "Z-Lite'' is a profitable alternative exhaust filter for diesel engines, showcasing its potential to reduce carbon emissions significantly. The statistical analysis, yielding a low p-value, supports the hypothesis that zeolite filters effectively reduce carbon emissions. With over 100 emission centers in the Philippines, the marketability of Z-Lite in Marikina City underscores its practicality in addressing environmental concerns and promoting sustainable practices in the transportation industry. The integration of value analysis and value engineering ensures that it is both environmentally friendly and affordable, making it a promising and sustainable choice for mitigating the environmental impact of diesel engine emissions.
