Analysis of opacity levels in diesel engines with mechanical and electronic fuel injection (CRDI) systems

Abstract

The research compares two Diesel engines with different injection systems to determine their environmental impact. Information was gathered from various sources, including NTE INEN, to assess emission control. The technical specifications of the engines were analyzed, and opacity tests were conducted on a Hino FG and a Mazda BT-50 CRDI. Additionally, a Chevrolet D-max 3.0 vehicle was included to broaden the discussion on factors affecting opacity. These vehicles were manufactured after 2000 when regulations set the maximum opacity limit at 50%. Results show that the CRDI system vehicle emits significantly fewer pollutants, with an opacity of 8.4%, compared to the other engine, which recorded an opacity of 45.3%, and the additional vehicle with an opacity of 6.1%. This demonstrates that the CRDI system is more environmentally friendly according to current regulations. In conclusion, the research highlights the importance of Diesel injection technology in reducing emissions and protecting the environment.
