| Diesel engine has been used for heavy tasks in many sectors such as agriculture, construction, industrial and public transportation for more than 50 years because its durability, high torque capacity, and fuel efficiency. One of the most difficult challenges for diesel engine designers is the formation of particulate matters (PM) during its combustion process which is harmful for environment and health. Diesel Particulate Filter (DPF) is used to prevent this PM from being exposed to the atmosphere. The purpose of this experiment is to know the Cordierite and Silicon Carbide (SiC) DPF performances in reducing the PM emission and other exhaust gas emissions that formed from diesel engine combustion process. This experiment is conducted in two stages which are the fuel testing to determine the fuel specification; and engine emissions testing with Mitsubishi Fuso 3.0 L engine that has been equipped with DPF. Also, the engine emissions testing is conducted with 3 different fuels (JIS #2, B20, B100), 3 different engine loads (100 Nm, 200 Nm, full load) and presence or absence of Diesel Oxidation Catalyst (DOC). In this experiment, it was found that both of DPF types have an excellent performance in reducing the concentration of PM as much as 99,9% from the total amount produced by engine diesel. However, SiC DPF has a better performance than Cordierite DPF in reducing PM. Also, it was found that the fuel type, engine load and the usage of DOC affect the emissions that have been produced by the engine diesel while using DPF. |
