“…Simulation and experiment results show that when the DPF wall temperature is 800 • C or higher, filter clogging can be avoided so as to achieve continuous regeneration [24,25]. Further studies on regeneration temperature prediction show that the root mean-square temperature error using the diesel oxidation catalyst-catalyzed particulate filter estimator was within 3.2 • C compared to the experimental data [26,27].…”

In the application of DPFs (diesel particulate filters), temperature prediction and control technology during the regeneration phase has always been a great challenge, which directly affects the safety and performance of diesel vehicles. In this study, based on theoretical analysis and sample gas bench test results, a one-dimensional simulation model is built with GT-POWER software. The effects of soot loading quantity and oxygen concentration on regeneration temperature performance are studied. Simulation results show that, when the soot loading quantity exceeds 46 g (12.7 g/L), the maximum temperature inside DPF during the regeneration phase would be higher than 800 °C, and the risk of burning crack would be high. When the oxygen concentration in the exhaust gas is low (lower than 7%), the fuel injected into exhaust gas fails to give off enough heat, and the exhaust gas temperature fails to reach the target regeneration temperature, hydrocarbon emission could be found from the DPF outlet position; when the oxygen concentration in the exhaust gas reaches 7% or above, the DPF inlet temperature could reach the target temperature, accompanied by less hydrocarbon emission. Combined with the simulation results, engine test bench validation was carried out. The results show that the simulation results and test results agree well.

The use of diesel engines in commercial vehicles is still the main choice and the most widely used. The increasing number of commercial vehicles that use diesel engines can pollute the environment and cause noise. In order to reduce exhaust emissions and noise in diesel engines, a particulate filter diesel technology was created which is installed in commercial vehicle diesel engines. This study uses an experimental method. The test was carried out on a Mitsubishi L300 commercial vehicle diesel engine type 4D56 4 cylinder with a cylinder capacity of 2477 cc. The diesel particulate filter technology uses a half honeycomb model made from galvalume plates, with variations in the addition of filters in the form of glass wool of 50 grams, 100 grams, 150 grams, 200 grams, and 250 grams. Testing the exhaust emissions of a diesel engine using a TEN Automotive Equipment Innova 2000 multigas analyzer with a smoketester. Sound noise testing using a sound level meter test tool LT Lutron SL-4001. The test results with the addition of diesel particulate filter technology can reduce exhaust emissions and sound noise. The use of diesel particulate filter technology can reduce exhaust emissions in the form of Particulate Matter (PM) most optimally at the addition of a 100 gram filter with a decrease of 45.9%. The most optimal reduction in noise is the addition of a 50 gram filter with a decrease of 26.5%.
