What does it mean when the carbon loading value of JMC's DPF increases?

The installation of a Diesel Particulate Filter (DPF) is a crucial measure for vehicle diesel engines to comply with emission regulations. The key challenges in the industrialization and practical application of DPFs are to prevent carbon particle clogging under various operating conditions of the diesel engine and to safely and effectively complete the regeneration process. Below is more related information: Methods for calculating carbon loading: 1. A method for calculating the carbon loading of a diesel engine DPF based on pressure drop involves estimating the internal carbon loading using parameters such as the exhaust temperature before and after the DPF. The carbon loading value based on back pressure is calculated through the DPF back pressure model. Among various DPF regeneration technologies, except for continuous regeneration, it is necessary to determine the timing for regeneration. Essentially, determining the regeneration timing involves assessing whether the carbon loading in the particulate filter meets the requirements for regeneration. 2. The most direct method to determine the carbon loading of a DPF is to weigh the DPF when it is unloaded and after loading. However, during the actual operation of the vehicle, it is impractical to frequently dismantle the DPF, making this method unfeasible. Currently, mainstream regeneration control strategies use carbon loading as the direct control parameter to trigger active DPF regeneration. However, during the actual operation of the diesel engine, accurately estimating the carbon loading of the DPF using real-time detectable parameters (such as engine speed, load, exhaust temperature, and DPF pressure drop) and precisely controlling the start and stop of regeneration remain areas for further research.
