I have seen an article from the BC Diesel portal. We are unaware of the reasons that cause the engine damage. The overheating of the diesel particulate filter cause the engine damage. Now the DPF is available to the small and medium duty diesel too, but itís over-usage cause bad effect to the engine. I was surprised to see the article from the site:https://www.bcdiesel.ca/en/carb-admi...-engine-damage as the CARB admits that the major reason behind the engine failure is due to the excessive heating effects of the DPF (quoted with statements).
