Most diesel engines, including Hino trucks, are equipped with a DPF as part of their emissions control system. Its function is to trap soot and particulates in the exhaust system, effectively reducing harmful emissions. However, despite its environmental benefits, the DPF can bring certain operational drawbacks. These include frequent clogging, higher fuel consumption, and costly maintenance sessions to ensure it functions correctly.
