Claims

[Scope of utility model registration request]

There is a filter made of heat-resistant material that is installed in the middle of the exhaust pipe that distributes the exhaust gas discharged from the engine and can freely collect carbon particles contained in the exhaust gas. A heater for combustion, an upstream sensor that detects a pressure state on the upstream side of the filter, and a downstream sensor that detects a pressure state on the downstream side of the filter;
It consists of a load sensor that detects the load state of the engine, and a controller that inputs signals from each sensor and controls energization to the heater based on each signal, and this controller is equipped with a storage means, If it is determined that it is necessary to incinerate the carbon particles attached to the filter based on the signals from the upstream and downstream sensors, this fact will be memorized, and after the memorization, when the engine load becomes smaller, , an exhaust purification device that energizes the heater based on this memory.
