Claims

[Scope of utility model registration request]

An internal combustion engine body formed with a cylinder, an intake pipe formed with an intake passage communicating with the intake port of the cylinder, an exhaust pipe formed with an exhaust passage communicating with the exhaust port of the cylinder, an exhaust passage and an intake passage. In an internal combustion engine equipped with an EGR valve that is interposed between the EGR valve and the EGR valve that controls the flow of a part of exhaust gas into the intake passage, the intake pipe is formed with a heating outward path and a heating return path substantially parallel to the intake passage; The inlet of the heating return path is connected to the exhaust passage, and the exit of the heating return path is connected to the EGR valve. When the EGR valve is closed, the exhaust gas that has passed through the heating outward path and the heating return path is returned to the exhaust passage, and the EGR
An internal combustion engine characterized in that when a valve is open, exhaust gas that has passed through a heating outward path and a heating return path is allowed to flow into an intake passage.
