TEMPERATURE RAISING MECHANISM FOR BLOW-BY GAS TREATMENT DEVICE AND ENGINE PROVIDED WITH TEMPERATURE RAISING MECHANISM FOR BLOW-BY GAS TREATMENT DEVICE

A temperature raising mechanism for a blow-by gas treatment device which can suppress freezing of moisture contained in blow-by gas at a low temperature and an engine including the temperature raising mechanism for the blow-by gas treatment device are provided. [0002] A temperature raising mechanism 800 for a blow-by gas treatment device has a head cover 4 assembled to a cylinder head of an engine, a blow-by gas treatment device 100 which is disposed in the head cover 4 and treats the blow-by gas, and heating means 600 which is fixed to an outer surface 703 of the head cover 4 and generates heat. The blow-by gas treatment device 100 has a partition wall part 200 which is fixed to the head cover 4 and partitions an inside of the head cover 4 into a plurality of regions, and a separating portion 330 which is provided in the partition wall part 200 and separates the blow-by gas into oil and gas. The head cover 4 has a heat conducting portion 700 which is in contact with the partition wall part 200 and conducts the heat generated by the heating means 600 to the separating portion 330.
