Title:
BLOW-BY GAS VENTILATOR OF INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2007270723
Kind Code:
A
Abstract:

To restrain the deterioration in lubricating oil, by maximally checking mixing of moisture in blow-by gas in the lubricating oil, by promoting atomization of the blow-by gas, by raising the atmospheric temperature in a crankcase, by heating and introducing a part of fresh air extracted from an intake system into the crankcase.

This internal combustion engine 23 has a blow-by gas reducing device 64. This blow-by gas ventilator of the internal combustion engine is composed of fresh air introducing passages 62 and 63 having the large fresh air introducing space volume for introducing the fresh air into the crankcase from an intake system 48, and fresh air heating means 66 and 68 heating the fresh air introducing passage 62 introducing the fresh air by a high temperature source in the internal combustion engine 23.
