Abstract
The present technology provides methods and systems for reducing ice buildup in a closed engine breather system. The systems comprise an air inlet duct, a compressor wheel and a compressor cover. The compressor cover comprises a breather gas port. The breather gas port is placed in the compressor cover at a location within close proximity to the leading edge of the compressor wheel so that the compressor wheel is capable of removing ice that accumulates at the breather gas port. The present technology also provides methods that include providing an air inlet duct, a compressor wheel, and a compressor cover with a breather gas port in the compressor cover. In this manner the compressor wheel can grind or shave off ice that accumulates at the breather gas port.
