AI Technical Summary

Technical Problem

The outlet pipe of the crankcase oil and gas separation mechanism is prone to steam freezing at low temperatures, resulting in failures such as the dipstick disengagement, the crankshaft oil seal disengagement, and the supercharger damage.

Method used

Design a crankshaft box oil and gas separation and ventilation system. By connecting the gas pipeline of the oil and gas separation mechanism to the air intake system, the air intake system is set on the water -cooled mid -cooler. Use thermal conductivity to keep the internal temperature of the air pipe road above the freezing point to prevent steam from freezing.

Benefits of technology

Effectively prevent the steam icing in the trachea in the tracheon, avoid failure at low temperatures, and ensure the pressure balance of the engine under different load conditions.

Abstract

The utility model provides a crankcase oil-gas separation and ventilation system and an engine assembly. The crankcase oil-gas separation and ventilation system comprises an air inlet system, a water-cooling intercooler and an oil-gas separation mechanism arranged on a crankcase. The air inlet system is arranged on the water-cooling intercooler; the oil-gas separation mechanism is provided with a crankcase blow-by inlet connected with a crankcase and a gas outlet pipeline communicated with the gas inlet system, and gas separated by the oil-gas separation mechanism enters the gas inlet system through the gas outlet pipeline; a crankcase air supplementing pipe of the crankcase communicates with the air inlet system on the upstream of the air outlet pipeline connecting position. According to the oil-gas separation and ventilation system of the crankcase, steam in the gas outlet pipeline of the oil-gas separation mechanism cannot be frozen, and the problem that the steam in the gas outlet pipeline of the oil-gas separation mechanism of the crankcase is prone to freezing at low temperature can be solved.
