AI Technical Summary

Technical Problem

In low-temperature environments, ventilation system ducts are prone to freezing, leading to blockages, affecting the pressure balance in the crankshaft cavity, causing a decline in engine performance, and potentially damaging engine components, increasing maintenance costs and safety hazards.

Method used

A temperature sensor and a heating device are installed in the first ventilation duct of the ventilation system. The temperature sensor detects the air temperature inside the duct. When the temperature is low, the heating device is activated to heat the duct wall and the internal air, reducing the risk of air condensation and ensuring the smooth operation of the ventilation system.

Benefits of technology

It effectively prevents ventilation system blockage, maintains stable pressure in the crankcase, reduces the risk of engine performance degradation, component damage and maintenance costs, and improves engine and vehicle safety.

Abstract

This application relates to an engine system and a vehicle. The engine system includes an engine, an intake system, a ventilation system, and an exhaust system. The engine includes a cylinder block and a crankcase. The cylinder block encloses a combustion chamber, and the crankcase is located within the combustion chamber. The combustion chamber communicates with the crankshaft cavity of the crankcase through piston ring clearance. The intake system communicates with an intake port, and the exhaust system communicates with an exhaust port. The ventilation system includes at least a first ventilation duct and a temperature sensor and a heating device installed on the first ventilation duct. The temperature sensor can detect the temperature of the air inside the first ventilation duct, and the heating device can heat the duct wall and the air inside the first ventilation duct, reducing the risk of air condensation on the duct wall, ensuring the smooth flow of the ventilation system, maintaining stable pressure inside the crankcase, and reducing the risks of engine performance degradation, engine component damage, increased engine system maintenance costs, and engine safety hazards.
