Abstract

The invention aims to provide a ventilation test device of a crankcase so as to shorten the period and reduce the cost in the development process of a ventilation system of an engine crankcase. The ventilation test device of the crankcase comprises a frame-type body formed by connecting coaming plates at the periphery; and two ends of the body are respectively provided with an air inlet and an air outlet. The ventilation test device is characterized in that a plurality of sliding plates are movably installed on side walls of two sides of the body. Through the slidable sliding plates, the ventilation test device of the crankcase can assemble different labyrinths simply and quickly and realize different ventilation schemes by utilizing a set of crankcase ventilation test device instead of a plurality of valve chamber cover caps for testing, therefore, the period can be shortened and the cost can be reduced in the development process of an engine.

Description

technical field [0001] The invention belongs to the technical field of engine testing, and in particular relates to a crankcase ventilation testing device during engine testing and development. Background technique [0002] With the increase of public awareness of environmental protection, the country's automobile emission regulations are becoming more and more stringent, especially for the emission of hydrocarbons. The crankcase ventilation system of the current automobile engine is equipped with a labyrinth for recovering oil and gas, and a suitable labyrinth scheme is very important for the control of hydrocarbon emissions in the crankcase ventilation system. In the process of engine development, generally two or more maze methods need to be verified. However, the labyrinth is generally integrated on the valve chamber cover, which means that a variety of valve chamber covers are required for experimental verification. The valve cover is usually made of rapid prototyping...
