Abstract

The system comprises: a temperature sensor located on the engine oil underpan; the pressure sensor and temperature sensor located at the positive crankcase ventilation system outlet. The gas mixture outputted from the positive crankcase ventilation system is sent to the condenser via pipe; at the outlet of the condenser there is a temperature sensor located; the outlet of the condenser is connected to the inlet of the collection bottle via pipe. In the invention, a collection bottle is used to collect the motor oil condensed from the gas mixture by the condenser; said motor oil is separated and analyzed to get the actual quantity of the carried oil.

Description

technical field [0001] The invention relates to an automobile experiment system, in particular to an automobile engine crankcase ventilation system oil carrying amount experiment system and an experiment method. Background technique [0002] With the increasingly stringent emission regulations for cars, closed crankcase ventilation systems have been adopted for car engines. The use of a closed crankcase ventilation system will bring the oil-gas mixture in the crankcase into the combustion chamber to varying degrees due to the different separation effects of the crankcase ventilation system, which will affect the engine exhaust emission indicators, and the more serious situation may be cause engine damage. Contents of the invention [0003] The object of the present invention is to provide an engine crankcase ventilation system engine oil carryover experimental system, which is used to truly and reliably evaluate the separation effect of the crankcase ventilation system an...
