Document Type and Number:
Japanese Patent JP2017008721
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To enhance a reduction ratio of blow-by gas in cold start while suppressing influence on an air-fuel ratio.SOLUTION: A blow-by gas control device 1 having a temperature detector 5 for detecting a temperature concerning an internal combustion engine 11, and a PCV valve 2 for controlling a flow rate of flowing blow-by gas includes an air-fuel ratio sensor 6, and control means 3 which can control the PC valve 2. The control means 3 can store the result obtained by the difference between the air-fuel ratio in opening of the PCV valve 2 and the air-fuel ratio in closing of the valve, and can correct an opening of the PCV valve 2 in accordance with the result stored in previous engine operation.SELECTED DRAWING: Figure 1
