Document Type and Number:
Japanese Patent JP2019135380
Kind Code:
A
Abstract:
To provide a control device of an oil pump which can properly reduce deposits accumulated in a compressor when the compressor efficiency of a supercharger is lowered.SOLUTION: An internal combustion engine 10 comprises: a supercharger 24 having a compressor 24C at an intake passage 20; a blowby gas passage for introducing a blowby gas in a crank case 19 to the intake passage 20 at an upstream side rather than the compressor 24C; an oil pump 80 for supplying a lubricant into the cam case 39, and changeable in a discharge amount; and a lubricant passage 70 which makes the lubricant supplied into the cam case 39 fall down into the crank case 19, and in which an opening part at the crank case 19 side is located above a crankshaft 18. A control device 100 performs processing for increasing the discharge amount of the oil pump 80 in a state that the compressor efficiency of the supercharger 24 is not higher than a prescribed value compared with the case that the compressor efficiency is not in a state not higher than the prescribed value.SELECTED DRAWING: Figure 1
