エンジン暖機システム
Document Type and Number:
Japanese Patent JP6966912
Kind Code:
B2
Abstract:
To more efficiently warm up an engine.SOLUTION: An engine warm-up system 100 includes: an intake flow passage 18; an electric supercharger 22; an exhaust flow passage 20; an EGR flow passage 33; an exhaust control valve 32 for opening/closing the exhaust flow passage; an EGR valve 35 for opening/closing the EGR flow passage; an intake valve 12 and an exhaust valve 13 for an engine 1; an intake/exhaust valve control section 114 for performing opening control of the intake valve and the exhaust valve when the engine is stopped; an electric supercharger control section 128 for driving the electric supercharger when a predetermined engine warming-up execution condition is satisfied; and valve control sections 120, 122 for controlling the exhaust control valve and the EGR valve. The valve control sections close the exhaust control valve and the EGR valve when the engine warming-up execution condition is satisfied, and controls the EGR valve so as to drive the electric supercharger in a predetermined driving region when a predetermined engine warming-up circulation condition is satisfied.SELECTED DRAWING: Figure 1
