Document Type and Number:
Japanese Patent JP7038573
Kind Code:
B2
Abstract:
This engine system is provided with: an engine; an intake passage; an exhaust passage; an electronic throttle device; an EGR device including an EGR valve; a fresh-air flow device including a fresh-air inflow valve; and an ECU. The ECU, in order to throttle intake air to the engine during deceleration of the engine, causes the electronic throttle device to be closed from an open valve state to a predetermined deceleration opening while causing the EGR valve to become closed to shut off introduction of EGR gas into the intake passage, and, in order to introduce fresh air into the intake passage (intake manifold) downstream of the electronic throttle device, causes the fresh-air inflow valve to become opened from the closed valve state at a timing delayed by a predetermined period from the timing of closing the electronic throttle device.
