摘要： An engine control device including: a turbocharger; an EGR device that includes an EGR passage, an EGR valve, and an EGR cooler; and a PCM that, based on an operation state of an engine, controls the EGR valve to adjust an EGR rate that is a ratio of an EGR gas amount to a total amount of gas introduced to a cylinder of the engine. The PCM controls the EGR valve such that, in a high load range and a medium load range for the engine, the EGR device recirculates the EGR gas into an intake passage; and controls the EGR valve such that an EGR rate in the high load range is lower than an EGR rate in the medium load range at a same engine speed.

摘要： Provided is a control device of an engine that can certainly suppress and avoid pre-ignition. A control device of an engine is an engine control device for controlling the behavior of fuel that is directly injected into a combustion chamber of a cylinder by a tumble flow, and it has an injector that directly injects the fuel into the combustion chamber, an intake port that generates the tumble flow in the combustion chamber, and an ECU that injects the fuel from the injector at a plurality of injection timings including an intake-stroke-early-half injection timing that is set at an early half of the intake stroke of the cylinder, when an operating state of the engine is in a high-load, low-rotation range.

摘要： An intake device of an engine comprises an intercooler, an intake passage including a downstream-side intake passage, and an EGR passage recirculating exhaust gas to the downstream-side intake passage. An intake-air supply opening having an opening area smaller than an area of a downstream-side face of an intercooler core is provided at a downstream side wall of a chamber. The downstream-side intake passage includes an extension passage portion extending upwardly along the downstream side wall. The intake-air supply opening includes an upper edge portion which separates the intake air flowing from an inside wall face of the extension passage portion and forms flowing main streams of the intake air inside the extension passage portion. EGR introduction ports are arranged at positions capable of supplying the EGR gas toward the flowing main streams.
