More Information
Summary:A control device for an engine in which partial compression-ignition combustion including spark ignition combustion performed by combusting a portion of mixture gas inside a cylinder by spark ignition followed by compression ignition combustion performed by causing the rest of the mixture gas inside the cylinder to self-ignite is executed within at least a part of an operating range of the engine, is provided. The device includes a detector configured to detect a parameter related to noise caused by the combustion inside the cylinder, and a combustion controller configured to control the combustion inside the cylinder during the partial compression-ignition combustion based on the detected parameter of the detector and a reference value defined as an upper limit regarding the noise. The reference value is adapted to increase as a vehicle speed, an engine speed, and/or an engine load increases.
