  • Publication number: 20240151190
    Abstract: A control device for controlling an engine includes main-chamber injecting means (1,3) that supplies a main chamber (8) with fuel; sub-chamber injecting means (2) that supplies a sub chamber (5) with fuel after the main chamber injecting means (1,3) supplies the fuel; estimating means (21) that estimates a degree of knocking serving as indices of an intensity of the knocking and an occurrence frequency of the knocking; and fuel controlling means (22) that carries out, when the degree (N) of the knocking is a first predetermined value (N1) or more, fuel control that reduces a sub-chamber fuel amount representing an amount of fuel supplied by the sub-chamber injecting means (2). By reducing the sub-chamber fuel amount in this manner, the occurrence of knocking can be suppressed, so that the combustion state of a divided-combustion-chamber engine can be enhanced.

  • Patent number: 11708786
    Abstract: An auxiliary chamber type internal combustion engine includes a main chamber, an auxiliary chamber, a plurality of connecting passages connecting the main chamber with the auxiliary chamber, and an ignition plug configured to ignite a mixture introduced into the auxiliary chamber. The plurality of connecting passages include a first connecting passage having a first injection port and a second connecting passage having a second injection port. A flame generated in the auxiliary chamber is injected into the main chamber through the first and second injection ports. The first injection port is configured such that the flame propagates along a ridge line at which the plurality of inclined surfaces of the cylinder head intersect. The second connecting passage extends in a direction oriented to the piston with respect to the first connecting passage when viewed from a direction perpendicular to the cylinder axial direction.

  • Patent number: 7831156
    Abstract: An image forming apparatus includes a sensor, a notification unit, and a controller. The sensor detects a supply-end condition of consumable supplies. The notification unit notifies a message based on the supply-end condition detected by the sensor, and provides an operation key used for setting a condition for the image forming apparatus. The notification unit includes a print-stop setting and a print-continue setting, settable for a consumable supply and used when a printing operation is suspended due to an occurrence of the supply-end condition. The controller suspends the printing operation based on the print-stop setting and continues the suspended printing operation based on the print-continue setting.
