A control device for controlling an engine includes main-chamber injecting means () that supplies a main chamber () with fuel; sub-chamber injecting means () that supplies a sub chamber () with fuel after the main chamber injecting means () supplies the fuel; estimating means () 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 () that carries out, when the degree (N) of the knocking is a first predetermined value (N) or more, fuel control that reduces a sub-chamber fuel amount representing an amount of fuel supplied by the sub-chamber injecting means (). 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.

Engine control device

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.

Auxiliary chamber type internal combustion engine

An apparatus that uses plural kinds of consumable items different from each other, the apparatus including a consumption status detecting device to detect a respective consumption status for each of the plural kinds of the consumable items, a memory to store a plurality of settings for each of the plural kinds of the consumable items, each of the settings including presence or non-presence of information output, and an output device to output the consumption status detected by the consumption status detecting unit, according to the setting of the presence or the non-presence of information output stored in the memory.

Apparatus and output setting method of consumed status of consumable items of the apparatus

An apparatus in which a plurality of consumable items are loadable to the apparatus. The apparatus includes a consumption status detecting unit to detect a respective consumption status of each of the consumable items, a consumption information output setting unit to set whether an exchange message for each of the consumable items is to be output, and a consumable item information output unit to output the exchange message, which is indicative of an exchange time of the respective consumable item, based on the respective consumption statuses detected by the consumption status detecting unit and the setting of the consumption information output setting unit.

Image forming apparatus and output setting method of consumed status of consumable items of the image forming apparatus

An apparatus, method, system, computer program and product each capable of storing supply information of a printer supply of an image forming device, and generating a supply information list including the supply information to be printed on a recording sheet according to print settings information.

Printing supply information of an image forming apparatus

An image forming apparatus in which a first consumable item and a second consumable item are loadable to the image forming apparatus, includes a consumption status detector that detects an end status and a near-end status for each of the first and second consumable items, wherein the end status is a consumption status in which the consumable item must be exchanged immediately and the near-end status is a consumption status in which the consumable item must be exchanged in the near future; a consumption information output setting unit that sets settings indicating whether to output information for each of the end status and the near-end status of the first and second consumable items detected by the consumption status detector; and a consumption information output unit configured to output the information for each of the end status and the near-end status of the first and second consumable items based on the settings set by the consumption information output setting unit and a detection result of the consumption status of the first and second consumption items.

An image forming apparatus including a plurality of consumable items. The apparatus includes a consumption status detecting unit that detects a respective consumption status of each of the consumable items; a consumption information output setting unit that sets presence or non-presence of information output for each of the consumption statuses detected by the consumption status detecting unit; and a consumable item information output unit that outputs information on the consumable items based on the respective consumption statuses detected by the consumption status detecting unit and the setting of the presence or the non-presence of information output set by the consumption information output setting unit.

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.

Image forming apparatus having enhanced management for consumable-supplies

An image forming apparatus which uses a consumable item is disclosed. The image forming apparatus includes a consumed status detecting unit which detects a value of the consumed status of the consumable item, a determining unit which determines whether to output an exchange message of the consumable item by comparing the value of the consumed status of the consumable item detected by the consumed status detecting unit with a predetermined value, an exchange message output setting unit which sets presence or non-presence of an output of the exchange message, and a consumed status output setting unit which sets presence or non-presence of an output of the consumed status of the consumable item detected by the consumed status detecting unit.

The color toner application level is flexibly adjusted to save the toner consumption by lowering the developing bias voltage value while color balance is maintained by adjusting gamma characteristics. The toner save mode is invoked based upon the detection of substantially unequal toner consumption among color components.

Toner save method and system for image duplicating devices

An image forming apparatus with a scanner and a method of controlling it are disclosed. Different kinds of images are combined by a simple and rapid procedure. When the scanner is connected to the apparatus, various kinds of functions available are used in an easy-to-understand and convenient way. Also disclosed are a printer with a scanner which can be readily loaded with handwritten characters, types, letterings and so forth to convert them to a font. Further, the image forming apparatus with a scanner, the method of controlling it, and the printer with a scanner are capable of easily filling a document to be prepared by the operator with a desired fill pattern, e.g., a handwritten pattern.
