Abstract: A homogeneous charge compression ignition engine that prevents knocking and misfires when changing output and when the load or air-fuel ratio changes due to one reason or another when operating under a predetermined condition. A controller determines whether or not the air-fuel ratio is changing in such a manner that there is a possibility of knocking or misfires occurring by using a map defining a range, in which stable homogeneous charge compression ignition operation is enabled, in relation with the air-fuel ratio and the intake air temperature. When the air-fuel ratio indicates that there is a possibility of knocking or misfires occurring, the controller controls an intake air temperature adjustor to adjust the intake air temperature based on the map.

Abstract: A homogeneous charge compression ignition engine for preventing knocking or misfires even if the air-fuel ratio deviates from a target value. The controller determines the possibility of misfires occurring due to changes in the air-fuel ratio based on a map showing the relationship of the air-fuel ratio and the timing at which the exhaust valve closes (EVC) when stable homogeneous charge compression ignition is enabled. When there is a possibility of misfires occurring, the controller retards the EVC. When there is a possibility of knocking occurring due to changes in the air-fuel ratio, the controller uses a map to advance the EVC.

Abstract: The present invention provides a fuel-injection control device for a diesel engine which uses a combination of a common-rail-type fuel-injection pump and an EGR control for exhaust gas purification.In a fuel-injection control device for a diesel engine having a common-rail-type fuel-injection pump comprising a means for controlling fuel-injection pressure according to engine load and an EGR control means for adjusting the EGR ratio according to engine load, where the EGR can be reduced to zero, the means for controlling fuel-injection pressure includes a correcting function to correct the fuel-injection pressure in response to the EGR ratio.

Abstract: A method of injecting viscous fluid into bread or confectionery is provided. Viscous fluid is drawn by a piston from a hopper through a 3-port valve into the chamber of a first piston cylinder, and after changing the position of the valve the viscous fluid is extruded through a tube and a reciprocally movable nozzle into a product while the nozzle is being retracted.According to the present invention, the relation between the time of retraction of an injection nozzle from bread or confectionery and the stroke and time of extrusion by a piston is adjusted, so that the position, amount, and length of the viscous fluid charged in the product can be freely varied.
