摘要:
In the top face of a piston (6), there is formed a cavity (30) having a bottom surface (32) which slopes downward toward an exhaust side and which includes a raised part (32a) extending from near the center of the bottom surface to an intake-side wall surface. The cavity guides fuel spray (15) which has been injected by an injector (12) and passed by an electrode part (14a) of a spark plug (14), to arrive near the electrode part of the spark plug again in the form of an air-fuel mixture (15a).

An in-cylinder injection type internal combustion engine, which includes a main fuel injection control unit that drives a fuel injector to inject fuel directly into a combustion chamber, is provided so that premixed combustion or stratified charge combustion takes place depending upon operating conditions of the engine. The engine further includes an additional fuel injection control unit that drives the fuel injector to inject additional fuel during an expansion stroke after the fuel injector is driven by the main fuel injection control unit, when it is necessary to increase the temperature of a catalyst provided in an exhaust passage for purifying exhaust gas. An exhaust manifold includes an exhaust chamber, in which the exhaust gas remains, and the additional fuel that is left unburned is re-burned in the exhaust chamber.

According to the invention, there is provided a cylinder cleaning device for use with a cleaning fabric supply roll having a cleaning fabric wound thereon. The cleaning fabric is supplied from the supply roll and pressed against the outer surface of a cylinder to clean the outer surface of the cylinder. The device comprises frame means and roll receiving means mounted on the frame means. The outer surface of the supply roll is engaged with and received by the receiving means. The device further comprises roll stabilizing means for stabilizing the supply roll on the receiving means when the supply roll is rotated on the receiving means to supply the cleaning fabric and have a diameter correspondingly decreasing.

A portable electric power source characterized by the fact an electric double layer battery is placed at a stage which follows a cell which generates electricity by receiving sunlight; and in which in order to produce current bit by bit from said electric double layer battery, the current capacity of said electric double layer battery is made smaller than the current capacity of a constant voltage secondary battery of a following stage; and which is further characterized by the fact that a DC--DC convertor is connected to the next stage, so that charging can be carried out at said constant voltage secondary battery even at an electric potential in which the output voltage of said electric double layer battery is lower than the voltage of the constant voltage secondary battery attached to the following stage. The portable electric power source device with attached battery charger of the present invention effectively allows more than 90% of consumer semiconductor devices or appliances typically used in the home to be powered by distribution management. This invention also makes possible long term charging of the electrical power source of vehicles, supplying current and instantaneous pulse voltage, as is needed for automobile ignition.

Among systems configured by connecting a plurality of sequence controllers to one communication line to intercommunicate, many systems has been disclosed which implement fault location and recovery from the faults. In one of these systems, each substation is connected to a circulating communication line via a branch line and switches are respectively disposed on the branch line and on the communication line at both sides of a connecting point of the branch line and the communication line. Further, the communication line can be formed in a loop by a spare line. In another of these systems, an integrated portion of the communication line is formed near the master station, and the communication line is connected to the master station and is configured of one continuous line which goes and backs in sequence between the integrated portion and vicinity of each substation. In that integrated portion, a switch is disposed on each one of two lines, which connect the integrated portion and each substation. Further, a switch is provided on a line which bypasses these two switches. Other systems are a composite of the above systems. Still other systems have automated portions of fault location and fault recovery.
