<P>PROBLEM TO BE SOLVED: To provide an engine starting device including a manually-operated primary pump, delivering an appropriate quantity of starting fuel through a simple operation and obtaining satisfactory engine starting performance. <P>SOLUTION: The starting device includes: the manually-operated primary pump 8 arranged on a fuel introduction path 10a connected to the middle of a fuel-feeding path for sucking and pressure-feeding fuel; and a fixed-quantity fuel chamber 5A for temporarily storing the fuel delivered from the primary pump 8, and supplies a fixed quantity of starting fuel from the fixed-quantity fuel chamber 5A to an intake passage during engine starting. The fixed-quantity fuel chamber 5A has a part of the internal wall displaced elastically to allow the internal capacity to expand and contract within a predetermined range, and is connected to a fuel delivery path 11a that has a manually-operated on-off valve 4a and communicates with the intake passage side. The on-off valve 4a is manually opened in a state that the fixed-quantity fuel chamber 5A expands the internal capacity through the operation of the primary pump 8 and is filled with a predetermined quantity of starting fuel, and thereby the fixed-quantity fuel chamber 5A contracts by elastic contractile force and discharges the fixed quantity of starting fuel. <P>COPYRIGHT: (C)2012,JPO&INPIT |
