Abstract
Abstract The present invention relates to a fuel supplying device for an internal combustion engine having multiple cylinder. The present invention comprises a plurality of fuel injection valves, a fuel pipe through which fuel flows, and a plurality of holder means on the fuel pipe so that the fuel from the fuel pipe is supplied to the holder means. The holder means accommodates the fuel injection valve so that the fuel is supplied to the fuel injection valve, and a start timing of the fuel supplied from the fuel pipe to at least one of the holder means is different from the start timing of the fuel supplied from the fuel pipe to the remaining holder means.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
115 words
A fuel supplying device for an internal combustion engine having multiple cylinder comprising: a plurality of fuel injection valves for injecting fuel toward said cylinder; a fuel pipe through which the fuel flows; and a plurality of holder means mounted on said fuel pipe so that the fuel from said fuel pipe is supplied to said holder means, said holder means accommodating said fuel injection valve so that the fuel is supplied to said fuel injection valve; wherein a start timing if the fuel supplied from said fuel pipe to at least one of said holder means is different from the start timing of the fuel supplied from said fuel pipe to remaining holder means.
Claim 2
Dependent Claim
115 words
A fuel supplying device for an internal combustion engine having multiple cylinder comprising: a plurality of fuel injection valves for injecting fuel toward said cylinder; a fuel pipe through which the fuel flows; and a plurality of holder means mounted on said fuel pipe so that the fuel from said fuel pipe is supplied to said holder means, said holder means accommodating said fuel injection valve so that the fuel is supplied to said fuel injection valve; wherein a start timing if the fuel supplied from said fuel pipe to at least one of said holder means is different from the start timing of the fuel supplied from said fuel pipe to remaining holder means.
Claim 3
Dependent Claim
117 words
A fuel supplying device for an internal combustion engine having multiple cylinder comprising: a plurality of fuel injection valves for injecting fuel toward said cylinder; a fuel pipe through which the fuel flows; and a plurality of holder means mounted on said fuel pipe so that the fuel from said fuel pipe is supplied to said holder means, said holder means accommodating said fuel injection valve so that the fuel is supplied to said fuel injection valve; wherein a distance between a center of at least one of said holder means and a center of said fuel pipe is different from a distance between a center of remaining holder means and a center of said fuel pipe.
Claim 4
Dependent Claim
117 words
A fuel supplying device for an internal combustion engine having multiple cylinder comprising: a plurality of fuel injection valves for injecting fuel toward said cylinder; a fuel pipe through which the fuel flows; and a plurality of holder means mounted on said fuel pipe so that the fuel from said fuel pipe is supplied to said holder means, said holder means accommodating said fuel injection valve so that the fuel is supplied to said fuel injection valve; wherein a distance between a center of at least one of said holder means and a center of said fuel pipe is different from a distance between a center of remaining holder means and a center of said fuel pipe.
Claim 5
Dependent Claim
49 words
A fuel supplying device according to claim 2, wherein a distance between a center of half of said holder means and a center of said fuel pipe is different from a distance between a center of remaining half of said holder means and a center of said fuel pipe.
Claim 6
Dependent Claim
40 words
A fuel supplying device according to claim 2, wherein a distance between a center of each of said holder means and said fuel pipe is different from a distance between a center of remaining holder means and said fuel pipe.
Claim 7
Dependent Claim
97 words
A fuel supplying device for an internal combustion engine having multiple cylinder comprising: a plurality of fuel injection valves for injecting the fuel toward said cylinder; a fuel pipe through which fuel flows; and a plurality of holder means mounted on said fuel pipe for accommodating said fuel injection valve, said holder means having a fuel inlet through which the fuel from said fuel pipe is introduced, and an effective area of said fuel inlet of at least one of said holder means is different from the effective area of said fuel inlet of remaining holder means.
Claim 8
Dependent Claim
97 words
A fuel supplying device for an internal combustion engine having multiple cylinder comprising: a plurality of fuel injection valves for injecting the fuel toward said cylinder; a fuel pipe through which fuel flows; and a plurality of holder means mounted on said fuel pipe for accommodating said fuel injection valve, said holder means having a fuel inlet through which the fuel from said fuel pipe is introduced, and an effective area of said fuel inlet of at least one of said holder means is different from the effective area of said fuel inlet of remaining holder means.
Claim 9
Dependent Claim
115 words
A fuel supplying device for an intenal combustion engine having multiple cylinder comprising: a plurality for fuel injection valves for injecting fuel toward said cylinder; a fuel pipe through which fuel flows; a plurality of holder means mounted on said fuel pipe so that the fuel from said fuel pipe is supplied to said holder means, said holder means accommodating said fuel injection valve so that the fuel is supplied to said fuel injection valve; and delaying means for delaying a start timing of the fuel supplied from said fuel pipe to at least one of said holder means from the start timing of the fuel supplied from said fuel pipe to remaining holder means.
Claim 10
Dependent Claim
115 words
A fuel supplying device for an intenal combustion engine having multiple cylinder comprising: a plurality for fuel injection valves for injecting fuel toward said cylinder; a fuel pipe through which fuel flows; a plurality of holder means mounted on said fuel pipe so that the fuel from said fuel pipe is supplied to said holder means, said holder means accommodating said fuel injection valve so that the fuel is supplied to said fuel injection valve; and delaying means for delaying a start timing of the fuel supplied from said fuel pipe to at least one of said holder means from the start timing of the fuel supplied from said fuel pipe to remaining holder means.
