ABSTRACT:
A fuel intake system for a combustion engine of a type having V-shaped first and second cylinder banks and also having a crank axis of the crankshaft, which comprises a throttle casing disposed in a center space delimited between the first and second cylinder banks, elongated first and second surge tanks extending in a direction parallel to the crank axis and disposed on respective sides of the center space, and a passage system communicating the throttle casing to each of the first and second surge tanks. The passage system comprises a merging region communicated with the throttle casing and first and second branch ducts branched off from one end of the merging region opposite to the throttle casing. The first and second branch ducts connect to the first and second surge tanks, respectively. Each of the first and second branch ducts is comprised of two independent passages spaced apart from each other in a direction parallel to the crank axis. These two independent passages of each of the first and second branch ducts are communicated with different portions of the associated surge tank which are uniformly spaced from each other in a direction parallel to the crank axis.
