摘要： A fuel intake system for a combustion engine of a type having V-shaped first (1L) and second (1R) cylinder banks and also having a crank axis of the crankshaft, which comprises a throttle casing (3) disposed in a center space delimited between the first and second cylinder banks, elongated first (4L) and second (4R) 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 (5a) communicated with the throttle casing and first (5L) and second (5R) 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 (6c,6d;6i,6j) 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.

摘要： An intake system for an engine allows supercharging using the dynamic effect of intake air has a surge tank (4Q,4L) for a cylinder group in which cylinders are ignited in a sequence discontinuous with each other, a second surge tank (4b,4R) for another cylinder group in which cylinders are ignited in a sequence discontinuous with each other, a first upstream intake passage (5g,5L) for supplying intake air to the first surge tank, a second upstream intake passage (5g,5R) for supplying intake air to the second surge tank, a connecting tank (9) for communicating intermediate portions of the individual intake passages (6a- with each other, and a short connecting passage (31) for communicating upstream portions of the first upstream intake passage and the second upstream intake passage with the connecting tank (9). When the number of engine revolution is high, intake air is supplied to each of the cylinders through the connecting tank and the individual intake passage by taking advantage of the short connecting passage and bypassing a long upstream intake passage and the surge tank. Further, the short connecting passage does not adversely affect the effect to be produced by resonant supercharging because the upstream portion of the intake passage is communicated with the connecting tank. The intake system can shorten the length of passage for supplying intake air when the number of engine revolution is high due to inertia supercharging, without sacrificing the effect to be achieved by resonant supercharging.
