<p>PROBLEM TO BE SOLVED: To reduce the number of parts and to improve assembling workability by forming a fuel rail 45 integrally with an intake manifold 21, preventing fuel from being heated. SOLUTION: The intake manifold 21 is formed by a downstream side manifold 22 and an upstream side manifold 23. In the downstream side manifold 22, a mounting seat 28 for fitting and holding one end part on a fuel injection port side of an injector 24 is formed. The upstream side manifold 23 is integrally provided with the fuel rail 45 and a holding hole 50 for fitting and holding the other end part on a fuel entrance side of the injector 24 is formed. Fuel is forcibly fed to the holding hole 50 from a fuel passage within the fuel rail 45.</p> |
