Abstract
A delivery pipe of a fuel supply system for injectors mounted on a cylinder head is divided for each injector or a group of injectors. Divided pipe parts are coupled with each other through a flexible member to allow flexing of the delivery pipe. Each injector is connected with the delivery pipe through a flexible coupling member and with the cylinder head through a flexible cushioning member. Alternatively, a fuel passage is formed in the cylinder head in place of the delivery pipe to supply fuel to the injectors after heating in the cylinder head.
