Abstract
The present invention provides a direct injection type multicylinder engine capable of reducing the dimensions and number of parts thereof by forming so as to be used in common the cam brackets for retaining cam shafts, clamp members for fixing adjacent injectors, and fixing stud bolts. The cam brackets comprise singly formed parts, and retain the cam shafts rotatably on a cylinder head. The clamp members are adapted to fix adjacent injectors to the cylinder head at once. The cam brackets and clamp members are fixed to the cylinder head by inserting first common stud bolts through the central portions of the cam brackets and those of the cam brackets. The engine can be miniaturized by reducing the distance between the cam shafts, and the number of the parts required to retain the injectors and cam shafts is reduced.
