Title: Direct fuel injection engine
Inventor: KATAYAMA GOICHI
IPC: F02F1/24
Filed: 2008-04-23
Abstract: <P>PROBLEM TO BE SOLVED: To provide a direct fuel injection engine provided with a pent-roof type piston capable of reducing heat damage on a fuel injector while securing an opening area of a valve hole.  <P>SOLUTION: A width A of a top part 16a of a lower surface of a cylinder head 16 facing to a pent-roof type top surface of the piston 13 is formed to be smaller than a diameter B of an injector mounting hole 16b opened there. Thus, even when a diameter of a suction valve hole 17 of the cylinder head 16 is increased as much as possible, the suction valve hole 17 becomes unlikely to interfere with the top part 16a. Thus, deformation of the suction valve hole 17 can be suppressed minimally and suction efficiency can be improved. When the width A of the top part 16a of the cylinder head 16 is reduced, an exposure amount of a tip end part 23a of the fuel injector 23 increases and the injector becomes susceptible to the heat damage. However, an annular heat shielding boss part 16c is projected to the lower surface of the cylinder head 16 so as to surround an opening edge of the injector mounting hole 16b to protect the tip end part 23a of the fuel injector 23 from the heat damage.  <P>COPYRIGHT: (C)2010,JPO&INPIT
