<P>PROBLEM TO BE SOLVED: To provide a piping structure of fuel injection pipes for an engine having advantages of improving engine performance by reducing dispersion of the fuel injection quantity, and improving productivity and reliability of the piping structure. <P>SOLUTION: Cylinder heads 100a-100f are provided with fuel injection valves 101a-101f respectively. The respective fuel injection valves 101a-101f are connected to joints 105a-105f in a common rail extending in aline through the fuel injection pipes 103a-103f. In this case, the fuel injection pipes 103b, 103c, 103d, 103e are crossed and connected to equalize the length of all the fuel injection pipes 103a-103f. Dispersion of the fuel injection quantity can thereby be reduced to improve engine performance. <P>COPYRIGHT: (C)2008,JPO&INPIT |
