| 摘要 |
Pump component in a fuel injection pump in which fuel injection is controlled by at least one piston (3) which is movable in a cylinder (2) and which defines above the piston a chamber or space (12) in which fuel injection pressure is generated. The purpose of the pump component is to enable the fuel injection pressure to build-up relatively slowly in the chamber (12), preferably at relatively low engine speeds, so as to reduce the so-called ignition delay. The invention is mainly characterized in that the cylinder wall incorporates at least one through-passing bore (14) through which fuel is pressed during upward movement of the piston (3) in the cylinder (2). |
