Abstract

In a distributor type fuel injection pump of the type including a plunger arranged for reciprocating and rotative motion, and a fuel injection quantity setting member slidably fitted on the plunger and engageable with a cut-off port formed in the plunger and communicating with a pump working chamber, a second cut-off port is formed in the plunger in communication with the pump working chamber, which opens in an outer peripheral portion of the plunger with which the fuel injection quantity setting member permanently slidably engages, and a plurality of spill ports formed in the setting member in a circumferentially spaced relation, which are smaller in number than the cylinders of an engine for use with the pump. When the plunger moves through each delivery stroke in a low engine load region, the second cut-off port engages each one of the spill ports successively to cause injection of fuel into only part of the engine cylinders.
