Abstract

A fuel injection system for internal combustion engines in which a high-pressure pump and a high-pressure reservoir is supplied with fuel at an injection pressure, from which reservoir the fuel arriving at injection is diverted as a function of time and quantity and delivered via a distributor to one of a plurality of injection points, via two sequentially electrically controlled valves. The injection points are triggered successively by a distributor opening of the distributor. With a fuel pressure, thus held at a certain pressure, in the high-pressure reservoir, a universally controllable fuel injection system is attained in a simple way, at little effort or expense.
