The R11 marked a big step forward in fuel injection pump design and operation featuring 6 plungers (one for each injector), the complete removal of the separate corrector assembly, a start solenoid, and a 3D space cam for more accurate fuel mapping.

​

Six plungers allow for greater fuel efficiency, more control over each plunger and corresponding injector operation, and a greater ability to adjust the operation of the fuel injection pump for various environments, temperatures, and working conditions. Though advancements continued to be made, most fuel injection pumps would follow the R11 in general layout until continuous fuel injection (Bosch CIS) took over in the mid 70s.
