What is rotary injection pump?

What is rotary injection pump?

For use on cars and light trucks, the rotary pump or distributor pump was developed. It uses a single injection cylinder driven from an axial cam plate, which injects into the individual fuel lines via a rotary distribution valve.

What is the difference between rotary injection pump to inline injection pump?

An inline pump has multiple high-pressure pumps; one for each cylinder. This one has six pumps, one under each outlet port. A distributor pump has ONE high-pressure pump and uses a rotary valve to distribute high-pressure fuel to each cylinder.

How does a rotary fuel injection pump work?

Distributor (Rotary) Injection Pumps These types of pumps have only one fuel-metering plunger. A spinning rotor makes a hydraulic connection with the different ports on the distributor head, somewhat similar to the way a distributor works on a gasoline engine.

How do rotary pumps work?

Rotary vane vacuum pump works on a positive-displacement pumping principle. The design consists of a rotor, which is mounted eccentrically inside a cylindrical housing or stator. Blades, mounted inside the rotor, move in and out due to centrifugal force following the internal surface of the housing.

What are the benefits of a dp210 rotary fuel injection pump?

Delphi DP210 Rotary Mechanical Diesel Fuel Injection Pump Benefits • Light load advance enhancements are designed to help meet U.S Tier II and equivalent emissions standards. Retarded full load injection timing reduces nitrous oxide (NOx) emissions, and light load advance travel capability to 28° engine maintains misfire margin at part load.

What was the first rotary fuel injection pump?

The result was a revolutionary new design – the first single cylinder, opposed plunger, inlet metering rotary distributor-type diesel fuel injection pump. It was the smallest, simplest fuel injection pump the world had ever seen, at a much lower price than anything available before.

When was the rotary distribution pump first made?

From 1947 to 1952, activities were concentrated on laboratory developments and experimental installations. During 1952, production of the Model “A” pump was begun. This model remained in production through 1955. The rotary distribution pump played a key role in the rapid growth of diesel usage in farm tractors. 2

What kind of fuel injection pump does Delphi use?

POWERTRAIN SYSTEMS Delphi DP210 Rotary Mechanical Diesel Fuel Injection Pump The Delphi DP210 Rotary Mechanical Diesel Fuel Injection Pump is based on the Delphi DPA and DPS pumps, as well as the more advanced DP200 Series.
