Abstract
An engine system includes a compression ignition engine having an exhaust gas recirculation system incorporating a spindle mounting a valve. A fuel pump having a fuel lever supplies fuel to the engine and the spindle is connected to a control means which reduces the amount of exhaust gas recirculated as the fuel supply to the engine is increased. The control means is slow acting and in order to reduce the amount of exhaust gas recirculated in the event of a rapid movement of the control lever in a direction to increase the fuel, a linkage is provided connecting the control lever to the spindle. The linkage incorporates a piston cylinder combination which transmits rapid movement of the control lever to the spindle only when the control lever is moved to effect an increase in fuel.
