Abstract

Separate valves 16 and 22 control fuel flow to respective sets of injection orifices 9 and 8 for full and partial load operation. The valves may be disposed side by side, Fig. 2 (not shown). A control valve operable in dependence on load may connect the inlet duct 35 or 45 to a supply pump or respective control valves (80, 81), Fig. 4 (not shown), may have pistons alternatively subject to a loading pressure. <IMAGE>
