Abstract
A diesel engine with an injection pump coordinated to each cylinder. The pump piston (13) of each injection pump is actuated by a cam (15) of a camshaft (12) by way of a roller tappet (14). Each roller tappet (14) is arranged in an individual tappet guide member (16) which is axially adjustably supported by means of two coaxial cylindrical guide pins (17, 18) in corresponding openings (19, 20) of the cylinder crankcase (11). By means of this arrangement, the position between cam (15) and roller tappet (14) and therewith the delivery start of the injection pump is adjustable by displacement of the tappet guide member (16). A universal applicability for diesel engines with different cylinder numbers is achieved by the individual arrangement of the tappet guide members (16), whereby additionally a simple manufacture and assembly is realized. The displacement of the tappet guide member (16) takes place by a control shaft (21) which is operatively connected with several coordinated tappet guide members (16) by means of eccentrics (22), whereby the rotary movement of the control shaft (21) is initiated by a lever (23) from a stroke-controlled power source.
