ABSTRACT:
An air compressing reciprocating in-line compression-ignition internal combustion engine comprises for each cylinder a fuel injection unit comprising a fuel injection pump and a fuel injection nozzle. Each fuel injection unit is operated by a camshaft via a rocker lever and a cam follower roller mounted on said lever. The camshaft is rotatably mounted between the cylinders in transverse walls provided on the cylinder heads. The camshaft carries injection control cams and valve control cams for actuating the gas exchange valves by means of cam follower levers, which are pivoted at one end to the cylinder head and at the other end engage the gas exchange valves and are provided with cylindrically curved engaging surfaces for contacting the valve control cams. In order to provide an arrangement which involves only small material and space requirements and results in lower stresses on the injection control cams, the valve control cams and the cam follower levers, the center of curvature of the engaging surface associated with any one of said cylinders surface and a valve accelerating surface of the associated valve control cam are connected by a line which includes a smaller angle in excess of 30.degree. with the plane which is defined by the design center line of the camshaft and the axis of the cam follower roller for actuating the fuel injection unit that is associated with a cylinder that is adjacent to said given cylinder.
