Diesel engines for land and marine work . e) are actuated by a single eccentric on the camshaft, this being possible since they are symmetricallyplaced, and in two-cylinder engines but one cam shaft andeccentric are usually employed, the valves of the secondcylinder remote from the cam shaft being operated by a con-necting lever between the two valves. For the workingof the fuel inlet valves a small subsidiary shaft is driven offthe cam shaft through gearing, at right angles to it, and aneccentric on this small shaft actuates the inlet valve the double acting machines, in order that

For the workingof the fuel inlet valves a small subsidiary shaft is driven offthe cam shaft through gearing, at right angles to it, and aneccentric on this small shaft actuates the inlet valve the double acting machines, in order that the piston rodmay not be subjected to the highest temperature, the fuelis injected on each side of the piston in pockets which areformed between the cylinder cover, the valve and the method is exceedingly helpful in avoiding trouble withthe stuffing boxes. The governor is mounted on a vertical governor shaftdriven off the crank shaft, and its action is the same as thatalready described for vertical engines in which regulation. [To face p:ige 102.
