upper end and flared lower end of the injector tube
prevent water and compression leaks.
The exhaust passages from the exhaust valves of each
cylinder lead through a single port to the exhaust
manifold. The exhaust passages and the injector tubes
are surrounded by engine coolant.
In addition, cooling of the above areas is further ensured
by the use of water nozzles (Fig. 4) pressed into the
water inlet ports in the cylinder head. The nozzles direct
the comparatively cool engine coolant at high velocity
toward the sections of the cylinder head which are
subjected to the greatest heat.
The fuel inlet and outlet manifolds are cast as an
integral part of the current cylinder heads. Tapped
holes are provided for connection of the fuel lines at
various points along each manifold.
The water manifold is also cast as an integral part of the

provided at each cylinder. Water and oil passages
