don't know if you'll read this at this late date but, there is another aspect of diesels and the term direct injection. Engines that do not have direct injection have an injection pump mounted on the side of the block, gear driven by the cam or other accessory drive. There are steel tubes running from the pump to an injector nozzle, one for each cylinder. Looking like spark plug wires. Most Ag. engines are like this.

A direct injection engine has only a fuel supply pump visable on the exterior, the rest of the works is inside the rocker cover. The actual injector is situated in the cylinder head, it's nozzle end protruding into the cylinder. Each injector has a plunger that is operated by the cam shaft via a push rod and rocker arm. The injector are connected by a rack that contols the fuel delivery by varying the effective stroke of the plunger. The large Cummins and Detoits are examples of direct injection diesels. Look at a few, you won't see any sort of injedcton pump or lines on the outside of the engine.
