I thought a conventional diesel injection system had a pump with a separate unit for each injector, and each injector just acts like a pressure relief valve when the injection pump pressurizes the line. So, I don't understand why the engine needs a lobe on the camshaft for each injector or what this cam lobe would do.
Can anyone explain or point me to a site that would explain?
