The easiest way to explain the difference between gasoline and diesel engines is with “air” and “fuel.” In a gasoline engine, airflow is everything. You’re throttling air. A diesel mill is the polar opposite. It works on the premise of throttling the amount of fuel being injected—the air simply follows suit. Therefore there is no need to throttle the incoming air. To that end, there is also no vacuum created within a diesel engine.
