The most attractive feature of the compression ignition (diesel) engine is its excellent fuel efficiency, which can surpass 40% in vehicular applications and even 50% in large, two-stroke units of marine propulsion or electrical generation. Consequently, vehicles equipped with diesel engines achieve much lower specific fuel consumption and reduced carbon dioxide emissions than their similarly rated spark ignition counterparts over the entire operating range, resulting also in considerable money savings over the vehicle’s lifetime. Moreover, diesel engines are characterized by low sensitivity in terms of air—fuel ratio variations, absence of throttling, high torque and high tolerability in peak cylinder pressures and temperatures that favors the application of various supercharging schemes.
