As long as you are willing to spray more oil (FOG) into the cylinder and don't care about the emission not reaching the standard, the effect is the same whether it is mechanical or electronic: refuel hard and the power is on call. Mechanical can't accurately control the concentration and quantity of oil mist, and supply is often greater than demand. The opening of several valves determines the concentration of oil mist mixed air and the quantity of oil mist entering the cylinder in unit time, which is basically equal to the estimated weight of vegetables sold by hand. The electronic precise control of oil mist concentration, quantity and spraying time is controlled by the timing of opening and closing of the injection nozzle after the high-pressure oil pump, which is equivalent to the weighing of the laboratory balance for vegetable selling.
