Earlier diesel engines were not refined      enough to win the hearts of many drivers but recent advances in technology made these engines      not only a worthy competitor in all areas but in some features—fuel economy or low end torque, to name just two—even exceeding the characteristics of their gasoline counterparts. And in addition to the general technological advantages,       Citroën’s diesel engines have a widely accepted       reputation—even among people blaming the quirkiness of its suspension or other features—of         being excellent and robust. As it is widely known, diesel engines have no ignition to initiate    their internal combustion, they rely on the self-combus- tionofthediesel oil entering into a cylinder filled with hot air. Due to this principle of operation, the supply of the fuel has to comply with much more demanding requirements than it is necessary in the case of gasoline engines. Unlike in the gasoline engine, not a mixture but air en- tersintothe cylinders via the inlet valves. During the adia- baticcompression all the energy absorbed is used to increase       the temperature of the gas. The small droplets of fuel will be injected at high velocity near the end of the com- pressionstroke into this heated gas still in motion. As they start to evaporate, they forma combustible mixture with the air present which self-ignites at around 800 °C. This self-ignition, however, is not instantaneous. The lon- gerthedelay between the start of the injection and the ac- tualignition (which depends on the chemical quality of the…
