The high-pressure injection systems in modern diesel engines place high requirements on fuel quality.Due to the increase in injection pressure (to at least 2000 bar) and to growing biodiesel fractions in fuel,efficient particle and water separation is becoming ever more important for protecting the engine from abrasion. MANN+HUMMEL fuel filters ensure that impurities and any water contained in the fuel do not damage the engine.Whether prefilter or main filter, MANN + HUMMEL offers a comprehensive fuel filtration range for virtually any application – for spark-ignition as well as diesel engines.
