Summary:

Forced-induction spark-ignition engines for passenger cars haveundergone rapid development in just a few years. The developmentsteps towards reducing consumption, improving response andincreasing durability have required considerably less time than inthe case of the naturally aspirated engine. Forced-inductionengines currently employ exhaust gas turbo-charging almostexclusively. By this means the required quantities of air can besupplied with acceptable size, weight and efficiency, together withthe advantage of good acoustic characteristics. In step with thecombustion engine, the turbo-charger is also undergoing continuousfurther development.The paper describes the individual development steps, which canbe divided into four stages. Particularly good results can beobtained with forced-induction engines incorporating four valvesper cylinder.Compared with naturally aspirated engines, forced-inductionspark-ignition engines place significantly greater demands on theengine ancillary systems. The higher output levels necessitate theuse of inter-cooling, sophisticated ignition and injection systems,heat resistant materials and more efficient cooling, all of whichmake turbo-charged engines more expensive. The most suitableapplications are thus primarily in the performance car category, orfor fast touring saloons
