INSTATIONARY BEHAVIOR OF EXHAUST GAS TURBOCHARGED DIESEL ENGINES FOR PASSENGER CARS

BEITRAG ZYM INSTATIONAERVERHALTEN ABGASTURBOAUFGELADENER PKW-DIESELMOTOREN

Several test methods for the assessment of the instationary behaviour of internal combustion engines were compared on a modern high-dynamic motor test stand. Quantitative evaluation used load increase to a motor speed kept constant by the dynamometric brake and full load acceleration with constant angular acceleration by the usable speed range of the engine. The tests were carried out with a direct-injection diesel engine of a passenger vehicle with exhaust gas turbocharger. The test stand studies were supported by an easily applicable simulation program, which proved that during load increase the inertia moment of the exhaust gas turbocharger greatly influences the charging pressure while during engine acceleration it is the built-up of the turbine that mainly determines the speed of the charge pressure increase.
