Four-stroke internal combustion engine with exhaust turbocharger

摘要

In addition to two inlet valves (2) the cylinders (1) of the four-stroke internal combustion engine with exhaust turbocharger (10) have a preliminary exhaust valve (3) for the expelled exhaust gases and a secondary exhaust valve (4) for the constant pressure exhaust gases. A separate exhaust pipe (6 and 8) each is provided for the expelled exhaust gases and the constant pressure exhaust gases, which are of constant cross-section over their length and each open into an inlet housing section (14; 15), into which the inlet housing (11) of the turbocharger turbine is divided by two partition walls (12). <IMAGE>
