Ein solches Bauteil neigt bei Herstellung aus Leichtmetall zu Spannungsrissen aufgrund thermischer Überlastung. Es wird daher erfindungsgemäß vorgeschlagen, dass im Abgaskrümmergehäuse (4) ein Kühlmittelkanal (30) ausgebildet ist, der fluidisch mit einem Kühlmittelkanal (32) im Turbinengehäuse (20) verbunden ist.
摘要:
Providing an exhaust gas energy recovery device by which the optimal engine operating condition can be continuously maintained in a manner that the flow rate of the engine exhaust gas fed to the power turbine is regulated so that the scavenging air pressure becomes optimal in order that the engine performance (the fuel consumption rate) corresponding to the engine load and the engine speed becomes optima. The engine exhaust gas energy recovery device provided the engine load detecting sensor, the engine speed detecting sensor and the scavenging air pressure detecting sensor, the device regulating the flow rate of the exhaust gas streaming into the exhaust gas turbocharger via controlling the flow rate of the exhaust gas streaming into the power turbine of the exhaust gas energy recovery device, so that the scavenging air pressure is maintained at an arbitrarily ordered level and the engine is operated under a condition that the fuel consumption rate is minimal.
