Twin scroll turbocharger with waste heat recovery

Bypass air from downstream of the compressor is directed into a heat exchanger that draws heat from the exhaust gas of the engine. The bypass air does not include fuel, and instead is heated by the exhaust gas in the heat exchanger. The bypass duct enables air mass flow through the compressor to be increased, thereby preventing compressor surge at low engine speeds. The turbocharger turbine includes a dual entry scroll. The bypass air is fed into the first scroll after being heated in the heat exchanger, and the engine ' exhaust gas is fed into the second scroll. Use of two scrolls enables the blowdown impulse energy of the exhaust gas to be retained within the exhaust manifold prior to entry into the turbine, thereby providing improved turbocharger response and preventing backflow of exhaust gas into the bypass duct. Using the exhaust energy to heat the bypass air instead of combusting additional fuel leads to increased engine efficiency.

Motor vehicle with an underbody paneling

Eine Unterbodenverkleidung für den Heckbereich eines Kraftfahrzeugs deckt einen Endschalldämpfer ab. Zur Kühlung des Endschalldämpfers ist ein Lufteinlass in der Unterbodenverkleidung vorgesehen. Dieser Lufteinlass ist erfindungsgemäß in einem Bereich angeordnet, in dem sich bei Fahrt des Kraftfahrzeugs an der Unterseite der Unterbodenverkleidung ein höherer Druck einstellt als im Bereich des darüber angeordneten Bodenblechs. Somit kann kühlende Umgebungsluft mit geringen Strömungsverlusten in den Bereich des Endschalldämpfers geleitet werden. An underbody paneling for the rear of a motor vehicle covers an end muffler. To cool the rear silencer, an air inlet is provided in the underbody paneling. According to the invention, this air inlet is arranged in an area in which, when the motor vehicle is moving, a higher pressure is set on the underside of the underbody cladding than in the area of the floor panel arranged above it. Thus, cooling ambient air can be passed with low flow losses in the area of the muffler.
