On the other hand, it is well known that in an internal combustion engine up to 35% of the energy developed by the fuel combustion is dissipated in the exhaust gases. The OSU EcoCAR prototype vehicle features an extended-range electric architecture with a downsized 1.8L Exhaustgas exergy map of EcoCAR engine.
In the previous model, some of the gasoline engines were mounted with a forward tilt of 10 degrees, and their exhaust side faced the radiator grille, while the exhaust side of the TDI engine faced the bulkhead. The turbocharger was redesigned for the use of low-pressure exhaustgas recirculation. Click to enlarge.
An actuator in the exhaust system, as fitted to the first SQ5 TDI, gives the V6 a sonorous sound. This offers the advantage since exhaustgas cleaning responds more quickly. The exhaust manifold benefits from improved insulation; the exhaustgas reaches the optimum temperature more quickly after a cold start.
The BMW M550d xDrive Sedan, the most fuel-efficient of the new series, accelerates from 0 – 100 km/h (62 mph) in 4.7 seconds and has a top speed of 250 km/h (155 mph). The vehicle meets Euro 6 exhaust standards. Average fuel consumption is 6.3 liters/100 kilometers (37.3 mpg US), with CO 2 emissions of 165 g/km.
Exhaust cooling starts with the computer-optimized exhaust valve shape and is further enhanced by the integrated exhaust manifold and cylinder head design that uses the same water jacket to lower exhaustgas temperature entering the turbochargers to further improve reliability and performance.

An exhaustgas recirculation system, oxidation catalytic converter and diesel particulate filter are used to reduce emissions values. The electric motor is supplied with energy from the 8.6 In all-electric operation the twin up!
whenever the driver releases the accelerator pedal or brakes—the system elevates the voltage of the alternator (generator), and this electricity is used to intensively charge the vehicle’s battery. The constantly fully charged battery supplies the vehicle’s electrical system during the stopped phase of the engine (e.g.
seconds to accelerate from 80 to 120 km/h (50 to 75 mph) for overtaking. Newly developed piezo injectors take advantage of the fact that piezoceramics change their crystal structure—and therefore their thickness—in a matter of nanoseconds when electrical voltage is applied. Fuel consumption is 6.7
With a total system output of 134 hp (100 kW), the CT 200h will accelerate from 0-60 mph in 9.8 The electric motor, generator and power split device are all housed in one lightweight, highly compact transmission casing directly comparable in size to that of a conventional gearbox. km) at speeds of up to 28 mph (45 km/h).
Earlier, at the SAE 2009 World Congress, FEV had displayed a 295 cc Wankel genset for extended range electric vehicles. The vehicle can accelerate to 60 km/h (37 mph) in less than 6 seconds, and top speed is higher than 120 km/h (75 mph). Tags: Electric (Battery) Hybrids Plug-ins. Earlier post.). Powertrain elements.
To further optimize gas exchange, the valve control system has been given greater operating freedom. The Audi valvelift system, which adjusts the lift of the valves in two stages, is active on the exhaust side. This concept benefited from the integration of the exhaust manifold into the water-cooled cylinder head.
In addition there are two gas engines, adaptable to run on biogas, compressed natural gas (CNG) or liquefied LNG. The exhaust brake output is 320 kW at 2,400 r/min. The exhaust brake is rated at 256 kW at 2,400 r/min. A fixed-geometry turbocharger and an electric intake throttle are used.

By way of comparison: a conventional turbo system diverts part of the exhaustgas stream needed for the forced induction away from the turbine via a wastegate valve as a function of its operating state. TSI ACT BlueMotion, however, it is possible to route 100% of the exhaustgas stream via the turbine at any time by means of VTG.
