Volkswagen launched its newest concept car volkswagen XL1 and This is a review for volkswagen XL1 and compared with 1-Liter concept (L1), the new XL1 has a design even more impressive, plus the plug-in hybrid that combines the 48 HP two-cylinder TDI engine with 27 HP E-motor, dual-clutch transmission 7-speed (DSG), and lithium-ion battery. This concept can drive 35 miles in pure electric mode and provides fuel economy liter/100 0.9 kilometers. The car is powered by a compact 800 cc two-cylinder common rail TDI diesel engine developing 48 PS. This is connected with an electric motor produces 27 PS, so that a total of 75 PS - output a simple but more than enough if a low curb weight (795 kg) vehicle counts.
When the XL1 is the brake, E-motor operates as a generator that uses braking energy to charge the battery (battery regeneration). In certain operating conditions the load shared between the TDI engine and electric motor can be shifted so that the turbodiesel operate at efficiency levels of the most profitable. Gears of DSG 7-speed automatic move also was always selected in order to minimize energy usage. Machine controllers manage all the flow of energy and drive management tasks, taking into account the power required at any given moment by the driver. Some of the parameters used to achieve optimal propulsion mode for the given conditions are: gas pedal position and engine load, as well as energy supply and mix of kinetic and electrical energy at any given time.
Two-cylinder TDI using the technology of mass production: The 0.8 liter TDI (35 kW/48 PS) derived from 1.6-liter TDI, who drive cars like the Golf and Passat. The 0.8 TDI show the same data as the engine common rail 1.6-liter TDI in terms of distance of the cylinder (88 mm), cylindrical holes (79.5 mm) and stroke (80.5 mm). In addition, two-cylinder Volkswagen XL1 concept and mass produced four-cylinder engine shares key features internally to reduce emissions. They include special pistons niche for multiple injections and personal orientation of the jet injection of the individual. Here, both the smooth nature of common rail engine was moved to two-cylinder engine. in addition, the balancer shaft is driven by the crankshaft rotates at the same speed optimizes smooth running machine.
