Audi announced the Q7 e-tron TFSI at the 2015 Shanghai Auto Show, developed specially for Asian markets (China, South Korea, Singapore and Japan). Its 2.0 TFSI and electric motor deliver 270 kW (362 hp) and 700 N⋅m (516 lb⋅ft) of system torque – enough to accelerate from 0 to 100 km/h (62 mph) in 5.9 seconds and for a top speed of 220 km ...
Copper at red heat (300-400°C) combines directly with chlorine gas, giving (molten) copper(II) chloride. The reaction is very exothermic. [8] [15] Cu(s) + Cl 2 (g) → CuCl 2 (l) A solution of copper(II) chloride is commercially produced by adding chlorine gas to a circulating mixture of hydrochloric acid and copper. From this solution, the ...
The same hydrochloric acid solutions also react with acetylene gas to form [CuCl(C 2 H 2)]. Ammoniacal solutions of CuCl react with acetylenes to form the explosive copper(I) acetylide , Cu 2 C 2 . Alkene complexes of CuCl can be prepared by reduction of CuCl 2 by sulfur dioxide in the presence of the alkene in alcohol solution.
The following list of Audi vehicles, including past and present production models, as well as concept vehicles and limited editions.The current era of Audi production dates to 1968, when present-day owner Volkswagen Group, which had purchased Auto Union from Mercedes-Benz in 1965, debuted the first modern Audi-branded vehicles.
There are four means used by the agents to extinguish a fire. They act on the "fire tetrahedron": [1] Reduction or isolation of fuel. No agents currently use this as the primary means of fire suppression. Reduction of heat. Representative agents: Clean agent FS 49 C2 (NAF S 227, MH227, FM-200), Novec 1230, pentafluoroethane (NAF S125, ECARO-25).
two single-entry air filters each with hot-film air mass flow meters (Q7), or triple-entry single air filter with single hot-film air mass meter (RS 4), or double-entry dual-element single air filter with two hot-film air mass flow meters (R8); single (Q7 & RS 4) or twin (R8) cast alloy throttle body electronically controlled Bosch E-Gas ...
The SQ8 features a larger 4.0-litre V8 petrol engine with an output of 500 hp (370 kW) and 568 lb⋅ft (770 N⋅m), giving it a 0 to 60 output in 4.1 seconds and an electronically limited 155 mph (249 km/h). The unit can switch off four of its cylinders almost instantly to reduce fuel consumption when extra power is unnecessary.
Thus MQB coordinates a core "matrix" of components across a wide variety of platforms — for example, sharing a common engine-mounting core for all drivetrains (e.g., gasoline, diesel, natural gas, hybrid and purely electric), as well as reducing weight. The concept allows different models to be manufactured at the same plant, further saving cost.
