Replacing the 2.7-litre ‘biturbo’ V6 engine of the previous generation B5 S4, the new B6 S4 powertrain gained an all-aluminium alloy 4.2-litre, 40 valve (five valves per cylinder) V8 engine (parts code prefix: 079.C, identification code: BBK), with chain-driven double overhead camshafts, roller-finger rocker arm cam followers, and included variable inlet camshaft timing. It also used a strengthened alloy crankshaft bedplate for the five main bearings, and a two-part baffled oil sump, and a light-alloy variable intake manifold (VIM), containing the fractionally sequentially actuated fuel injectors. This petrol engine, based on the unit from the Audi A8, displaces 4,163 cubic centimetres (254.0 cu in), and it produces a motive power output of 253 kW (344 PS; 339 bhp) at 7,000 rpm, and generates torque of 410 N?m (302 lbf?ft) at 3,500 rpm, making it more potent than the RS2 Avant, and nearly as powerful as the B5 RS4. Engine management was by way of a Bosch Motronic ME 7.1.1 electronic engine control unit (ECU), using a Bosch ‘E-Gas’ drive by wire electronic throttle, and powering eight individual spark coils with longlife quad-electrode Bosch spark plugs. Ignition timing is a mapped direct ignition, with cylinder-selective knock control with the aid of four knock sensors. The exhaust system includes vacuum-operated valves in the twin rear silencers (mufflers), finished with chrome plated tail-pipes.
Like its predecessors, the B6 S4 was standard with a Getrag six-speed (M6S) manual transmission (parts code prefix: 0A3, identification codes: FVD, HEP) (gear ratios – 1st: 3.667, 2nd: 2.050, 3rd: 1.462, 4th: 1.133, 5th: 0.919, 6th: 0.778), with a 240 mm (9.4 in) single plate dry clutch, and Torsen T-2 quattro permanent four-wheel drive system. Final drive (parts code prefix: 01R, identification code: EXZ) ratios are 3.889, giving a top gear road speed to engine revs ratio of 24.4 miles per hour (39.3 km/h) per 1000 rpm. From July 2003, the ZF 6HP19 tiptronic automatic transmission (parts code prefix: 09L, identification codes: GUR, HHU) (ratios – 1st: 4.171, 2nd: 2.340, 3rd: 1.521, 4th: 1.143, 5th: 0.867, 6th: 0.691, with a final drive (identification code: GDF) ratio of 3.539) was included as an option.
An unusual sight in the engine compartment was the addition of water cooling for the 190 amp alternator, along with two additional thermostatically-controlled side-mounted radiators. mclaren wallpapers, lamborghini wallpaper, mazda wallpapers, Audi S4 wallpapers, mazda wallpapers
(Toyota Hilux)Hilux Sport Rider
Toyota introduced a mid-size SUV variant of the Hilux in 1998. The variant called the Sport Rider is a rare model, sold in a select few Asian markets, including Thailand and Nepal. Based on the Hilux, both in style and underpinnings, it is similar in concept to the Toyota 4Runner?however, the Sport Rider is not a rebadged 4Runner. The Sport Rider’s frame and suspension system are derived from the Hilux, including the Hilux’s independent front suspension and leaf-sprung rear. The model started out as the four-door pickup truck, but was modified into wagons on arrival in Thailand by Thai Auto Works Co (a majority Thai-owned company in which Toyota has a 20 percent stake). The vehicles were distributed by Toyota Tsusho Thailand, the importer of Toyota forklifts. Toyota Hilux wallpapers#Nissan370Z #volvo #Pagani #KoenigseggAgera #AudiRS3
