The B48 engine was revised in 2018, dubbed "B48TU" ("Technical Update"), with notable changes and improvements; a new one-part timing chain as opposed to the earlier two-part, a new separate cooling circuits for the cylinder head and crankcase, and forged conrods and forged crankshaft is now 2.03 lb (1 kg) lighter due to the use of lighter ...
The BMW P48 Turbo is a prototype four-stroke 2.0-litre single-turbocharged inline-4 racing engine, developed and produced by BMW Motorsport for Deutsche Tourenwagen Masters. The P48 Turbo engine is full custom-built but partially borrows the cylinder blocks from BMW B48 road car engine which had a same displacement.
The Z4 range consists of the sDrive 20i which is only available in selected markets, the sDrive 30i and the range topping M40i models. The sDrive models are powered by the 2.0-litre B48 straight-4 engine while the M40i is powered by the B58 straight-6 engine. All engines come with forced induction and are mated to an 8-speed automatic transmission.
The BMW B58 is a turbocharged straight-six engine, which began production in 2015. [1] The B58 replaced the N55 and was launched in the F30 340i. [2]The B58 is part of BMW's modular engine family, each engine using a displacement of 500 cc (30.5 cu in) per cylinder, following the B38 and B48 engine.
The B47 engine is part of the modular family of engines, along with the B38, B48, B57 and B58. [1] The B47 complies with the Euro 6 emissions standard, and features a dual overhead camshaft with 4 valves per cylinder and a single turbocharger; while 165 kW (221 hp) and 170 kW (228 hp) engines feature twin-turbochargers.
Burnout in the box at Tarlton International Raceway, South Africa Fire burnout, Santa Pod Raceway, UK. The origins of burnouts can be traced to drag racing, where they have a practical purpose: drag racing slicks perform better at higher temperatures, and a burnout is the quickest way to raise tire temperature immediately prior to a race.
As per BMW example, current engine developments featuring water injection seem to concentrate on the effect of “Performance Improvement”. But by the mid 2020s, engine development will shift focus also on improved fuel consumption, due to the pressure on CO 2 emissions reduction and related regulations. [11] [12]
The North American P-51 Mustang makes significant use of the Meredith effect in its belly radiator design. [1]The Meredith effect is a phenomenon whereby the aerodynamic drag produced by a cooling radiator may be offset by careful design of the cooling duct such that useful thrust is produced by the expansion of the hot air in the duct.
