BMW B58
The BMW B58 is a Turbocharger, turbocharged straight-six engine, which began production in 2015. The B58 replaced the BMW N55, N55 and was launched in the BMW F30, F30 340i. The B58 is part of BMW's modular engine family, each engine using a displacement of per cylinder, following the BMW B38, B38 and BMW B48, B48 engine. The B58 engine was named to Ward's Ward's 10 Best Engines#Results, World's 10 Best Engines four times, in 2016 (installed in the BMW 3 Series (F30)#Petrol, 340i), 2017 (BMW 2 Series (F22)#Petrol engines, M240i), 2019 (BMW X5 (G05)#Petrol engines, X5) and 2020 (BMW 3 Series (G20)#Petrol engines, M340i). The S58 engine, which was released in early 2019, is the high-performance version of the B58. It was named to Ward's World's 10 Best Engines in 2023 (installed in the BMW M2#Second generation (G87; 2023–present), M2). Design Compared with its BMW N55 predecessor, the B58 features a 20% increase in boost pressure, a closed-deck engine block design, an increase ...

BMW N55
The BMW N55 is a turbocharged straight-six petrol (gasoline) engine that began production in 2009. The N55 replaced the BMW N54 engine and was introduced in the F07 5 Series Gran Turismo. The N55 was BMW's first straight-six engine to use a twin-scroll turbocharger. It also won three straight Ward's 10 Best Engines awards in 2011–2013. Following the introduction of the BMW B58 engine in 2015, the N55 began to be phased out. The BMW S55 engine is a high performance version of the N55 made by BMW M GmbH, which is used by the F80 M3, F82 M4 and F87 M2 Competition/CS. Design The main differences between the N55 and its N54 predecessor are the use of a single turbocharger, the addition of Valvetronic and the type of fuel injectors. Whilst the N54 used a twin-turbo arrangement, the newer N55 uses only a single twin scroll turbocharger. Valvetronic (variable valve lift) is claimed to improve throttle response, low-rev torque, exhaust emissions and to reduce fuel consumptio ...

BMW F30
The sixth generation of the BMW 3 Series consists of the BMW F30 (sedan version), BMW F31 (wagon version, marketed as 'Touring') and BMW F34 (fastback version, marketed as 'Gran Turismo') compact executive cars. The F30/F31/F34 generation was produced from October 2011 to 2019 and is often collectively referred to as the F30. For the sixth generation, the coupé and convertible models were spun off to create the new BMW 4 Series nameplate. BMW also introduced a separate hatchback model under the 3 Series nameplate called the 3 Series Gran Turismo (F34), similar to the BMW 5 Series Gran Turismo, 5 Series Gran Turismo. The F30 is the first generation of the 3 Series to be powered by a range of turbocharger, turbocharged engines exclusively and Power steering#Electric systems, electric power steering (replacing the hydraulic power steering systems used previously). The F30 also marked the 3 Series' first use of a three-cylinder engine in its 2015 facelift. A new plug-in hybrid F30 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Displacement (engine)
Engine displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. It is commonly used as an expression of an engine's size, and by extension as an indicator of the power (through mean effective pressure and rotational speed) an engine might be capable of producing and the amount of fuel it should be expected to consume. For this reason displacement is one of the measures often used in advertising, as well as regulating, motor vehicles. It is usually expressed using the metric units of cubic centimetres (cc or cm3, equivalent to millilitres) or litres (l or L), orparticularly in the United States cubic inches (CID, cu in, or in3). Definition The overall displacement for a typical reciprocating piston engine is calculated by multiplying together three values; the distance travelled by the piston (the stroke length), the circular area of the cylinder, and the number of cylinders in the whole engine. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compression Ratio
The compression ratio is the ratio between the maximum and minimum volume during the compression stage of the power cycle in a piston or Wankel engine. A fundamental specification for such engines, it can be measured in two different ways. The simpler way is the static compression ratio: in a reciprocating engine, this is the ratio of the volume of the cylinder when the piston is at the bottom of its stroke to that volume when the piston is at the top of its stroke. The dynamic compression ratio is a more advanced calculation which also takes into account gases entering and exiting the cylinder during the compression phase. Effect and typical ratios A high compression ratio is desirable because it allows an engine to extract more mechanical energy from a given mass of air–fuel mixture due to its higher thermal efficiency. This occurs because internal combustion engines are heat engines, and higher compression ratios permit the same combustion temperature to be reached wit ...

Engine Block
In an internal combustion engine, the engine block is the structure that contains the cylinders and other components. The engine block in an early automotive engine consisted of just the cylinder block, to which a separate crankcase was attached. Modern engine blocks typically have the crankcase integrated with the cylinder block as a single component. Engine blocks often also include elements such as coolant passages and oil galleries. The term "cylinder block" is often used interchangeably with "engine block". However, technically, the block of a modern engine (i.e., multiple cylinders integrated with another component) would be classified as a monobloc. __TOC__ Construction The main structure of an engine typically consists of the cylinders, coolant passages, oil galleries, crankcase, and cylinder head(s). The first production engines of the 1880s to 1920s usually used separate components for each element, which were bolted together during engine assembly. Modern en ...

BMW M2
The BMW M2 is a high-performance version of the BMW 2 Series automobile developed by BMW's motorsport division, BMW M GmbH. As the 2 Series replaced the 1 Series coupé and convertible models, the first-generation M2 was marketed as the most basic M model in the range. The first-generation M2 used the F8x chassis from the M3/M4, codenamed F87 and featured the BMW N55 series engine, while its successors, the M2 Competition and M2 CS, featured a twin-turbocharged engine developed by BMW M GmbH (S55 engine). The second-generation M2 uses the CLAR platform, codenamed G87, which it shares with the G80 M3 and G82 M4. It features the BMW S58 twin-turbocharged inline-six engine, developed by BMW M GmbH. __TOC__ First generation (F87; 2016) BMW M2 Coupé The M2 was unveiled in '' Need for Speed'' in November 2015, before later premiering at the North American International Auto Show in January 2016.

Ward's 10 Best Engines
Wards 10 Best Engines is an annual list of the ten "best" automobile engines available in the U.S. market, that are selected by '' Wards AutoWorld'' magazine. The list was started in 1994 for model year 1995, and has been drawn every year since then, published at the end of the preceding year. Engines must be available in regular-production vehicles on sale in the U.S. market no later than the first quarter of the year. Eligibility has also been based on availability in a vehicle below a base price limit, which increased progressively from for the 1995 list up to for the 2020 list; this limit was eliminated for future competitions following the announcement of the 2020 winners. During a 2-month testing period, Wards editors evaluate each engine according to a number of objective and subjective criteria in everyday driving situations – there is no instrumented testing. The selection takes into account power and torque output; noise, vibration, and harshness (NVH) levels; technic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
