BMW N52
The BMW N52 is a Naturally aspirated engine, naturally aspirated Straight-six engine, straight-6 petrol engine which was produced from 2004 to 2015. The N52 replaced the BMW M54 and debuted on the BMW 3 Series (E90), E90 3 Series and BMW 6 Series (E63), E63 6 Series. The N52 was the first water-cooled engine to use magnesium/aluminium composite construction in the engine block. It was also listed as one of Ward's 10 Best Engines in 2006 and 2007. In European markets, the N52 began to be phased out in favor of its direct injected version, the BMW N53 in 2007. Markets such as the United States, Canada, Australia and Malaysia retained the N52 as the N53 was deemed unsuitable due to the high sulphur content of local fuel. The engine is equipped with a dual overhead cam 24 valve cylinder head and the crankshaft is held in place with 36 main bearing cap bolts. The static compression ratio is 12.5:1 advertised, requiring the use of 100 RON (94 AKI) fuel. The N52 and N53 are the l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Straight-six Engine
A straight-six engine (also referred to as an inline-six engine; abbreviated I6 or L6) is a piston engine with six cylinders arranged in a straight line along the crankshaft. A straight-six engine has perfect primary and secondary engine balance, resulting in fewer vibrations than other designs of six or fewer cylinders. Until the mid-20th century, the straight-six layout was the most common design for engines with six cylinders. However, V6 engines gradually became more common in the 1970s and by the 2000s, V6 engines had replaced straight-six engines in most light automotive applications. Characteristics In terms of packaging, straight-six engines are almost always narrower than a V6 engine or V8 engine, but longer than straight-four engines, V6s, and most V8s. Compared to V-configuration engines with similar power and displacement, the straight configuration has fewer injectors, a single head, and a single exhaust manifold, all contributing to better reliability and perfor ...

Electronic Throttle Control
Electronic throttle control (ETC) is an Automotive engineering, automotive technology that uses electronics to replace the traditional mechanical linkages between the driver's input such as a Car controls#Throttle control, foot pedal to the vehicle's throttle mechanism which regulates speed or acceleration. This concept is often called drive by wire, and sometimes called accelerate-by-wire or throttle-by-wire. Operation A typical ETC system consists of three major components: (i) an accelerator pedal module (ideally with two or more independent sensors), (ii) a throttle valve that can be opened and closed by an electric motor (sometimes referred to as an electric or electronic throttle body (ETB)), and (iii) a powertrain or engine control module (PCM or ECM). The ECM is a type of electronic control unit (ECU), which is an embedded system that employs software to determine the required throttle position by calculations from data measured by other sensors, including the accelerato ...

BMW E90
The fifth generation of the BMW 3 Series range of compact executive cars is designated under the model codes E90 (saloon), E91 (estate, marketed as 'Touring'), E92 (coupé) and E93 (convertible). The model was introduced in December 2004, and produced by BMW until October 2013 and is often collectively referred to as the E90, E9x, or occasionally, the E92. The E92 335i was the first 3 Series model produced with a turbocharged petrol engine. It was also the first 3 Series to include the iDrive operating system, which consists of navigation, infotainment and essential vehicle functions. The E9x saw the introduction of run-flat tyres to the 3 Series range. Models with run-flat tires are not equipped with a spare tyre. The E90/E92/E93 M3 is the only generation of M3 to be powered by a V8 engine. Introduced in 2007, it uses the BMW S65 naturally aspirated V8 engine and was produced in saloon, coupé and convertible body styles. Following the introduction of the F30/F31 3 Seri ...

Engine Control Unit
An engine control unit (ECU), also called an engine control module (ECM), is a device that controls various subsystems of an internal combustion engine. Systems commonly controlled by an ECU include the fuel injection and ignition systems. The earliest ECUs (used by aircraft engines in the late 1930s) were mechanical-hydraulic units; however, most 21st-century ECUs operate using digital electronics. Functions The main functions of the ECU are typically: * Fuel injection system * Ignition system * Idle speed control (typically either via an idle air control valve or the electronic throttle system) * Variable valve timing and/or variable valve lift systems The sensors used by the ECU include: * accelerator pedal position sensor * camshaft position sensor * coolant temperature sensor * crankshaft position sensor * knock sensors * inlet manifold pressure sensor ( MAP sensor) * intake air temperature * intake air mass flow rate sensor ( MAF sensor) * oxygen (lambda) s ...

Camshafts
A camshaft is a shaft that contains a row of pointed cams in order to convert rotational motion to reciprocating motion. Camshafts are used in piston engines (to operate the intake and exhaust valves), mechanically controlled ignition systems and early electric motor speed controllers. Camshafts in piston engines are usually made from steel or cast iron, and the shape of the cams greatly affects the engine's characteristics. History Trip hammers are one of the early uses of a form of cam to convert rotating motion, e.g. from a waterwheel, into the reciprocating motion of a hammer used in forging or to pound grain. Evidence for these exists back to the Han dynasty in China, and they were widespread by the medieval period. Camshafts were first described by Ismail al-Jazari in 1206. Once the rotative version of the steam engine was developed in the late 18th century, the operation of the valve gear was usually by an eccentric, which turned the rotation of the crankshaft into r ...
