The goal of EGR is thus to reduce NO x production by reducing the combustion temperatures. In modern diesel engines, the EGR gas is usually cooled with a heat exchanger to allow the introduction of a greater mass of recirculated gas. However, uncooled EGR designs do exist; these are often referred to as hot-gas recirculation (HGR).
The BMW N52 is a naturally aspirated straight-6 petrol engine which was produced from 2004 to 2015. The N52 replaced the BMW M54 and debuted on the E90 3 Series and E63 6 Series . The N52 was the first water-cooled engine to use magnesium/aluminium composite construction in the engine block. [ 1 ]
BMW is well known for its history of inline-six (straight-six) engines, a layout it continues to use to this day despite most other manufacturers switching to a V6 layout. . The more common inline-four and V8 layouts are also produced by BMW, and at times the company has produced inline-three, V10 and V12 engines, BMW also engineered non-production customised engines especially for motorsports ...
A straight-twin engine, also known as an inline-twin, vertical-twin, inline-2, or parallel-twin, is a two-cylinder piston engine whose cylinders are arranged in a line along a common crankshaft. Straight-twin engines are primarily used in motorcycles; other uses include automobiles, marine vessels, snowmobiles, jet skis , all-terrain vehicles ...
bmw b37 (d16, 1.6l), bmw b47 (d20, 2.0l) BMW N47 is a four-cylinder common rail diesel engine that has many improvements over its predecessor, the M47 . In 2014 it was replaced with the B47 .
1952 Shell Oil film showing the development of the diesel engine from 1877. The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is called a compression-ignition engine (CI engine).
It is somewhat similar to RS-232; however, the signal levels are different, and communications happen on a single, bidirectional line without additional handshake signals. ISO 9141-2 is primarily used in Chrysler, European, and Asian vehicles. pin 7: K-line; pin 15: L-line (optional) UART signaling; K-line idles high, with a 510 ohm resistor to ...
The BMW M67 is an automobile diesel engine, used in the BMW 7 Series. It was first introduced in 1998, and used until 2009. The engine is a common rail turbodiesel V8 design, using double overhead camshafts and 32 valves. It is the first luxury car application of a bi-turbo diesel intercooled V8 engine.
