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).
An early prototype iDrive (called the Intuitive Interaction Concept) was featured on the BMW Z9 concept in 1999. The production version debuted in September 2001 in the BMW 7 Series (E65) and was built on the VxWorks kernel [4] while the Navigation computer used Microsoft Windows CE for Automotive; [5] this can be seen when the system reboots or restarts after a software crash, displaying a ...
For instance, on the Corvette there are interfaces for the Class 2 serial data stream from the PCM, the CCM diagnostic terminal, the radio data stream, the airbag system, the selective ride control system, the low tire pressure warning system, and the passive keyless entry system. [21] An OBD 1.5 has also been used in the Ford Scorpio since 95 ...
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).
[4] [5] In the U.S. state of Ohio, state law allows a board of county commissioners or township trustees to prohibit the use of compression brakes within unincorporated areas. These local regulations apply to all state- and locally-maintained roads except Interstate highways. The state's standard "No Engine Brake" sign is designed to avoid ...
[2] On slow-moving delivery vehicles and boats, there was often no suitable air slipstream for the road draught tube. In these situations, the engines used positive pressure at the breather tube to push blow-by gases from the crankcase. Therefore, the breather air intake was often located in the airflow behind the engine's cooling fan. [1]
The 5 Series is BMW's second-best-selling model after the 3 Series. [2] On 29 January 2008, the 5 millionth 5 Series was manufactured, a 530d sedan in Carbon Black Metallic. [3] It is BMW’s oldest nameplate still in production and the first model line to use "Series" in the name, debuting the three-digit model naming convention still used ...
The introduction of the eStar was supported by a US$39.2 million U.S. Department of Energy stimulus grant under the 2009 American Recovery and Reinvestment Act. [62] The eStar had a 5,100 lb (2,300 kg) payload capacity available with a 14- or 16-foot cargo box.
