For manual transmission equipped cars, it is a component that replaces the stock gear selector (shifter). A shift kit usually shortens the throws of selecting a gear (also known as a short throw shift or short shifter), therefore allowing a driver to reduce the shift time and change gears more efficiently.
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 M67 is an automobile diesel engine, used in the BMW 7 Series. It was first introduced in 1998, and used until 2009. 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.
The BMW M43 is an SOHC four-cylinder petrol engine which was produced from 1991-2002. [1] The M43 powered base-model cars, while higher performance models at the time were powered by the BMW M42 and BMW M44 DOHC engines. The M43 was produced at the Steyr engine plant. [2] A version using natural-gas was produced for the E36 318i and the E34 518i
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 shift kit is also intended to reduce the shift time of a manual vehicle. With a manual transmission, upshift time can be reduced by installing a lighter flywheel. During an upshift, the engine speed must decrease to synchronize with a higher gear; a lighter flywheel will allow the engine speed to drop more quickly, leading to shorter shift times.
A direct-shift gearbox (DSG, German: Direktschaltgetriebe [1]) [2] [3] is an electronically controlled, dual-clutch, [2] multiple-shaft, automatic gearbox, in either a transaxle or traditional transmission layout (depending on engine/drive configuration), with automated clutch operation, and with fully-automatic [2] or semi-manual gear selection.
The BMW M42 is a DOHC straight-four petrol engine which was produced from 1989-1996. [1] It is BMW's first mass-production DOHC engine and was produced alongside the BMW M40 SOHC four-cylinder engine as the higher performance engine. The M42 was replaced by the BMW M44, which was introduced in 1996.
