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 second radiator is plumbed in series with the main radiator in the circuit. This was the case when the Audi 100 was first turbocharged creating the 200. These are not to be confused with intercoolers. Some engines have an oil cooler, a separate small radiator to cool the engine oil.
Work Completed: Engine performance problem resolved by replacing one of the VarioRam lifters in the intake manifold, shock absorbers replaced with custom-made coilovers complete with Wheeler Dealers logos on top of the strut mounts, brake backing plates and suspension drop links replaced, faulty rear spoiler mechanism fixed by replacing broken ...
[77] [full citation needed] In turbocharged engines, EGR needs a controlled pressure differential across the exhaust manifold and intake manifold, which can be met by such engineering as use of a variable geometry turbocharger, [citation needed] which has inlet guide vanes on the turbine to build exhaust backpressure in the exhaust manifold ...
21% of Americans have chronic pain. A new study found that diets rich in vegetables, fruits, grains, lean proteins, and dairy was linked to less chronic pain.
