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).
BMW recalled certain 2023-2024 X1, X5, X6, X7, XM, 530i, i5, 740i, 760i, i7, and 750e vehicles.. The NHTSA report said that the integrated brake system may malfunction and result in a loss of ...
A check engine light or malfunction indicator lamp (MIL), is a tell-tale that a computerized engine-management system used to indicate a malfunction or problem with the vehicle ranging from minor (such as a loose gas cap) to serious (worn spark plugs, engine problems or a faulty oil valve, etc.).
[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 ...

Myth #2: Red cars cost more to insure. One of the most persistent myths about auto insurance is that insurance companies charge more to insure red cars.
This differs from naturally aspirated applications where the intake manifold will remain in vacuum while under load. Thus, when a forced induction engine is under load, the intake manifold can no longer be used to draw blow-by gasses out of the crankcase and will instead begin to exacerbate the problem by increasing crankcase pressure.
