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).
Water Injection and cooled exhaust gas recirculation (EGR) could be seen as competitive technologies: it has been demonstrated that at medium load a 40-50 % Water-to-Fuel Ratio (WFR) with Port Water Injection (PWI) has the same effect as an EGR-rate of 10%, which is seen as relatively limited even for petrol engines.

It is a family of 3-cylinder and 4-cylinder diesel engines featuring modular diesel engine system (MDB (Modularer Diesel Motor Baukasten)), [3] [4] [5] with dual-loop EGR system, with high pressure EGR and a cooled low-pressure EGR loops; variable valve train (VVT) with a camshaft adjuster, Bosch CRS 2-20 2000 bar common rail injection system ...
During model years 1982–1987, Audi issued a series of recalls of Audi 5000 (the North American name of the Audi 100 at the time) models associated with reported incidents of sudden unintended acceleration linked to six deaths and 700 accidents. [39] At the time, NHTSA was investigating 50 car models from 20 manufacturers for sudden surges of ...

Kidney problems. Kidney stones or infections can occasionally refer pain to the lower left abdomen, says Dr. Boxer. Similarly, urinary tract infections can also cause pain in this region, ...
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.
SunFed Produce has issued a voluntary recall for cucumbers distributed across 26 U.S. states and parts of Canada, the Food and Drug Administration said Friday. The action was taken due to concerns ...
