In diesel engines in particular, EGR systems come with serious drawbacks, one of which is a reduction in engine longevity. For example, because the EGR system routes exhaust gas directly back into the cylinder intake without any form of filtration, this exhaust gas contains carbon particulates. And, because these tiny particles are abrasive ...
Fuel system: Common rail direct injection: Fuel type: Diesel fuel DIN EN 590: Oil system: Wet sump, pressurized circulation: Cooling system: Water-cooled: Output; Power output: 195–294 kW (261–394 hp) Torque output: 620–760 N⋅m (457–561 lb⋅ft) Chronology; Predecessor: BMW N57
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.

In addition to changing the fuel, US engineers have also come up with two other principles and distinct systems to all on-market products that meet the U.S. 2010 emissions criteria, [citation needed] [needs update] selective non-catalytic reduction (SNCR), and exhaust gas recirculation (EGR). Both are in the exhaust system of diesel engines ...
Air-to-liquid intercoolers are usually heavier than their air-to-air counterparts, due to additional components making up the system (e.g. water circulation pump, radiator, fluid, and plumbing). The majority of marine engines use air-to-liquid intercoolers, since the water of the lake, river or sea can easily be accessed for cooling purposes.
A growing body of evidence has shown links between cancer and drinking alcohol. In a warning Friday, U.S. Surgeon General Vivek Murthy said cancer risk increases with the number of drinks, but ...
SPOILER ALERT: This article contains major plot details from the finale of Edward Berger’s “Conclave.” Megyn Kelly took to X to criticize Edward Berger’s “Conclave” as a “disgusting ...
A crankcase ventilation system (CVS) removes unwanted gases from the crankcase of an internal combustion engine. The system usually consists of a tube, a one-way valve and a vacuum source (such as the inlet manifold). The unwanted gases, called "blow-by", are gases from the combustion chamber which have leaked past the piston rings. Early ...
