Ischemia has long been hypothesized to prime the mechanisms leading to reperfusion injury and set the stage for an exaggerated, maladaptive vascular response resulting in tissue damage. Although ...

Modern internal combustion engines — including those that run on diesel fuel — require a lot of special parts and systems to prevent dumping excess emissions into the atmosphere. Not only are those ...

The secretion of glucocorticoids by the adrenal gland is important in mediating the behavioral consequences of stress 1,2,3,4,5. For example, the increase in glucocorticoid levels induced by acute ...

New patent suggests Porsche is looking at repurposing exhaust recirculation systems to clean catalytic converters more ...

EGR stands for exhaust gas recirculation, and the EGR valve is part of a system that does as the name implies: recirculate exhaust gas back into the engine’s intake manifold for a return trip to the ...

An EGR delete is seen by many as an easy way to improve performance and efficiency by removing the EGR (exhaust gas recirculation), which is a component that helps in reducing the NOx that is thrown ...

Controlling vehicle emissions in modern vehicles involves more than just bolting up a catalytic converter and calling it a day. There are other components that effectively, and intuitively, cut out ...

Knowing your vehicle can become beneficial in emergencies. If you are ever in a situation where you want to repair something quickly or change a component, there is nothing more cost-effective than a ...

LISLE, Ill. — It’s no secret that Navistar International had its share of EGR-related failures as it attempted to meet EPA10 emissions standards without the use of SCR exhaust aftertreatment. The ...

Your engine’s manifold absolute pressure (MAP) sensor is your little buddy. Buried somewhere in the stream of your charged intake air (usually in the manifold), it employs a little ceramic or silicone ...
