Diesel exhaust is the exhaust gas produced by a diesel engine, plus any contained particulates. Its composition may vary with the fuel type, rate of consumption or speed of engine operation (e.g., idling or at speed or under load), and whether the engine is in an on-road vehicle, farm vehicle, locomotive, marine vessel, or stationary generator ...
Diesel particulate matter (DPM), sometimes also called diesel exhaust particles (DEP), is the particulate component of diesel exhaust, which includes diesel soot and aerosols such as ash particulates, metallic abrasion particles, sulfates, and silicates.
The oily exhaust pipe is therefore a "wet stack". This condition can have several causes. The most common cause is idling the engine for long intervals, which does not generate enough heat in the cylinder for a complete burn. "Idling" may be running at full rated operating speed, but with very little load applied. Another is excessive fueling.
"The more you idle, the more exhaust is released," she says. ... Experts say there are a few things to keep in mind when it comes to idling. If it's not overly hot or cold, the DOE says it's best ...
This is because it reduces the intake charge density. EGR is also omitted at idle (low-speed, zero load) because it would cause unstable combustion, resulting in rough idle. Since the EGR system recirculates a portion of exhaust gases, over time the valve can become clogged with carbon deposits, which will prevent it from operating properly.
The West will deal with rain on the first day of winter, the East and Great Lakes will get snow and cold, with very cold wind chills in the Northeast. Weird winter weather: Cold and snow to the ...
Diesel exhaust fluid (DEF; also known as AUS 32 and sometimes marketed as AdBlue [3]) is a liquid used to reduce the amount of air pollution created by a diesel engine. Specifically, DEF is an aqueous urea solution made with 32.5% urea and 67.5% deionized water .
Natural gas leaks happen nearly every day in the U.S. — and they can be deadly if they go undetected. A report from a group of Texas environmental nonprofits released in June found around 2,600 ...
