This means the Viper's exhaust goes into a silencer where the noise is damped by means of water spray.
He realized that if the building were sealed and the foul exhaust pumped into a 3, 600-degree cement furnace, the odor disappeared.
One is exhaust gas recirculation, which pumps cooled exhaust back into the engine air intake, lowering the combustion temperature and reducing NOx formation.
One hugely affective cue is auditory: Thanks to resonator tubes pumping intake and exhaust sounds into the cabin, the BRZ snarls and burrs and howls like a garage-built retro rod, even when it's accelerating away from a light like an ice-cream truck (0-60 mph in about 6 seconds).

In Europe the trucking industry has settled on a technology called selective catalytic reduction, in which urea is periodically injected into the exhaust system to break down the NOx, converting nitrogen oxides into (somewhat) harmless ammonia.
Rather than eliminate nitrogen oxide via a bulky chemical treatment system that even the EPA questioned initially, EGR would make the motor do all the work by piping exhaust gas back into the cylinders and burning it again a cleaner, cheaper, lower-maintenance solution, which would set Navistar ahead of the pack.

Houses with integral garages make it easier for exhaust fumes to leak into the home.
Injected into the exhaust stream, the solution's ammonia reacts in the de-NOx catalyzer to form nitrogen and water vapor.

In most systems that's done when a bit of diesel fuel is injected into the exhaust system, where it mixes with the stored NOx.
Over the past three years, thermoelectric materials have attracted intense interest from energy researchers trying to turn exhaust heat from automobiles into electricity that can be used by the vehicle.
Just after Discovery's engines fired, launch controllers noticed a small rectangular object drop from the bottom of the ship, carom off an engine bell and vanish into the exhaust flames.
The EPA pulled off the feat by sharply increasing the amount of oxygen-poor exhaust that is recirculated into the combustion chamber and increasing the pressure of the fuel being forced into the cylinder.
Thermoelectric materials convert low-grade heat wasted in industrial processes or exhaust systems of a vehicle into electricity.
Bolt comes with a trick-looking two-into-one exhaust system, which includes an oxygen sensor and exhaust gas catalyst that works with the closed-loop fuel injection system.
Typically, power plants release CO2 into the atmosphere through exhaust systems referred to as flues.
HCD-14 Genesis exhaust is ceramic-lined and was tuned for minimal backpressure, maximum high-rpm horsepower, and a deep baritone note, with cooling fins integrated into ultra-wide exhaust tips.

Will I have to dip into my savings a little or completely exhaust it in order to make the down payment?

The difference between turbocharging and supercharging is simple: a turbocharger boosts engine air pressure by using exhaust gas to power a turbine that pushes more air into the combustion chamber.

Apps such as as Instagram, Cinegram, and Vine that allow us to easily add aesthetic filters or animation or edited footage appeal because they turn us into artists rather than just people sharing the digital exhaust of our days.

"Rather than air being sucked into the radiators, the air is going straight over to the exhaust -- this benefits in terms of lower drag, " explains Scarborough.
These could be among the first full-scale power plants in the nation to turn powdered coal into a synthetic natural gas that is burned in a gas turbine whose exhaust gas powers a steam turbine.
With all of us starting to feel slightly ill from the heat, humidity, and exhaust fumes, we leave the crowded villages behind not a moment too soon and head into the lush green plantation country beneath Mount Kenya.
Imagine barreling through the Amazonian rainforest with machetes flailing from the windows of your off-road rig, and just as you're about to kick the vehicle into low gear, you pause to consider the impact of your vehicle's exhaust (among other things) on the delicate ecosystem around.

To supply the extra juice, utilities turn on inefficient single-cycle gas turbines, which turn 25% of the fuel's energy into electricity, as opposed to 45% for combined-cycle plants that use turbine exhaust to make steam to run a second generator.
