English

Subject field(s)
  • Transformation of Momentum (Mechanical Components)
  • Engines (Motor Vehicles)
CONT

When a piston in an engine is pushed up into its cylinder, the upward movement traps the mixture of air and fuel above it and compresses it to one-eighth or one-ninth of its original volume. This puts the molecules closer together, so they hit the piston head far more often. Thus, the pressure goes up.

At its core the engine has a twin annular pre-mixing swirler(TAPS) combustor that pre-mixes the air and fuel before they are burned. This is designed to allow the combustion process to be more complete at lower temperatures.... The heart of the combustor is a pair of annular fuel/air "swirls" that pre-mix the two before funnelling the mixture to the relatively conventional combustor. The inner swirler is used for low-thrust requirements in idle and taxiing, while the outer swirler engages for higher thrust settings.

CONT

Constant Volume Sampler(CVS). Motor vehicle exhaust is a complex mixture of unburned fuel, combustion products(including a high water vapor content), and intake air that exits the tail pipe at high temperatures. In simulated driving conditions on the dynamometer, the volume of the exhaust emitted from the tail pipe is continually changing depending on where in the driving cycle the vehicle is(for example, during acceleration, during deceleration, at constant speed, or at idle). To quantitatively determine emission rates from vehicles, we use a constant volume sampling system, which maintains a constant total flow rate of vehicle exhaust plus dilution air. With a CVS system, as exhaust flow increases, such as during heavy acceleration, the dilution air is automatically decreased and the sampling source is representative of exhaust variations. This CVS system provides the source for all exhaust samples collected(regulated and unregulated). Because some compounds present in the exhaust are soluble in water, quantitative transfer requires that the diluted exhaust be maintained above its dew point by providing sufficient dilution air through the CVS. In addition, sampling components, such as the raw exhaust transfer duct and sample lines, must be heated to prevent water condensation.

CONT

An emission index (EI) specifies the number of grams of pollutant emitted per kilogram of fuel burned.

CONT

Research is aimed at a NOx Emission Index of 5, resulting in less than 1% annual ozone depletion.... From a technical standpoint, these critical emission levels depend on the engines’ injection and combustion system performance, i. e. the quality of the air/fuel mixture, its distribution in the combustor primary zone and the corresponding temperatures. The reduction of NOx emissions remains of primary concern, having the largest Emission Index(grams of emission produced per kilogram of fuel consumed) among the substances responsible for the ozone layer depletion.

CONT

The average emission rate of the smelters was 4.1 in 1998 [that is, the result of the following division: 9.9 million tonnes CO2 Eq divided by 2.4 m tonnes of shipments equals 4.1]. [In this case, the proper expression is "emission index" and not "rate", the term "index" being the numerical expression of a rate (or proportion).]

OBS

Le terme «indice» désigne une indication numérique qui sert à exprimer un rapport. Ne pas confondre avec «taux d'émission» ni avec «débit d'émission». Le terme «taux» désigne une proportion dans laquelle intervient un élément, un facteur variable, une quantité de quelque chose par rapport à une quantité d'autre chose (par exemple, on parle d'un taux d'émission de CO2 de x nombre de grammes par kilomètre pour une voiture). Le terme «débit» se rapporte à la quantité d'un polluant émis dans l'atmosphère par unité de temps. Enfin, voir aussi «facteur d'émission».

Subject field(s)
  • Aircraft Propulsion Systems
CONT

A supercharger which is located between the carburetor outlet and the intake manifold of the engine is called an internal supercharger. A supercharger thus located serves to provide a uniform distribution of the fuel-air charge to the various cylinders, as well as to increase the density of the charge. Maintaining a high manifold pressure ahead of the intake valves allows the use of "valve overlap" in the engine, so that the intake valve opens just before the exhaust valve closes at the end of the exhaust stroke. This allows the compressed mixture from the intake manifold to scavenge the spent gases out of the clearance volume of the cylinder and also tends to improve the cooling of the exhaust valve. This cooling is of particular importance when operating at "military" or "take-off" power. With no supercharging between the carburetor and the intake valves, "valve overlapping" would permit exhaust gases to flow back into the intake manifold. This would cause backfiring and dilution of the next charge of mixture with burned exhaust gases.

OBS

There is another difference between internally driven superchargers and turbochargers... The internal supercharger compresses the fuel/air mixture after it leaves the carburetor or fuel metering device, while the turbocharger compresses the air before it is mixed with metered fuel.
