air-fuel ratio
combustion air factor
air fuel ratio , AFR (Abkürzung)

Both actions are undesirable because they create inconsistencies in the air-fuel ratio.

They help determine, in real time, if the air-fuel ratio of a combustion engine is rich or lean.

Each mode is characterized by the air-fuel ratio.

The air-fuel ratio needed to stoichiometrically combust petrol, by contrast, is 14.64:1.

At rich air-fuel ratio, the exhaust gas temperature decreases due to the cooling effect of the fuel.

The straight-six biggest limitation through the years was poor distribution of air-fuel ratio to the cylinders.

In a typical chemical reaction, the air-fuel ratio must be a minimum of 14:1 (see Stoichiometry).

The air-fuel ratio is the most common reference term used for mixtures in internal combustion engines.

The range of air-fuel ratio between the rich and weak limits is reduced with an increase of air velocity.

Honda also tinkered with the engine's software, to regulate the air-fuel ratio for cleaner emissions.

Ultra lean mixtures with very high air-fuel ratios can only be achieved by direct injection engines.

Nearly all of these show the air-fuel ratio on a numeric display, since the wide-band sensors provide a much more accurate reading.

The test shows the inadequacy of the carburetor altitude control of air-fuel ratio for heights above 20,000 feet.

However, conversion efficiency falls very rapidly when the engine is operated outside of that band of air-fuel ratios.

High air-fuel ratios can also be used to reduce losses caused by other engine power management systems such as throttling losses.

This stratified-charge approach to lean-burn combustion means that the air-fuel ratio isn't equal throughout the cylinder.

This is necessary to run at extremely lean air-fuel ratios around 20 to 40:1 at certain engine load and revs.

The ECM does not measure the operating air-fuel ratio outside the stoichiometric range.

When catalytic converters were first introduced, most vehicles used carburetors that provided a relatively rich air-fuel ratio.

The speed with which the mixture burns depends also on the octane rating of the fuel and on the air-fuel ratio.

The programmable ECU enables user control of the air-fuel ratio.

By monitoring EGT, the driver or pilot can get an idea of the vehicle's air-fuel ratio.

At the stoichiometric air-fuel ratio, the generated O sensor voltage is about 450 mV.

The fuel injection volume was then accurately controlled by a computer using this detection signal to achieve lean air-fuel ratio feedback.
