Übersetzung für "Rohemissionen" in Englisch

In this way, it supports the exact control of the fuel quantity and the optimisation of untreated emissions.

The untreated emissions of a diesel engine during the cold-start phase are composed substantially of unburned hydrocarbons.

The results including the untreated emissions of the vehicle are compiled in table 1.

Savings in consumption, lower raw emissions and a higher torque can be achieved as a result.

This reduces the dead space volume and considerably improves the raw emissions from the engine.

In addition, the new engine will assume market leadership in terms of untreated exhaust emissions.

First of all, in-engine measures minimise the untreated emissions.

Parallel to it, raw exhaust gas can be measured prior to the catalyst and afterwards.

The raw emissions of the engine and the space velocity within the converter are functions of the load and engine speed.

Reducing untreated emissions and improving exhaust aftertreatment constitute the biggest challenges in diesel technology today.

This is also conceivable for values of the exhaust gas mass flow and/or the raw emission of further exhaust gas components.

Reduced consumption, reduced untreated emissions and a higher torque can be achieved by using variable valve drives.

Benefits of a higher efficiency are a lower consumption, lower untreated emissions and therefore increased environmental compatibility.

As a consequence, a favourable effect on the combustion and untreated emissions can be assumed.

Emissions: A higher injection pressure is a key factor in reducing an engine's untreated emissions.

This design enables exhaust gas cooling levels of up to 40% and very low NOx engine-out emissions.

Optimisation of the engines and their combustion processes to reduce untreated emissions as far as possible.

The mode of operation with a nearly stoichiometric fuel-air relationship enables the already low raw emission of the engine to be further drastically reduced by means of a three-way catalytic converter subsequently added to it.

A change in the stroke of the intake camshaft, which is also provided, provides an additional opportunity for reducing raw emissions from the engine, since when the valve stroke is shorter, the intake means can be advanced even further for geometric reasons.

In particular, if the optimum value of the overlap range is exceeded, the combustion process deteriorates rapidly and thus produces a sudden rise in raw emissions.

First, the raw emissions from the engine of sulfur dioxide, hydrogen sulfide and carbonyl sulfide were determined using an ion-molecule reaction mass spectrometer (IMR-MS).

However, on the basis of the knowledge that reduction of the raw emissions produced directly by engine 1 is of critical importance for a further decrease in total pollutant emissions from engine 1, including the exhaust system that is not shown, operating point C2 is set instead.

Another disadvantage is that, as a result of the considerable richness required, crude emissions are significantly increased. Until ignition of the exhaust gas takes place, crude exhaust gas reaches the environment without any conversion.

The light-off temperature T CO,50%,fresh is a function of all the pollutant concentrations, that is to say the raw emissions of the engine, and the space velocity in the catalytic converter.
