Sentences with phrase «lean mixture»

If you have a faulty oxygen sensor, the worst that could happen is that you have either too rich or too lean mixture.

The resultant leaner mixture reduces emissions, increases fuel efficiency and increases power.

The resultant leaner mixture reduces emissions, increases fuel efficiency and helps increase power.

Compression ignition — as used in diesel vehicles — has been tried in petrol cars before at the prototype stage, but controlling the point at which the fuel - efficient lean mixture burns spontaneously under heat and compression has proved difficult.

If the timing is wrong you might get a misfire but that is not dependent on lean mixture?

If it is smooth, it adjusts the carburettor settings to add more air, creating an increasingly lean mixture until it detects roughness.

Notice that the after cat sensor (green line) is low on the graph indicating an overall lean mixture and that the voltage amplitude is relativly small.

The probe then tends to report lean mixture, the ECU enriches the mixture, the exhaust gets rich with carbon monoxide and hydrocarbons, and the fuel economy worsens

This is counterintuitive: Lean mixtures at high exhaust flow rates can damage a catalyst.

The PCM is trying to ignite a very lean mixture; the best time to do that is after the heating of compression is done but before the pressure drops too much.

Could that cause lean mixture codes?

Lean mixtures burn slower and therefore must be ignited earlier to keep that cylinder at the maximum brake torque timing point.

I used a leaner mixture of minced beef and pork to make the filling for the Easy Stuffed Savoy Cabbage with Minced Meat.

Ward's solution was to help the lean mixture to start off burning by pumping in more energy through a different kind of spark plug.

After months of troubleshooting he finally tore the heads off and discovered burned valves and gave attribution to the short pipes rather than his lean mixture and retarded timing.

The lean mixture contains more oxygen and that excess oxygen is used to oxidize the CO into CO2 and break the HC into CO2 and H2O.

As the piston reaches top dead centre the plug ignites this richer mixture, the expansion of which raises pressure in the combustion chamber — enough to simultaneously ignite the lean mixture around it with compression alone.

That usually means a lean mixture, which could be caused by a whole bunch of things»

How this works it that the lean mixture does not burn in the cylinder but does in the catalyst if it is hot enough.

Some systems will command a lean mixture to save a bit of fuel.

Assuming the readings obtained are accurate the CO is not an indication of a lean mixture.

@DizzyFool Exhaust leaks would lean the mixture (lambda) at the tailpipe as measured by the gas analyzer portion of the MOT test.

From the spark plugs you can tell how rich or lean the mixture is, or if the motor burns oil.

How does a lean mixture not completely burn in the cylinder?

The Colortune isn't to determine the color of the spark, but for the color of the combustion itself, which is useful for tuning fuel / timing (leaner mixtures will be bluer in color, where richer mixtures are redder.

A higher percentage of fuel to air is described as a rich mixture, while a lower percentage of fuel to air is termed a lean mixture

Especially when hot, when the engine gets a leaner mixture of air and fuel, the idle air control will have a greater effect on idle...

Also, leaner mixtures can also be tolerated for better fuel economy.

Because our fuel isn't clean enough (meaning too much sulfur), we can't run a lean mixture, and so the FSI isn't working to full potential.

With the aid of simulations for the fuel mixture and the combustion process, the pistons have been designed with special piston bowl geometry which concentrates the lean mixture in the area around the spark plug and prevents it from spreading out towards the cylinder wall.

In the BMW application, the engine is able to run on a lean mixture all the way from idle speed to high revs.

Japanese buyers were liable for more annual road tax for selecting the 2.6 l engine over the smaller engines The US version also featured a «Jet Valve», a small secondary intake valve which improved emissions by enhancing swirl in the combustion chamber, allowing for burning of a leaner mixture.
