Mixing meter (AFR GAUGE)

Mixing meter for fixed mounting in the car or for temporary mounting, eg for running in or testing cars. We have several different mixer / wideband lambda probes, from eg AEM, PLX, Innovate, and Vems. When installing a mixer, the lambda probe must often be calibrated, this you must remember to do when the probe is not mounted in the exhaust, or it must have stood for 3-4 days without starting.

If you have a request for another watch, feel free to contact us.

Measurement of the mixture

Adjusting an engine's petrol/air mixture is something that can be done easily with one of the products below. It is a must for a correct adjustment that you have an opportunity to be able to read the combustion. The mixing ratio of a petrol engine must be 14.7 kg of air to 1 kg of petrol (14.7: 1). However, this is not the most effective mixture. If you go for power from the engine, approx. 10% more gasoline. If the best economy is sought, approx. 10% less petrol, a lean mixture, however, gives more heat development and less power.

The optimal setting to look for when looking at the entire rev range is a slightly fatter mixture at idle, slightly leaner at half throttle, and a slightly fatter at full throttle.

Another way to express the mixing ratio is via, the air excess number. The excess air number is an expression of the mixing ratio and a number of 1.0 (lambda = 1.0) corresponds to a ratio of 14.7: 1. For a petrol engine, the number must be between 0.6 - 1.2, these are the absolute outer limits.
