In 4 stroke applications/cars, how far away from the head is the sensor installed and what are the reasons for that distance? Maybe there's a way to compensate for oil in the mixture and get correct readings. Would I run into the same issues that I would with lambada? Also I'm not sure how much the things I was told about lambada use in 2 stroke are true or not. I have not considered a gas analyzer so far. The egt sensor I was planned to use is a mainline EGT sensor with cold junction calibrated guage. The exhaust is made for top of rpm range in mind. It also alters how the power is delivered.įor the purpose of testing on the Dyno (limited time keep in mind) I am guessing that there will be a lot of steady throttle runs, but on the track it will be constantly changing. As for the second reason, the exhaust will work it's best at its target EGT, as temperature affects the speed of preassure waves, which is important in a 2 stroke (due to lack of exhaust valve) so that the preassures wave going back to the cylinder "blocks" the exhaust port so that unburnt mixture is not lost, improving the efficiency. The first reason is so that I know if the AFR is optimal (higher than target=lean, lower=rich) (but from what you're saying it seems that egt sensor will not do a great job at that). I'm responsible for the electronics/data logging side of things.Īchieving the correct EGT is in the real world is important to me, and I will know the target temp. I was told that Lambada sensor was a no go in a 2 stroke due oil intafearing with Lambada readings, as well as unburnt oil clogging the sensor up. It will also go out on track but that's not it's main pupose. This engine is mainly used as a development engine in a motorbike to see how much the design can be improved, how much extra horsepower can be gained on pump petrol and to then see how much power can be made on alternative fuels such as ethanol.
