MAP MAF LAMBDA (air:fuel ratio) - Volvo V70 D3 2011 - Car Scanner PRO app

Normal driving in Volvo V70 D3 2011 Geartronic. Recorded values MAF, MAP, o2:s1 air:fuel ratio (lambda), air mass, etc. 00:00 Intro 00:07 Lambda at engine start 00:17 Air:fuel at DPF regen 00:28 Air mass 00:38 change units 01:22 Air mass desired/actual 01:51 MAP MAF 02:20 kg/h psi 02:20 g/s kPa Volvo D5205T3 1984 ccm 5-cylinder D3 engine, Geartronic 6-speed transmission Car Scanner Pro ELM OBD2 app iCar 2 Vgate bluetooth adapter Attention: if 02:S1 air fuel (lambda) values in your Diesel show very high values (28-29), you need to change fuel type from Gasoline to Diesel in Settings/Fuel consumption Lambda ( λ ) λ (lambda), is the ratio of actual air:fuel ratio (AFR) to stoichiometry for a given mixture. λ = 1.0 is at stoichiometry, in rich mixtures λ is less then 1.0, and lean mixtures λ is more than 1.0. For diesels the the limit is around λ = 1.25 (rich) and there is no limit for lean (as little needed to run the engine). When engine is idling λ = 2 on my video. Under DPF regeneration (when engine is idling) the lambda λ = 1.5 - 1.7 Lambda ("02S1 fuel:air") parameter can be used to control if DPF regen is ongoing - if lambda is less than 2 (when car is fully stopped and engine is idling), the DPF regen is ON. Lambda values in Volvo V70 D3: DPF regen and lambda in Volvo D3: The O2S1 sensor shows 0 for approx. 1-2 minutes, while sensor is heating up. The heated oxygen sensor is a broadbanded zirconium sensor and works with current control. The sensor...
