Understanding Engine Exhaust Emissions - Crypton

A/F ratio or Lambda = Calculated Air/Fuel Ratio or Lambda value based on the HC, CO, CO2 and O2 concentrations. Remember the ideal (Stoichiometric) A/F is liters air to 1 liter fuel or /1. The ideal Lambda value is 1(one) below that the A/F mixture is rich and above - lean. For example, lambda= corresponds to an air/fuel ratio of ():1=:1 ( lambda = A/F ratio ...

List of Instruments in Measuring Emission | It Still Runs

These instruments test and measure the amount of engine exhaust for specific gas components, including CO, CO2, NO, HC and oxygen. Equipment is first calibrated using ambient air prior to each use to ensure accurate measurements. Analyzers feature a sample line to collect exhaust gases and a two-stage filter system that is capable of detecting and capturing both large and small particles ...

Fehler CO-Sensor bei ecoTEC exclusive VC146 ...

· Fehler CO-Sensor (7) oder Notbetrieb aktiv. Im Netz bin ich auf Beiträge gestoßen, wo der gleiche Fehler bestand. Nur wurde da auch mal beschrieben, das es bei sich bei Ihnen nicht um einen defekten Sensor sonder um eine defekte Leiterplatte gehandelt hat. Also muss es sich praktisch nicht immer um den Sensor handeln.

Lambdasonden Teil 1 - Kfz-Tech

das HC mit dem Sauerstoff zu CO 2 und H 2 O umgewandelt (Oxydation), die Stickstoffoxyde NO x zu Stickstoff N 2 und O 2 umgewandelt (Reduktion). Die beste Reduzierung aller 3 Schadstoffe kann der Katalysator aber nur dann erzielen, wenn sich das Gemisch im Bereich von Lambda 1 (Lambdafenster 0,98-1,01) befindet. Die optimale Abgaszusammensetzung kann nur durch eine elektronische …

Car Exhaust Gas Analyzer Chart | Walker Exhaust Systems

The low HC and CO readings indicate that the converter is functioning. The root cause of the problem is an engine which is emitting excessively high NOx emissions. These high NOx emissions may reduce the durability and efficiency of the converter . Typical gas analyzer readings; Readings that would indicate a properly functioning engine and converter (at idle) CO2. - 16%. o2. 0 - .35%. CO ...

Why do I have CO2 sensor failure, but don't have one ...

If yes continue to the next step, If no replace the RTEM and jump to end. 3. It looks like you do have a CO2 sensor installed. Check DC voltage across the two DCV pins (with wires still attached). If you measure 0VDC (short) or 10VDC (open) then you should verify proper wiring. If wiring is correct then replace the CO2 sensor.

exhaust - Failed emissions - high lambda, low HC and CO ...

The CO and HC are in the normal range, however for a 2005 car, these should be far higher. 11ppm, for example, is less than a new engine on this model of car! – Nick Dec 16 '13 at 11:19.
