WebThese air dilution conditions are usually indicated by high O2 readings in the exhaust stream along with an overall reduction in the concentration of the other gases. To improve the correlation of the EGA Lambda to the Engine Management System mixture control point, air injection should be disabled, and exhaust air leaks should be corrected. WebMar 9, 2024 · Imagine you have a sample of 1 m 3 of air, with 0.0004 m 3 of carbon dioxide in the mixture: What is the PPM concentration of carbon dioxide? Starting with the “parts per part” or “parts per 1” calculation: And then multiply this by 10 6 to finish the PPM conversion: 0.0004 × 10 6 = 400 PPM. PPM Calculator and Formula WebThe air pressure drop calculation formula that can be used is expressed as: dp= 7.57q 1.85 L 10 4 / (a 5 p) Assuming: dp = pressure drop (kg/cm 2) q = air volume flow at atmospheric conditions (FAD) (m 3 /min) L= length of pipe (m) d = inside diameter (mm) p = initial pressure – gauge (kg/cm 2) geisinger authorization to release
