Chap. I - Gas Analyser
Gas-manual-en.docx — 4 —
The gas analyser is a four-part (optional five-part) analyser of exhaust gases, to be used for measurement and
adjustment of petrol, LPG, and CNG engines, and for controlling emissions of those engines according to relevant
national regulations. It can measure HC, CO, CO
2
, O
2
, and NO
X
concentrations, and calculate CO
cor
and the
coefficient of air redundancy λ from those values. Furthermore, it measures engine speed and oil temperature for
use during statutory MoT test procedures. The measured data can be printed by the printer as partial
measurements or as an MoT test certificate.
Mechanical construction is described in Chap. I - 5.
