Nitration

Definition:

Nitration indicates excessive "blow-by" from cylinder walls and/or compression rings. It also indicates the presence of nitric acid, which speeds up oxidation. Too much disparity between oxidation and nitration can point to air to fuel ratio problems. As oxidation / nitration increases, so will total acid number and viscosity, while total base number will begin to decrease. Nitration is primarily a problem in natural gas engines.

Standard Test Method Used:

FTIR - ASTM E2412

Reporting Measurement:

abs/cm (absorbance units per centimeter

Amount of Sample Needed:

40 mL

Test Limitation:

Significant contamination of water, glycol, soot or fuel may affect all FTIR results.
