The paper deals with a procedure for measuring the composition of blowby gas in the engine crank case by means of a conventional NDIR (Non-Dispersive Infra-Red) exhaust gas analyzer. This paper aims to evaluate the exhaust gas portion, as well as the fuel and water vapor fraction in the raw blowby gas. Determination of the exhaust content in the blowby gas is based on CO2 concentration measurement. The measurement results of several SI engines are statistically reviewed regarding the engine operational points. The influence of different operational conditions and used fuel type is shown on raw blowby gas composition in port injection SI engines.
