Exhaust gases measurement preparation

The paper deals with the measurement preparation for the exhaust gases measurement. The measurement is carried out within the project of basic research. The aim of the project is the research of the influence of an unconventional charging intercooling on the selected ecological and economical parameters of a turbocharged compression ignition internal combustion engine in the specific operational conditions. The paper gives the information about the types, numbers, specification and position of the sensors used. The measuring scheme with the connection of sensors and connector blocks is also shown. The details about the single parts of the measuring chain are given. The paper also shows the view on the sensors through the photographs. Some results from a testing measurement are also shown and the results from the selected sensors can be compared. The two different intercoolers are used for charging air cooling. The first intercooler is the air/air type equipped with a ventilator, the second intercooler is the water/air type without a ventilator. The total displacement of an engine is 7.61. The measurement itself is aimed mainly to acquire information regarding the influence of the low temperatures of charging on the amount of NOx. Also the influence on the amount of particulate matter is examined through the mentioned measurement.
