Purpose and application of the measuring block
The main task of the measuring block is to bridge the gap between classic measurement methods, such as stationary 4-5-gas exhaust gas analyzers, and lambda sensors mounted directly in the exhaust system.
The block is designed primarily for professional use, in combination with a dynamometer, but it can also be used as a cost-effective alternative to an exhaust gas analyzer for users with a limited budget.
Working principle and advantages
The design of the block is designed to ensure uniform measurement conditions over the entire engine speed range.
The most important and key advantage of its use is the stabilization of gas flow, temperature and pressure:
-
pressure waves, occurring, for example, in low-speed V2 engines,
are converted into a stable, uniform flue gas flow, -
dynamically changing temperature, typical for measurements in “open loop” systems,
It is stabilized to a constant, low temperature.
This creates a stable measuring environment, similar to the “closed loop” conditions for which lambda sensors are designed.
