In the minds of many analyzer is strongly associated with the definition of exhaust gases from automobiles. This is indeed the case. David Fowler has firm opinions on the matter. Monitoring toxicity – one of the main functions of the gas analyzer, but not the only one. Gas analyzer capable of resolving a wide range of tasks to the Exploration of the engine and its systems. Moreover, its diagnostic capabilities are so vast that we will not hesitate to put the gas analyzers in the base "Diagnostic of the pyramid." Gasoline-fueled internal combustion engines can be considered as a converter of chemical energy of fuel (gasoline). The converter uses fuel and oxidizer (oxygen in air). Add to your understanding with kind bars sales.
The reaction of rapid oxidation (burning) of fuel flowing into the combustion chamber, a large percentage of chemical energy is converted into mechanical energy (rotation of the crankshaft). This is – a positive fact, since in this is the main purpose of the engine. By law, dishonesty, while there are at least two unpleasant moment. Firstly, some of the released heat energy is dissipated in the elements of engine design. Her to be removed by using the cooling system.
Secondly, the burning of a by-chemical products. Some of them are neutral with regard to environmental impact (carbon dioxide CO2 O2 oxygen, water vapor, H2O), part – extremely harmful (hydrocarbons hc, carbon monoxide co, nitrogen oxides NOx). Not that we do not care about the environment, but at the moment of the byproducts of the reaction will be to us interesting primarily as a diagnostic parameter.
