仪器简介：

Specific legislation relating to the emission of pollutants from the exhaust fumes of internal combustion engines has already been introduced in many countries and the areas where controls are exercised are spreading. The main pollutants to be dealt with are carbon monoxide (CO), a wide range of hydrocarbons (HC) and various oxides of nitrogen (NOX). These may be removed from the exhaust of an engine by the use of a ‘catalytic converter’ such as that contained in the Cussons P7510 Exhaust Catalytic Reactor Unit.

The concentrations of CO, HC and NOX emitted from an engine are dependant on many factors which include basic engine design, the load speed condition of the engine and the air/fuel ratio (hence ‘l’ the equivalence ratio). The efficiency. of a ‘catalytic converter’ in reducing the levels of the above pollutants is dependent on variables such as exhaust gas temperature and ‘l’, and the P7510 enables a wide range of investigations of the catalyst behaviour to be undertaken since there are built in monitoring and temperature determination facilities.

技术参数：

Exhaust Catalytic Reactor Unit suitable for fitting in the exhaust systems of diesel and spark ignited, (not using leaded petrol), engines. Fabricated in steel and containing a specially treated ceramic honeycomb monolith coated with a precious metal preparation, together with sampling points for the analysis of exhaust gas prior to, and after passing over the monolith. Fitted with three thermocouple probes for temperature sensing before and after the catalyst temperature. Complete with temperature monitoring system (P8025 with 5m of compensating cable P8028).

主要特点：

¨ Ability to operate the catalyst converter in ‘oxidising’, ‘reducing’, or ‘three way action modes’ 
¨ Steel fabrication and containing a specially treated ceramic honeycomb monolith coated with a precious metal preparation 
¨ Three thermocouple probes 
¨ Temperature monitoring system
