Reducing the emission indexes of the internal combustion engine with a catalyst converter
In the article the results of the car research with a prechamber engine and an exhaust gas catalyst converter are presented that carried out as a block test with chassis dynamometers according to EU test cycle phases. They testify that during the first “cold” phase of the test cycle the total harmful emissions in exhaust gases contain more then 70 % of the whole cycle carbon monoxide and more then 45 % of the whole cycle hydrocarbons. To reduce harmful emissions in exhaust gases at the engine cold start the hydrogen injection to the catalyst converter is offered, that allows the content of carbon monoxide and nitric oxide in exhaust gases be reduced by more then 98 % and the hydrocarbons content – by more then 80 %.
