Název v původním jazyce

Skoda 1.4 engine exhaust emission in relation to its operational mode

Popis výsledku v původním jazyce

Emissions of CO, HC, NOx, and organic compounds (aldehydes, volatile hydrocarbons, and polyaromatics) were measured on Euro 3 1400 ccm SI engine using test brake stand at varied engine conditions (speed, load). At high load conditions, the engine operated with very rich fuel mixture (? = 0.80 0.91), which resulted in very high CO emissions. Such behavior seems to be common for some recent engine control units, especially for low displacement engines, probably due to the protection of starter catalyst placed directly at engine exhaust manifold. Although cars equipped with these engines can meet emission limits (e.g. ECE 83, Euro 4), their CO emissions at high load, especially in highway traffic, can rise by order of magnitude.new catalyst and after mileage 20, 40, 60, 80 and 100 thousands kilometers. HC, CO, and aldehyde emissions produced by the engine equipped with KARSIT converter were markedly lower than those produced by the engine equipped with ECOS converter. The efficiency of KA
