Description
  • Byly stanoveny emise CO, HC, NOx, a organických sloučenin (těkavé uhlovodíky, aldehydy a polyaromáty) produkované motorem Š 1.4 MPI splňujícím limity předpisu Euro 3. Emisní testy s tímto motorem instalovaným na zkušební stolici byly provedeny při vybraných ustálených provozních režimech. Při velkém zatížení pracoval motor s velmi bohatou směsí (? = 0,80 0,91), což mělo za následek velmi vysoké emise CO. Zdá se, že takové chování je běžné pro řídící jednotky motorů s malým obsahem, pravděpodobně proto, aby chránily startovací katalyzátor umístěný blízko za sběrné potrubí výfukových plynů. Ačkoli automobily vybavené těmito motory splňují příslušné emisní limity (např. EHK 83, Euro 4), jejich emise CO při velkém výkonu, který je někdy potřebný zejména na rychlostních komunikacích, mohou být řádově větší. (cs)
  • 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.
