Zaradi obilice dela, hitrega tempa v življenju, nenehnih pritiskov glede tega, kdaj bo delo končano itd., je upravljanje s časom postala pomembna vrlina vsakega posameznika. Danes se že večina ljudi srečuje s prekomernim stresom. Sprašujemo se, kako se organizirati, kako pravilno načrtovati, kako na ...

A pure tire pyrolysis oil produced from waste tires was utilized in a modern 4-cylinder, turbocharged and intercooled, automotive Diesel engine. Due to its low cetane number, cetane improvers, external energy addition or increased compression ratios are generally required for its use in Diesel engin ...

Tire pyrolysis oil (TPO) represents a promising waste-derived fuel for Diesel engines with its main deficiency being lower cetane number compared to Diesel fuel. Until now, successful utilization of the TPO in Diesel engines was possible only by increasing its cetane number, increasing compression r ...
