摘要: Abstract of EP0640680This invention relates to a two-stroke engine oil which comprises polybutene base oils are either very low in or substantially free n-butenes the polymer backbone. The absence polybutenes significantly reduces smoke emission exhaust gases generated by use oil. Polybutenes such as ULTRAVIS TM chlorine and have high degree terminal unsaturation particularly preferred.
