912ULS發(fā)動(dòng)機(jī)
In comparison to the 80 hp version of the Rotax 912 series the 100 hp product line offers more power while keeping the weight. This engine series offers a time between overhauls of 2.000 hrs and the best power to weight ratio in its class - no surprise that this engine is the best selling 4-stroke engine. This series is available as non-certified (Rotax 912 ULS) and certified engine (Rotax 912 S) according to FAR33.
相比Rotax 912系列80馬力的發(fā)動(dòng)機(jī)，100馬力發(fā)動(dòng)機(jī)產(chǎn)品線在保持重量的同時(shí)能夠提供更大的動(dòng)力。該發(fā)動(dòng)機(jī)系列能夠提供大修間隔時(shí)間2000小時(shí)和在它的級(jí)別上提供最好的動(dòng)力重量比率。這一點(diǎn)對(duì)于一款銷量最好的4沖程發(fā)動(dòng)機(jī)來說是毫無疑問可以做到的。這個(gè)系列根據(jù)FAR33存在兩款發(fā)動(dòng)機(jī)：未認(rèn)證的Rotax 912 ULS發(fā)動(dòng)機(jī)和已認(rèn)證的Rotax 912 S發(fā)動(dòng)機(jī)。
