Diesel engine oils的意思|示意

A further advantage is that unmodified oils from plants, like the peanut oil used by Diesel in the 19th century, have high viscosity and require engine alterations.

一个未来的好处是从植物中提取的未改变的油，像十九世纪柴油机用的花生油，有很高的粘性，需要引擎改装。

When these oils are heated, their viscosity is reduced, and they can be burned directly in a diesel engine, or the oils can be chemically processed to produce fuels such as biodiesel.

当这些植物经过加热后粘稠度降低，便可直接在柴油机内燃烧，或者将部分油类经过化学方法加工为生物柴油。

In recent years, with the improvement of heavy commercial vehicle diesel engine and increasingly strict emission regulations, there is more and more demand on the diesel engine and oils.

近年来，随着重型大功率商用车柴油机强化程度的不断提高和废气排放标准的日趋严格，对柴油机及其机油的要求越来越高。

Dr. Rudolf Diesel believed his engine would operate on a variety of vegetable oils but, as petroleum-based diesel fuel was cheaper and readily6 available, it quickly became the fuel of choice.

鲁道夫·狄塞尔相信他的发动机可以用各种各样的植物油驱动，但由于以石油为基础的柴油燃料价格更便宜且容易获取，于是柴油迅速成为发动机燃料的首选。
