    Abstract: A gas oil composition for motor vehicles, with a sulfur content lower than 0.2% by weight and with a content of aromatic hydrocarbons lower than about 30% by weight, contains, as a lubricity improver agent, an amount of from 100 to 10,000 ppm (parts per million parts by weight) of lower (C.sub.1 -C.sub.5) alkyl esters of a mixture of saturated and unsaturated C.sub.12 -C.sub.22 fatty acids, derived from vegetable oleaginous seeds.

    Abstract: A fuel filter assembly that provides a constant level of least restricted fuel flow through the fuel filter assembly during the useful life of the filter media by utilizing the least possible amount of filter media to provide the least possible pressure differential over the filter media while also providing a constant level of fuel additive by exposing an amount proportional to the filter media required for the least possible restricted fuel flow. The fuel filter assembly utilizes a vertically upward housing that houses a filter media and a fuel additive. The fuel level slowly rises in the housing as the filter media becomes obstructed with contaminants and as the fuel additive dissolves over the life of the filter media. The top portion of the housing is made of a transparent material so that the level of fuel level may be easily determined, thereby allowing for an accurate and simple assessment of the useful life of the filter media and the fuel additive. The housing also provides a multi-purpose aperture provided in the top of the housing to provide for removal and/or replacement of the fuel additive and venting and priming of the housing. The filter media and fuel additive are entirely fabricated from combustible materials so that both may be easily discarded without cost and environmental concerns.

    Abstract translation: 一种燃料过滤器组件，其在过滤介质的使用寿命期间通过利用尽可能少量的过滤介质在过滤介质上提供最小可能的压力差，在过滤器介质的使用寿命期间提供恒定水平的最不受限制的燃料流量通过燃料过滤器组件，同时还提供 通过暴露与最少可能的受限燃料流所需的过滤介质成比例的量的恒定水平的燃料添加剂。 燃料过滤器组件利用容纳过滤介质和燃料添加剂的垂直向上的壳体。 当过滤介质被污染物堵塞并且燃料添加剂在过滤介质的使用寿命期间溶解时，燃料水平在壳体中缓慢上升。 壳体的顶部由透明材料制成，从而可以容易地确定燃料液位的水平，从而允许对过滤介质和燃料添加剂的使用寿命进行准确和简单的评估。 壳体还提供设置在壳体的顶部中的多用途孔，以提供燃料添加剂的移除和/或更换以及壳体的排气和起动。 过滤介质和燃料添加剂完全由可燃材料制成，因此两者都可以容易地被丢弃，而不会造成成本和环境问题。

    Abstract: A method of deeply desulfurizing a fossil fuel which contains a variety of organic sulfur compounds, some of which are labile to hydrodesulfurization (HDS) and some of which are refractory to HDS, comprising the steps of (a) subjecting the fossil fuel to HDS or a similar method of desulfurizing labile organic sulfur compounds, and b) subjecting the fossil fuel to biocatalytic desulfurization (BDS) using a biocatalyst which is capable of selectively liberating sulfur from HDS-refractory organic sulfur compounds. In this manner, a fossil fuel is produced which does not generate sufficient levels of hazardous, sulfur-containing combustion products that it requires post-combustion desulfurization when it is burned. Moreover, the deeply desulfurized fossil fuel can be produced using only a mild HDS treatment, rather than requiring conditions which may be severe enough to be detrimental to the fuel value of the desired product. The biocatalyst employed in the BDS stage of the instant invention is capable of catalyzing the sulfur-specific, oxidative cleavage of organic carbon-sulfur bonds in sulfur-bearing aromatic heterocyclic molecules such as dibenzothiophene. A particularly preferred biocatalyst is a culture of Rhodococcus rhodocrous bacteria, ATCC No. 53968 or its active lysate, extract, fraction or subfraction.

    Abstract: A fuel/lubricant supply system for a two-cycle engine having a tank that is divided by an internal wall into a lubricant reservoir portion and fuel reservoir portion. An arrangement is provided for transferring a metered amount of lubricant from the lubricant reservoir portion into the fuel reservoir portion in response to the signal transmitted from a sensing device that senses the amount of fuel added to the fuel reservoir portion.
