摘要： A method of evaluating thermal stability of a fuel and an apparatus used therein. The method includes heating the fuel to a given temperature, directing light through the heated fuel a first time wherein the light is of an intensity and of a wavelength to induce fluorescence and obtaining a first fluorescence data, directing the light through the fuel at least a second time that is later in time and obtaining a second fluorescence data, and measuring any changes to fluorescence from the heated fuel over time.

摘要： A combustor for burning the untreated exhaust of an internal combustion engine heats and burns the exhaust prior to release into the atmosphere, or prior to introduction into a downstream treatment system such as a catalytic converter. The combustor defines a novel, passive flame holder in combination with an igniter, whereby the exhaust continues to burn, without assist, once ignited. Managed air injection may be employed. The combustor is configured to fit within standard exhaust systems with a minimum of modification to the overall exhaust assembly. The combustor is particularly useful in cold start conditions for increasing the temperature of the exhaust to catalytic converter operating temperatures and for use in small engine applications where exhaust has heretofore been released untreated.
摘要翻译： 用于燃烧内燃机的未处理排气的燃烧器在排放到大气中之前或者在引入下游处理系统例如催化转化器之前加热并燃烧排气。 燃烧器限定了与点火器组合的新颖的被动火焰保持器，由此一旦点燃，排气继续燃烧，无需辅助。 可以采用管理空气喷射。 燃烧器被配置成适合在标准排气系统内，对整个排气组件进行最小的修改。 燃烧器在用于将排气温度提高到催化转化器工作温度的冷启动条件下特别有用，并且用于在未经处理的排气处于排放的小型发动机应用中。

摘要： An engine is provided which, in at least one cylinder or combustion area, is provided with a hydrocarbon rich fuel which produces upon combustion an exhaust gas containing unburned hydrocarbons, water vapor and carbon monoxide. The exhaust gas is treated in a catalytic converter and the reaction process that occurs therein produces hydrogen and carbon dioxide which is mixed with air to form a hydrocarbon lean, hydrogen enriched mixture. The mixture is subsequently ignited in other cylinders or combustion areas of the engine to produce power.

摘要： A mixture of alkoxy-terminated poly-oxymethylenes, having a varied mixture of molecular weights, is blended with diesel fuel to form an improved fuel for autoignition engines. The mixed alkoxy-terminated poly-oxymethylenes may be produced by reacting paraformaldehyde with methylal, methanol, or other alcohol for a length of time and at a temperature and pressure sufficient to form the mixed alkoxy-terminated poly-oxymethylenes. The base diesel fuel, when blended with the mixed alkoxy-terminated poly-oxymethylenes in a volume ratio of from about 2 to about 5 parts diesel fuel to 1 part mixed alkoxy-terminated poly-oxymethylenes, provides a higher quality fuel having significantly improved lubricity and reduced smoke formation, without degradation of the cetane number or smoke formation characteristics when compared with the base diesel fuel.
