    Abstract: Emissions of pollutants from diesel engines (10) are reduced by a regimen for catalytically treating engine exhaust and, preferably, also the combustion of the fuel. The balance point of a diesel trap (30) is reduced to permit more efficient regeneration, preferably self-regeneration, while also reducing emissions of carbon monoxide and hydrocarbons by a combination of mechanical devices and fuel additives. The regimen requires the introduction of from 0.05 to 1 ppm of a platinum group metal catalyst (based on the volume of fuel combusted) into the particulates, by introducing at least half of the platinum group metal catalyst (50) directly into the hot exhaust gases (52, 20). Preferably, the platinum group metal catalyst is employed with a combustible organic liquid to aid in either progressively loading the trap (30) with the combustible organics or to combust in the hot combustion gases to facilitate burning of the particulates on the trap (30) for more effective regeneration. The judicious selection and use of an auxiliary catalyst metal (e.g., copper), preferably adding at least half of its total to the fuel as a fuel additive, is a preferred part of the regimen to achieve the lowest trap balance point.

    Abstract translation: 来自柴油发动机（10）的污染物的排放通过用于催化处理发动机排气的方案减少，并且优选地还被燃料的燃烧。 柴油收集器（30）的平衡点被减少以允许更有效的再生，优选自再生，同时还通过机械装置和燃料添加剂的组合减少一氧化碳和烃的排放。 该方案需要将0.05至1ppm的铂族金属催化剂（基于燃烧的燃料的体积）引入颗粒中，通过将至少一半的铂族金属催化剂（50）直接引入热废气中 （52,20）。 优选地，将铂族金属催化剂与可燃有机液体一起使用以帮助将捕集器（30）逐渐加载到可燃的有机物上，或者在热燃烧气体中燃烧，以便于将微粒燃烧在捕集器（30）上 更有效的再生。 辅助催化剂金属（例如铜）的合理选择和使用，优选将其总量的至少一半添加到作为燃料添加剂的燃料中，是实现最低陷阱平衡点的方案的优选部分。
