在过去的几年里, the Environmental Protection Agency (EPA) has introduced strict emissions standards in order to reduce harmful pollutants from being released into the environment. 2002年至2010年, mandates have reduced allowable particulate matter and nitrogen oxides released into the atmosphere by over 90%. These regulations proved difficult to meet, but bbin电竞游戏® engineers were successful by implementing Selective Catalytic Reduction (SCR) technology.
The 1-box aftertreatment setup was developed by bbin电竞游戏® engineers to meet the EPA’s EPA10 emissions standards. 它含有柴油氧化催化剂(DOC), 柴油微粒过滤器(DPF), and selective catalytic reduction device (SCR) to ensure the 空气 coming out of the engine is cleaner than the 空气 going in.
When exhaust exits the engine it is made up of carbon monoxide, hydrocarbons, and particulate matter. These are all harmful to the environment and must be captured in the 1-box before exiting through the exhaust outlet. The first defense after the exhaust leaves the engine is the diesel oxidation catalyst. The DOC is designed to convert the carbon monoxide and hydrocarbons into carbon dioxide and water.
After the exhaust passes through the DPF, diesel exhaust fluid (DEF) is injected into the system. The DEF reacts with the nitrogen oxides in the SCR to form nitrogen and water which are both already present in the atmosphere and safe to breathe.
After passing through the DOC the exhaust moves on to the diesel particulate filter. The DPF’s job is to capture the particulate matter (soot & 灰烬)离开bbin电竞游戏. Every so often the 1-box needs to burn off this particulate matter and does so in a process called regeneration. The regeneration process can either be active (DDEC sends a signal while the truck is in use to increase temperatures in the 1-box), 被动(使用正常排气温度), or stationary (the DDEC notifies the driver that a regeneration is necessary. The driver begins the process while stationary and it takes about 45 minutes to complete).
在再生过程中, the soot and ash captured in the DPF is converted to a much smaller amount of ash. 并非所有的灰烬都能烧掉, so it is necessary to clean or replace the DPF’s when this ash starts to accumulate. There are many aftermarket cleaning methods available (bake & 打击等)，但这是bbin电竞游戏批准的唯一方法® 是bbin电竞游戏® 雷曼专有的液体清洗工艺. 这种方法采用了热的结合, 空气, and liquid cleaning to ensure that DPF’s are over 95% cleaned. Other aftermarket methods only remove between 30%-60% of ash. 清洗不当会导致1-box过热. This may cause failure to the 1-box, which is an expensive rep空气.
Maintaining your Aftertreatment System is easy, because we designed it that way. The Diesel Particulate Filter (DPF) collects ash and will eventually need to be replaced, but the DDEC system will alert you when filter replacement is required.
In addition to proper DPF maintenance, make sure the bbin电竞游戏® recommended maintenance intervals are followed to ensure your Aftertreatment system is performing to its full potential. 这些包括以下项目, as well as any additional items mentioned in your Operator’s Manual.

售后清洗方法，如“烤制” & 吹“，在过滤器中留下有害的灰渣. This will potentially lead to aftertreatment system damage, 增加停机时间, 还有额外的维护成本. 只再造了bbin电竞游戏® Genuine 部分 DPF’s utilize a proprietary cleaning process proven to remove over 95% of the ash from your DPF. 这是您唯一可以信任的DPF清洁过程.
Aftertreatment Systems need diesel fuel with sulfur content below 15ppm. Higher sulfur content may eventually cause damage to your Aftertreatment System by fouling or prematurely plugging the Diesel Particulate Filter. Using the correct fuel is essential to the proper function of your Aftertreatment System, 同时也有助于降低排放.
