Taiyuan car manufacturers, wholesale Taiyuan, where urea urea selling car

 Car Taiyuan Taiyuan, where urea manufacturers, wholesale car urea urea manufacturers sell wholesale vehicles Taiyuan Taiyuan, where car selling cars urea urea its high compression ratio and deposit is higher than gasoline fuel frequency, because it exists being excellent fuel economy, energy, persistence and broad use on passenger truck. Diesel vehicles HC, CO, CO2 than gasoline vehicles ranked as low as possible, and can be used as bio-diesel and other best use balcony new impetus, and thus the future of diesel vehicles using very good. However, diesel vehicles emit NOx (nitrogen oxides) and PM (particulate matter) is much higher than gasoline vehicles, and the helpless such as gasoline vehicles using three-way catalyst to reach the country Ⅳ emissions, limit the use of urea stalled car. NOx can form photochemical smog and acid rain, toxic effect of deposit is eroded, sulfur oxides and nitrogen oxides lead to minor precisely the spirit of acid rain, acid rain prevention and control of the situation after the match seriously, and nitrogen oxides are proof of this stage Control power point. PM (particulate matter) for human breathing piecemeal great damage, can cause acute lung disease or cancer. PM minor components from solid soot, soluble inorganic salt * all three components. Its emissions of particulate soluble inorganic deposit is mutagenic effects, over 90% are carcinogens. In addition, PM can also lead to human suffering from acute lung disease. Because vehicle emissions of particulate urea particle size is small, the statistics indicate 90% material (quality percentage) over the particles are smaller than lμm, the department stopped particles suspended in the atmosphere for a long time, so it increases the chance of exposure to the human body, but also increase the opportunity to participate in the air particles are other chemical reactions of. Forming a haze of fine particles is minor reason, because rapid increase in vehicle population, resulting in rapid increase in motor vehicle emissions, the atmosphere of this accumulation of fine particles PM2.5 on more and more, thereby forming a gray haze match repeatedly. Thus vehicle urea NOx and particulate emissions for all mankind debilitating and damaging effects of atmospheric conditions exist is no capacity overvalued, which restricts 柴油启 motivation stagnation. Capitals community's efforts to reduce vehicle emissions of NOx and PM urea study, its road fuel quality has improved after the implementation of the machine skills and mutton air pollution solving skills. However, a small number of experimental study] demonstrated the machine only rely on the skills simultaneous increase pollution emission of NOx and PM emissions as much as possible to request consistent regulations have become more and more difficult and lead to lower consumption and the use of profits apparently. Thus vehicle within urea contamination solve simultaneous assistant to throttle the gas after solving skills to grasp the spirit of vehicle emissions harmless urea urea future changes in vehicle standstill position. Light prosperous country based bus stagnation experienced after the minor has two mutton gas after solving skills roads: one is the EGR + DPF / DOC (wastewater repeat piecemeal + particulate filter / oxidation catalytic converter) road, After that first turn off water to repeat the process of increasing the amount of NOx generated, and then through a particle trap trapping skills due to the adoption of EGR slightly increased particulate matter, simultaneous air oxidation catalytic converter with current recycling particulate trap ; the other is optimized extinguish + SCR road, that is optimized to extinguish increased emissions of particulate matter, NOx production simultaneous promise has increased, and then through the choice of rehabilitation skills to increase NOx catalytic exhaust extinguished due to optimization occurs as to reach the simultaneous rise of the effectiveness of NOx and PM. Eyes, their large diesel vehicles are logistics and trafficking in contrast to declining share of its economy than in Africa using high 5% to 10%. EGR SCR Skill Skill saving 5% -7%, thus saving from an economic standpoint, SCR skills are appropriate to their national conditions of a large car with urea energy saving skills road.
