The environmental pollution caused by the rapid economic development awakens people's attention to environmental protection. Gas emission is the source of pollution emission of generator set. In response to the call of environmental protection, many people in the industry have greatly improved the generator design to reduce the emission pollution. Today, jichai will talk about its own views on this issue.

瓦斯發(fā)電機(jī)組主要是通過(guò)進(jìn)氣系統(tǒng)將經(jīng)過(guò)灰塵、雜質(zhì)過(guò)濾的空氣送入氣缸內(nèi)，因此，只要對(duì)進(jìn)氣系統(tǒng)進(jìn)行改進(jìn)，控制進(jìn)入的空氣量便能有用控制燃燒后的空氣污染程度。海興動(dòng)力認(rèn)為，以下兩種方法是可行的：

The gas generator unit mainly sends the air filtered by dust and impurities into the cylinder through the air intake system. Therefore, as long as the air intake system is improved and the air quantity is controlled, the air pollution degree after combustion can be effectively controlled. Haixing power believes that the following two methods are feasible:

1、可采用可變渦流進(jìn)氣系統(tǒng)。由于進(jìn)氣渦流強(qiáng)度對(duì)NOx的排放影響較大，采用可變渦流進(jìn)氣系統(tǒng)的方式依據(jù)轉(zhuǎn)速和負(fù)荷的變化來(lái)控制渦流強(qiáng)度，可在不犧牲經(jīng)濟(jì)性的情況下降低發(fā)電機(jī)組運(yùn)行中NO。的生成量。

1. Variable swirl intake system can be used. Because the intake swirl intensity has a great influence on NOx emission, the variable swirl intake system is used to control the swirl intensity according to the change of speed and load, which can reduce the no emission in the operation of the generator without sacrificing the economy. The amount of production.

2、采用多氣門技術(shù)(通常采用每缸四氣門：進(jìn)氣門和排氣門各2個(gè))可擴(kuò)大進(jìn)、排氣門的總流通截面積，充量系數(shù)增加，且噴油器可垂直布置在汽缸軸線上，有利于燃油在燃燒室空間中均勻分布，其混合氣形成和燃燒條件大為改善，使放熱規(guī)律更為合理，尾氣排放中NOx的排放下降，CO的排放也有所減少，而且炭煙在大負(fù)荷時(shí)也明顯下降。

2. The multi valve technology (usually four valves per cylinder: two inlet valves and two exhaust valves) can enlarge the total flow area of inlet and exhaust valves, increase the charge coefficient, and the injector can be vertically arranged on the cylinder axis, which is conducive to the uniform distribution of fuel in the combustion chamber space, greatly improve the mixture formation and combustion conditions, and make the heat release law more reasonable, In the exhaust emission, NOx emission and CO emission are reduced, and soot emission is also significantly reduced under heavy load.

以上兩種方法是通過(guò)改良瓦斯發(fā)電機(jī)組技術(shù)而達(dá)到控制污染排放的目的的，而對(duì)于無(wú)法做到這一點(diǎn)的普通用戶們，仍然可以在能力范圍內(nèi)降低發(fā)電機(jī)組的污染，例如，給進(jìn)氣管噴水或乳化柴油來(lái)促進(jìn)油料的燃燒，燃燒充分的柴油所排放出的有害氣體就會(huì)減少。

The above two methods achieve the purpose of controlling pollution emission by improving the technology of gas generator set. For ordinary users who can't do this, the pollution of generator set can still be reduced within the scope of their ability. For example, spray water on the intake pipe or emulsified diesel to promote the combustion of oil, and the harmful gas emitted by fully burned diesel will be reduced.
