1、自然吸氣：活塞運動(dòng)自然吸氣。適用范圍，單缸機及大多數燃氣機

1. Naturally aspirated: piston movement naturally aspirates. Applicable scope, single cylinder engines and most gas engines

2、渦輪增壓：利用煙氣渦輪增加進(jìn)氣量，強制進(jìn)氣。適用范圍：大多數柴油發(fā)電機組及部分汽油機。

2. Turbocharging: Using a flue gas turbine to increase the intake volume and force intake. Scope of application: Most diesel generator sets and some gasoline engines.

3、增壓中冷：空氣中冷器加渦輪增壓。

3. Supercharged intercooler: an air intercooler with turbocharging.

沼氣發(fā)電機組保養和維護相對于柴油機的特別之處：基本的保養和維護都同于相對應柴油機組，下面特別指出燃氣機組變動(dòng)后的特別保養和維護部分：本機組中為了適應天然氣或沼氣的燃燒有兩個(gè)主要的改進(jìn)，一是使天然氣或沼氣與空氣按合適的比例良好混合；二是將混合氣及時(shí)有效點(diǎn)燃而高效做功。

The special aspects of maintenance and upkeep of biogas generator sets compared to diesel engines are as follows: basic maintenance and upkeep are the same as those of corresponding diesel sets. The special maintenance and upkeep parts after the change of gas sets are specifically pointed out: In this unit, there are two main improvements to adapt to the combustion of natural gas or biogas, one is to mix natural gas or biogas well with air in an appropriate proportion; The second is to ignite the mixture in a timely and effective manner to efficiently perform work.

1、為了保證絕對安全，天然氣發(fā)電機組機房應遠離明火區域；

1. To ensure absolute safety, the natural gas generator room should be kept away from open flame areas;

2、做好室內安裝照明、開(kāi)關(guān)、線(xiàn)路及其電器應的防爆措施；

2. Take explosion-proof measures for indoor installation of lighting, switches, circuits, and electrical appliances;

3、完善消防措施，配備滅火器等消防器械；

3. Improve fire protection measures and equip fire extinguishers and other fire-fighting equipment;

4、燃氣發(fā)電機組機房?jì)劝惭b可燃氣體報警裝置，可燃天然氣發(fā)電機組氣體泄露時(shí)能及時(shí)發(fā)現。

4. Install combustible gas alarm devices in the gas generator room, which can detect gas leaks in a timely manner when the combustible natural gas generator set is leaking.

5、好選擇寬敞、明亮且要求安裝換氣扇以保證良好的通風(fēng)，有助機組的使用；

5. Choose spacious, bright and require the installation of ventilation fans to ensure good ventilation, which is helpful for the use of the unit;

6、天然氣發(fā)電機組安裝時(shí)底盤(pán)與地基應用平墊鐵找平，接觸面積應在60%以上，且分布均勻。

6. When installing natural gas generator sets, the chassis and foundation should be leveled with flat iron pads, and the contact area should be over 60% and evenly distributed.
