1、沼气发电机组的曲柄连杆机构是发动机实际工作周期中完成能量转换的主要运动部件。 由机体组、活塞连杆组、曲轴飞轮组等组成。 在工作过程中，活塞受到气体的压力，在气缸内进行直线运动，通过连杆转换为曲轴的旋转运动，从曲轴向外部输出动力。 另一方面，在吸气、压缩和排气过程中，飞轮释放能量，将曲轴的旋转运动转换为活塞的直线运动。

1. The crank connecting rod mechanism of a biogas generator set is the main moving component that completes energy conversion during the actual working cycle of the engine. Composed of a body assembly, piston connecting rod assembly, crankshaft flywheel assembly, etc. During the working process, the piston is subjected to gas pressure and moves in a straight line within the cylinder. It is converted into the rotational motion of the crankshaft through the connecting rod, outputting power from the crankshaft to the outside. On the other hand, during the suction, compression, and exhaust processes, the flywheel releases energy, converting the rotational motion of the crankshaft into linear motion of the piston.

2、沼气发电机组配气机构配气机构的作用是根据发动机的工作顺序和工作过程，定时开关进气阀和排气阀，使可燃混合气或空气进入气缸，废气从气缸内排出，实现通风过程。 配气机构大多采用顶置阀式配气机构，一般由阀单元、气门单元、气门驱动单元构成。

2. The function of the gas distribution mechanism of the biogas generator set is to regularly open and close the intake and exhaust valves according to the working sequence and process of the engine, allowing combustible mixture or air to enter the cylinder, and exhaust gas to be discharged from the cylinder, achieving the ventilation process. Most valve mechanisms use overhead valve type valve mechanisms, which are generally composed of valve units, valve units, and valve drive units.

3、沼气发电机组燃油供给系统汽油机燃油供给系统的作用是根据发动机的要求配制一定量和浓度的混合气，提供给气缸，燃烧后的废气从气缸内向大气排放，柴油机燃油供给系统的作用是将柴油和空气分别提供给气缸沼气发电机

3. The fuel supply system of the biogas generator set is used by the gasoline engine to prepare a certain amount and concentration of mixed gas according to the requirements of the engine, which is supplied to the cylinder. After combustion, the exhaust gas is discharged into the atmosphere from the cylinder. The function of the diesel engine fuel supply system is to provide diesel and air to the cylinder biogas generator separately

4、沼气发电机组润滑系统润滑系统的作用是给做相对运动的零件表面输送定量清洁的润滑油，实现液体摩擦，减少摩擦阻力，减轻零件磨损，清洗、冷却零件表面。 润滑系统通常由润滑油路、油泵、滤油器和几个阀门等组成。

4. The function of the lubrication system of the biogas generator set is to deliver a quantitative amount of clean lubricating oil to the surface of the parts in relative motion, achieve liquid friction, reduce friction resistance, reduce part wear, and clean and cool the surface of the parts. The lubrication system usually consists of a lubricating oil circuit, an oil pump, an oil filter, and several valves.

5、沼气发电机组冷却系统冷却系统的作用是将受热部件吸收的部分热量及时散热，保证发动机在适合温度下工作。 水冷发动机的冷却系统通常由冷却水套、水泵、风扇、水箱、恒温器等组成。

5. The function of the cooling system of the biogas generator set is to timely dissipate the heat absorbed by the heated components, ensuring that the engine operates at a suitable temperature. The cooling system of a water-cooled engine usually consists of a cooling water jacket, water pump, fan, water tank, thermostat, etc.

6、沼气发电机组点火系统所有能在火花塞电极之间按时产生火花的设备均为点火系统。 在汽油发动机中，气缸内的可燃混合气由火花点火。 因此，在汽油发动机的气缸盖上安装了火花塞，火花塞的头部深入燃烧室内。 点火系统通常由电池、发电机、分电器、点火线圈、火花塞等构成。

6. All devices that can generate sparks on time between the spark plug electrodes in the ignition system of biogas generator sets are ignition systems. In gasoline engines, the combustible mixture in the cylinder is ignited by a spark. Therefore, spark plugs are installed on the cylinder head of gasoline engines, and the head of the spark plug penetrates deep into the combustion chamber. The ignition system usually consists of a battery, generator, distributor, ignition coil, spark plug, etc.

7、沼气发电机组起动系统发动机从静止状态过渡到工作状态，先须通过外力旋转发动机曲轴，使活塞往复运动。 气缸内可燃混合气燃烧膨胀做功，只有压下活塞带动曲轴旋转，发动机才能自转，工作循环自动进行。 因此，从曲轴因外力开始旋转到发动机自动开始怠速运转的全过程称为发动机起动。 完成起动过程所需的装置称为发动机的起动系统。 汽油机由曲柄连杆机构、配气机构、燃烧供给系统、润滑系统、冷却系统、点火系统、起动系统两个机构和五个系统构成;柴油发动机由曲柄连杆机构、配气系统、燃料供给系统、润滑系统、冷却系统、起动系统两个机构和四个系统构成，柴油发动机为压缩燃烧，不需要点火系统。

7. The starting system of a biogas generator set requires the engine to transition from a stationary state to a working state by first rotating the engine crankshaft through external force, causing the piston to move back and forth. The combustion and expansion of the combustible mixture in the cylinder do work. Only by pressing the piston to drive the crankshaft to rotate can the engine rotate and the working cycle automatically proceed. Therefore, the entire process from the crankshaft rotating due to external force to the engine automatically starting to idle is called engine starting. The device required to complete the starting process is called the engine's starting system. A gasoline engine consists of two mechanisms and five systems: a crank connecting rod mechanism, a valve distribution mechanism, a combustion supply system, a lubrication system, a cooling system, an ignition system, and a starting system; A diesel engine consists of two mechanisms and four systems: a crank connecting rod mechanism, a valve distribution system, a fuel supply system, a lubrication system, a cooling system, and a starting system. The diesel engine is a compression combustion engine and does not require an ignition system.
