Description
技术领域technical field
本实用新型属于燃气发动机输送设备领域，具体涉及一种新型燃气发动机气体输送调控装置。The utility model belongs to the field of gas engine conveying equipment, in particular to a novel gas engine gas conveying control device.
背景技术Background technique
柴油机为压燃式，着火点为220℃；汽油机为点燃式，着火点为427℃；而天然气为点燃式，着火点为650℃。燃油发动机是活塞、汽缸驱动，燃气发动机是燃气喷到涡轮上，驱动转动。新鲜空气由进气道进入燃气轮机后，首先由压气机加压成高压气体，接着由喷油嘴喷出燃油与空气混合后在燃烧室进行燃烧成为高温高压燃气，然后进入涡轮段推动涡轮，将燃气的焓和动能转换成机械能输出，最后的废气由尾喷管排出。天然气发动机最大的优点是排污染低，天然气发动机不会造成润滑油稀释，能延长发动机寿命，同是还可降低汽车噪音等。但是如今的燃气发动机的输送调控管路的燃气流量控制主要通过驾驶员控制以满足汽车行驶功率的需要，但是在内燃机内压力较小而由于操作不当通入过量燃气时容易造成能源浪费，或者在压力较大而流量过小造成熄火。The diesel engine is a compression ignition type with an ignition point of 220°C; the gasoline engine is an ignition type with an ignition point of 427°C; and the natural gas is an ignition type with an ignition point of 650°C. The fuel engine is driven by pistons and cylinders, and the gas engine is driven by gas sprayed on the turbine to drive the rotation. After the fresh air enters the gas turbine from the intake port, it is first pressurized into high-pressure gas by the compressor, and then the fuel injected from the fuel injector is mixed with air and then burned in the combustion chamber to become high-temperature and high-pressure gas, and then enters the turbine section to drive the turbine, and the The enthalpy and kinetic energy of the gas are converted into mechanical energy output, and the final exhaust gas is discharged from the tail nozzle. The biggest advantage of the natural gas engine is low pollution, the natural gas engine will not cause lubricating oil dilution, can prolong the life of the engine, and can also reduce the noise of the car. However, the gas flow control of the transmission and regulation pipeline of today's gas engines is mainly controlled by the driver to meet the needs of the driving power of the car, but the pressure in the internal combustion engine is small, and it is easy to cause energy waste when excessive gas is introduced due to improper operation, or in High pressure and low flow rate cause flameout.
