Embodiment 1
[0045] Such as figure 1 As shown, the present invention is a fuel preparation and supply system for an active pre-chamber, including a conventional fuel supply system and a fuel-air mixture preparation and supply system. A conventional fuel supply system includes a fuel tank 1, a fuel pipeline, a low-pressure fuel pump 3, a high-pressure fuel pump 10, a second fuel injector 11, a combustion chamber 12, and a fuel tank check valve 13. The fuel-air mixture preparation and supply system includes a fuel tank 1 , Fuel pipeline 2, low-pressure oil pump 3, first fuel injector 4, pre-mixing chamber 5, air pump 6, pressure regulating valve 7, gas nozzle 8, pre-chamber spark plug 9, combustion chamber 12.
[0046] The above design scheme can already complete the preparation and supply of fuel for the active pre-combustion chamber. Based on this scheme, the optimal scheme is given:
[0047] The premix chamber 5 is equipped with a premix chamber intake check valve 15 to ensure that there...
Embodiment 2
[0052] Such as figure 2 As shown, the present invention is a fuel preparation and supply system for an active pre-chamber, including a conventional fuel supply system and a fuel-air mixture preparation and supply system. A conventional fuel supply system includes a fuel tank 1, a fuel pipeline, a low-pressure fuel pump 3, a high-pressure fuel pump 10, a second fuel injector 11, a combustion chamber 12, and a fuel tank check valve 13. The fuel-air mixture preparation and supply system includes a fuel tank 1 , Fuel pipeline, low-pressure oil pump 3, first fuel injector 4, air pump 6, pressure regulating valve 7, gas nozzle 8, pre-chamber spark plug 9, combustion chamber 12, pre-chamber check valve 16.
[0053] The fuel tank 1 has a certain cavity to ensure that when the fuel tank is filled with oil, the fuel injector can spray oil mist into the cavity. The pre-chamber spark plug 9 is a spark plug with a pre-chamber structure. And a pre-chamber check valve 16 is installed on t...
Embodiment 3
[0055] Such as image 3 As shown, the present invention is a fuel preparation and supply system for an active pre-combustion chamber, including a conventional fuel supply system and a second fuel gas preparation and supply system. A conventional fuel supply system includes a fuel tank 1, a fuel pipeline, a low-pressure oil pump 3, a high-pressure oil pump 10, a second fuel injector 11, a combustion chamber 12, and a fuel tank check valve 13. The second fuel gas fuel preparation and supply system includes a gas bottle 2 (specifically, high-pressure gas cylinder / liquefied gas cylinder can be used), pressure regulating valve 7, gas nozzle 8, pre-mixing chamber 5, air pump 6, another pressure regulating valve 7, another gas nozzle 8, pre-combustion chamber spark plug 9, Combustion chamber 12, premix chamber intake check valve 15, pre-combustion chamber check valve 16.
