Multi-fuel fuel oil supply device

Abstract

The invention provides a multi-fuel fuel oil supply device. The multi-fuel fuel oil supply device comprises a fuel oil tank, a fuel oil delivery pump, a fuel oil filter, a fuel oil return pipe, a high-pressure oil pipe, a high-pressure air guide pipe, a compressed air nozzle, an air compressor, an electronic control air-fuel mixture injector, an electronic control unit, a sensor, an air cylinder and a high-energy ignition sparking plug. The high-pressure oil pipe and the compressed air nozzle are connected to the electronic control air-fuel mixture injector. The electronic control air-fuel mixture injector is fixed to the top of a cylinder cover of the air cylinder. The high-energy ignition sparking plug stretching into the air cylinder is installed on one side of the electronic control air-fuel mixture injector. The electronic control air-fuel mixture injector and the compressed air nozzle are both electrically connected with the electronic control unit. According to the multi-fuel fuel oil supply device, the compact design of an engine is facilitated, it is guaranteed that the working process of a system is stable, combustion is complete, the fuel oil utilization rate is high, the mean effective pressure is increased, the power output level of the engine is increased, and the specific mass level of a whole machine is increased.

Description

technical field [0001] The invention belongs to the field of engine fuel supply system manufacture, and in particular relates to a multi-fuel fuel supply device. Background technique [0002] With the development of UAV technology, higher requirements are put forward for the power system, especially the engine technology. For UAV systems used in specific fields (such as ship-borne UAV systems), conventional gasoline engines cannot meet the unified management of fuel oil, the safety and fuel economy requirements of oil transportation and storage. [0003] Diesel or heavy oil fuel engines can meet the above requirements, but for aviation power, conventional compression ignition diesel engines have a large specific mass, which has a great impact on the weight and working load of the UAV, and are not suitable for UAV power. Contents of the invention [0004] In view of this, the present invention aims to propose a multi-fuel fuel supply device that utilizes high-energy electr...
