Problems solved by technology

However, using vegetable oil as a new type of fuel for internal combustion engines, due to the high freezing point, when the temperature is low, vegetable oil will solidify and affect the normal oil supply of the oil circuit. This is also an important problem for using vegetable oil as fuel for internal combustion engines.

Embodiment Construction

[0012] A kind of vegetable oil fuel internal-combustion engine as shown in Figure 1, in the water tank 1 of internal-combustion engine, be provided with the oil pipe 3 that two ends communicate with oil tank and body 2 respectively, oil pipe 3 pipe layout form is non-linear, can be spiral or S-type; There is a gas return pipe 4, one end of the gas return pipe 4 communicates with the air outlet 6 on the respirator 5 of the internal combustion engine, and the other end communicates with the intake pipe 8 connected to the cylinder head 7 of the internal combustion engine, and a pair of inlet pipes is provided in the cylinder head 7. The glow plug 9 heated by the gas of the combustion chamber and the vegetable oil has a filter screen 10 for exhaust gas filtration inside the respirator 5, and the filter screen 10 can adopt a metal wire ball.

[0013] During work, the vegetable oil in the oil pipe 3 carries out heat exchange with the hot water in the water tank 1 when passing through...

Abstract

The invention relates to a combustion engine, especially relates to a vegetable oil fuel combustion engine. An oil pipe with two ends respectively communicating with the oil tank and the engine block is arranged in the water tank of the combustion engine; with an air back flow pipe, one end of the air back flow pipe is communicated with the upper air outlet of the breathing apparatus of the combustion engine, the other end is communicated with the air inlet pipe connecting to the cylinder cover of the combustion engine; a glow plug for heating the vegetable oil and the air entering into the combustion chamber is arranged in the cylinder cover; a filter screen for filtrating discharged air is provided inside the breathing apparatus. The invention takes the vegetable oil as fuel of the combustion engine to slowly reduce energy sources tension problem, meanwhile, using the vegetable oil combustion is also economical with environmental protection; local structure of the combustion engine is improved to increase the fluidity of the vegetable oil and ensure normal pulverization of the fuel in the working process, in addition, the reuse of the discharged air replaces the direct external discharge of the air discharged from the engine block breathing apparatus by the combustion engine to avoid environmental pollution caused by the discharged air of the combustion engine.

Description

technical field [0001] The invention relates to an internal combustion engine, in particular to a vegetable oil fuel internal combustion engine. Background technique [0002] At present, the fuel oil commonly used in internal combustion engines is diesel, which will produce more smoke during the combustion process, causing certain pollution to the environment. In addition, petroleum is a short-term non-renewable energy source. Fuels, long-term use, will inevitably cause energy shortages. In order to solve the heavy pollution of diesel as fuel and actively seek new energy sources, vegetable oil has been developed as fuel for internal combustion engines. Vegetable oil will not pollute the environment after burning. At the same time, vegetable oil is a renewable energy source with sufficient reserve reserves, which can effectively mitigate The energy shortage crisis that may arise in the future. However, vegetable oil is used as a new type of fuel for internal combustion engi...
