Abstract

A fuel oil engine, a driving apparatus thereof and a working method. Mixed fuel gas of fuel oil and air in the driving apparatus burns in a master cylinder body (310) so as to drive a first piston (320) to move and enable a main cylinder to do work. Meanwhile, air in an auxiliary cylinder body supercharges into the master cylinder body through a two-way valve. In addition, residual fuel gas after burning of the mixed fuel gas in the main cylinder body after supercharging is complete enters the auxiliary cylinder body through the two-way valve so as to drive a second piston to move and enable an auxiliary cylinder to do work. Thus, fuel efficiency of the engine is improved by more than 50%, and oil consumption and emission are reduced.

本发明涉及一种燃油发动机及其驱动装置和工作方法。  The invention relates to a fuel engine, a driving device thereof and a working method.
背景技术Background technique
现有传统的汽油发动机,一般采用二冲程或者四冲程式,其燃油功效只有30%左右,其余损耗于冷却液(约占30%)和排入大气中(约占30%-40%)。而需要提高发动机的燃油功效,就必须充分利用发动机做功后剩余的燃气。而现有的汽油发动机虽然设有主副缸,但是主副缸均设有喷油嘴和火花塞,也即主缸和副缸均采用混合气燃烧进行做功,其剩余燃气直接排出,油耗大。所以,有必要对现有的汽油发动机进行改进。The existing conventional gasoline engine generally adopts two-stroke or four-stroke type, and its fuel efficiency is only about 30%, and the rest is lost to the coolant (about 30%) and discharged into the atmosphere (about 30%-40%). In order to improve the fuel efficiency of the engine, it is necessary to make full use of the remaining gas after the engine is working. While the existing gasoline engine is provided with a main and auxiliary cylinder, the main and auxiliary cylinders are provided with a fuel injector and a spark plug, that is, both the master cylinder and the secondary cylinder are operated by a mixed gas combustion, and the remaining gas is directly discharged, and the fuel consumption is large. Therefore, it is necessary to improve the existing gasoline engine.

    步骤40,主缸从做功冲程进入停顿冲程,双向阀打开,第一活塞停在主缸的下止点处,第一传动件也停止活动,与此同时,副缸从压缩冲程进入做功冲程,混合燃气燃烧后的剩余燃气通过双向阀进入副缸体内以带动第二活塞从副缸的上止点运动至下止点以使副缸做功,且第二活塞带动第二传动件活动以使主轴转动;In step 40, the master cylinder enters the pause stroke from the power stroke, the two-way valve opens, the first piston stops at the bottom dead center of the master cylinder, and the first transmission member also stops moving. At the same time, the secondary cylinder enters the power stroke from the compression stroke. The remaining gas after the combustion of the mixed gas enters the auxiliary cylinder through the two-way valve to drive the second piston to move from the top dead center of the secondary cylinder to the bottom dead center to make the secondary cylinder work, and the second piston drives the second transmission member to move Spindle rotation;
    步骤50,主缸从停顿冲程进入排气冲程,双向阀关闭,第一活塞从主缸的下止点运动至上止点以将主缸体内的剩余燃气通过第一排气口排出,且第一活塞带动第一传动件活动以使主轴转动,与此同时,副缸从做功冲程进入停顿冲程,第二活塞停在副缸的下止点处,第二传动件也停止活动;Step 50, the master cylinder enters the exhaust stroke from the pause stroke, the two-way valve is closed, and the first piston moves from the bottom dead center of the master cylinder to the top dead center to discharge the remaining gas in the master cylinder through the first exhaust port, and the first a piston drives the first transmission member to move to rotate the main shaft. At the same time, the auxiliary cylinder enters the suspension stroke from the power stroke, the second piston stops at the bottom dead center of the auxiliary cylinder, and the second transmission member also stops moving;
    步骤60,主缸从排气冲程进入进气冲程,重复上述步骤。In step 60, the master cylinder enters the intake stroke from the exhaust stroke, and the above steps are repeated.
