    When many people talk about the power data of the engine, they will talk about how many horsepower it has.  But few people will mention how much torque is.  In fact, the former is an outsider, while the latter is an insider.  The horsepower of the engine is only obtained at the maximum speed.  Ordinary people seldom step on the accelerator to the bottom, so the maximum horsepower is not available.  But the torque is very useful, because it intuitively reflects the magnitude of the traction torque. In layman's terms, it is whether there is strength.

    Although the single-cylinder diesel engine does not have a lot of horsepower, its torque is quite powerful.  At this time, when Qin Baoshan mentioned these factors, Ma Sanbao finally spoke.

    "What Director Qin said is correct. Due to the very high compression ratio of the diesel engine, its torque will be very large, but at the same time, because it is compression-ignited, the noise of this kind of engine will be relatively loud. In this era, large  Some engine designers will choose gasoline as power. Diesel is an inferior fuel, but if diesel engines are really made, it may be more suitable for tanks. We have learned that the Soviets were in  Using a diesel engine as the power of the tank gives their tank a strong performance. Moreover, the fuel consumption of this engine is relatively low, so the stroke of the tank is relatively strong. If Director Qin proposed to manufacture a single-cylinder diesel engine, it should be  Considering the current industrial base of the Eighth Route Army. However, if it is a single cylinder, then the vibration of this engine will be relatively strong and the noise will be relatively loud.¡±

    Qin Baoshan was very surprised by what Ma Sanbao said.  He is not only a technician, but has also risen to the level of a designer, and even has a strong predictive ability. Although he has never seen this kind of cake engine, he can also predict the actual performance of this engine.  working status.

    Indeed, the noise of this kind of engine working is so loud that people can hear it from a long distance.  From the chugs of black smoke coming out of the exhaust pipe, you can tell that this kind of thing has appeared two miles away.  But for the Eighth Route Army, these are not a problem.  It is not the study of high-end cars, but the comfort level of the occupants needs to be taken into consideration. Now we have to solve the problem of availability first.

    "I have some ideas about this single-cylinder engine. Now I will draw a simple design drawing. But there may be some problems. I hope you can refine this design drawing."

    Qin Baoshan designed the general structure of this engine according to his memory in the previous era.  It's in my head, right now, just to draw it.

    In this era, engines usually have cylinders placed vertically.  But this single-cylinder engine has horizontal cylinders.  The purpose of placing the cylinder vertically is to allow the piston to move up and down when it is in motion, thus avoiding the phenomenon of eccentric wear caused by the weight of the piston itself.  Now, if the cylinder is to be set horizontally, then under the influence of the weight of the piston, the lower half of the piston ring will wear more than the upper half.  But to them, it doesn't matter.  As long as it can be used, as long as the structure is simple.

    The valve is at the top, connected to the lower camshaft by two rocker arms.  If the manufacturing technology is not up to standard, the two rocker arms may break.  In Qin Baoshan's original era, there were often rural repairers who would remove the two rocker arms and replace them.  In their mouths, these two things are called chopsticks, and Qin Baoshan has seen them before.

    The fuel injector is placed obliquely on the top of the cylinder, and then connected to a high-pressure oil pump below through a high-pressure oil pipe.  The structure of the whole machine is very simple, even the water tank is evaporative.  When using, pour water into it.  The water will boil, and then it will continue to run without any management. When the water is almost boiled, add some water to it, it's that simple.  This can save the complicated water circulation system.  On one side of the engine is the starter crank, and on the other side is a huge flywheel.  This is one of the reasons why this single-cylinder engine has a large torque.

    If it is a four-cylinder engine, one cylinder will work at every moment.  In this way, the engine can run continuously and stably.  All it takes is a tiny flywheel.  But this single-cylinder engine has only one cylinder.  In the process of the piston reciprocating twice to complete a cycle, there is only one process of doing work. At other times, it is necessary to rely on the inertia of the flywheel to drive the machine to complete, so this also requires a large-mass flywheel.  Enough energy to drive the machine to complete several other processes.

    For the sake of simplicity, Qin Baoshan does not intend to use any other means of activation.  Directly use the crank, through a reasonable placement, you can put the crank in the position of the gunner in the car.  This way, the start-up process can also be done internally should the engine stall midway.

    Now Qin Baoshan is talking on the spot while drawing on the blueprint.  Finally, the model of this engine is almost drawn.  Definitely the exact size?It needs all technicians to make precise decisions, but the general principle is like this.

    Qin Baoshan doesn't know when this kind of agricultural engine of later generations appeared, but it definitely doesn't exist now.  So this is also one of his innovations.  After he finished speaking, the scene fell into a moment of silence.

    After that, Ma Sanbao looked at Qin Baoshan with complicated eyes: "Director Qin, you are really amazing, there is nothing you can't do. According to your design, the engine uses the least parts, and at the same time realizes  Basic functions. As for how much power it can generate, it depends on the size of the engine. However, I can be sure that it will definitely work."

    When this single-cylinder engine first came out, it was only a six-horsepower or eight-horsepower product.  But later it was widely recognized in the society, so this kind of engine factory made persistent efforts to continuously improve the power of the engine.  If the tenth level of horsepower is not enough, then more than 20 horsepower, and if more than 20 horsepower is not enough, then thirty horsepower, forty horsepower.  Just simply zoom in.  But the bigger the thing, the stronger the vibration and the louder the noise, so there are limitations.

    As a technician from Detroit, Ma Sanbao also has deep research experience in engines.  Now he can know with these experiences that this will be the engine with the simplest structure, strong power, and extremely loud noise and vibration in history.  He hardly dared to imagine what kind of effect it would be if this engine was put on a tank?

    The engine problem was solved like this.  Qin Baoshan proposed a general research direction, and everyone refined according to Qin Baoshan's design, and then manufactured a prototype.  This is not the first time, Qin Baoshan has done this before, so it will definitely be done.

    But a simple engine is not enough.  (Remember the site URL: www.hlnovel.com
