Volume 37 Chapter 12 Iron Dragon Iron (1)

Dual drive engine?

If the person who said this sentence was an engineer, the people in the room would not be surprised, but the person who said this sentence was Master Zhulong, then...

Look at Zhang Tie's iron tower-like body at the moment, the whole person is like a violent machine from ancient times, and look at his murderous bald head who almost wrote the words "I am the boss" on his head. The five of them opened their mouths wide open one by one.

"This... this is... the real person... you invented it yourself?"

The oldest-looking old man in the room stared at Zhang Tie in astonishment, and asked in amazement.

"Why, don't I look like an educated person? A knight should have a simple mind and well-developed limbs?" Zhang Tie looked at him, his eyes widened, and the old man suddenly felt a mountain-like pressure rushing towards his face, almost frightened. Urine.

"No...no...I mean...mean...real people..."

When the old man was nervous, his tongue became knotted. The more nervous he was, the more he could not speak smoothly. beads of sweat.

"Please don't blame the real person. I think what Patriarch Yan means is that the people who can invent and design this kind of machine are definitely top experts in this field. There are such knights in Taixia, but no one has seen them before. , and because of this, after seeing the blueprints produced by the real person, everyone was both admiring and shocked, but they didn’t expect the real person to be an all-rounder, even proficient in mechanical design, it’s really amazing!"

At this time, it was Sun Qiming who spoke for the old man.

Hearing that Sun Qiming spoke up for himself at this time, the old man who was extremely jealous of Sun Qiming just now gave Sun Qiming a grateful look, wiped the cold sweat from his forehead, and nodded quickly, "Yes, yes, that's what I mean, that's what I mean. This means, the ability of a real person... is really admirable!"

The few people in the room are actually in some kind of competitive relationship after entering the room, but even so, Sun Qiming is still willing to speak out to help others when they are in trouble. From this point, it can be seen that Sun Qiming Zhang Tie's kind heart and generosity made Zhang Tie look at Gao Sun Qiming again in his heart, and felt that the man his junior sister Lu Shasha had found was reliable and a good match.

"Well, it's good if it doesn't mean that!" Zhang Tie nodded and glanced at Sun Qiming, "Before I became a knight, I was very interested in the power system, and after I became a knight, because of my strong mental power , I can almost remember ten lines at a glance when reading a book, and after learning a lot of experience and knowledge from the predecessors, I even have a great breakthrough in this aspect..."

In fact, because of the knight's long lifespan and strong spiritual power, in Taixia, no matter in any aspect, even those fields that are not related to combat, such as music, art, painting, etc., the knights are the ones who stand at the pinnacle of these fields , it's just that these knights don't make a name for it.

It is really nothing new for a knight to show extremely high attainments in the field of mechanical manufacturing. If a knight is really interested in this, if he can persist for a hundred years, he will become a top expert no matter what. But none of the people present could guess Zhang Tie's real age.

Of course, the thing invented by Zhang Tie was really amazing to the few people present.

"I'm so blunt, I still ask a real person to unravel the mystery of this machine for me..." Sun Qiming bowed to Zhang Tie to the ground.

"Forget it, then I'll tell you what's so strange about this machine!" Zhang Tie said, his face became serious, and he began to point to the drawings and start explaining to these people.

This dual-drive engine is very important to Zhang Tie, and the few people present were selected by Zhang Tie to manufacture this kind of machine. There will be problems later,

Therefore, it is absolutely necessary to popularize science for these people, first let them understand what is going on with this machine.

"Someone said just now that this machine is like an internal combustion engine and an external combustion engine. This sentence is true. This machine is indeed both an internal combustion engine and an external combustion engine, because this machine is at the same time It has the design essence of external combustion engine and internal combustion engine!" Zhang Tie pointed to the cylinder on the design drawing, "This design essence is here, in the cylinder part of this machine..."

"The traditional internal combustion engine before the cataclysm, because it generates a lot of heat during combustion, the entire engine will be at extremely high temperature during operation. When the temperature of the engine is high, it will even affect the operation of the engine, so , The engines before the catastrophe had to be equipped with various water-cooling or air-cooling systems to cool the engine, allowing the engine to cool down while working. Many internal combustion engines before the catastrophe only need to be ignited and run for a few minutes. The temperature of the water will rise rapidly, even boiling, for people before the cataclysm, this is a normal thing!"

"According to some documents I have seen about engines before the catastrophe, at a certain time before the catastrophe, drivers who drove some small-power tractors with only a technician's horsepower at that time, as long as they drove the tractor, they would be around. I will carry three things with me at any time, these three things, one is the crank handle of the engine, which is used to start the tractor, and the other is the large water tank on the car, which is used to add water to the water cooling system of the tractor at any time, so as not to cool down in time Burning out the engine, the third is eggs, as long as those drivers are hungry, throw eggs into the water-cooling system, and they will be cooked immediately, and the water-cooling system is like boiling water at any time..."

"For people of our time, when steam and heat have become our main sources of power, it is a joke and a huge waste to equip the engine with a cooling system to cool down. In this huge waste, take the ordinary gasoline engine before the cataclysm as an example. At that time, the power used for power output of most gasoline engines generally only accounted for 20% to 100% of the total heat of fuel combustion. Thirty percent, the diesel engine is higher, which can reach about 30% to 45%. For an ordinary gasoline engine, the heat dissipated and discharged from the engine in the form of waste heat accounts for the total heat of combustion in the cylinder. Seventy to eighty percent, 20 to 30 percent of the heat is used, and 70 to 80 percent is wasted, and a cooling system is specially developed for the wasted heat. This is not a joke that puts the cart before the horse. What is it? Most of the internal combustion engines before the catastrophe, from the beginning of the design, there is a huge waste of fuel combustion heat and the defect of dissipation, the traditional internal combustion engine cannot maximize the use of the energy of fuel combustion..."

"The dual-drive engine I invented can make up for this shortcoming of the traditional internal combustion engine to the greatest extent, and at the same time best combine the water cooling system of the traditional internal combustion engine with the steam power system we use now. The key point of this combination lies in the traditional internal combustion engine. The cylinder part of the..."

"...when fuel is mixed with air and burned in the cylinder, the reciprocating piston in the cylinder starts to move, pushing the crank connecting rod mechanism to start stroke movement. From this point of view, it is an internal combustion engine, and at the same time , You see, the cylinder of this machine is also different from the cylinder of the ordinary reciprocating piston engine before the cataclysm. The difference is that the power brought by the expansion of the fuel in the cylinder is exactly the same Less is transferred to the piston in the cylinder, which pushes the piston and the crank connecting rod mechanism to perform mechanical movement, and when the fuel burns in the cylinder, in addition to expanding, more heat it brings during combustion will pass through the cylinder wall, The steam water cooling layer on the periphery of the cylinder wall is heated, and from the latter, the combustion of the cylinder becomes the power source of the heating of the external combustion engine..."

"The core of this dual-drive engine is the cylinder. Compared with the cylinder of the traditional internal combustion engine, it has several significant differences. These differences are mainly manifested in four aspects. Among these four aspects, one is the layout of the cylinder, and the other is The choice of material for the cylinder block, the third is the cooling system of the cylinder, and the fourth is the design of the empty layer on the outer wall of the cylinder..."

As soon as Zhang Tie mentioned this, he entered into the role, and what he said was very professional. For a while, several audience members even forgot Zhang Tie's identity as an earth knight, and began to concentrate on listening to Zhang Tie's introduction , Gradually attracted all the attention by Zhang Tie's introduction.

...

"...Different from the cylinder block material of ordinary internal combustion engines, the cylinder material of this engine must have extremely high Therefore, according to Fourier’s metal heat conduction law, the best material for this cylinder block is super-dense double-hard three-pole aluminum alloy. This aluminum alloy should also complete a four-phase hot-dip spraying on the water-cooling layer. , this process is consistent with the hot-dip process of the water-cooling layer of the internal combustion engine used by many high-end sedans in the Sea Dragon..."

"Because the exhaust pipe of the internal combustion engine also takes away a lot of heat, the layout of the exhaust pipe of this engine is a bit special. The high-heat engine exhaust gas in the exhaust pipe can be used to complete the secondary heating of the steam in the steam power system..."

"So, the combustion of this engine's fuel in the cylinder is equivalent to pushing the two power systems of the piston in the cylinder and the steam power outside the cylinder to work at the same time. The work efficiency it brings is also unparalleled. Its cylinder The displacement is 18.5 liters, combined, its cylinder power density is... its cylinder compression ratio is..."

"The internal combustion engine part of this engine, through the efficiency enhancement of the two-stage turbocharging device, its single output power can reach 940 horsepower, while the steam power part driven by the external combustion engine can bring a separate output power of 610 horsepower. Horsepower, these two sets of different output power can be used independently, one as a power drive system, and the other is connected to the steam weapon module, or a differential transfer gearbox can be used to unify the power of the two into one output direction , in different situations and time periods to maximize the output of a certain aspect, and in the case of not connecting the steam weapon module, because some metallurgical materials brought by this era exceed the level of metal smelting and processing before the cataclysm Beyond, the weight of the entire engine can be controlled within 800 kg..."

Because this engine embodies a dream that Zhang Tie once had, Zhang Tie explained it very carefully, and it can even be called meticulous.

While explaining this engine, Zhang Tie's body was here, but his heart had already flown to the Cernes war zone, which was filled with gunpowder and blood everywhere...

The former Celnes war zone left too many memories of Zhang Tie and shed too much blood on him.

This engine is the first engine specially designed by Zhang Tie for human beings in the black iron era...

At this time, while explaining the design principle of this engine, Zhang Tie couldn't help but have a hypothesis in his heart-if there was such an engine in the Cernes theater, there would be such an engine. Propeller planes, so what would have been the outcome of the Battle of Cernes? Would the airship unit in the Cernes theater have a better ending?

The answer is unquestionable. If such an engine existed at the beginning, and aircraft could be manufactured with such an engine, then the results of the entire Cernes theater would definitely have to be rewritten. In the end, the demons may still be able to break through the defense line of the human race in Cernes, but the price paid by the demons will definitely be many times higher. The human race may still have to complete a strategic retreat from the Cernes theater in the end, but many of them should not be lost. The blood that should not be made, the sacrifice that should not be made, and the tragedy that should not have happened should all be avoided.

The honor of the Eagle of Cernes that I had won in the Cernes Theater was not so much an honor as it was the most authentic example of the tragic departure of the Terran Allied Forces, especially the Human Airship Troops, in the Cernes Theater portrayal.

Killing a few Demon Winged Demons in the air by one person can actually alarm the headquarters of the Human Race Alliance Army in a subcontinent. On the front line, he won a title of great prestige and honor among the Human Race Alliance Army. Sarcasm and helplessness.

The reason for this situation is that in the Cernes theater at that time, if you don’t look at the contest between the knights of the two sides in the air, the demons in the Cernes theater have almost tortured the airships and air units of the human race to the ground. , Many times, the airship troops of the human race and those brave glider pilots encounter the wing demons of the demon race, and what they wait for is a completely one-sided massacre...

At that time in the Cernes theater, if one of the bravest, most casualty, and most respected arms was to be selected, and glider pilots ranked first, absolutely no one would be dissatisfied.

Zhang Tie, who was the only air cavalry in the entire Saernes theater at that time, knew very well that the sky of a million square kilometers in the entire Saernes theater was almost covered with the blood of countless human glider pilots who went on and on.

The Battle of Cernes was a tragic song sung by human glider pilots and airship soldiers in the Hawaiian subcontinent with countless lives and blood... R1152
