Dual drive engine
If the person who said this was an engineer, then several people in the room would not be surprised, but the person who said this was Zhulong Zhenren, so...
Look at Zhang Tie's iron tower-like figure at this moment. The whole person is like a violent machine from ancient times. Look at his murderous bald head that almost has the words "I am the boss" written on his head. There are so many people in the room. Each of the five people opened their mouths.
"This... this is... a real person... invented by yourself?"
An old man who seemed to be the oldest in the room looked at Zhang Tie dumbfounded and asked in shock.
"Why, don't I look like a cultured 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... I mean... real person..."
The old man was so nervous that his tongue became knotted. The more nervous he was, the more clumsy he became when speaking. beads of sweat.
"Please don't blame the real person. I think what Patriarch Yan means is that those 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 ever seen them. , and therefore, after seeing the drawings that the real person produced, everyone was impressed and shocked at the same time. Unexpectedly, the real person is also a versatile man in both civil and military affairs, and is even proficient in mechanical design, which is really amazing!"
At this time, it was Sun Qiming who helped the old man speak.
Hearing Sun Qiming speak up for him at this time, the old man who was extremely jealous of Sun Qiming just looked at Sun Qiming gratefully, and while wiping the cold sweat on his forehead, he nodded quickly, "Yes, yes, that's what I mean, that's it." This means that the real person’s ability... is really admirable!”
The people in the room were actually in a certain competitive relationship after entering the room, and even so, Sun Qiming was still willing to lend a helping hand when others were in trouble. From this, it can be seen that Sun Qiming He was kind-hearted and tolerant, which made Zhang Tie take another look at Gao Sun Qiming in his heart and felt that the man his junior sister Lu Shasha had found was quite reliable and a good match.
"Well, that's not what I meant!" Zhang Tie nodded and glanced at Sun Qiming, "Before I advanced to become a knight, I was very interested in the power system. After I advanced to become a knight, because of my strong mental power , I can never forget almost every line I read. After learning the experience and knowledge of many predecessors, I have also made great breakthroughs in this area... "
In fact, because of the long lifespan and strong mental power of knights, in Taixia, no matter what, even those fields not related to combat, such as music, art, painting, etc., those who stand at the top of these fields are knights. , it’s just that these knights are not famous for it.
It is nothing new for a knight to show extremely high attainments in the field of mechanical manufacturing. If a knight is really interested in this and can persist for a hundred years, he will become a top expert no matter what. No one present could guess Zhang Tie's true age.
Of course, what Zhang Tie invented was really astonishing to a few people present.
"We are stupid, please ask a real person to unlock the secret of this machine for us..." Sun Qiming bowed to the ground in front of Zhang Tie.
"Forget it, then I'll tell you what's so strange about this machine!" Zhang Tie said, his face became serious, and he started pointing at the drawings and started explaining to these people.
This dual-drive engine is very important to Zhang Tie, and these people present were selected by Zhang Tie to build this machine. If even they cannot figure out the design ideas and some key technical principles of this machine, it is inevitable that they will There will be problems later, and therefore, it is absolutely necessary to educate these people on science and let them understand what is going on with this machine.
"Someone just said that this machine is like an internal combustion engine and an external combustion engine. This is right. This machine is indeed both an internal combustion engine and an external combustion engine, because this machine is both an internal combustion engine and an external combustion engine. We have the design essence of external combustion engines and internal combustion engines!" Zhang Tie pointed to the cylinder on the design drawing, "The essence of this design is here, in the cylinder part of this machine..."
"The traditional internal combustion engines before the Catastrophe generated a lot of heat during combustion, and the entire engine would be at an extremely high temperature during operation. When the engine temperature was high, it would even affect the operation of the engine, so , engines before the Cataclysm had to be equipped with various water-cooling or air-cooling systems to cool the engine while the engine was working. Many internal combustion engines before the Cataclysm only needed to be ignited and run for a few minutes before cooling the engine in the water tank. The temperature of the water will rise rapidly and even boil. For people before the catastrophe, this is a normal thing!"
"In some literature records I have seen about engines before the Cataclysm, at a certain time before the Catastrophe, the drivers at that time were driving some low-power tractors with only technician horsepower. As soon as they drove the tractor, they were surrounded by people. I carry three things with me at any time. Of these three things, one is the starting crank of the engine, which is used to start the tractor. The second is the large water tank that is always available on the vehicle, which is used to add water to the water-cooling system of the tractor at any time to prevent the cooling from being delayed in time. Burning out the engine, the third is the eggs. When those drivers are hungry, they throw the eggs into the water-cooling system and they will be cooked all of a sudden. The water-cooling system is like boiling water at any time... "
"For people of our time, when steam and heat have become our main source of power, this kind of move to equip the engine with a cooling system is a joke and a huge waste. Among this huge waste, take the ordinary gasoline engines before the Catastrophe as an example. At that time, the power used for power output of most gasoline engines generally only accounted for 20 to 100 percent of the total heat of fuel combustion. Thirty, the diesel engine is higher, 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 combustion heat in the cylinder. Seventy to eighty percent, the heat used is 20 to 30%, and 70 to 80% is wasted. A cooling system must be developed specifically for the wasted heat. Isn't this a joke that puts the cart before the horse? The vast majority of internal combustion engines before the catastrophe had huge waste and dissipation defects of fuel combustion heat from the beginning of their design. Traditional internal combustion engines cannot maximize the utilization of fuel combustion energy... "
"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 are currently using. The key point of this combination is the traditional internal combustion engine. The cylinder part..."
“… When fuel is mixed with air and burned in the cylinder, the reciprocating piston in the cylinder begins to move, pushing the crank connecting rod mechanism to start the stroke movement. From this perspective, 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. This difference is that while the fuel in the cylinder is burning, its expansion brings about more power. is transferred to the piston in the cylinder, pushing the piston and crank connecting rod mechanism to perform mechanical movement. When the fuel burns in the cylinder, in addition to expanding, the more heat it brings when burning will pass through the cylinder wall, causing The steam-water cooling layer on the periphery of the cylinder wall is heated. From the latter point of view, the combustion of the cylinder becomes the source of heating power for the external combustion engine... "
"The core of this dual-drive engine is the cylinder. Compared with the cylinders of traditional internal combustion engines, it has several significant differences. These differences are mainly reflected in four aspects. One is the layout of the cylinder, and the other is the cylinder layout. The first is the choice of cylinder body material, the third is the cooling system of the cylinder, and the fourth is the design of the air layer on the outer wall of the cylinder... "
As soon as Zhang Tie talked about this, he got into the role, and what he said was very professional. For a while, several listeners even forgot about Zhang Tie's identity as an earth knight and began to listen to Zhang Tie's introduction attentively. , gradually attracted all the attention by Zhang Tie's introduction.
…
"... Different from the cylinder material of ordinary internal combustion engines, the cylinder material of this engine must have extremely high wear resistance and hardness in order to smoothly transfer heat energy from the combustion chamber to the water-cooling layer next to it. Thermal conductivity, therefore, according to Fourier's law of metal thermal conductivity, the best material for this cylinder block is calculated as ultra-dense double-hard triple-pole aluminum alloy. This aluminum alloy should also complete a four-phase hot-dip spraying in the water-cooling layer. This process is consistent with the hot-dip process of the water-cooling layer of the internal combustion engine used in many high-end sedans..."
“Because the exhaust pipe of an internal combustion engine also takes away a lot of heat, the layout of the exhaust pipe of this engine is somewhat special, using a surround and in-line design idea. In this way, after the engine is started, The high-heat engine exhaust gas in the exhaust pipe can be used to reheat the steam in the steam power system... "
"So, the combustion of fuel in this engine's cylinder is equivalent to simultaneously pushing the piston in the cylinder and the steam power outside the cylinder to work. The work efficiency it brings is also unparalleled. Its cylinder The displacement is 18.5 liters. Taken together, 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 turbocharger device, can achieve a separate output of 940 horsepower, while the steam power part driven by the external combustion engine has a separate output of 610 Horsepower, these two different sets of output power can be used independently. One is used as a power drive system, and the other is connected to the steam weapon module. A differential transfer gearbox can also be used to unify the power of the two into one output direction. , to maximize the output of a certain aspect in different situations and time periods, without connecting the steam weapon module, because this era has brought about certain metallurgical materials that exceed the level of metal smelting and processing before the cataclysm. Beyond that, the weight of the entire engine can be controlled within 800 kilograms... "
Because this engine embodies a dream that Zhang Tie once had, Zhang Tie explained it very attentively, even in detail.
While explaining this engine, Zhang Tie's body was here, but his heart had already flown to the Cernes war zone, which was once filled with smoke and blood...
The former Sernes war zone left Zhang Tie with too many memories and shed too much blood on him.
This engine is the first engine specially designed for propeller aircraft in the black iron era specially designed by Zhang Tie...
At this time, while explaining the design principles of this engine, Zhang Tie couldn't help but have a hypothesis in his mind. If there had been such an engine in the Sernes war zone, there would have been such an engine-driven propeller aircraft. , then, what will be the outcome of the Battle of Cernes? Could things have ended better for the airship troops in Sernes Theater
The answer is unquestionable. If such an engine had existed at the beginning and an aircraft could have been manufactured with such an engine, then the outcome of the entire Cernes Theater would have definitely been rewritten. The Demons may still be able to break through the human defense line in Cerness in the end, but the price paid by the Demons will definitely be many times higher. The Humans may still have to complete a strategic retreat from the Cernes war zone in the end, but many of them should not be lost. The blood, the sacrifices that should not have been made, the tragedies that should not have happened, should be able to be avoided.
The honor of the Eagle of Cernes that I had received in the Cernes War Zone was not so much an honor as it was the most real reminder of the tragic departure of the human coalition forces, especially the human airship troops, from the Sernes War Zone. Portrait.
One person killed several demon winged demons in the air, and was able to alert the headquarters of the human coalition forces in a subcontinent. On the front line, he received a title of great prestige and honor among the human coalition forces. This in itself has some Ironic and helpless.
The reason for this situation is that in the Cernes war zone at that time, if we did not look at the competition between the knight-level forces of the two sides in the air, the demons had almost completely beaten the human airships and aerial troops in the Cernes war zone. , many times, when the human airship troops and those brave glider pilots encounter the demon wing demons, what awaits them is a one-sided massacre...
At that time, in the Sernes war zone, if one wanted to choose the bravest, highest casualty rate, and most respected branch of the military, glider pilots would be ranked first, and absolutely no one would be dissatisfied.
Zhang Tie, who was the only air cavalryman in the entire Sarnes war zone at that time, knew very well that the sky covering millions of square kilometers in the entire Sarnes war zone was almost everywhere covered with the blood of countless human glider pilots who came one after another.
The Battle of Cernes was a tragic song played by human glider pilots and airship troopers on the Hawaiian subcontinent with countless lives and blood...
