Dual-drive engine The person who said this, if it was an engineer, a few people in the room would not be surprised, but the person who said this sentence was a real person with a candle dragon, then Look at Zhang Tie's tower-like body shape at the moment, the whole person is like a violent machine from ancient times, and then look at his murderous bald head that almost wrote the words "I am the boss" on his head, and the five people in the room opened their mouths one by one.
"This is a real person, you invented it yourself" The oldest old man in the room looked at Zhang Tie dumbfounded and asked in surprise.
"Why, don't I look like a literate person, a knight should be simple-minded and well-developed" Zhang Tie looked at him, his eyes widened, and the old man suddenly felt a mountain-like pressure rushing over his face, almost scared to pee.
"No, no, I mean real people" The old man was nervous, his tongue was knotted, the more nervous he was, the more unfavorable he was to speak, the more unfavorable he was to speak, and the more nervous he became, in just a few seconds, the old man's forehead was already covered with a bead of sweat the size of a soybean.
"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 the top experts in this area, Taixia has such a knight, but everyone has never seen it, and therefore, after seeing the drawings taken out by the real person, everyone is both admired and shocked, I didn't expect that the real person is still a civil and military all-rounder, and even proficient in mechanical design, which is really breathtaking" At this time, it was Sun Qiming who helped the old man speak.
Hearing that Sun Qiming opened his mouth for himself at this time, the old man who was still jealous of Sun Qiming just now glanced at Sun Qiming gratefully, and while wiping the cold sweat on his forehead, he nodded hurriedly, "Yes, yes, that's what I mean, that's what I mean, the fact that a real person is too admirable."
These people in the house are actually in some kind of competition after entering the house, and even so, Sun Qiming is still willing to speak up when others are in difficulty, from this point, it can be seen that Sun Qiming is kind-hearted and tolerant, which makes Zhang Tie look at Gao Sun Qiming again in his heart, and feels that the man he is looking for by his little sister Lu Shasha is quite reliable and a good match.
"Well, that's not what it means" Zhang Tie nodded and glanced at Sun Qiming, "Before I advanced knight, I was very interested in the power system, and after the advanced knight, because of my strong spiritual power, I almost never forgot to read a book, and after learning a lot of experience and knowledge from my predecessors, I also made a great breakthrough in this ability."
In fact, because of the knight's long life and strong mental power, in Taixia, no matter what aspect, even those fields that are not related to combat, such as music, art, painting, etc., those who stand at the pinnacle of these fields are knights, but these knights are not famous for this.
It is really nothing new for a knight to show extremely high attainments in the field of mechanical manufacturing, and if a knight is really interested in this, he can persist for a hundred years, and he will become a top expert no matter what.
None of the people present could guess Zhang Tie's true age.
Of course, this thing invented by Zhang Tie was a little too amazing for the few people present.
"I'm waiting for me to be reckless, and I ask a real person to solve the mystery of this machine for us," Sun Qiming shook Zhang Tie to the ground.
"Well, 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 began to explain to these people.
This dual-drive engine is very important to Zhang Tie, and these people present are all selected by Zhang Tie to manufacture this kind of machine, if even they can't figure out the design ideas and some key technical principles of this machine, it is inevitable that there will be problems later, and therefore, it is absolutely necessary to give these people a popular science, let them understand what this machine is going on.
"Someone just said that this machine is like an internal combustion engine, and it is like an external combustion engine, this sentence is good, this machine is indeed both an internal combustion engine and an external combustion engine, because this machine has the design essence of both external combustion engine and internal combustion engine" 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 engine before the cataclysm, because of a large amount of heat during combustion, the entire engine will be at a very high temperature during operation, when the temperature of the engine is high, it will even affect the operation of the engine, therefore, the engine before the cataclysm has to be equipped with a variety of water cooling or air cooling systems to cool down the engine, so that the engine can be cooled down while working, many internal combustion engines before the cataclysm, as long as the ignition runs for a few minutes, The temperature of the water in the tank, which cools the engine, rises rapidly, and even boils, which is normal for people before the cataclysm."
"In some of the literature I saw about the engine before the cataclysm, in a certain time before the cataclysm, at that time, the driver of the low-power tractor who only had the horsepower of the technician, as long as he drove the tractor, he would carry three things around him at any time, these three things, one is the starting crank of the engine, which is used to drive the tractor, the second is the large water tank that is always on the car, which is used to add water to the water cooling system of the tractor at any time, so as not to burn the engine if the cooling is not done in time, and the third is the egg.
When those drivers are hungry, they throw their eggs into the water cooling system, and they are cooked in an instant, and the water cooling system is quite like boiling water at any time."
"And for the people of our time, when steam and heat have become our main sources of power, this kind of initiative to equip the engine with a cooling system to cool down is a joke, but also a huge waste, in this huge waste, take the ordinary gasoline engine before the cataclysm as an example, at that time, the vast majority of gasoline engines, the power used for power output generally only accounts for 20 to 30 percent of the total heat of fuel combustion, diesel engines are higher, It can reach about 30 to 45 percent, an ordinary gasoline engine, in the form of waste heat dissipation and exhaust of the engine's heat accounts for 70 to 80 percent of the total heat burned in the cylinder, the use of heat is 20 percent, waste of 780 percent, but also for the waste of heat to develop a cooling system, this is not the cart before the cart What is the joke, the vast majority of internal combustion engines before the cataclysm, from the beginning of the design, there is a huge waste of fuel combustion heat and scattered defects, Conventional internal combustion engines cannot maximize the use of fuel combustion energy."
"The dual-wheel drive engine I invented can make up for the shortcomings of the traditional internal combustion engine to the greatest extent, and at the same time combine the water cooling system of the traditional internal combustion engine with the steam power system we use now.
"When the fuel is mixed with air and burned in the cylinder, the reciprocating piston in the cylinder begins to move, pushing the crank linkage mechanism to start the 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, this difference is that the fuel in the cylinder is burning at the same time, and the power brought by its expansion is transmitted to the piston in the cylinder.
The piston and crank linkage are pushed to move mechanically, and when the fuel is burned in the cylinder, in addition to expanding, the more heat it brings when it burns will pass through the cylinder wall to heat the steam-water cooling layer on the periphery of the cylinder wall, and from the latter, the combustion of the cylinder becomes the power source for 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, mainly in four aspects, these four aspects, one is the layout of the cylinder, the second is the choice of cylinder block material, the third is the cooling system of the cylinder, and the fourth is the empty layer design of the outer wall of the cylinder" As soon as Zhang Tie talked about this, he entered the role, and he spoke very professionally, and for a while, several listeners even forgot the identity of Zhang Tie's earth knight, and began to listen attentively to Zhang Tie's introduction, and gradually attracted all the attention of Zhang Tie's introduction.
"Different from the cylinder block material of the ordinary internal combustion engine, the cylinder material of this engine ensures the wear resistance and hardness at the same time, in order to smoothly transfer the heat energy from the combustion chamber to the water-cooled layer next to it, it must also have extremely high thermal conductivity.
The hot-plating process of the water-cooled layer of the internal combustion engine used in many high-end cars in Fairy Dragon is the same."
"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, using the design idea of surround and inline, so that after the engine is started, 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."
"Therefore, the combustion of fuel in the cylinder of this engine is equivalent to pushing the piston in the cylinder and the steam power system outside the cylinder at the same time, the work efficiency it brings, is also unparalleled, its cylinder displacement is 185 liters, combined, its cylinder power density is its cylinder compression ratio of " "The internal combustion engine part of this engine, after the efficiency of the two-stage turbocharging device, its separate output power can reach 940 horsepower, and the steam power part driven by the external combustion engine, it brings a separate output power of 610 horsepower, these two different sets of output power, can be used as a separate power, one as a power drive system, one 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, Maximize the output of certain aspects in different situations and time periods, and without connecting the steam weapon module, because of the metallurgical materials brought by this era to exceed the level of metal smelting and processing before the cataclysm, the weight of the entire engine can be controlled within 800 kilograms" Because this engine embodies a dream of Zhang Tie, Zhang Tie explained it very carefully, and it can even be called meticulous.
When explaining this engine, Zhang Tie's body was here, and his heart had already flown to the Cernes war zone that was once filled with gunpowder and blood The former Selness war zone left too many memories of Zhang Tie and threw too much of his blood.
This engine is the first engine specially designed by Zhang Tie for propeller aircraft in the Black Iron Era At this time, while expounding the design principle of this engine, Zhang Tie couldn't help but have an assumption in his heart that if there was such an engine and a propeller aircraft driven by such an engine in the Cernes Theater of Operations, then what would be the result of the Battle of Cernes, and whether the outcome of the airship troops in the Cernes Theater would be a little better The answer is undoubted, if at the beginning, there was such an engine, and an aircraft could be made from such an engine, then the results of the entire Cernes theater of operations must definitely be rewritten.
The demons may still be able to break through the Terran defense line of Cernes in the end, but the price paid by the demons is definitely many times higher, and the Terrans may still have to complete the strategic retreat from the Cernes war zone in the end, but a lot of blood that should not be shed, sacrifices that should not be made, and tragedies that should not happen should be avoided.
The honor of the Eagle of Cernes that he won in the Cernes War Zone, that honor is not so much an honor, but the truest portrayal of the Terran coalition forces, especially the Terran airship troops, who left the Cernes War Zone sadly.
One person killed a few Demon Wing Demons in the air, and he was able to alarm the command of the Terran coalition army in a subcontinent, and on the front line, he won the title of a person who enjoyed great prestige and honor among the Terran coalition forces, which in itself carried some irony and helplessness.
The reason for this situation is that at that time in the Cernes war zone, if you don't look at the battle between the knights of the two sides in the air, the demons in the Cernes war zone, have almost abused the Terran airships and air troops to the fullest, many times, the Terran airship troops and those brave glider pilots encountered the demons' winged demons, and what came was completely a one-sided slaughter At that time, in the Cernes theater, if one of the bravest, most casualty and most respected troops was to be selected, and glider pilots were ranked first, absolutely no one would be unconvinced.
Zhang Tie, who was the only air cavalry in the entire Sarnes Theater at that time, knew very well that the sky of the entire Sarnes Theater with a radius of millions of square kilometers was almost everywhere sprinkled with the blood of countless Terran glider pilots who had gone one after another.
The Battle of Cernes is a tragic song performed by Terran glider pilots and airship soldiers in the Weiyi subcontinent with countless lives and blood:
