    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 appearance at the moment  His body shape and whole person were like a violent machine from ancient times. Looking at his murderous bald head that almost had the words "I am the boss" written on his head, the five people in the room all opened their mouths.  "Thisis thisa real personinvented by yourself?" The oldest-looking old man in the room stared at Zhang Tie in amazement 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 the real person" The old man was so nervous that his tongue was tied. The more nervous he was, the more awkward he spoke.  He became more and more nervous. In just a few seconds, the old man's forehead was covered with beads of sweat as big as soybeans.  "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 both impressed and shocked. They didn¡¯t expect that the real person is a versatile man in both civil and military affairs, and is even proficient in mechanical design. It¡¯s really amazing. " At this time, the old man actually spoke up!  It's Sun Qiming.  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 so 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 help others when they were in trouble.  From this, it can be seen that Sun Qiming is kind-hearted and tolerant. This makes Zhang Tie look at Gao Sun Qiming again in his heart and feels that the man his junior sister Lu Shasha is looking for is not bad.  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¡¯t 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 knight¡¯s long lifespan and strong mental power, 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, but these knights are not famous for this.  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, the thing invented by Zhang Tie was really amazing 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 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 started to explain to these people while pointing at the drawings.  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.  It has 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 engine before the catastrophe, because  It generates a lot of heat during combustion, and the entire engine will be at an extremely high temperature during operation. When the engine temperature is high, it will even affect the operation of the engine. Therefore, the engines before the Catastrophe had to be equipped with  Various water-cooling or air-cooling systems are used to cool down the engine, allowing the engine to cool down while working. Many internal combustion engines before the cataclysm only need to be ignited.After running for a few minutes, the water temperature in the water tank that cools the engine will rise rapidly and even boil. This is normal for people before the catastrophe!  " "In some documents I have seen about engines before the Cataclysm, at a certain time before the Catastrophe, drivers who drove some low-power tractors with only technician horsepower, as long as they drove the tractor, everything around them  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 avoid insufficient cooling.  Burn out the engine in time, and 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.  This is a 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 20% of the total heat of fuel combustion.  Thirty, the diesel engine is higher, it 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 100% of the total combustion heat in the cylinder.  Seventy to eighty percent, the heat used is 20 to 30 percent, and the wasted heat is 70 to 80 percent. A cooling system must be developed specifically for the wasted heat. Isn't this a joke that puts the cart before the horse? Catastrophe  Most of the previous internal combustion engines, from the beginning of their design, had huge waste and leakage defects of fuel combustion heat. Traditional internal combustion engines cannot maximize the utilization of fuel combustion energy" "I invented it.  The dual-drive engine can make up for this shortcoming of the traditional internal combustion engine to the greatest extent, and at the same time, it can 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 cylinder of the traditional internal combustion engine  ¡­¡± ¡°¡­When fuel mixed with air is 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.  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 Catastrophe. This difference is that when the fuel in the cylinder is burned, its expansion brings about power.  A large amount of it 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 to heat the steam-water cooling layer on the periphery of the cylinder wall. 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, which is different from the traditional  Compared with the cylinder of an internal combustion engine, it has several significant differences. These differences are mainly reflected in four aspects. One is the layout of the cylinder, the other is the selection of the cylinder block material, and 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 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 Earth Knight.  Identity, I began to listen to Zhang Tie's introduction attentively, and gradually his full attention was attracted by Zhang Tie's introduction.  ¡­ ¡°¡­Different from the cylinder material of an ordinary internal combustion engine, the cylinder material of this engine ensures wear resistance and hardness, and at the same time, in order to smoothly transfer heat energy from the combustion chamber to the water-cooling layer next to it, it must also have  It has extremely high thermal conductivity. Therefore, according to Fourier's law of metal thermal conductivity, it is calculated that the best material to use for this cylinder block is ultra-dense double-hard triple-pole aluminum alloy. This aluminum alloy should also complete a four-phase heating in the water-cooling layer.  Plating and spraying, this process is consistent with the hot plating process of the water-cooled layer of the internal combustion engine used in many high-end cars" "Because the exhaust pipe of the internal combustion engine also takes away a lot of heat, so the engine's  The layout of the exhaust pipe is somewhat special. It adopts the design idea of ??surround and inline shape. In this way, after the engine is started, the high-heat engine exhaust gas in the exhaust pipe can be used to complete the secondary operation of the steam in the steam power system.  Heating" "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 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 has undergone two-stage turbocharging.Due to the efficiency enhancement of the device, its independent output power can reach 940 horsepower, while the independent output power of the steam power part driven by the external combustion engine is 610 horsepower. These two different sets of output power can be used as independent  Used separately, 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, and the output of a certain aspect can be changed in different situations and time periods.  To the maximum, without connecting the steam weapon module, because this era has brought about certain transcendences in metallurgical materials that 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 that Zhang Tie once had, Zhang Tie explained it very attentively, and could even be called meticulous. And when he was explaining this engine, Zhang Tie was here, and  His heart had already flown to the Sernes war zone, which was once filled with gunpowder smoke and blood-stained sky 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 something in his mind.  Assuming that if there had been such an engine and propeller aircraft driven by such an engine in the Cernes Theater, what would have been the outcome of the Cernes Battle?  Would it be better? The answer is unquestionable. If there had been such an engine and an aircraft could have been manufactured with such an engine, then the outcome of the entire Cernes War Zone would have definitely been rewritten.  It may still be possible to break through the human defense line 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 Sernes war zone in the end, but a lot of blood should not be shed.  The sacrifices that should not have been made and the tragedies that should not have happened should have been 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 a human alliance.  , especially the most realistic portrayal of the tragic departure of the human airship troops in the Sernes war zone. One person killed several demon wing demons in the air, and was able to alert the human coalition command of a subcontinent, and gained victory on the front line.  A title that enjoys great prestige and honor among the human coalition, which itself has a sense of irony and helplessness. The reason for this situation is that in the Sernes war zone at that time, if we did not look at the knight-level force of both sides.  As for the aerial battle, the demons have almost completely beaten the human airships and aerial troops in the Sernes war zone. Many times, the human airship troops and those brave glider pilots encountered the demons' winged demons.  What awaited was a one-sided massacre At that time, in the Cernes War Zone, if one were to choose the bravest, highest casualty rate, and most respected military branch, glider pilots would be ranked first. Absolutely no one would  Not convinced.  As the only air cavalry in the entire Sarnes war zone at that time, Zhang Tie 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 Cerness is a tragic song played by human glider pilots and airship troopers on the Hawaiian subcontinent with countless lives and blood
