Xiao Weiguo began to design and develop the overall arrangement of the subsystem of the two tanks, first of all, the tank engine, of course, the original high-power diesel engine, these two high-power diesel engines also need to be developed from the beginning, this development task Xiao Weiguo decided to hand it over to BMW to do, one is because it will soon merge with the Dragon Soul Ordnance Industry and become a member of the Dragon Soul Ordnance Industry, so that it is more convenient to coordinate and manage, after all, the high-power diesel engine is the key to the success of the new tank, Without these two high-power diesel engines, the new tank could not walk and became a pile of scrap metal. Second, BMW does have a strong strength in the engine, although it used to be mainly for aviation gasoline engines, but to change to develop diesel engines, it is not too difficult, as long as Xiao Weiguo a little bit of allocation, they can design and manufacture two high-power diesel engines in the shortest possible time.

Messerschmidt was a little puzzled and said, "Philip, why do you have such a soft spot for diesel engines?" Is it too risky for a company like BMW, which is mainly engaged in aviation gasoline engines, to develop diesel engines? ”

Xiao Weiguo smiled and said, "Dear Dr. Willy, don't worry! I'm sure they can do it! The diesel engine is a more fuel-efficient, high-power engine that is best suited for tanks. Back in 1897, the practical diesel engine was invented by the Germans. The French-born German engineer Diesel Diesel developed the four-stroke diesel engine at that time, which attracted attention because of its obvious improvement in thermal efficiency, but because the early diesel engine used compressed air jet diesel, the attachments were large and bulky, so they could only be used for fixed work. It wasn't until 1922 that it was the German engineer Bosch who founded a company specializing in the development of engine fuel injection equipment. The invention of mechanical fuel injection device, such a miniaturized new fuel injection device appeared, in the past few years there appeared small, high speed and suitable for land vehicles of diesel engine, due to its inherent high efficiency and fuel-saving advantages, began to be widely used, such as engineering vehicles. Although the diesel engines developed by various countries are now low in power. Models with lower performance, but that doesn't mean we can't develop high-performance diesel engines with high power! Although it is easier to obtain more power than diesel engines, and some countries have directly changed aviation gasoline engines to tank power, the advantages of diesel engines are far inferior to gasoline engines. In the future, the development direction of tank power must be high-power diesel engines, and we must stand at a higher starting point in order to leave others far behind. ”

Messerschmidt's frown loosened slightly, and he asked, "Philip, are you sure you have a solution to the current problems in the development of diesel engines?" ”

Xiao Weiguo nodded and said, "Not bad!" We are designing and manufacturing two new tanks that will not lag behind for 20 years, and we are also developing two high-performance diesel engines that will not lag behind for 20 years. We want to increase the power per unit volume of the diesel engine as much as possible. Tongjin also needs to improve the reliability of this diesel engine. For example, in the overall structural arrangement, you can adopt a V-shaped 12-cylinder compact layout, crankcase, cylinder block, cylinder head, fuel injection pump, generator, etc. The second is to use our advantages in high-strength aluminum alloy materials to use as many aluminum alloy parts as possible, and reduce the weight of the engine as much as possible on the premise of ensuring the structural strength of the engine, such as the cylinder block, cylinder head and crankcase, and even the engine block may be made of aluminum alloy. Tanks with diesel engines are more fuel-efficient. This means that it has a longer combat range, which is determined by the technical characteristics of the engine. Because compression-ignition diesel engines have a higher energy conversion ratio than ignition gasoline engines. The energy consumption is about half that of a gasoline engine. The low-speed torque of a diesel engine is greater than that of a gasoline engine, and with the same displacement, a tank with a diesel engine will be more maneuverable. Compared with the gasoline engine, the diesel engine has a simple structure, but more reliable than the gasoline engine, and the service life is more than 50% higher than that of the gasoline engine. ”

Karl laughed: "Philip, it seems that there is no technology on the tank that can stump you!" And what about the gearing? Who should we leave to do it? ”

Xiao Weiguo said confidently: "Of course. We want to develop the most advanced tank in the world, how can we do it without technological superiority? We might as well hand it over to Porsche for the transmission of the new tank, and I believe that Porsche should have no problem in this regard! ”

Messerschmidt laughed: "I'm in favor of this!" Dr. Polscher is an absolute veteran of the automotive industry, having worked in several major automobile factories and has led the design and manufacture of many famous automobiles. I believe he will be able to design the drivetrain of our new tank perfectly. ”

In fact, before founding Porsche, Dr. Porsche served as technical director and board member of DaimlerChrysler and invented the legendary Mercedes SS and SSK supercharged sports cars. Moreover, Xiao Weiguo knew that later Dr. Polscher was also very close to Hitler, and was also involved in the development of the VK4501(P) and VK4502(P) heavy tanks, the former became the basis for the "Ferdinand"/"Elephant" tank destroyer, and the latter had a turret that can be seen on some "King Tiger" heavy tanks. But the best evidence of Dr. Bolscher's relationship with Hitler is the Rat super-heavy tank, which, in Guderian's words, is entirely a monster created from the fantasies of Hitler and his advisers. The advisor here is Dr. Polscher, who was the head of the German Tank Committee at the time and strongly advocated the development of super-heavy tanks.

Xiao Weiguo said with a smile: "Dr. Porscher's ability is undoubted, his Porsche company is also strong, and Volkswagen has a close relationship and can provide reliable transmission for our new tank." Of course, the transmission design should still be led by us, because the transmission device of the new tank must be small in size, light in weight, and effectively cooperate with the engine, driving wheels and car body and other connecting parts, and also require simple structure, good manufacturing process, to be able to fully convert the power of the engine into the power of the tank forward, that is to say, the transmission efficiency should be high. For example, the tank should be able to continuously change its speed from the start to the maximum speed range, be able to adapt to the range required to drive on the most difficult conditions on a good road, and not stall in the face of sudden and large resistance.
