Panasonic was escorted back to Changchun for interrogation, Jiang Tao did get a long-lost good news here, Jiang Tao now the most scarce resource - oil seems to have a way to solve, it turns out that the coal sunspot has not forgotten Jiang Tao's desire to find the oil field, and finally found traces of the oil field in Baicheng, near Taonan. Pen ~ fun ~ pavilion www.biquge.info

"What, coal sunspots, you really discovered the oil fields."

"Of course, I dare to vouch with my head that there must be oil under White City." Coal sunspot is also quite proud, you must know that oil exploration is not an easy thing, he took Jiang Tao to exchange the seismic exploration instrument to roughly determine the direction, and then I don't know how many boreholes were drilled to find oil in about 1000 meters, this depth if he didn't insist hard, would have been given up a long time ago.

"Great, great." Jiang Tao was also very excited to hear the news, although now relying on coal-to-oil technology to produce a small amount of gasoline, but these gasoline costs are high, and the loss is huge, it can be said that if it is not for the maintenance of a small number of mechanized troops, Jiang Tao will not use this thankless method, now that the oil field has been discovered, as long as it can be successfully exploited, a large amount of oil can be obtained, to be honest, Jiang Tao is very reluctant to use gasoline as the power of mechanized troops in the northeast, compared to gasoline engines, The power of the diesel engine is greater, and the calorific value of diesel is high, so the volume of combustion of the same mass releases more energy, and more work is done when doing the power stroke, and it will be more fuel-efficient to use diesel as the power than gasoline. It can reduce the pressure on logistics.

Considering the processing technology, the structure of the diesel engine is simpler than that of the gasoline engine, and it is more suitable for mass production. Moreover, the maintenance of diesel is easier and the life of the diesel engine is longer than that of the gasoline engine. However, in the cold conditions of the Northeast, some diesel fuel with a low enough grade will freeze, resulting in the vehicle being unable to start, so the better solution is to add ethylene glycol as antifreeze.

However, Jiang Tao's coal-to-oil technology can only synthesize gasoline, but he is helpless against diesel, but now after the discovery of oil fields, as long as the petrochemical plant is built, a large number of gasoline, kerosene, diesel and other liquid fuels and asphalt can be obtained through petrochemical technology. It can be said that the discovery of oil fields means that Jiangtao is industrialized, and the process of mechanization is greatly accelerated.

Jiang Tao immediately began to order the smelter to make a batch of railroad tracks, and urgently lay a small railway from the oil field to the arsenal to facilitate the transportation of materials and personnel, and also to use the underground oil pipeline he built as a cover.

The railway, which is less than 50 kilometers long, was laid in no time. Coal Heizi, who received Jiang Tao's strong support, obtained the screw pump oil production system exchanged by Jiang Tao, and took this system to the oilfield to arrange some series of drilling and drilling matters like a treasure. Jiang Tao was also afraid of an accident, so he asked Wen Jun to take people to garrison near the oil field.

As for Jiang Tao himself, he had long been eager to build a mechanized army, so he naturally devoted himself to intensive research and development. However, this mechanization is not a motorcycle, Jiang Tao plans to design a mechanized equipment that can cooperate with infantry operations and provide certain fire support for infantry while having a certain transportation capacity. Because it is necessary to take into account various factors such as carrying and fighting at the same time, it seems that both tracked and wheeled types are not suitable. The off-road ability of the tracked vehicle is better, but the load weight is limited, and the life of the track, especially in the off-road environment, is shorter, and the production cost is also higher than that of the wheeled vehicle. The life of the wheels is also higher than that of the tracks, and the weight of the wheeled vehicles is higher, but the terrain that the wheels can traverse at high load weights is very limited, and the ability to walk in bad weather is much less than that of tracked vehicles. Therefore, Jiang Tao resolutely chose to hybridize the two - using the half-track type as the chassis.

Jiang Tao's idea is simple, using the wheeled type as the front part, which is easier to control and steer than the crawler type, and the second half of the track style can pass through the harsher terrain. It is undoubtedly suitable for the terrain of Tohoku with perennial snow.

In order to be lazy, Jiang Tao directly used the front section of the vehicle to use the structure of the truck, the second half of the tractor structure similar to the tractor, and added 4 pairs of small load-bearing wheels below the track system to bear the weight, this track system is thanks to Chen Haisheng's contribution, Chen Haisheng left Fengtian before the information of the arsenal was brought out, including the information about the imitation and maintenance of the French Renault F-17, Jiang Tao directly reduced the load wheel of the track, and used the rubber track belt to produce, anyway, the oil is there, Synthetic rubber is not too difficult to react to, although synthetic rubber is a little worse in quality than natural rubber, but it can be used improvised.

As for the weapon system, it is more diverse, and can be equipped with machine guns, mortars, and some small-caliber rapid-fire guns, such as the 37mm infantry gun of the Japanese Taisho 11 in France, which can also be carried on the vehicle. Used as a mobile artillery.

But what Jiang Tao didn't expect was that there was a problem with the engine, because it was necessary to install armor and weapons, which led to a serious increase in the weight of the body, and the truck engine that was originally intended to be used directly could not provide enough power for the half-track drive system, Jiang Tao simply gave up the original engine and planned to study a diesel engine as a powertrain.

The working process of a diesel engine has many similarities with a gasoline engine, and each working cycle also goes through four strokes: air intake, compression, work, and exhaust. As I said before, the power of the diesel engine is generally greater than that of the gasoline engine, and the structure is much simpler than the gasoline engine. This task was honorably handed over to Hu Jun by Jiang Tao.

"Hu Jun, what about this diesel engine, much simpler than the gasoline engine, don't worry, the main difference between them is to remove the spark plug of the gasoline engine, as long as the piston is close to the top dead center, the high-pressure pump on the engine injects diesel into the cylinder with high pressure, and the diesel oil forms fine oil particles, mixed with high-pressure and high-temperature air (when the air in the cylinder is compressed to the end, the temperature can reach 500-700 °C, and the pressure can reach 40-50 atmospheres), the diesel will be mixed and burn by itself, and expand violently. Generate explosive force and push the piston down to do work, so your key is to improve the injection device so that the diesel fuel he sprays is more uniform and can be better mixed with the air.

"So it's okay for you to hand over something as simple as that." Jiang Tao is skillful in throwing pots. Hu Jun was naturally deeply moved by Jiang Tao's "trust" and agreed in one bite.
