Chapter 1948 Start the engine

Previous page        Return to Catalog        Next page

    In order to achieve perfect protection, the gun shield must be at least as thick as the thickness of the tank's front armor.  Even if it only blocks the front part, the weight is definitely not small, which increases the difficulty of operation.  Western tanks don't have this problem because their turrets are either hydraulic or electric.  Anyway, there is an external force, so it doesn't matter if you add some weight.  But the Eighth Route Army can't do it. The tank of the Eighth Route Army is very simple.  Whether it is the rotation of the turret or the pitching operation of the barrel, it is all realized by shaking the wheel manually.  Therefore, a high physical requirement is put forward for the tank operator. If the strength is not strong enough, it will not be able to meet the needs of use at all.

    Now if you want to pile up such a big iron bump on the barrel, it will be even more difficult for the gunner to shake the barrel.  So now hearing Ma Sanbao's words, Qin Baoshan said: "We don't use this kind of solution, we use a new way of thinking."

    In fact, when Qin Baoshan cast this kind of turret, he did it according to the turret of the 59 tank.  If this is a light tank, it is equivalent to a 62 tank.  These tanks almost all use the same solution, that is, put a plug at the root of the barrel, where it contacts the turret.  The plug directly plugs the hole, and when the barrel rotates, the plug also rotates.  No matter where it turns, it can block the hole.

    When Qin Baoshan said this plan, the eyes of the people present showed surprise, this is also possible!  Qin Baoshan helped them solve another problem.

    It is no wonder that when Qin Baoshan set up the earpiece, everyone felt that the position of the earpiece was relatively backward, and it was originally for the placement of the plug.  The thickness of this plug is quite good, and it can fully meet the protection requirements.

    In this way, Qin Baoshan solved this problem again for everyone.  There's nothing wrong with this turret.  Although Li Yunlong doesn't understand anything, he has been following everyone.  Obviously, Li Yunlong is selfish.  After this tank is manufactured, we have to beware of Li Yunlong. Li Yunlong may use an excuse to test it together, and then drive this tank away.

    ?With Li Yunlong's character, such a thing can be done, so Qin Baoshan must prevent this from happening.

    Although it is said that Li Yunlong's important task is to protect the safety of Licheng Airport, the little devil's attention has been on Chu Yunfei's side recently, so Li Yunlong has nothing to worry about. He just follows Qin Baoshan every day.  He has not learned too much cultural knowledge, but Li Yunlong is still a smart person after all, he followed the day by day to understand the structure of these tanks.

    Finally, the engine of the tank was also made.  Li Yunlong was still a little strange when he saw the roughly rectangular thing with a big wheel on one side.  Because ordinary car engines are not like this at all.  Li Yunlong also opened the lid of the car and saw the engine inside. It has a special shape, there are many lines on it, and there are intake pipes and exhaust pipes.  But the engine in front of him now has almost nothing, it looks like an ordinary iron lump.

    On this day, a month has passed since Qin Baoshan decided to build a tank. It is simply impossible to build an engine in a month, but under the leadership of Qin Baoshan, this miracle has been realized.  Qin Baoshan is simply omnipotent.  At this time, many people present are looking forward to something.

    In their eyes, Qin Baoshan also excitedly made a few gestures to the people around him: "Add diesel oil, add water."

    The front water tank was gurglingly filled with cooling water, and the rear fuel tank was also filled with diesel.  Qin Baoshan began to put the diesel in the fuel tank.  Unlike gasoline engines, if a diesel engine starts for the first time or burns out all the fuel, then the air in the oil circuit must be evacuated to start successfully.  This is the first time to start, so all the oil pipes must be filled with oil, so that the engine can be successfully started.

    This engine was designed by Qin Baoshan, so he knows it well.  He drained the oil with ease and put it in the place of the high-pressure oil pump.  All the air in the line is out, which means that all the starting work is done.  The engine oil was added first, and there is no need to refill it.  Now, all eyes are on Qin Baoshan.  What were they expecting? Qin Baoshan took out the crank while they were watching.

    Qin Baoshan stuffed his crank into the starting part of the engine.  Hold the rocker with your right hand and press the decompression handle with your left hand.  This decompression handle is also Qin Baoshan's original idea, and there is no such thing as an engine in this era.

    Diesel engineThe compression ratio is very high, so if you shake the crank from a standstill, when the piston enters the compression process, there will be a strong reaction force.  It is difficult for ordinary people to shake the crank handle beyond this position.  If you want to get the engine running smoothly, you need to reduce this pressure.

    The solution is also very simple, that is to set a decompression handle on the valve.  When pressed down, the valve opens slightly.  This is equivalent to letting the engine cylinder leak air.  Of course, this will hinder the ignition of the engine, but it can make the engine run correctly. Only after the crank is cranked to a sufficient speed, the decompression handle is released to complete a power stroke, and the engine can be started normally.

    The start of this single-cylinder engine is completely different from the start of a car engine in this era.  The car engines of this era are all multi-cylinder engines, so do one action when starting: shake the handle and turn half a circle.  Start it if it can be started, and restart it if it can't be started.  But Qin Baoshan's engine needs to be repeated countless times, and it also needs the help of a decompression handle.

    Now it is up to Qin Baoshan to do this demonstration first.  I saw Qin Baoshan pressing the decompression handle with his left hand, and holding the crank with his right hand, and began to turn it faster and faster.  The speed of the flywheel on the opposite side was also getting faster and faster, the inside of the engine began to make noises, and the exhaust port of the engine also whirred.

    Seeing that the speed was enough, Qin Baoshan let go of his decompression handle.  Continue to exert force with the right hand, and it depends on whether it can be successfully activated.  After he let go of the decompression arm, puffs of black smoke came out from the exhaust pipe, and Qin Baoshan continued to shake the handle hard.  One lap, two laps, three laps, and finally heard the familiar sound from the engine.

    This voice is earth-shattering!  (Remember the site URL: www.hlnovel.com
