Who is the inventor of turbocharger?
First of all, for this sentence: "The intake valve of a four-stroke engine is closed during intake, compression, work and exhaust, except at the end of the intake stroke and exhaust stroke. During the time when the intake valve is closed, the inertial turbocharger continues to work at a high speed of 20,000 rpm depending on its own inertia, thus achieving the purpose of increasing the intake pressure. " The engine throttle is located above the cylinder head and is usually arranged in parallel with the exhaust valve. As for the "position of inertial turbocharger", I think it can only be installed in front of the throttle and inside the intake pipe. Looking at the air flow in the intake pipe, I think it seems difficult to reach the inertia of 20000 rpm. Reason: Generally, the turbocharger needs to be at a high speed, so that the exhaust gas can drive the turbine to reach a very high speed. The speed of exhaust gas in the head is much higher than that of air intake to meet the demand of negative pressure air intake. Then, respond to this sentence: "A four-stroke engine can work continuously at a constant speed for the following reasons. We know that only one of the four strokes of a four-stroke engine is a power stroke, and the other three strokes are not power strokes. The operation of these three strokes is completed by transferring the kinetic energy generated by the power stroke to the engine flywheel and storing it in the flywheel, which is driven by the flywheel. This is the same as the working principle of an inertial turbocharger. " Let's talk about the working principle of the engine: the engine is divided into intake stroke, compression stroke, ignition stroke and exhaust stroke. The actual work is the ignition stroke. First, the intake valve opens and the intake stroke begins. The air in the intake pipe enters the cylinder, the piston moves to the bottom of the cylinder, and then the throttle valve closes. Driven by the flywheel, the piston begins to move to the cylinder head, compressing the air in the cylinder. When it can no longer be compressed, the nozzle injects oil, the spark plug ignites and the ignition stroke begins. Under the deflagration of gas, the piston moves to the bottom of the cylinder to do work. When the stroke ends, the exhaust valve opens and the piston continues to move to the cylinder head under the action of the flywheel. We can see that the function of flywheel here is to store energy, convert kinetic energy into moment of inertia, and provide necessary energy when the engine is not doing work. By the way, correct this person's concept: not inertia, but moment of inertia in scientific language. I'll give you a lesson today. It doesn't matter. It's free. From the perspective of energy conservation, the engine speed should not be increased, but we should not forget that the engine has a power stroke, and the work done each time in this power stroke is not a fixed value, while the energy supplement required by the engine without a power stroke is a fixed value. This can explain why the car can run faster and faster by running the engine on the premise of saving energy. Assume that the turbine of dhyjm acts as a flywheel. In the last post, I analyzed the relationship between engine intake B: A.
