Can Toyota, the engine leader, achieve 100% thermal efficiency in the future?What are the consequences


Car engine technology, now is quite mature, but for the energy efficiency of engine, is the higher thermal efficiency, also represents the efficiency of the engine fuel into kinetic energy is higher, it also represents the technique level of the engine, which of course is to measure engine stand or fall of one of the indicators.We all know that Toyota engines have a thermal efficiency of forty-one percent, so it can be said that the engine technology is quite advanced.And some friends will think, can this thermal efficiency reach 100 percent?Can you call it advanced even if you’re not even 50 percent there yet?Actually internal combustion engine is known to all, basic it is through the nozzle spray, repass piston vacuum compression combustion, instant will produce large amounts of heat, which will promote the engine gear to run connecting rod, and then through the drive shaft and transmission control, and transfer power to the vehicle, to produce power, is the inevitable result of combustion heat loss,And this is its unique logistics characteristics, which is generally difficult to change.Let’s look at the car itself, the thermal efficiency of one hundred percent, is that there is no any energy loss, and the engine will not raise the temperature because run, if after a few hundred kilometers run temperature remains the same, you can save the cooling system, warm wind also can’t normal use, will not make any noise, such as jitter,There is no light when the fuel burns.Because of the full combustion of fuel, the carbon footprint and emissions produced are greatly reduced, and the consumption of fuel decreases in a straight line.In terms of the exterior of the vehicle, if the thermal efficiency can be achieved 100 percent, a lot of existing physical conclusions will be overturned again, so that a series of mechanical equipment will therefore change, after this simple understanding, then it is not difficult to understand why far from 100 percent.But what is the main function of this thermal efficiency?In this way, we can understand that the higher the quality of thermal efficiency, which means the engine will be more powerful, but also lower fuel consumption, emissions will be more environmentally friendly.At present, in the automotive industry, the majority of gasoline engines, the ratio of thermal efficiency is generally maintained at about 30%, the performance of the engine exceeding this value is more outstanding, fuel saving and environmental protection.To know that at present in the world’s mainstream fuel engine, thermal efficiency is generally at the level of 30 to 38 percent, can exceed 40 percent is already an excellent performance.It is true that there are companies like Toyota that can break 40 percent, but they are also weak.Mazda’s Skyactiv-X engine has a theoretical thermal efficiency of 48 percent, which is enough to wow the world.But in fact, even if it is a motor, it can not improve the energy conversion efficiency to 100 percent, and the theoretical transmission efficiency of the motor direct drive system is very high, in theory, it can only reach 95 percent.And we all know that friction between components consumes energy, so we need to eliminate friction.In addition, the engine generates high heat when it is running. In order to avoid cylinder explosion, the cooling system needs to be cooled and part of the heat is taken away, so we have to destroy the cooling system.Finally, after combustion, the exhaust gas will be discharged through the exhaust pipe, and these exhaust gases are heat, but also belong to the consumption of energy, so we have to eliminate the exhaust system.Because car manufacturing material is not able to one hundred percent under high temperature, and fuel in the combustion process, in a lot of link also produces energy loss, so the first is the fuel itself is no way to completely full burning, this also look at the engine adopt what kind of technology, will also not completely avoid burning loss is reduced.The second is the high temperature generated when the fuel is burned. In order to control this temperature, the cooling system needs to be coordinated, so there will be cooling loss.So, in theory, 100 percent mass-energy conversion can be achieved through the annihilation of positive and negative matter to convert all fuel into energy.If such an engine could be achieved, the car would probably have to be refuelled once in its lifetime, but not too much.However, this is only possible in theory, even if our controlled fusion technology is mature, it can be miniaturized, so in the process of converting into electricity or kinetic energy, there will be inevitable loss.
