                  概述:發(fā)動(dòng)機是一輛車(chē)的心臟,專(zhuān)用車(chē)中的自動(dòng)攪拌車(chē)的發(fā)動(dòng)機都是以柴油為主的,隨著(zhù)科技的發(fā)展,柴油發(fā)動(dòng)機的馬力是越來(lái)越大,今天我們就來(lái)聊一聊
                  發(fā)動(dòng)機是一輛車(chē)的“心臟”,專(zhuān)用車(chē)中的自動(dòng)攪拌車(chē)的發(fā)動(dòng)機都是以柴油為主的,隨著(zhù)科技的發(fā)展,柴油發(fā)動(dòng)機的馬力是越來(lái)越大,今天我們就來(lái)聊一聊關(guān)于攪拌車(chē)發(fā)動(dòng)機功率大小事項。
                  The engine is the "heart" of a car. The engines of automatic mixers in special vehicles are mainly diesel fuel. With the development of science and technology, the power of the diesel engine is increasing. Today, we will talk about the power of the mixer engine.
                  柴油發(fā)動(dòng)機的功率提升主要靠的是增壓器,如果沒(méi)有以廢氣驅動(dòng)的渦輪增壓器為主的技術(shù)線(xiàn)路帶動(dòng)的話(huà),功率提升就是一句空話(huà),因為渦輪增壓的出現,才改變了排量決定動(dòng)力性能的歷史!現階段柴油發(fā)動(dòng)機的動(dòng)力性能調校就是增壓器與發(fā)動(dòng)機的性能匹配問(wèn)題。
                  The power increase of diesel engine mainly depends on the supercharger. If there is no technology line driven by exhaust gas driven turbocharger, the power increase is empty talk. Because the appearance of turbocharging has changed the history of displacement determining power performance! At present, the power performance tuning of diesel engine is the performance matching problem between supercharger and engine.
                  廢氣渦輪增壓器是以發(fā)動(dòng)機燃燒產(chǎn)生的廢氣做動(dòng)力推動(dòng)增壓器的渦輪旋轉帶動(dòng)同軸另一端的壓氣機葉輪往進(jìn)氣管理打氣。說(shuō)白了廢氣渦輪增壓器就是一個(gè)利用排氣能量的氣泵往進(jìn)氣管力面打氣的一個(gè)部件,而排氣能量的大小取決于發(fā)動(dòng)機燒油的多少。
                  The exhaust gas turbocharger uses the exhaust gas generated by the engine combustion as the power to drive the turbocharger turbine to rotate and drive the compressor impeller at the other end of the same axis to pump air into the intake management. To put it bluntly, the exhaust turbocharger is a component that uses the exhaust energy to pump air into the intake pipe force surface, and the amount of exhaust energy depends on how much oil the engine burns.
                  自動(dòng)攪拌車(chē)
                  當油門(mén)小,轉速低的時(shí)候,渦輪增壓器基本上是不起作用的。這里要解釋一個(gè)名詞就是“渦輪介入轉速”就是指多少轉速渦輪增壓器才能開(kāi)始幫助發(fā)動(dòng)機出力。在此轉速之前發(fā)動(dòng)機基本上是相當于自然吸氣的,額定功率相同的發(fā)動(dòng)機排量越大則渦輪增壓器介入之前或剛剛介入時(shí)進(jìn)氣量會(huì )越多,發(fā)動(dòng)機對于增壓器的依賴(lài)性就越小,就可以匹配增壓小的渦輪增壓器,相應的小渦輪增壓器能夠更好的改善渦輪增壓器低速加速性能。
                  When the accelerator is small and the speed is low, the turbocharger basically does not work. Here we need to explain that the term "turbine intervention speed" refers to the speed at which the turbocharger can start to help the engine output. Before this speed, the engine is basically equivalent to a naturally aspirated engine. The larger the engine displacement with the same rated power is, the more air intake will be before or just after the turbocharger intervention. The less the engine depends on the turbocharger, and the smaller the turbocharger can be matched. The corresponding small turbocharger can better improve the low speed acceleration performance of the turbocharger.
                  額定功率大而排量小一些的發(fā)動(dòng)機則低速瞬時(shí)加速性能肯定會(huì )差一些,這時(shí)對于增壓器與發(fā)動(dòng)機之間的匹配就有很大的挑戰性。要保證發(fā)動(dòng)機額定功率足夠大就須用大渦輪增壓器,而大渦輪增壓器低速加速性能又不好,為了平衡二者的關(guān)系,所以就把渦輪介入轉速提前,介入轉速提前,相應的渦輪旁通泄壓閥打開(kāi)也會(huì )提前,以便更好的保護增壓器不會(huì )超轉速。
                  The engine with higher rated power and smaller displacement will certainly have poorer transient acceleration performance at low speed, which is a great challenge for the matching between the supercharger and the engine. To ensure that the rated power of the engine is large enough, large turbochargers must be used, and the low speed acceleration performance of large turbochargers is not good. In order to balance the relationship between the two, the turbine intervention speed is advanced. The intervention speed is advanced, and the opening of the corresponding turbine bypass relief valve will also be advanced, so as to better protect the turbocharger from overspeed.
                  但是不管采用什么樣的辦法,也只能部分改善它的低速性能,這一類(lèi)發(fā)動(dòng)機低速加速性能和低速油耗會(huì )比較差,額定功率輸出的經(jīng)濟性也還是差一些。因為在低速加速階段發(fā)動(dòng)機充氣系數是不足的,為了盡快提高發(fā)動(dòng)機和渦輪增壓器轉速須盡量多給油,這就是渦輪增壓發(fā)動(dòng)機低速加速油耗大的原因。
                  However, no matter what method is adopted, it can only partially improve its low-speed performance. This kind of engine has poor low-speed acceleration performance and low speed fuel consumption, and the economy of rated power output is still poor. Because the engine inflation coefficient is insufficient in the low speed acceleration phase, in order to improve the engine and turbocharger speed as soon as possible, more fuel must be supplied, which is the reason why the turbocharged engine has high fuel consumption during low speed acceleration.
