混凝土攪拌車發動機功率如何進行選擇?

發動機是一輛車的“心臟”,專用車中的自拌混凝土攪拌車的發動機都是以柴油為主的,隨著科技的發展,柴油發動機的馬力是越來越大,我們來聊一聊發動機。
The engine is the "heart" of a car. The engine of self mixing concrete mixer in special vehicles is mainly diesel. With the development of science and technology, the horsepower of diesel engine is increasing. Let's talk about the engine.
柴油發動機的功率提升主要靠的是增壓器,如果沒有以廢氣驅動的渦輪增壓器為主的技術線路帶動的話,功率提升就是一句空話,因為渦輪增壓的出現,才改變了排量決定動力性能的歷史!現階段柴油發動機的動力性能調校就是增壓器與發動機的性能匹配問題。
The power improvement of diesel engine mainly depends on the turbocharger. If it is not driven by the technology of exhaust driven turbocharger, the power improvement is empty talk, because the emergence of turbocharging has changed the history that the displacement determines the power performance! At present, the dynamic performance adjustment of diesel engine is the matching problem between turbocharger and engine.
自拌混凝土攪拌車,廢氣渦輪增壓器是以發動機燃燒產生的廢氣做動力推動增壓器的渦輪旋轉帶動同軸另一端的壓氣機葉輪往進氣管理打氣。說白了廢氣渦輪增壓器就是一個利用排氣能量的氣泵往進氣管力面打氣的一個部件,而排氣能量的大小取決于發動機燒油的多少。
混凝土攪拌車
In the self mixing concrete mixer, the exhaust gas turbocharger is driven by the exhaust gas generated by the engine combustion to drive the turbine of the turbocharger to rotate and drive the compressor impeller at the other end of the coaxial shaft to pump air into the intake management. To put it bluntly, the exhaust gas turbocharger is a component that uses the exhaust energy to pump air to the force surface of the intake pipe, and the amount of exhaust energy depends on how much oil the engine burns.
自拌混凝土攪拌車,當油門小,轉速低的時候,渦輪增壓器基本上是不起作用的。這里要解釋一個名詞就是“渦輪介入轉速”就是指多少轉速渦輪增壓器才能開始幫助發動機出力。在此轉速之前發動機基本上是相當于自然吸氣的,額定功率相同的發動機排量越大則渦輪增壓器介入之前或剛剛介入時進氣量會越多,發動機對于增壓器的依賴性就越小,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。
Self mixing concrete mixer, when the throttle is small, low speed, the turbocharger basically does not work. Here to explain a term is "turbine speed" refers to how much speed turbocharger can start to help engine output. Before this speed, the engine is basically equivalent to naturally aspirated. The larger the displacement of the engine with the same rated power, the more the intake air will be before or just after the intervention of the turbocharger. The less the dependence of the engine on the turbocharger, the smaller the turbocharger can be matched. The corresponding small turbocharger can better improve the low-speed acceleration of the turbocharger Yes.
自拌混凝土攪拌車,額定功率大而排量小一些的發動機則低速瞬時加速性能肯定會差一些,這時對于增壓器與發動機之間的匹配就有很大的挑戰性。要保證發動機額定功率足夠大就必須用大渦輪增壓器,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也會提前,以便更好的保護增壓器不會超轉速。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,這一類發動機低速加速性能和低速油耗會比較差,額定功率輸出的經濟性也還是差一些。因為在低速加速階段發動機充氣系數是不足的,為了盡快提高發動機和渦輪增壓器轉速必須盡量多給油,這就是渦輪增壓發動機低速加速油耗大的原因
For self mixing concrete mixer, the engine with large rated power and small displacement will have poor low speed instantaneous acceleration performance, which is a great challenge for the matching between supercharger and engine. In order to ensure that the rated power of the engine is large enough, the large turbocharger must be used, and the low-speed acceleration performance of the large turbocharger 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 is also advanced, so as to better protect the turbocharger from over speed. However, no matter what method is adopted, it can only partially improve its low-speed performance. The low-speed acceleration performance and low-speed fuel consumption of this kind of engine will be poor, and the economy of rated power output will be poor. In order to improve the speed of engine and turbocharger as soon as possible, it is necessary to supply as much fuel as possible, which is the reason why the fuel consumption of turbocharged engine is high at low speed acceleration
