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.

柴油策念头的功率晋升首要靠的是增压器，若是不以废气驱动的涡轮增压器为主的手艺线路动员的话，功率晋升便是一句废话，由于涡轮增压的呈现，才转变了排量决议能源机能的汗青！现阶段柴油策念头的能源机能调校便是增压器与策念头的机能婚配题目。

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.

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.

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.

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
