Why did the speed of the turbocharged engine not increase quickly when it first started
Turbocharged engines refer to the installation of a turbine at the exhaust pipe position of the engine. The exhaust gas drives the turbine to rotate, and the turbine drives the coaxial impeller to work. This can improve the intake air volume of the engine, thereby improving the engine's work performance per unit time. First of all, let me give you a clear answer. When the vehicle is traveling at low speed, the turbocharger works and works normally. There is no doubt about this!
Turbocharged engines have a very poor starting feel. This slow starting is not due to the slow intervention of the turbocharger, but rather to the longer time it takes for the turbocharger to reach a stable state. When we look at the parameters of a turbocharged engine, we can clearly see that its maximum torque is 250Nm/1500~4500rpm. When the owner sees this parameter, he may mistakenly believe that the turbocharger only intervenes when the engine speed is 1500rpm. In fact, this statement is very incorrect. In fact, our complete turbocharger has been involved in operation since the engine turned more than 900 rpm, but the working condition is unstable. Only when the engine speed reaches 1500 rpm can the turbocharger work stably and continuously.
When a car owner starts, it is usually the case that the car owner presses the accelerator hard to accelerate. The expectation of the car owner is that the vehicle reacts quickly. However, when the car is just starting, the engine turbocharger does not reach its state, and the engine does not react very quickly. At this time, the power level of the engine is like a self priming engine of the same level, and the vehicle's acceleration ability is naturally poor.
