Why the turbocharged engine speed up slow?
2022-09-05 09:24Turbocharged engine means that turbochargers are installed in the exhaust pipe of
the engine. The exhaust gas drives the turbine to rotate, and the turbine drives the
coaxial impeller to work, so as to improve the air intake of the engine and improve
the work of the engine per unit time. First of all, to give you a clear answer, when
the vehicle is running at low speed, the turbocharger is effective, it is normal work,
there is no doubt about it.
The starting feeling of turbocharged engine is very poor. This kind of slow start is
not that the turbocharger works slowly, but that the time required for the turbocharger
to reach a stable state will be longer. When we look at the parameters of a turbocharged
engine, it can be clearly seen that its MAX torque is 250Nm/ 1500rpm ~4500rpm.
When owners see this parameter, they will mistakenly think that the turbocharger
will not work until the engine speed is 1500rpm. In fact, this statement is very incorrect.
In fact, the whole turbocharger has been involved in the work when the engine is more
than 900 RPM. Only when the working condition is unstable, can the turbocharger work
stably and continuously when the speed of the starter reaches 1500rpm.
Started generally are owners, owners willing to speed up on the accelerator, the owners
of vehicles is expected response rapidly, but in the beginning, the engine did not reach
the state of the turbocharger and the engine response isn't very fast, the engine power
levels at this time as the same level self-priming engine, vehicle accelerating ability poor
naturally.
