There is a saying in the automotive circle that turbo cars run at high speeds than self-absorption, is this really the case? I have to admire some of the folk who understand the ability of the car emperor to be blind, in fact, on the contrary, running high-speed turbo models is more suitable for more calm, why say so?
Turbocharging can improve intake efficiency
The difference between a turbocharged engine and a naturally aspirated engine is simply the difference in the supercharger. In the case of a certain engine displacement, if you want to increase the output power of the engine, the most effective way is to provide more fuel combustion. However, it is easy to provide more fuel to the cylinder, but it is difficult to provide a sufficient amount of air to support the complete combustion of the fuel, which is difficult to do with the traditional engine intake system. Boosting technology is a way to improve the air intake capacity of the engine. The supercharger compresses the gas entering the cylinder in advance, so that the gas entering the cylinder is denser, the intake volume is improved, the purpose of increasing the engine power is achieved, and the power and torque of the engine are finally improved.
Turbocharging is more suitable for running at high speeds
In fact, compared with naturally aspirated engines, turbocharged engines are more suitable for running at high speeds, and we can compare the two engines to know. Taking the turbo engine of the same displacement is bullying the naturally aspirated engine, which we can see by comparing the Volkswagen 1.4T engine with the Toyota 2.5L engine. Volkswagen's 1.4T engine is divided into two power versions, the low-power version has a maximum power of 96 kW and a peak torque of 225 Nm; the high-power version has a maximum power of 110 KW and a peak torque of 250 Nm. This engine reaches a peak torque of 225 N·m at about 1400 rpm, which means that the peak torque comes very early, which will make the whole car more energetic, and the maximum torque range is 1400 to 3500 rpm.
Toyota 2.5L engine has a maximum power of 131Kw, a maximum torque of 221N.m, and a maximum torque speed of 3600-5200 rpm. In terms of parameters, this engine is more advanced in the maximum parameters, the torque difference is not much, and this power is no problem to run at high speed. But the difference in the maximum torque platform can be large. Generally speaking, running high speed, the car will rise to the highest level, the speed is generally between 1600-2500 rpm, for the Volkswagen 1.4T engine, when running high speed, this speed is exactly the maximum torque range of the engine, you can more calmly complete the acceleration overtaking, but for Toyota's 2.5L engine, the speed at high speed is less than the maximum torque, and it takes a foot of throttle downshift to increase the speed, and the maximum torque can burst out. Therefore, when running at high speed, turbocharging will be highlighted by its wide "torque plateau".
Therefore, the natural suction car is more suitable for running high-speed than the turbocharged car is a rumor, how to try it specifically, if you often run high-speed, it is more recommended to buy a turbocharged engine. If there is more driving in the city, the natural aspirated car will be smoother and more suitable for you.
