Which is more suitable for running at high speeds, a model with a 1.4T turbocharged engine, or a model with a 2.0-liter naturally aspirated engine? The obvious answer is that the 1.4T model is more suitable for running high speeds, and we can take two cars as an example, that is, the Passat with a 1.4T engine and the Camry with a 2.0L engine.
Turbocharging and self-priming engine difference between turbocharging and natural suction, is the difference between the engine's intake mode, natural suction is to directly press the air into the combustion chamber without the help of the supercharger of the air intake mode, turbocharger is to rely on the turbocharger, increase the combustion chamber intake of a way. From the power point of view, the self-priming engine is more smooth, but it requires a high speed to burst the peak torque; due to the presence of turbo hysteresis, the turbocharged engine has relatively poor ride, but the peak torque comes early.
From the perspective of fuel economy, many people say that turbocharged engines are not fuel-efficient, just a lie of the merchants. In fact, the turbocharging itself really cannot improve fuel economy, but the turbocharged engine can reach the peak torque at a medium and low speed due to the wider torque platform and the low and medium speeds, so it can be in the high efficiency range for a long time, and finally achieve the effect of fuel saving. The self-priming engine has the highest efficiency in the high-speed and high-load range, if you usually drive the Buddhist system is not more fuel-intensive than the turbocharged engine, but once you need power, you need more deep throttle, sacrificing a certain fuel economy. Power parameter comparison Then we look at the power parameters, passat equipped with this EA211 engine, the maximum horsepower 150Ps, the maximum torque 250N .m, the Camry's maximum horsepower 178Ps, the maximum torque of 210N .m, from the parameter point of view, although the displacement gap is 0.6L, but the Camry and Passat have their own advantages, the Camry's horsepower is stronger, and the Passat's torque is stronger. From this point of view, the two cars seem to have little difference, but we tend to overlook an important parameter when looking at the parameters, the maximum torque speed range.
The 1.4T Passat maximum torque rpm range is 1750-3000 rpm, while the 2.0L Camry maximum torque rpm range is 4400-5200 rpm, and the daily driver who will hit the throttle with one foot to 4400 rpm, so at low revs, the 1.4T Passat has more torque and more power. If you run at high speed, the gear at this time is generally the highest, if you step on the accelerator at this time to overtake, you can obviously feel that the 1.4T Passat has more staying power, and the fuel consumption is also lower.
In summary, 1.4T and 2.0L engines, or naturally aspirated and turbocharged engines scaled up to small and medium displacements, the smoothness of self-priming engines is more suitable for urban transportation, while the low-turn high-torque of turbocharging is more suitable for running at high speeds. As for you saying that the 5.7L V6 self-sucking, I can only say that there is money willful to make!
