1. Toyota engine features: self-priming engine has high thermal efficiency, linear power output, good stability and fuel economy, but low torque and weak acceleration.
2. Features of Volkswagen engine: Turbocharged engine has strong power, strong sense of acceleration, large torque and fast speed increase, but the power output is not linear enough and the stability is not as good as self-priming.
First, the structure: Toyota likes self-priming, and the public prefers turbocharging.
1. Toyota's design idea is conservative, and the technology adopted is mature and stable. It has been concentrating on developing the power combination of self-priming and +CVT. With the increasingly severe environmental protection situation and the implementation of the most stringent national six emission standards, higher requirements are put forward for automobile engines, which should not only ensure sufficient power, but also reduce carbon emissions. It seems to be the fastest and most practical way to install turbocharger on the engine, so there are many small-displacement turbocharged engines at present, especially Volkswagen.
2. But Toyota chose the second way to improve the thermal efficiency of the engine! The thermal efficiency of Volkswagen brand-new 1.5T engine is only 37.5%, while that of Toyota 2.0L self-priming engine is as high as 40%, and that of Toyota 2.5L self-priming engine is as high as 4 1%. Toyota can be said to be the absolute king in terms of engine thermal efficiency! It is very difficult to improve thermal efficiency 1%, but research and development consumes so much manpower and financial resources. Why did Toyota do this? Obviously, the stability of self-priming engine is not comparable to that of turbocharged engine. It has the characteristics of linear power output and no turbo lag.
3. Volkswagen's pursuit of fuel economy is not so fanatical, but emphasizes large torque and strong power. 1.4T/2.0T+7-speed dual clutch gearbox has mature and stable power system, abundant power and obvious push-back feeling. Taking EA888 engine as an example, the engine adopts variable valve timing technology, which can effectively improve the intake and exhaust efficiency. Variable valve timing is mainly realized by the vane hydraulic regulator located on the intake camshaft.
Second, stability: Toyota is more stable.
The workmanship of Toyota engine is still exquisite, and some small details are well handled, especially small parts such as rubber seals, and the fit between parts is very high. It is said that Toyota considers the expansion and contraction of parts, and the engine is assembled at low temperature, and then taken out after completion. Due to the principle of thermal expansion and contraction, the parts will fit more closely and perfectly! As long as Japanese cars are maintained normally, it will not be a problem to drive for more than ten years, and the maintenance cost is relatively low. Because Volkswagen mostly uses turbocharged engines, the later maintenance is more expensive, and the turbocharging technology is not very mature. There are still many problems, and the problem of burning oil is very common. Therefore, in terms of engine stability, Toyota is better!
Third, strength: the masses are stronger.
Most friends who have driven Toyota cars have this feeling, smooth! The power output is linear. Due to the low torque, the explosive force is not very strong, and the late acceleration performance is somewhat weak. Not as direct as the power output of Volkswagen turbocharging. Can the driving experience be used? Buddhism? One word to describe it. Driving Volkswagen is a completely different driving experience. EA888 engine with dual clutch gearbox has obvious push back feeling and very strong power.
In addition, Toyota hybrid technology is also a top-level existence. The application of a number of patented black technologies has established its position as the hybrid boss, but in recent years it seems to be surpassed by Honda hybrid!
abstract
Japanese, headed by Toyota, and German, headed by Volkswagen, have excellent engine performance. Which is better? It feels really bad to compare, I can only say that each has its own characteristics and different emphases! Toyota is more durable and fuel-efficient, and the public is more dynamic. If you have peace of mind at home, it is recommended to choose Toyota, and if you pursue dynamic performance, choose Volkswagen!
