China Power 中国 車 car is driving China - BYD Auto
The engine of the Chinese brand's first have a look at geely, Roewe, Chery, Changan this car.
Nowadays, more and more cars carrying supercharged smaller engine displacements become smaller, less the number of cylinders, it seems to have become the trend of future development, our Chinese brand is no exception, many brands have launched a small supercharged models to meet market demand, and then show how these models and brand joint venture is still a gap.
This article, we need to talk, led by geely, Roewe, Chery, Changan several supercharged models smaller of how power.
Auto show in 2013, Geely exhibited two direct-injection turbocharged engines, and below the machine code for the beta JL 4 turbocharged g13td is to mark the EA111 player, can also be regarded as money geely motor 1 3 T .
Continue Emgrand March 1 T engine, and can be considered low with the beta 4 JL g13td, performance than the original show prototype so strong, but gains in cheap and durable.
The motor when driving the linear output power, low epidemic torsion, until the medium can feel the force, after the high-speed section and the acceleration was low, and adjust the continuously variable transmission, said he is killing all the passion of driving too.
Although the engine and the degree of transmission correspondence is quite good, treat household enough, but the category turbo, almost average appeared on it is difficult for us to realize the pleasure turbo, can feel only approximately linear suction natural, for this friend who loves supercharged models, is a shame, but for the continuation of the house completely comfortable friend without problem.
We just list new models soon, this paragraph of time has attracted many eyeballs, the biggest feature is to wear a T May 1 turbo engine, and a younger sports on, and locate SPORT.
First of all say that the supercharged engine, it is the development of a new engine T chery May 1, you can use it as a tiggo or dingle arrizo 7 and 7 on the improved version 1 5 T E4T15 the E4T15B code also confirms this.
Started at the beginning, you may feel the engine power is linear, and Emgrand 1 above 3 T, you just think he's a naturally aspirated 1500 RPM keeping the ball on a pedal, turbine concerned that a sudden feeling delay I tried several times, he felt like a low speed in a good car self-priming, even laboriously feel the existence of the turbine feeling is also very low.
Also can see from the data, the motor of the adjustment is not radical, even compared to 7 on the 1st 5 engine T tiggo or Dingle, maximum power also reduced 5 this does not mean it didn of importance in the engine acceleration process between 2500-3000 - RPM will be an explosion under 80 km h, you can still feel the speed is relatively easy, but when traveling at speeds of over 80 km h, power low problems are inevitable.
The transmission CVT is always corresponding powertrain is still smooth sexual orientation, so that the engine is not as sport, but the overall performance is still noted.
calibration gas is not positive, the accelerator pedal down more than a quarter, just may be the rise of speed.
This engine at 1700 RPM can obviously feel the operation of the turbine, the optimum power varies from 2000.
4000 RPM, if the exceeding of the speed range, it is relatively easy, wait after more than 100 km of speed h acceleration capability slightly again, this too and the size of the movement, not suitable for the period higher acceleration.
Is one of the recent heat models Roewe i6 includes a set 1 7 5 T powertrain DCT, due to the use of the dual clutch, so that its dynamic performance is linked and the preceding two paragraphs are not the same that the model of the CVT.
The engine 1 of 5 T and RX5 is the same, but the book data, a maximum of 169 ps hp, maximum torque of 250 M n, is indeed very good, feeling so real how.
I6 stronger power motor makes everyday driving feel lighter, speed gearshift maintained at about 2000 rpm, more comfort Change is good, but the speed is still lower than the same use of common models dual clutch, and compared and the mainstream aT transmission, it is not a family car with a moving speed for comfort, I think it is worth, but the low i6 speed, the condition of traffic transmission performance of the machine is not so good, stop-and-go at low speed, the combination of power and off, presents the most obvious features dual-clutch, and 1 2, can cover or it will be perceived.
If i6 May 1 engine T gives me the greatest feeling is, it really is like a performance turbocharged engine, as also mentioned above, the engine 1 3 T and arrizo Emgrand 5 SPORT May 1 T engine, meaning that gives a person is more like a naturally aspirated engine, the Roewe i6 May 1st engine T on the calibration ability significantly better, turbo material, and corresponding dual-clutch gearbox, it is natural that the dynamic performance is better.
By analyzing four above example, we see not too difficult, now China brand smaller turbocharged there is room for improvement, whether dynamic adjustment or a complete set of corresponding maturity powertrain, the degree of tacit understanding, brand and joint venture there is a gap, but at the current level and rate of development, many Chinese brands have done rather well.
Hope that Chinese brands can improve their own technology, based on high positions in the industry, own efforts engine, gearbox and vehicle technology, to do better.
The Chinese brand engine first take a look at Roewe geely chery Changan this, Chinese brand engine, first.
