In recent years, the development of the automotive industry, three-cylinder engines quietly returned to the line of sight of the industry! But most consumers often refer to the three-cylinder machine, more or less there is some conflict, even an extreme consumer, directly to the three-cylinder machine 'Incorporating the black list of your own car. Frankly speaking, the common problem of the three-cylinder machine is that every consumer is unwilling to accept it. So even when we talk about the three-cylinder machine, 'jitter' seems to be its label.
However, Xiao Bian has to correct a misunderstanding here. It is not that the more the number of cylinders of the engine, the better the vibration will be controlled. The vibration is the balance shaft technology with the engine, the damping material of the machine foot, and the layout of the engine. Such as closely related, for less car-oriented NVH, even if the eight-cylinder, shake is not necessarily better than the four-cylinder. First of all, we must understand this, we go to a detailed understanding of the advantages and disadvantages of the three-cylinder machine.
The three-cylinder engine is in fact not a novelty. It has been accompanied by the development of the automotive industry for more than ten years. Since the invention of the internal combustion engine more than a hundred years ago, we have focused on the subject matter, taking the Ford 1.0 TEcoboost engine, in order to reduce the number of The noise and vibration of the cylinder engine, Ford uses the offset of the crankshaft and weight, resets a certain angle, plus the balance shaft, the pulley and the flywheel also deviate from a certain angle to slow down the vibration and reach the level of the four-cylinder engine. We can clearly The discovery that you want to solve the vibration problem does not depend on the number of cylinders, but rather on the balance shaft and some specific tunings.
From the perspective of the working principle and structure of the three-cylinder machine, theoretically, jitter seems to be unavoidable. Frankly speaking, this is also what many keyboarders intuitively pass to the user, plus many users from Xiali many years ago. The cheapness and jitter felt on the three-cylinder body of the TJ376 series made many people have a great prejudice against the three-cylinder machine. What we said above, the reason why the three-cylinder machine shakes, does not depend on the cylinder. The number of cars is now being used by the majority of car companies. Car companies naturally understand the attitude of consumers to the three-cylinder machine. Resolving jitters is a problem that they must solve.
Of course, I'm not praising everyone on the three-cylinder machine. On the contrary, what I want to pass on to everyone is that everyone's views on the three-cylinder machine are not necessarily extreme. If we understand it correctly, take the GM as an example. The universal three-cylinder engine uses double Mass flywheels, crankshaft rubber shock absorbers and balance shafts are used together to ease the problem of three-cylinder engine's jitter. With the advancement of technology, there are more advanced automotive technologies to solve the possible lack of power of the three-cylinder engine. These include turbocharging, direct injection in cylinders, variable intake and exhaust timing (Ti-VCT), and dual injection technologies. They have achieved great success. Therefore, consumers can not be optimistic about the three-cylinder machine. However, it is not used to deal with blackouts directly. After all, it is still a question of misunderstanding. Its jitters are not just a lack of a 'cylinder'.
