"Three-cylinder jitter" was originally an old topic, and it was rarely mentioned again, but recently Xuanyi e-POWER used a 1.2L three-cylinder engine as a range extender, which not only reminded people of the most controversial "three-cylinder Yinglang" of that year. Now let's talk about the change in yinglang's sales from four cylinders to three cylinders and then back to four cylinders.
In October 2017, the 2018 three-cylinder Yinglang was officially launched, divided into 1.0T and 1.3T. After two months, sales quickly suffered, falling to less than 15,000 units per month. Sales began to pick up in the summer of 2018, mainly because yinglang's terminal discounts had reached more than 40,000 at this time, nearly 30% of the discount.
In March 2020, the 1.5L four-cylinder Yinglang model returned, the discount began to shrink, but sales rebounded significantly, which shows that consumers are more receptive to the four-cylinder. Even if its L2B engine is the same as the 2015-2017 model, it is quite old.
Since 2021, the sales fluctuations of Yinglang have increased, and the probability is that this generation of Yinglang has more years. The corolla, Langyi, Xuanyi and other models that are also joint venture compact family cars have completed the replacement in the past two years, and this generation of Yinglang has insisted from 2015 to 2021.
The sales volume is the most convincing, and the performance of the three-cylinder engine is indeed not satisfactory, especially in the idle stage below 1000 rpm, and the shaking is more obvious. Even after a long time of driving and the engine is fully lubricated, the idle working conditions of the three-cylinder Yinglang are still obviously shaking at red lights, and the sound is difficult to hear. Although the automatic start and stop is turned on by default after starting, the automatic start and stop does not take effect when the air conditioner is turned on, and in small cities with short red light time, the automatic start and stop is not practical. Therefore, it is better to avoid the use of three-cylinder engines.
The new X-Trail uses a three-cylinder 1.5T engine, which quietly increases the speed to more than 1,000 rpm after the bonnet is unlocked, in order to avoid the speed range where the three-cylinder engine shakes the most obvious speed range - eight or nine hundred rpm, so that the owner cannot detect such obvious shaking after opening the engine cover. This practice has no effect on avoiding jitter in daily driving, so it has been criticized.
Write at the end
Methods of energy conservation and emission reduction have been explored, small displacement turbocharging is beyond reproach, and various modes of hybridization are better, but the use of three-cylinder engines is indeed not a good way.
