whether you want to accept it or not, the technology trend of the engine has changed from "large displacement naturally aspirated" to "small displacement turbocharged", and even the number of cylinders of the engine is becoming less and less. now, the 1.0l-1.5l three cylinder turbocharged engine has become the power of the new generation. today, let's talk about a wave of three cylinder engines at the forefront of chinese and foreign automobile enterprises!
first of all, let's talk about why most of us reject the three cylinder engine! to sum up, there are three doubts: 1. is the power weak? 2. is there a lot of vibration and noise? 3. what is the reliability after long-term use? many people's impressions or doubts about the three cylinder engine may be traced back to xiali (tj7100) in the 1980s.
this three cylinder engine, named tj376q, originated from daihatsu, japan. its technical configuration was not backward at that time. it adopted single overhead camshaft with two valves per cylinder and a compression ratio of 9.5:1. the three cylinder engine still left a lot of negative impression: "the power of driving uphill with air conditioner on in summer", "the noise level of one of the three tenors", "large idle vibration"
what's amazing is that ford 1.0t has a strong power with its small body, with a high power of 125ps (92kw) / 6000rpm and a high torque of 170n · m / 1400-4500rpm! this is better than the previous two xiali 1.0l engines combined, and the smoothness is also comparable to the four cylinder engine, so ford also won the international engine awards in 2014 and 2015.
ford's 1.0t engine can only be said to be a fuse, which quickly caused the "world war" of small displacement three cylinder engine among car companies. big car companies such as general motors, bmw, volvo, psa and so on have been put into the battlefield. of course, now more and more chinese brand car companies are also included. why did the three cylinder engine suddenly catch fire? in terms of performance alone, it has inherent advantages in fuel economy.
