Defect or perfection, inventory of the new wave of three-cylinder engines at home and abroad

No matter whether you are willing to accept it or not, the technological trend of the engine has shifted from "large displacement naturally aspirated" to "small displacement turbocharging", and even the number of cylinders of the engine has become less and less. Now the 1.0L-1.5L displacement three-cylinder turbocharged engine has become a new generation of power. Today, let's talk about the three-cylinder engine at the forefront of Chinese and foreign automakers!

　　First of all, let's talk about why most of us reject the three-cylinder engine! Briefly summarize, there are roughly three concerns: 1. Is the power performance very weak? 2. Will the vibration and noise be very large? 3. How 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, code-named TJ376Q, originated from Japan's Daihatsu, and its technical configuration was not backward at all at that time. It used a single overhead camshaft, two valves per cylinder, and a compression ratio of 9.5:1. This three-cylinder engine still left a lot of negative impressions on people: "The power of going uphill with the air conditioner on in summer", "The noise level of one of the three tenors", "The idle vibration is high"...

　　What surprises people is that the Ford 1.0T bursts out with strong power with its petite body, with a maximum power of 125Ps (92kW)/6000rpm and a maximum torque of 170N · m/1400-4500rpm! This is stronger than the previous two Xiali 1.0L engines combined, and the smoothness is comparable to the four-cylinder engine. Therefore, Ford has also won the International Engine Awards in 2014 and 2015.

　　Ford's 1.0T engine can only be said to be a fuse, and then it quickly caused a "world war" of small-displacement three-cylinder engines among automakers. GM, BMW, Volvo, PSA and other big-name automakers have entered the battlefield, and of course now more and more Chinese brand automakers are included. Why did the three-cylinder engine suddenly catch fire? In terms of performance alone, it has an inherent advantage in fuel economy.
