Who says a three-cylinder engine isn’t right? After reading this, you have no reason to reject it.

Speaking of the three-cylinder engine, I believe that the first time you think about it is the “God Car” such as Shali and Alto. I think they were all “famous” in the domestic car market. However, because of its own certain defects, jitter and noise issues have not been solved, and the three cylinders have gradually been forgotten by everyone.

However, because of its own certain defects, jitter and noise issues have not been solved, and the three cylinders have gradually been forgotten by everyone.
However, there are still many consumers difficult to accept the three-cylinder engine and even think that the manufacturer is deliberately replaced with a three-cylinder engine to save costs. In fact, the three-cylinder engine still has many advantages over the four-cylinder engine!
1, less mechanical friction because the three-cylinder mechanism is simple, the mechanical friction surface is also relatively small, the three-cylinder engine is less than the four-cylinder engine a set of piston connecting rods, the opening and closing mechanism of four intake and exhaust valves, crankshaft and camshaft It has also become shorter. These components are the bulk of the engine friction loss. Therefore, the mechanical wear loss becomes smaller and the engine thermal efficiency is improved in disguise.
2, small size, light weight
Because the displacement is small, the cylinder is also one less, so the weight of the three-cylinder engine is lighter, which brings great convenience to the later maintenance. At the same time, the light weight of the engine and the small clairvoyance are also in line with the general trend of vehicle light weight, reducing the vehicle load and bringing a more lively operating experience! And the three-cylinder engine also saves the space inside the hood and can do better in safety.
3, better low speed torque
Compared to a small-displacement four-cylinder engine, the three-cylinder engine is obviously better powered than a small-displacement four-cylinder engine. The smaller the number of cylinders in the same engine, the lower the torque. The larger the volume of each cylinder, the larger the cylinder length and stroke, which means that the higher the torque at low speed, the lower the torque of the three-cylinder booster engine with the same displacement will perform better than the four-cylinder booster engine.
4, smaller turbine delay
In fact, under the current turbine trend, the most urgent problem is the delay problem of the turbine. The three-cylinder engine has better low-speed torque and smaller turbine hysteresis than the four-cylinder engine. There is no exhaust interference in the three-cylinder engine and it is easy to drive the turbine rotation. Therefore, in the past, BMW made the exhaust pipe of the N55 3.0 T single turbine engine into a double worm tube, one group per three cylinders, in an effort to reduce turbine hysteresis.
5, low fuel consumption, save money
Because the displacement is small, the power output is less, then the fuel consumption gap will be greater, so the three-cylinder engine is more fuel-efficient than the four-cylinder engine! And now the three-cylinder engine is still constantly upgrading, and the fuel consumption may be lower later!
