Why do many people say that you should never buy a three-cylinder car if you can buy a four-cylinder car?

Compared with the four-cylinder engine, the three-cylinder engine has inherent noise and sway. The "congenital defect" of the three-cylinder engine is that the three-cylinder pistons cannot be synchronized, and the ignition sequence is mostly 132. During operation, the inertia force of each piston due to mechanical energy will cause the engine to run unsteadily, which is the reason why the three-cylinder engine shakes obviously.

Although it can be recognized by many people, not many people will choose to buy it. The reason is that the price will not decrease with the decrease of cylinder speed, and even more expenses will be spent on automobile maintenance.

As we all know, the higher the number of cylinders in an engine, the stronger the power it provides, but the consequence is that the fuel consumption will increase. As far as the four-cylinder power technology is concerned, it can not only provide strong auxiliary air intake, but also provide strong power during the acceleration of the car at the beginning, which is obviously different from the three-cylinder power. Power is only on the one hand, and fuel consumption on the other. Under normal circumstances, four cylinders are more fuel efficient than three cylinders. If we compare Bora (four-cylinder) and Yinglang (three-cylinder), the average annual kilometer of a car is 200,000 kilometers, and the final cost of Bora is even less than Yinglang.

Four-cylinder engines are mostly L-shaped inline four-cylinders, which have the advantages of simple structure, low failure rate, compact volume and light weight. The ignition sequence is 1243 or 1342. In operation, two groups of pistons always run at the same time, and the inertia force generated by mechanical energy generated by fuel deflagration in the cylinder can cancel each other, so the running state will be quite stable.
