Three-cylinders are not welcome These car companies actually started to study two-cylinder engines

Car fans often say that “eight-cylinder is belief, six-cylinder is ideal, and four-cylinder is the bottom line.” When it comes to three-cylinder engines, they all spit their mouths and express their disdain. Stereotypes. However, when everyone has not fully accepted the three-cylinder engine, many car companies have begun to study the two-cylinder engine.

1. General 2.0T engine

According to Uncle Che, Cadillac produced the L62 V8-6-4 engine from 6-cylinder to 4-cylinder as early as 1981, while GM currently focuses on A 2.0T turbocharged engine that changes from four cylinders to two cylinders. The reason why this engine can achieve variable cylinders mainly relies on the three-stage sliding camshaft. The operation of this device can keep the valve in three states of large intake, small intake, and no intake for a long time, meaning no intake. That is, the second and third cylinders stop working, which greatly reduces the energy consumption of the vehicle.

2. Ford 1.5T engine

This engine itself is a three-cylinder engine. Who would have thought that Ford would use closed-cylinder technology to save one more cylinder in order to save fuel, that is, only Work with two cylinders. Different from the GM 2.0T engine, Ford's 1.5T engine realizes three-cylinder to two-cylinder change through a closed-cylinder control valve and a variable rocker arm, and the entire closed-cylinder switching process can be completed in just 14 milliseconds.

3. Toyota 1.5L engine

Some people may think that the two engines mentioned by Uncle Che can not be regarded as real two-cylinder engines, so this last one will definitely not disappoint everyone. , This is Toyota's 1.5L two-cylinder engine. According to Uncle Che, the engine has been installed on the overseas version of Toyota Yaris, and because the engine has a displacement of 0.75L per cylinder, the amplitude is much larger than that of a four-cylinder engine. Therefore, Toyota has equipped it with a motor. The larger torque of the electric motor makes up for the lack of starting the engine. In addition, it is said that the fuel consumption of this power system is only about 2 liters per 100 kilometers, and the fuel economy is very good.

Uncle Che believes that more and more two-cylinder engines will appear in everyone’s field of vision, and will be mainly used in hybrid vehicles to help the automotive industry save energy and reduce emissions, and create green travel. What do you think?
