How many cylinders do you need at least for a car engine? What s the saying?

At least 4 are needed, and the engine of the car must reach 4 to be used normally, which can promote the normal start and use of the engine, and can maintain the normal driving of the vehicle.

A car engine needs at least one cylinder; Because one cylinder is also possible, but the performance will not be particularly good, and there is no stability of a 4-cylinder engine.

The car engine needs at least one cylinder, and now the market is generally a 4-cylinder engine, and in fact, the two-cylinder engine and the single-cylinder engine are also OK, but the performance is not very good, the two-cylinder engine and the three-cylinder engine shake particularly badly during driving, and the 4-cylinder engine is more stable.

A minimum of three cylinders is also required. Because all current car engines are turbocharged engines and require a lot of exhaust, consumers now have a lot of power requirements, so there must be at least three cylinders.

Three cylinders are required. An engine with one cylinder is a motorcycle, or it may be a tractor, and a two-cylinder engine is also a motorcycle, and only a three-cylinder engine can be a car.

Although environmental protection is now vigorously advocated, we consumers are naturally prejudiced against three-cylinder engines, and car companies can't get along with themselves. Many models that have introduced three-cylinder engines have failed one by one and have had to switch back to traditional four-cylinder engines, so that sales can increase slightly. Six- and eight-cylinder engines are exclusive to performance cars and have little to do with shopping carts.

Conventional car engines basically don't have a single cylinder. If there were, it was decades ago, and the history of single-cylinder engines in the automotive industry was very short at the beginning.

At present, the automobile market is dominated by four-cylinder, six-cylinder, eight-steel, and twelve-cylinder engines, and more and more three-cylinder vehicles are gradually introduced due to emissions. So now the four-cylinder engine is still the mainstream, so the good thing asks, is there still a three-cylinder or less in the world? Examples include twin-cylinder engines and single-cylinder engines.

You can start by giving a conclusion: yes. But why not be popular?

That's because there are a lot of ills, and it's really hard to meet people's needs. Two-cylinder enginesWe all know that many people don't like three-cylinder engines because of shaking.

In fact, many people may not know that a two-cylinder engine shakes more than a three-cylinder engine. According to the consistency of the direction of movement of the piston, the twin-cylinder engine is divided into synchronous asynchronous twin-cylinder engine. But no matter what the structure, it is difficult to counteract the imbalance caused by the left turn of the two pistons, which is a devastating blow to driving comfort.

Most of our common motorcycles, fuel mopeds, and tractors have a single-cylinder engine layout. Tractors do not have high requirements for power, sufficient torque and the characteristics of diesel engines, which can be met by ordinary single-cylinder engines.

At present, motorcycles are still more single-cylinder and have low cost. Some high-performance motorcycles can also use two or even four cylinders. The large displacement is not only powerful, but also the maintenance cost is much higher.

Can you see a single-cylinder engine? There is no doubt that in the countryside in autumn, farmers and uncles use tractors to transport bags of rice from the fields to the shore. Single-cylinder engineThe single-cylinder engine gives us the impression that it is loud, runs poorly, and feels rough.

For a single-cylinder engine, this vibration is irrepressible, and people who like to ride motorcycles should know these feelings best.

Now the cars on the market are based on four-cylinder buried ears, six-bend cylinders, eight-steel and twelve-cylinder engines, and these cylinders are very practical, and can also improve the service life of the car, and can also make the car dynamic Zheng force stronger.

At least two cylinders are needed, ordinary motorcycles or tractors are generally built on a cylinder, so the sense of vibration is relatively strong during driving, and there will also be a sudden sound of abruptness.

The engine needs at least one cylinder, which can ensure the power of the engine, and can also be reasonably arranged, so it is necessary to have a cylinder.

The number of cylinders in an average car engine is usually about 3 to 8 cylinders.

It is possible that the Israeli hybrid single-cylinder engine will be installed. This machine is mainly used as a range extender, and the structure of combustion work is relatively special, and it is not the inlet and burst exhaust structure of the piston connecting rod crankshaft of a traditional internal combustion engine. Instead, the transverse cylinder block and the two-way fixed piston reciprocate, and the horsepower of the machine is actually very small; It will be very inefficient to use for drives, but it can be a good option to send it to it.

This is similar to the research of electromagnetic range extender by a domestic new energy vehicle giant, and it remains to be seen how effective it will be.

Automobile engine needs at least three cylinders, otherwise the power is insufficient, the single-cylinder engine is generally used as a generator, and the single-cylinder engine is not suitable for use in automobiles due to loud noise and vibration.

Cars now need to start with a minimum of three cylinders, and most of the engines on the market today are 4 and 6 cylinders. There is no one-cylinder engine.

Car engines need at least three cylinders, one-cylinder engines do exist, and tractors in the countryside are one-cylinder engines.

Today, gasoline engines that meet the requirements of automobiles are at least three cylinders. The engine of the car you see running on the road every day does not have a 1-cylinder, and the engine with 1 cylinder cannot meet the requirements of the car.

1. Explain the reason to you.

If you want the car to run at a certain speed, it must require that its heart engine must have enough output power, and the production model takes into account the cost problem and wants to increase the power, usually by increasing the displacement. Under the same power requirement, the more cylinders there are, the smaller the cylinder diameter can be, and the higher the rotational speed. The number of cylinders increases, the average effective pressure increases linearly, the engine length increases, and the balance improves.

Therefore, in order to improve the engine power, manufacturers will increase the number of cylinders, and now there are at least 3 cylinders for cars.

Second, in fact, there are many single-cylinder engines.

In the last century, single-cylinder diesel engines were used in agriculture that were too widespread. Single-cylinder tractor, that is simply a god-like existence, don't look at it small, but the horsepower is not small, pull.

Three, two tons is no problem. There is no problem in climbing and descending the river. Single-cylinder diesel generators, single-cylinder diesel pumps, etc., these single-cylinder diesel engines can be seen everywhere. Fuel economy and high horsepower are its advantages. The disadvantages are: loud noise, sharp jitter.

3. Single-cylinder engines are also widely used in motorcycles. Due to the application on motorcycles, the engine is required to be small in size and sufficient in power. So the engine of a motorcycle is mostly a single-cylinder engine.

One of the drawbacks of a single-cylinder engine is that it shakes a lot. Because most of the engines are four-strokes. The process by which a cylinder does work is:

Inhale, compress, do work, exhaust. To put it simply, every two revolutions of the engine, the oil in the cylinder is burned to do work. That is to say, one and three-quarters of a turn of the engine is not work, and the work of the engine is consumed.

As a result, the engine runs very unevenly.

If it is a four-cylinder engine, then each stroke of the engine, there is a cylinder doing the work, and the engine runs much more smoothly. If it is an eight-cylinder engine, there are two engines per stroke on average, and the engine runs very smoothly, so most high-end cars will use 6-cylinder and 8-cylinder engines.

One-cylinder engines existed in the earliest days. However, most of today's cars have 4-cylinder engines, which can provide stable performance.

The engine needs at least three cylinders to run stably, and a one-cylinder engine does exist, as was the case with the first-generation Mercedes-Benz.

A car engine requires at least three cylinders, but one cylinder does exist, such as a tractor.
