How many cylinders do you need at least for a car engine? Do one cylinder engines exist?

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.

Summary. Hello, this question can give you a perfect reply, wait for me to sort out the information, I'm typing, 2-3 minutes, don't finish.

Hello, this question can give you a perfect reply, wait for me to sort out the information, I'm typing, 2-3 minutes, don't finish.

Good. Hello, I am your exclusive elite technician, we promise to be attentive, careful, and attentive to answer your car questions. Hello, the engine 4 cylinders have a certain morning and a cylinder does not work, and then go on the road to tremble and drive 100 kilometers, this will not affect the life of the engine, there must be a cylinder, Lu Dong stares does not work His impact is mainly high fuel consumption, the second is that his vehicle is not powered enough.

It will not affect any part of the engine to be damaged.

Thank you. Just finished the maintenance, cleaned the engine, and went back to the road shaking.

Hello clear engine shake, this must be the spark plug where water has entered, take the spark plug out and dry it.

I checked it and said that the screws of another cylinder were not tightened, and this cylinder was not working.

If it's not a big problem, you can re-tighten it.

The lack of a cylinder salary is also shaky.

Job. Definitely, if there is a lack of a cylinder to work, it will definitely be very proactive.

Shake. Ask about custom messages].

The first cylinder of the engine is specified as follows: the first cylinder in the direction of the pulley shall prevail.

The cylinder is the cavity where the piston is placed on the cylinder block of the internal combustion engine, which is the track of piston movement, which is composed of cylinder barrel, end cover, piston, piston rod and seal. The gas burns and expands in it, allowing the engine to function properly.

If the cylinder volume is too large, the piston weight will increase, the combustion rate will decrease, and ultimately the smooth output of work will be affected. Because the crankshaft of a single-cylinder engine burns only once every two rotations, the operation is very uneven, and later by increasing the number of cylinders, a small amount of combustion is sequentially burned to make the operation more uniform.

Away from the gearbox side, start counting, and in front of the line is the first cylinder. In other words, the first cylinder is in the direction of the pulley.

In the case of an in-line engine, count from the side away from the gearbox, with the first cylinder in front.

In the case of a V-engine, the engine is divided into two cylinder rows, the left and right cylinders, usually the first on the left as the first cylinder, from the side away from the gearbox as the front of the engine!

W-type and horizontally opposed engines are distinguished by the number of cylinders in the V-type engine to distinguish the first cylinder!

There is no rule, that is, the cylinder at the front of the engine is the first cylinder, and it is called that.

The first cylinder is in the direction of the pulley.

Car engines.

A minimum of three cylinders is required, and there is no one-cylinder engine. Most conventional car engines have an intake valve and an exhaust valve for each cylinder. This type of double cylinder crank linkage mechanism.

It is relatively simple, low cost and easy to maintain. For general automobile engines with relatively low power requirements, two cylinders will obtain satisfactory engine output power and torque characteristics, and high-horsepower engines require multi-valve technology.

The simple multi-cylinder theory is a three-cylinder construction, where a two-cylinder with one row adds an intake valve to the structure. In recent years, most of the cars developed by automobile companies around the world have adopted four-cylinder structures. In a four-cylinder valve train, each cylinder has two intake valves and two exhaust valves.

The four-cylinder construction further improves the efficiency of the engine's intake and exhaust ducts. Most new cars use four-valve technology. Naturally, everyone mainly uses five-cylinder technology, such as the 20V engine of the old Jetta King, the 5-cylinder Bora diesel engine.

However, when the total number of cylinders is 6 or less, not only is the cylinder distribution structure too complicated, but the engine life is also reduced, and the total area of the curtain (cylinder circumference and valve lift) during the opening time of the cylinder is also small, thus reducing high efficiency. Therefore, the four-valve theory is the most commonly used technique today. If you want to compare the total number of cylinders, their advantages and disadvantages, first determine a fixed specification, for example, under the same displacement, the same technical strength, and then compare, the liter of the four-cylinder engine and the liter of the V8 car engine are not comparable, completely incomparable, so we must pay attention to this, do not have to try to study in detail.

It does the power stroke superposition effect, a circulation system for the four-stroke engine in the car today.

It's 720 degrees, which is a propeller shaft.

A process of 2 turns or reciprocating motion. If the engine of a car has four cylinders, the four cylinders are replaced by ignition, and the other cylinder is gradually ignited immediately after one cylinder is ignited. If the number of cylinders in the engine is even 12, it is easy to accumulate the power stroke.

The advantage of the accumulation of power strokes is that when one cylinder has not finished ignition, the other cylinder now starts to fire the knotting force, and the driving force is uninterrupted. Therefore, compared to the four-cylinder engine, the ride ride of the six-cylinder engine is a qualitative change.

Generally, a car must have at least three cylinders and a one-cylinder engine, such as motorcycles and tractors.

A minimum of three cylinders is required. Now there is no more, and the one-cylinder engine cannot meet the driving requirements of the car.

At least one is needed; Without a one-cylinder engine, at least three.
