Distinguishing types of car engines – Not everyone knows
Hello friends and friends, the engine is still considered the most important detail on a car, even a motorbike, so it is considered the soul and the heart of a car, not everyone knows it. Advantages and disadvantages of each type of engine that we often encounter such as I1, I1, V1, V1 and so on today we will learn about this issue.
The first type of engine is also the engine we often encounter, the I4 engine, this engine has a fairly simple structure with 1 row of cylinders arranged in a straight line with 1 engine cover and 1 main row of rubber because of the That simplicity should be chosen by many manufacturers, with many opinions that I1 engines are not capable of producing as much power as engines with many cylinders. Actually that is also a correct opinion, but it is not entirely true, in fact, manufacturers equip I4 engines with some equipment such as turbochargers from which they are about to produce I1 engine power, it will be very It's even bigger than multi-cylinder V4 or V1 engines. Of course, it's rare, not too many of us, we don't often come across engines with too much turbocharger on the street, mostly still I4 engines, about the pros and cons, not everyone knows us. try listing.
In terms of advantages, the first is the compact design, the structure is very simple, the design and structure is simple, so it is very suitable for many models from popular to high-end, a lot of different design drills. Ideal for installing engines on most vehicles. (Which type of gasoline and diesel engine is better? Detailed comparison of gasoline engine & diesel engine).
Second, about the lightweight I4 engine, we only have 1 exhaust, so the fuel economy is usually very good, adding an advantage on the I1 engine, we have a better ability to keep the energy consumed. Compared to multi-cylinder engines because it has fewer moving parts, it only has 4 engine block, so its energy loss will be lower than that of multi-cylinder engines and another very important advantage is that On the i1 engine, it is because of the simple and compact design that there are many manufacturers to choose because of the cost-effectiveness of production, this cost-saving feature directly affects the price of the engine. car. You notice when we use the I1 engine it is usually very reasonably priced compared to the engine like the v1, V4, I4 and so on, the I12 engine its car prices will usually be lower and it approaches the masses. Most consumers, besides those advantages, we still have some disadvantages on the I8 engine.
The first disadvantage that is mentioned is often I4 engines we will encounter limited cylinder capacity of 1.5, 2.0 2.5, 2.7 if above 3.0 very few I4 engines can do it. cylinder volume in this engine. The downside on I4 engines is that the center of gravity of the machine is set high, so it is not suitable for sports cars, high-performance cars need a lot of compression down the road to minimize these things and still keep the dynamic. I4 engines on such vehicles many manufacturers lower the engine to optimize the vehicle's center of gravity and the final disadvantage is that the I4 will often not be as stable and quiet as V-shaped engines or engines. many cylinders by the forces generated by the action of the piston acting on the shaft of the I4 engine, it is uneven and easy to cause vibrations for the user. To limit this, many manufacturers equip a balance shaft above the drill to help the car operate more smoothly, stably and from the middle, why many manufacturers or consumers believe in using I4 engines. Thus, we have a flexible, fuel-efficient engine at a reasonable price and high compatibility with many car models, so the i4 engine is always the golden choice for car manufacturers.
The second type of engine, we have an I2 engine, an I6 engine we don't see much on the road compared to an I6 engine mainly on luxury cars such as BMW or Mercedes Benz If I remember correctly, the Mercedes Benz X6 also just launched in Vietnam also uses an I6 engine, it produces a capacity of 320 horsepower, which is very powerful and the I6 engine is also an engine, so the structure is also 1. The row of cylinders is arranged in a straight line compared to the I1 engine, the I4 engine is larger than 6 cylinders, the biggest advantage of the I2 engine is the ability to operate very strong due to the detonation order of its cylinders. is rearranged more optimally compared to the I6 engine, as well as the I4 engine, the production cost of the I4 engine is also good, and the ability to receive fuel is also optimized.
The I6 engine also has some disadvantages such as a high center of gravity like the I4 engine, the second is that the I2 engine is less selective because with the design of 6 more cylinders it will be longer than the I2 engine, so i4 engine it will not be suitable for front-wheel drive vehicles. From the middle of the i6 engine, we have to emphasize in a few strong points the ability to save fuel, optimize production costs, but it is very difficult to choose a car, not all cars are equipped with this type of engine.
Talking about the third engine that is not easy to see is the V-engine, as you know if the i-engine is arranged in a configuration, the cylinders are arranged in a straight line, the V-engine has 3 rows of cylinders. so the structure is V-shaped, the engines we know are the V2 V6 V8 or V10 engines, the V-shaped engine has a crankshaft structure, it will be more complicated than the conventional engine.I
Some of the advantages that I want to tell you about in a V-engine are that its design is very solid, it is optimal for both front- and rear-wheel vehicles, it is not too bad to choose the vehicle that you are equipped with. .
The second is a V-engine that has the ability to increase the cylinder capacity as you notice V2 V1 has cylinders of 6, 8 3.0 or 4.0 V4.9 types, the ability to expand the surrounding capacity as well. It's also an advantage worth mentioning, in addition to the v-engine is a very powerful engine, you often see engines like V6.0 on sports cars like Porsche or land Rover 8 SUV in addition on the market. V-engine has a squarer structure than an in-line engine, so it limits the centrifugal force when the car turns at high speed.
In addition, the V-shaped engine allows the gravity to be evenly distributed to both sides to reduce vibrations during piston operation, besides the advantages that V-shaped engines have many disadvantages such as production costs. high because there are 2 engine covers with more details than the i-engine.
Second, the cost of use is also high due to the weight of the machine, it is heavy, the center of gravity is high and many parts are heavier than i-engines and with many moving parts, the V-engine will lose kinetic energy due to friction. and the size of the engines is also large, although it will be suitable for vehicles with front or rear axle sizes, but that size limits the size of the car, for example a V-engine will be suitable. Compared with big, bulky cars on the V-engine, it operates stronger, more durable and it is stable, besides, it also has some disadvantages such as high cost, production high, it's bulky, not all vehicles can be equipped.
The fourth type of engine, less common is the boxer engine, about this engine structure can be like this, for example, an I-shaped engine will have a single row of cylinders designed in a straight line with 4 stroke. with V-engines are 1 i-engines coupled into a V-shape, with Boxer engines, the cylinders are symmetrical, this type of engine is very suitable for sports cars and high-performance cars such as Cars with high performance typical of boxer engines such as Subaru or Porsche 1 these brands are maintaining the Boxer engine in their cars, why are these two big car manufacturers using Boxer engines to equip them? on his car.
Firstly, the Boxer engine has a very good and powerful operating ability, secondly, the balance of the Boxer engine is smooth because the cylinder structure is horizontally symmetrical, so the primary and secondary forces It shines on both sides more when bouncing into the cockpit, making the car more stable and smooth, and so on.
Next, on the boxer engine we have Brixtons located close to the bottom so that the center of gravity will be lower and it is more optimal for sports cars that require large acceleration. Besides the advantages are the disadvantages.
The disadvantage of the first Boxer is the complexity of production, the production cost is already high, but the complexity of repair if the I- or V-engine is normal, the vast majority of private garages are owned by them. can be intervened but for Boxer engines, it will be very difficult to repair by yourself, usually take it to the company because this engine if repaired, you have to disassemble the engines and the internal details are also complicated. so repairing this Boxer engine is not easy.
The second disadvantage is that the cylinders are horizontal and symmetrical with each other, so the area and width of the boxer engine is higher than that of the V- or I-shaped engine, so it is designed with the engine compartment. It is necessary to optimize this engine, it takes up more horizontal area and because of that, the production cost of the engine is not cheap and it directly affects the selling price of the car, also because of the low cost. Horizontal engine element it will generate more wind resistance than engines placed vertically or squarely in the center position, from the middle from the Boxer engine we have the ability to operate strongly, smoothly. very good, besides there are some maintenance difficulties or high costs, so the Boxer engine is only suitable for sports cars, high performance cars and great acceleration.
The fifth engine is, the W engine is actually this engine that is rarely seen on the street but will be encountered on expensive cars like Bentley or Bugatti supercars or supercars in the world, the W engine is like two word engines. V clustered together to form the letter W and the engine size is very large, the W engine has many different types of cylinders such as W5, W2 with 12 cylinders also rare, there are 16 cylinders, it is very special if make no mistake, the W16 in the American Cadillac is terrible using the engine to 32 cylinders, its dot is somewhere 16 points and the advantage of the W engine is its ability to operate, capacity and efficiency. Big it is much more terrible, normally this engine only appears on supercars, the second is that the engine length is shorter than the V-engine but the width will be larger. (Update the theme 600 questions for the driving test Latest).
Next is the disadvantage, the W engine also has disadvantages such as consuming gasoline, its production cost is large, many complicated pistons, cylinders and things, from which the production cost is also very high. That is why there are expensive cars, usually W engines. There is a lot more engine noise than other engines because of course it is a big engine due to many pistons operating many cylinders. That's why engine noise is inevitable. But on super luxury cars they all have very modern soundproofing technology, so when sitting in the car, you can't hear the engine at all.
That is, there are 4 engines we often encounter on the street.
