DIESEL ENGINE AND Gasoline ENGINE – Advantages and disadvantages of each type and which engine to choose?
Hello everyone! Nice to see you again in my latest video today, in today's video clip, I would like to share with you about Diesel engines, how are gasoline engines different from each other?
First of all, let's talk about Diesel engines! What is the diesel engine like? Well here, you can observe the Diesel engine, here I have an illustration! There! do you see? How does this diesel engine work? The difference between a Diesel engine and a gasoline engine is the ignition system. Gasoline engines use spark plugs and Diesel engines use natural fuels... Diesel fuels spontaneously ignites at high pressure and temperature in the compression stroke of the engine, you can see that The Diesel engine has absolutely no i-vi, it only has a corn-soup system and a fuel injection system and that combustion zone is Diesel only. Then it also has four strokes, which are intake, throw, explosion, exhaust ... but in the Diesel engine, it compresses many times more than the gasoline engine, the Diesel engine has a compression ratio of about 15 to 25. 9, gasoline engines have compression ratios from about 13 to XNUMX.
Compression ratio is the ratio of the volume of the combustion zone during the intake stroke and the compression stroke, for example, the intake stroke is 10 liters and the compression stroke is reduced to one liter, then the compression ratio is 10.1 that is like that. Ladies and gentlemen, nothing at all. then because it requires the Diesel it has to burn when it is compressed at high pressure, so the compression ratio of the Diesel engine is very large, it also has a four-stroke operation, as you can observe, here it's a compression stroke!…that's… the piston goes to the top and compresses. Then at this stage when the cardboard comes up from the bottom, it compresses, it makes the mixture of gas and Diesel very high pressure and very high temperature, at such high temperature pressure, Diesel it ignites itself guys, self-igniting and it does work to push the piston down and the explosion period, this is the exhaust stroke, it also charges, compresses, explodes, exhausts just like a four-stroke gasoline engine. well, that's… you see.
Thus, the Diesel engine has a simpler structure than the gasoline engine, so it works less damaged and more detailed. It does not have a spark plug in the ignition system, so it works less often than the gasoline engine, the gasoline engine, here you see the engine. gasoline, then in the gasoline engine you see it has a spark plug, it's clearly in the middle and the middle, it also has four cycles of intake, compression, explosion, exhaust... But at the end of the compression stroke, the stroke begins. When it explodes, it starts the spark plug, it ignites, ignited, igniting the fuel mixture, including gasoline and air, it is mixed together and when it is ignited, the work of driving the piston down and it causes the crankshaft to rotate. the engine just spins, here I can rewind this part for you to see, here you see this very obvious spark plug, that… you see? That spark plug will use an electric spark to ignite the fuel mixture, push the work to push the piston down to create an explosion, and it's the same thing.
That… it also has four cycles of intake, compression, explosion, exhaust… here! You see this picture, this is a tree right at the crankshaft, then because the Diesel engine requires Diesel fuel, it requires a high compression ratio to explode by itself, so the Diesel engine with its longer crankshaft, ie the distance… this distance guys…. This distance, this distance! From the shaft of the crankshaft to the place where the arm is attached it's longer than the petrol engine, this distance ha! This distance is longer, the longer this distance is, the greater the compression ratio will be. At the same time in the detonation period when the piston it is pushed down by the fuel that burns the work.
Then this is like a lever arm of a lever, the longer this is, the greater the force of the engine, ie the larger the torque, ie the compression ratio is related to the torque, if the compression ratio is large. The torque is large, because the Diesel engine has a much larger ratio than the gasoline engine, so its torque is very large, ie the rotational force of its wheels is very strong. That's why the Diesel engine can work, starting at a low engine speed, it has a very large traction force, that's why Diesel engines are used in heavy machines, machines. giant machines such as trucks, ships, etc. vehicles that require a great deal of rotational force. It is for the same reason that the Diesel engine has a large mass and bulky size, so the Diesel engine is not suitable for mounting on small cars, small passenger cars or cars. motorbikes.

It is because of its large mass and huge size, and also because its compression ratio is very large, that the Diesel engine cannot have high speed, its speed, Its rpm is lower than that of a gasoline engine, its maximum speed on a passenger car is about 6 thousand on a passenger car, and on a gasoline engine, its maximum rpm can be up to 8 rpm. to 8000 or higher 10 rpm or higher than 12.000 thousand or 8000 rpm for motorbikes and passenger cars, it is also about XNUMX rpm. The petrol engine has a higher rpm, so it is more loaded in the third country, but its traction is lower. That is, when you run galenti, the gasoline level is low, it is easy to turn off the engine, while the diesel engine is stronger, it can overcome difficult terrain.
It is for these reasons that off-road vehicles use diesel engines, it is more appropriate, on passenger cars, car manufacturers often release 2-engine versions, the first engine is the engine. gasoline, the second engine is a diesel engine, the gasoline engine is for those who like smoothness and it picks up at the top and the diesel engine is for those who like to save fuel and it has great torque, can go offroad terrain well, because the price of diesel fuel it is significantly cheaper than gasoline, Diesel it is dio oil it is about 14 today, and gasoline it is about 18-19 thousand it seems today 20 thousands already, and the Diesel and the gasoline it is usually separated from 4 to 5 thousand, so using the Diesel engine is more economical, more cost-effective, in addition, the Diesel engine is more economical. The gasoline engine too guys, because the Diesel when 1 liter of Diesel burns gives more energy than 1 liter of gasoline burns.
It is for all these reasons that the power of the engine, the efficiency. The efficiency of the Diesel engine is about 1,5 times greater than that of the gasoline engine, and in terms of the level of the Diesel engine, it is also considered to be better than the gasoline engine, modern Diesel engine is more expensive than the diesel engine. gasoline guys, for example the Hi-Hendai-siussphia car with a diesel engine record, sorry I am talking about the Diesel engine it is more expensive than the gasoline engine, for example the Hihen- The diesel engine version is more expensive than the gasoline engine version of the company, a few tens to 100 million more ... that's... the current diesel engine has been improved a lot to reduce the noise level and reduce the degree. vibration and reduce the smell of oil when released, because the Diesel engine has a large compression ratio, so it causes consequences such as very large vibration and very loud noise. the one when discharged is not very clean and it has a bad smell,.
Therefore, people for whom appearance is important, when they go to diplomacy, people are afraid to ride a diesel engine, because it's too loud, its sound is too loud, and it doesn't work at all. That's why people don't like it, but in my opinion, I prefer diesel motorbikes, because I ride a diesel motorbike, it will be much more beneficial, especially if you go with pickup trucks or seven cars. where Ecvivi, those cars have a lot of weight, usually 1 ton 8 to 2 tons or more. Then, for such large cars, if you go with a gasoline engine, it is very expensive, very wasteful, for example, the Tozota Photino petrol engine version is about 15 liters of fuel synthesis.

As for the diesel engine, it's about 7 liters, those are the numbers that the company writes on the glass, I go to Tozota, I see, plus the gasoline and oil fuel stickers, it's clear that you're driving an SUV. If you go with a diesel engine, it's much more profitable, and the pickup trucks, you go with the Victim pickups, SUVs but you go with a petrol engine, you just have to determine that its fuel quantity is very good. is terrible. The gasoline engine and the diesel engine in summary, the only difference is that the ignition system is the only one, ie, the fuel oil engine it self-ignites, and for the gasoline engine, it needs spark plugs to ignition, only the basic difference is not much different, in terms of durability, the diesel engine is more durable than the gasoline engine, the gasoline engine has the advantage that the engine rpm is higher, so it runs mechanically. The engine is a little more powerful, while the diesel engine has a large torque, the large torque helps it to have a large wheel's traction, which can be applied to vehicles that need large traction such as trucks, cars works or bridges….vv…
Then each car it has its own advantages and disadvantages...that's... then choosing a certain engine is up to each person's preference, usually I don't mean to distinguish the region, usually people in the region The north often chooses the gasoline engine more than the people in the south, the people in the south are very pragmatic, which car is efficient and saves a lot of people run the diesel version a lot, that's also It's just the opinion I've observed, not the regional distinction here, if you were, what motive would you choose? Gasoline engine or diesel engine? Please feel free to comment below the video. OK! hello goodbye and see you in the next video, thank you for watching the clip. Bye bye…
