A passion for engineering talked by a man who made the world's smallest V 12 cylinder engine

It has a clear sound with uniformly spaced explosions and low vibration, previously used in F1 machinesV type 12 cylinder engineIsIdeal engine layoutIt is said to be one of them. On the other hand, although it is a handy V12 cylinder engine to require high precision and quality control of parts, it is known that a man in Spain reproduces its own V12 cylinder engine that can be called "palm size" It is talking about a hot feeling for engineering.

El motor V - 12 más pequeño del mundo. (Smallest V - 12 engine of the world)


Camshaft that is only as big as the palm of your hand.


The piston, the most important part of the engine, is only as big as the fingertip.


The length of the crankshaft which rotates inside the engine is about 15 cm.


Parts lined up in a row.


Started assembly. That work is very precise.


The bolt that tightens the cap of the connecting rod needs to use tweezers.


This engine drives a valve through a rodOHVAdoption method. Push rods extending from the crankcase to the cylinder head are only as big as a toothpick.


It is said that tightening with a small hexagon bolt is around the exhaust pipe for exhaust.


If you install a cylindrical silencer ......


Completion of world's smallest V type 12 cylinder engine.


Of course the flywheel attached to the crankshaft is also reproduced. The main body is made of stainless steel, aluminum, bronze (bronze), all parts excluding bolts are made by cutting out.


It is worth seeing that the rocker arm of about 1 cm in length accurately scores the rhythm. This engine is driven by compressed air fed from the hose.


The inner diameter and stroke of the cylinder are 11.3 × 10 mm,Bore stroke ratioIs less than 10.88Short stroke type. This is smaller than about 0.93 of Nissan GT-R, and FerrariF12 BerlinettaIt is close to the value of 0.8.


José Manuel Hermo Barreiro, "Patelo" living in Spain, has created a miniature V 12 cylinder engine that is unimaginable. Barreiro who worked on creating this engine to shape passion for engineering talks about his passion from the following movie.

The man behind the smallest V-12 engine in the world (English subtitles)


Barreiro says, "Each piece I make is like my child." Previously I was in charge of duties as a naval engineer.


The engines that Barreiro has created are listed next. A number of works that have been built over 15,000 hours of effort.


The total number of engines we have created so far is eleven. Barreiro points out "This is the newest thing."


The latest work is seen as a star-shaped double-row 10-cylinder engine used for airplanes. It seems that the number of parts is 660 pieces.


More special W 16 cylinder engine. It is regarded as a type of two V8 engines side by side.


"If you can successfully use it, it will be an enormously powerful engine," Barreiro says.


This is an engine for ships. It seems to be an engine of the type that two engines are connected and take out output from the middle.


And this is the "world's smallest" V12 engine that appeared in the movie above.


"I do not know because I do not see the Internet, but I have never seen anyone who made something like this," Barreiro says with a smile.


The time required for production was 1200 hours. "I wish I could use it at school etc." I am talking about its aim.


To the photographer, Barreiro talks of surprise, "I did not think that people like you came visiting me or that this engine would be known around the world."


"Lend me a coin," Barreiro puts a coin on top of the moving engine, but surprisingly the coin will not be a tremor, rather than collapsing. In theory, it is known that the vibration generated by rotation is known to be zero in a properly constructed V12 cylinder engine, but it is surprising that it is reproduced with this size.


Barreiro says the ocean is involved from childhood. It is around 5 years old, but at 2 am on a weathery day, on a favorite boat, the city in the northwestern part of SpainA CoruñaSailed, he said he encountered Blizzard.


I do not understand the phone and it seems that the fact that everyone thought that they were "distressed" and had a terrible feeling was the reason for having a connection with the ocean.


When making an engine, Barreiro says that it starts making from camshafts and cylinder blocks. Based on those, they are going to build parts one by one and assemble them, he says that way "to build a trump house".


"Because if you make one you want to see where it is moving"


"But when that is the beginning of the problem, when it does not go well, we have to do something even though we have a hard feeling, so we have a satisfying feeling when we completed it," he talks about his passion for production.


For example, it takes 4 to 5 hours even for the time to make a small camshaft. Set the bar as the material on the lathe, sharpen it with fine work and gradually bring it closer to the finished shape ......


Then polish further to finish the details. It took 30 hours to complete this work alone.


"Even though I make something, now few people can do it myself"


Barreiro worried about the loss of engineering, "We purchased everything made at the factory and the mechanics just replace it." Even in Japan, it means "an engineer who just needs to replace parts"Change niaAs the word "born" is born, there seems to be a flow of concern for similar things in the world.


"Everyone buys parts and exchanges it, I do not mind things like" Why has it broken? "


Barreiro says "The engine is like my son for me, I truly think so," he talks about his passion for machine.


Barreiro reminds me of the past while visiting the ruined building on the beach. "I started working here when I was sixteen, where there was a factory, and when mechanics were born one after another, they grew up."


"Everyone was a young man about 13 to 20. 90% of the dreams I have are still related to the ship even now."


"What I'm still dreaming is to design an engine room of a huge ship that crosses the Atlantic Ocean."


"Four engines are tied in a transmission ... ... turning two variable-pitch screws attached to the propeller shaft and going out to voyage ... but, I am 72 years old, maybe it is already already late There is not it. "


I would like to see Barreiro's passion whereabouts if possible. Other than this, the engine by Barreiro was introduced on the following YouTube channel.
