Making a 2.4cc Petrol (Gasoline) Engine

Thank you for watching :)

I hope you enjoy this as much as I do!

I think a lot of people that don't know machining or engineering wouldn't have any idea how much effort it takes to make something like this. Especially with how amazing it ran! They always say you can tell just how good a motor is by how it sounds and how smooth it runs... And usually engines on the smaller side (especially 4-stroke) can be a little finicky. When I was in my junior year of tech school i made a single cylinder pneumatic motor that had a small generator rigged up to it, I wired it to a small maglite light bulb and that was about it. It took a good bit of machining and I had to get the tolerances pretty tight but it was an awesome project! It's almost 30 years old into this day you can still start it right up and it purrs like a kitten! Even the original maglite bulb still works

now that's a 1 cylinder, 6.6 microliters, 120 mousepower engine that goes from 0 to 60 feet/h in under 3.5 seconds

No talking, no music. Just awesome stuff being done.

This was insanely cool! I've been a machinist for many years and this takes it to a whole new level! You could sell this as a DIY kit and I would buy one. Very cool and Good Job!

if only youtube had Oscars, the award for content creation would go to this guy.

I'm a Civil Engineer, but this video made me respect the mechanical engineers, even more.

salute to you sir.

No words, no music, just work. Excellent! Without this “when I was child, I saw an ice engine and..”

I love how he didn't explain anything verbally and that there wasn't any background music. Just the sound of the machines sublime!

I spent my youth and early adult years competing in racing control-line model airplanes that had 2.5 cc engines. (FAI Class F2C - Team Race) There were many aspects of the sport/hobby that were required in order to be successful, from a light but strong model, to a high performing quality motor. As nothing competitive was available off the shelf at hobby stores, everything was hand made, from the model, to in some cases the motors itself. We had a highly skilled machinist who for several years made the motors from scratch, while in other years we relied on motor specialists who had mini mass production runs, and made their motors available for sale to some competitors. Motor technology was continuously refined and performance improved and the motors became more capable.
My brothers and I raced planes with diesel (compression ignition) two stroke motors that had to fly in 100-lap qualifying heats, and 200-lap finals. There were strict limitations on plane dimensions, including fuel tank size. Essentially our plane had to fly at about 125+ mph for at least 33-laps on 7-cc of fuel, then make a pit-stop to refuel. A really good 100-lap heat race time including two pit stops is in the low 3-minute range.
A successful racing engine is all about metallurgy and precise tolerances. We bought some Russian-made motors which were consistently winning at the time, and our machinist couldn't figure out how they made the pistons, which are critical to success. It appeared to be some sort of sintered blend of aluminum that was high in silicon. As our racing motors were always run lean to get the most range, they ran very hot, so the science behind pistons was in how to control thermal expansion at high temperatures so the engines didn't seize while running hot, yet expanded at the same rate as the cooler cylinder to maintain compression, while being hard enough to show little wear after many races running with low percentages of lubricant in the fuel. Cylinders were typically chrome-coated and had a very slight taper so that when pistons were lapped to fit they were 'tight' at the top of compression, yet ran 'a little loose' through the rest of the bore to minimize friction.
We had to learn a lot about everything from aerodynamics; construction and design techniques; materials science; combustion and fuel science; to competition strategy. We were lucky to receive 'free samples' of new high-strength materials, such as just developed Kevlar and Carbon fibre, from companies like Dupont, and fuel additives from Shell, who were willing to support our efforts. We we lucky enough to qualify on the Canadian team about 6 times to compete at the FAI Control-Line World Championships in Europe in the 1970's, 80's and 90's. It was a great learning experience and an opportunity to travel and represent our country in a highly competitive and technical event.
A quick search on YouTube of - FAI Class F2C - Team Race - will show what the racing is about.

Very impressed. No matter what, you'll always have that little engine as a reminder of your skill. Great job man!

[Chevymacjr]

If I may ask, how great did it feel after 1000 hours of design and building to hear that engine start successfully? This was beautifully done and well executed. Nice work sir!

[juniorgaitho]

On behalf of all engine heads, thank you for this awesome video and thank you for your creativity. God bless 🙌

[rikusvolschenk]

This is like watching an artist work sir! The perfect machining, to the exact tolerances required, to create such a small scale working engine. Mind blown...

[TastySurrealBowl]

When you first began to turn it over I realized I had actually slid forward and was literally sitting on the edge of my seat. When it started I actually cheered out loud. Fantastic work!! 🏆

[ogdennash]

Fantastic planning, design and manufacturing skills - well done.
I started my apprenticeship in 1978 and you brought memories flooding back when you used the Engineers Blue for marking out - I had forgotten that stuff !
Great job !

[Tuppose]

This really blew my mind away. Amazing application of engineering, design & craftmanship. Making stuff at this scaly requires some scary pinpoint accuracy. Super cool !!

[Sment]

I've watched this and now I'm trying lift my jaw from ground. So much precision, so much skills, so elegance, so perfection, so magnificence. Great job bro.

[pjhalchemy]

I've seen quite a lot of miniature engines including some radials up close and personal. Made by guys/gals that have an arsenal of machines to fabricate them, But I have to say the precision and accuracy, let a lone the design, that you've done with a Sherline is the most impressive build I've seen in my old age. I enjoyed the build videos but this compilations is an inspiration in machining and videography! Thanks very Much for the ride and hope you continue to test yourself with projects like these!! Hat Tip ~PJ

[StuffMadeHere]

Excellent work. It looks like the piston gained an o-ring by the time you assembled it ;) What type of o-ring is that? Does it hold up?

[stephenbridges]

All a person can say is, "Wow!". You are a very talented machinist.

[GT-dhnk]

There's a joy in my heart I can't describe with words when I see someone do something like this for the sake of doing it.
