How Engines are made? (Mega Factories Video)

An engine is a machine designed to convert one or more forms of energy into mechanical energy. Mechanical heat engines convert heat into work via various thermodynamic processes.
The internal combustion engine is perhaps the most common example of a chemical heat engine, in which heat from the combustion of a fuel causes rapid pressurization of the gaseous combustion products in the combustion chamber, causing them to expand and drive a piston, which turns a crankshaft. Unlike internal combustion engines, a reaction engine (such as a jet engine) produces thrust by expelling reaction mass, in accordance with Newton's third law of motion.
An engine block on the other hand is the structure which contains the cylinders, and other parts, of an internal combustion engine. In an early automotive engine, the engine block consisted of just the cylinder block, to which a separate crankcase was attached. Modern engine blocks typically have the crankcase integrated with the cylinder block as a single component. Engine blocks often also include elements such as coolant passages and oil galleries.

Important use of robots, yes, but I'm surprised at how much of the work is still done by hand. I couldn't believe the guy tightening bolts with a torque wrench, and then making hand-written notes in a little book! Surely the construction of a cheaper, higher volume engine (for instance for a Corolla) must be a lot more automated...

[@xcranktc]

I think that what was shown here, were what are called "audit engines", where 1 out of say 100 engines is checked on manually. The normal assembly is likely indeed, a lot more automated.

[@acdii]

Not every engine is tested as it would take too long, they test random builds to ensure quality remains throughout production. The guy doing the torque at the end is doing a QC check to make sure that everything is being properly assembled, and again does it on random engines, not every engine. What is missing are the machines that do break in procedures prior to final engine assembly. This is usually done after the heads and timing components are fully assembled but before the covers are installed.

[@palithadias7081]

I am very much impressed by seeing engine block is made and testing.

[@MrTooTechnical]

Kick ass. The cylinder machining cross hatch was the best part. Thanks.

[@deaddoll1361]

You failed to mention the aluminium used for casting is an alloy containing copper, silicon, manganese and magnesium to make the material much harder than pure aluminium would be. Pure aluminium is soft and unsuitable for engine components and the alloy used contains 10% to 15% additives. This is true for the cylinder heads and pistons as well. These additives are clumped together in the material, however the alloy is heat sensitive and a severe overheat results in the hardening elements dissipating, resulting in a softening of the material. The cylinder head may be too soft to clamp the head gasket adequately and the clyinder head retaining bolts can lose tension due to the alloy they seat on slowly collapsing.

[@rexmyers991]

I was disappointed that the machining processes on the engine block casting (other than honing the cylinder walls) was entirely omitted. Close up shots of the block showed the mating surface of the head having been previously machined as well as the fuel pump mounting, etc. But, we did not get to see it.

I still can't get my head around not only what these machines are programmed to produce but the fact that people were genius enough to make the machines that produce the product in the first place. Truly amazing.👍

Actually to torque bolts by hand is the best way. But of course very time consuming. The person can keep a close eye on the tolerances. Porsche, Ferrari all the expensive engines are hand built for that purpose.

[@johnfranklin5277]

I have a 1968 Mustang coupe that was sold new in December of 67. Lifelong Southern California car bought at palm springs ford..289 , factory AC. Automatic transmission, power steering, and 4 wheel MANUAL brakes! LOL. White vinyl top. Has the cool turn signal lights in the hood. I bought it in 1977, my last year of high school. Was in great shape, I paid 600 dollars for it. Which of course was alot more money then than now. Is in excellent condition, still on the road. The original engine, only thing done to it was a new timing chain in 1982. My car was built at the SAN JOSE plant. Was 9 years old when I got it, now she's coming soon to 55 years old! Fortunately, I decided to stay 18...........I also have my parents 58 cadillac they bought in 1960. Its still on the road too.

Ones that don’t break all engines that are made today are junk they don’t last of course that’s all by design that’s how manufacturers get rich because they know that the engine will break after the warranty is up I like the engines from when they originated up through the 90s because they were built to last and they didn’t require a considerable amount of maintenance like these new ones do these new engines are very sensitive just like the people that are on the far left any little thing and they have a breakdown
