This is the BMW N52 engine block. It is made from a combination of magnesium and aluminum. It has an aluminum inner block witch contains the cylinders, water cooling and the main bearings, and the outer shell made of magnesium.
They have improved the process. Used to cast thy he cylinder wall as a single solid block and drop in in a mould then inject mold the magnesium casing around it with the R1 magnesium alloy.
I like my N54 VANOS twin turbo, now that they have the proper injectors and high pressure pump [post recall] it has been flawless. I hear the quad diesel W57C30T1 is a beast
calizess lol no they also have tons of recalls and so many parts that break before the warranty ends. No one keeps a bmw they bought new after the warranty ends.
So now the engine blocks are made of aluminium? All this time i thought they were made out of cast iron, i cant believe how the aluminium can withstand that amount of heat that the engine is producing
Aluminium is a way better heat transporter than iron and it's not twisting itself like steel engines do. If you look into your PC, there is an Aluminium CPU cooler, no Copper. Aluminium is a great heat trap, so ideal for engines.
@@Spelter good answer . but I have another question about the sand mold how could it withstand the heat and still keep shape after the alum block been taken off the sand mold.what is the secret behind it ?
@@peterlonter9053 I know it's a year later, but I worked in a foundry briefly and it's one of my favorite things to talk about. These sand molds use resin sand, which is sand mixed with glue, essentially. Sand has a higher melting point than aluminum, so it doesn't get destroyed during the pouring. The resin just smokes off. They don't save the sand in-between castings. The sand is probably shaken or blown off somewhere in this process. A new sand mold is made for each engine.
@@rsbatcrh06 At the first glance I thought it was some kind of deburring process, but surface coating makes more sense. Teaching the robot performing this process had a o be pain in the back.
@@mil3k it's similar enough to painting. Making sure the right overlap is key. Making sure the entire part gets costed eventually, in all those small hard to reach areas, now that's the PITA programing nightmare.
Hvof stands for high velocity oxygen fuel its thermal spraying you spray molten metal onto the block and it prevents wear and tear it will be machined back to leave a thin layer incredibly loud process but looks cool.
Wait the engine blocks aren’t made out of plastic too. Because I know everything else is. If your buying a bmw you don’t look for rust you look for dry rot.
The jobs given to the robotic arms would be dangerous for a human operator. Lifting a 500 degree casting that weighs 100 pounds over and over and over all day would ruin a person, then the company would have to pay your workmans comp and possibly a settlement. It's just way better to have robots. They do break down and need repairs a lot so there are still jobs we can do that they need to operate.
@@rq9924 well it was, and that's the problem. It's cheaper to buy robots than have some guy ruin himself doing that job. Safety is paramount, and if we can automate dangerous jobs, less people get hurt and those costs aren't passed onto the consumer. Your point is escaping me, I don't see why you would risk a human life over a minimum wage position.
BMW has the I3 model currently available. BMW has invested a few dollars into R&D with 12 new EV models built and manufactured by 2025. This only BMW engine foundry department lol
The most unreliable motors ever ! All BMW motors have oil leaking problems or pistones problems . Etc ..even for low mileage ! Old BMWs motors were much more reliable than today's ones !
