Behind every bumper cover is an impact absorber; a crushable structure designed to take a hit. Made of foam or engineered plastic, it compresses on impact to absorb energy and protect the frame. It’s a one-time safety feature though. Once it's deformed it can’t spring back which…

The bumper impact absorber is the hidden layer of protection behind every bumper cover. In a collision, it crushes to absorb energy instead of sending the force straight into the frame ,but it’s a one-time use. Once it's compressed, it has to be replaced. Follow the link to…

Every cylinder fire starts with the ignition coil. By stepping up battery voltage into a massive spark, it gives the spark plug the energy it needs to ignite the air-fuel mix and drive the piston down. Follow the link to learn more about casted auto parts like this:…

Did you know that ignition coils are basically mini transformers? These are critical for generating enough voltage to send to a spark plug to ignite the air-fuel mixture, pushing a cylinder down in the engine. Follow the link to learn more about casted auto parts like this:…

Every drop of fuel entering an engine passes through a fuel injector. These small valves open and close thousands of times per minute, spraying fuel in a precise mist that blends with air for combustion. When that spray is consistent the engine run smoothly, efficiently, and with…

Fuel injectors are precision nozzles that feed your engine with (you guessed it) fuel. By spraying fuel in a fine, controlled mist, they create a mix with air for combustion. This refined balance is what makes modern engines more efficient and reduce emissions. Follow the link…

The throttle body in a car decides how much air your engine takes in. Inside is a butterfly valve that pivots with every press of the pedal. When it's working normally, airflow is steady and combustion stays balanced, but if carbon builds or something happens to the actuating…

The throttle body in a car controls how much air enters with every press of the pedal. A clean, responsive valve means smooth airflow and balanced combustion, but when carbon builds up or the valve sticks, the engine can respond poorly with hesitation, rough idle, and possibly…

Continuing our week of data storage CT scans! Floppy disks were once ubiquitous; now they live on only as the familiar "save" icon. First released in 1971, these evolved from 8" to 5¼" to 3½" formats and could store up to 1.44MB of data. Let's look inside... 🧵

Over the past few decades, computer data has been stored on magnetic film, optical layers, glass platters, and silicon. Every day this week we’ll use @lumafield CT scans to look inside iconic storage formats, see how they work, and watch them evolve into what we use today 🧵
