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…

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 🧵
