Explain Modern Fuel Injection Clearly

I’m preparing a piece for the general public that demystifies how a modern internal-combustion engine meters fuel. The goal is a technically correct but easily digestible explanation that walks a curious reader from the moment a driver presses the accelerator to the precise instant fuel sprays into the combustion chamber.

I’d like the narrative to touch on:
• Sensors and data flow to the ECU
• Differences between port and direct injection
• The injector’s construction, timing and atomisation process
• How pressure regulation and fuel rails interact with pump delivery
• The way the whole system balances power, efficiency and emissions

Keep terminology accurate, yet always define acronyms and avoid jargon where a plain-language equivalent exists. Visual aids are welcome—simple labelled diagrams or flow-charts can sit alongside the text—but the writing itself should stand on its own at roughly 1,000–1,200 words.

Cite reputable sources for any figures or technical claims, and deliver the final piece as an editable document (Word or Google Doc) plus separate image files for any graphics.
