@explainingacar she’ll see something interesting every day❤️ - The power stroke in a diesel engine (often misspelled as “Fidel engine”) happens after the air-fuel mixture is compressed and fuel is injected. Here’s how it works: In the power stroke, the compressed air inside the cylinder gets fuel injected directly into it. Due to the high compression, the air is extremely hot, causing the fuel to ignite spontaneously (without a spark plug). This combustion forces the piston downward, generating
