Fuel, Air, Spark, Compression, Timing

Long before we get to disc brake upgrades, Shelby drops and changing gearing ratios, we've got to bake our combustible recipe. Every engine needs five things to roar to life: fuel, air, spark, compression, and timing. Miss just one, and you’re probably listening to this episode on the side of the road. Today, we break down the mechanics behind the machines—and the lessons they teach us about precision, balance, and getting it all to fire in sync. Welcome to Ford Mustang: The Early Years and Ford Trucks, the Early Years Podcasts, where today we will get you tuned up and on the road. Let's bring in our resident expert, Jonathan, welcome back to the podcast -- it's been way too long.

That’s the whole recipe for a running engine:

• Fuel – Correct amount of gasoline delivered into the cylinder.
• Air – Oxygen mixed in the right ratio with fuel for combustion.
• Spark – Ignition source (spark plug, or compression ignition in a diesel) to light the mixture.
• Compression – Pistons squeezing the air/fuel mixture to the right pressure for efficient burn.
• Timing – All of the above happen at exactly the right moment in the engine cycle.

If any one of those is missing or out of sync, the engine won’t run properly.
