Explaining a car on Instagram: "An engine’s firing order is the precise sequence in which each cylinder ignites its air-fuel mixture. This pattern is carefully designed to balance power delivery, reduce vibration, and keep the crankshaft spinning smoothly. Different engines use different orders depending on cylinder count and design — for example, a V8 might follow 1-8-4-3-6-5-7-2, while an inline-4 typically fires 1-3-4-2. The firing order is crucial for performance, efficiency, and reliability
