FIRING ORDER

All about engine! as we are know the method of how to run 4 stroke engine 🚂🚒 as; the piston goes 2 time toward bdc then become first stroke: that's a logical; we will note the setuation in this time the piston goes 2time toward bdc and then twice towards tdc: it means the crankshaft also does complete two round, and the important is out of the remaining four stroke, the power gain only from power stroke, it means we get one power stroke when the crankshaft does complete ("720°") round, the power of the power stroke live first too much but slowly slowly it become low for 3 adlar stroke i mean the 3 stroke they're helper stroke they're suportting stroke also they're necessary 😜🙂, and that's why the vehicle 🚜🚑 not always at the same Speed 🚅, but the new generation have more engine power by increasing more piston.🤕😜 and for this problam we need to encrasse engine valumetric efficiency , but its also have some dignity thank you ,❤️
