Detailed explanation-1: -Straight-six engines typically use a firing order of 1-5-3-6-2-4, which results in perfect primary and secondary balance. However, a firing order of 1-2-4-6-5-3 is common on medium-speed marine engines.
Detailed explanation-2: -Most 4-cylinder engines have a firing order of 1-3-4-2 although other firing orders such as 1-3-2-4, 1-4-3-2, 1-2-4-3 are possible. Consider the inline 4 engine in Figure 1.
Detailed explanation-3: -See, 1-8-4-3-6-5-7-2 is the most common firing order for old V8 engines. It’s used for big-and small-block Chevys and Mopars plus Buicks, Pontiacs, AMCs, most Oldsmobiles, and even DeSotos, Packards, and Studebakers. Probably more. It’s the most unifying V8 engine spec on Earth!
Detailed explanation-4: -Explanation: The firing order in these engines is 1-4-3-2.
