- Firing order, from CCW and CW
This is my question, the reason for the difference in the firing order What is for diesel engines? Example CCW 1,5,3,6,4,2 CW is a 1,42,6,3,5
Balance? A little more information would be useful.babakN said:TL;DR Summary: Firing order, from CCW and CW

Welcome, @babakN !babakN said:This is my question, the reason for the difference in the firing order What is for diesel engines?
The firing order in marine diesel engines is determined by various factors including engine balance, smooth operation, and minimizing vibrations. The specific application and design of the engine also play a significant role in determining the optimal firing order.
The firing order affects engine balance by influencing the distribution of forces and moments within the engine. A well-chosen firing order helps to balance the reciprocating masses and reduce torsional vibrations, leading to smoother engine operation and reduced wear on components.
Minimizing vibrations is crucial in marine diesel engines to ensure the longevity of the engine and the comfort of the vessel. Excessive vibrations can lead to mechanical failures, increased maintenance costs, and discomfort for crew and passengers.
Yes, certain firing orders are more commonly used in marine diesel engines due to their proven effectiveness in balancing forces and minimizing vibrations. However, the specific firing order can vary depending on the engine configuration, such as inline, V-type, or opposed-piston designs.
Changing the firing order in an existing marine diesel engine is generally not feasible without significant modifications. The firing order is intricately linked to the engine's design, including the crankshaft and camshaft configurations, and altering it would require substantial engineering changes.
