What is the firing order of an 8-cylinder engine?
1 Answers
8, 10, and 12-cylinder engines are generally arranged in a V-configuration, but the firing order is closely related to the crankshaft arrangement. There are many choices for the firing order, which determines the structural form of the crankshaft. Generally, the angle of the V-type engine is considered, and the crankshaft arrangement is determined based on the balance requirements of operation. The firing order is also determined based on factors such as bearing load and exhaust piping. It is necessary to consider both uniform firing intervals and the balance of first- and second-order inertial forces and moments, as well as engine torsional vibration and many other aspects. Generally, four-stroke engines with an even number of cylinders per bank use a 360-degree interval angle and cross-firing between the left and right cylinder banks. Below is more related information: V-type engine: For a V6 engine, it is important to understand the cylinder sequence because the numbering method for cylinders in a V-type engine is not uniform. Generally, when sitting in the driver's seat, if the cylinder sequence on the right side from front to back is: 1, 3, 5, and on the left side from front to back is: 2, 4, 6, the firing order is usually: 1-4-5-2-3-6. If the right side from front to back is: 2, 4, 6, and the left side from front to back is: 1, 3, 5, the firing order is usually: 1-6-5-4-3-2.
