What is the typical firing order for domestic six-cylinder engines?

1-5-3-6-2-4 or 1-4-2-6-3-5. Four-stroke inline six-cylinder engine: The firing interval angle of a four-stroke inline six-cylinder engine is 720 degrees/6=120 degrees. The six crank throws are arranged in three planes, with a firing order of 1-5-3-6-2-4. Firing order for V6 engine: For a V6 engine, it's essential to first clarify the cylinder numbering sequence since V-engine cylinder numbering methods vary. Generally, when sitting in the driver's seat, if the right bank cylinders are numbered 1, 3, 5 from front to rear and the left bank 2, 4, 6, the firing order is typically 1-4-5-2-3-6. If the right bank is numbered 2, 4, 6 and the left bank 1, 3, 5, the firing order is usually 1-6-5-4-3-2. The firing interval angle for four-stroke V6 engines remains 120 degrees, with three crank throws at 120 degrees to each other. The working sequence is R1-L3-R3-L2-R3-L1. Facing the engine's cooling fan, the right bank cylinders are denoted by R (R1, R2, R3 from front to rear) and the left bank by L (L1, L2, L3), forming the working cycle.
When it comes to the firing order of domestic six-cylinder engines, I find it quite interesting. Generally speaking, for inline-six engines in cars like Haval or Geely, the firing order is 1-5-3-6-2-4. This arrangement helps prevent excessive engine vibration, making the ride smoother. Having been into cars for several years, I've studied its principle: each ignition occurs at 120-degree intervals, balancing force distribution and reducing noise. Some V6 models might have variations, but most domestic cars stick to this order for its simplicity and reliability. In daily driving, this design contributes to fuel efficiency and quiet operation, making it particularly suitable for everyday use. I recommend checking the ignition system during maintenance to avoid carbon buildup affecting ignition. Understanding this better can make you smarter in car selection and easier in maintenance. Domestic engines have indeed made significant progress in recent years.
I remember one time when my car's engine was shaking, I took it to the repair shop for inspection, and the mechanic said it was a common issue with the firing order. In domestic six-cylinder engines, such as those from Baojun or Chery, the firing order is typically 1-5-3-6-2-4. The advantage of this design is that the ignition intervals are uniform, preventing vibration caused by simultaneous operation of cylinders, making the car run smoothly. You can feel the difference in daily driving: orderly ignition, smooth acceleration without abruptness, and especially good fuel consumption control during high-speed cruising. After learning this, I also pay attention to the position of the ignition coils during maintenance to ensure they are not misaligned. Domestic engines follow this sequence using proven technology, which is trustworthy. Less jargon, more sharing of practical experiences.
