How are the cylinders arranged in the Teana V6 engine?

The six cylinders of the Teana V6 are divided into two rows, with three cylinders in each row. The left side consists of cylinders 1, 3, and 5, while the right side has cylinders 2, 4, and 6. Below are specific details about the V6: Definition: V6 refers to the number of cylinders and their arrangement in the engine. V6 indicates a six-cylinder engine with a V-shaped cylinder arrangement. In this configuration, each cylinder works in harmony with the others, resulting in minimal noise and very smooth operation. V-shaped engines have compact length and height dimensions, making them very convenient to install. Additionally, V-shaped engines are generally considered more advanced and are often seen as a hallmark of higher-end vehicles, typically installed in mid-to-high-end sedans.

I've studied quite a few V6 engine layouts, and the Teana's V6 is a classic 60-degree V configuration with 3 cylinders on each side. This design is more compact than an inline-6 and offers better vibration control than a 90-degree V6. Its piston movement is like two people facing each other trying to shake hands—working alternately left and right. Nissan has tuned this VQ series with exceptional refinement; at idle, you can barely feel any vibration, and when you rev past 4,000 RPM, the distinctive howl of the V6 is particularly thrilling. When removing the intake manifold, you can see the cylinder block arranged like two rows of soldiers standing at an angle, with a firing order of 1-2-3-4-5-6 in a cross-firing sequence. This design makes the power delivery as smooth as silk.

When disassembling the old-generation Teana's VQ35 engine last time, we measured its two-row cylinder bank angle at exactly 60 degrees. Each row has three cylinders arranged in a staggered pattern, with crankpins spaced at 120-degree intervals. The brilliance of this design lies in its balance – traditional inline-6 engines are too long to fit neatly into engine bays, while 90-degree V6s require balance shafts that add weight. Nissan engineers eliminated the need for balance shafts with this 60-degree configuration, pairing a cast iron block with aluminum cylinder heads to keep the weight at around 178kg. I recall cylinders 1-6 being on the right side and 2-4 on the left, with knock sensors monitoring each cylinder's ignition during startup. The rhythmic movement of the six pistons rising and falling was like a mechanical ballet.

With over 20 years of car repair experience, I've worked on at least a hundred Nissan Teana V6 engines. Opening the hood reveals the distinctive V-shaped layout—three spark plugs lined diagonally on the left, mirrored symmetrically on the right. During maintenance, note the cylinder numbering: viewed from the front, left side houses cylinders 1/3/5, right side 2/4/6. This configuration lowers the engine's center of gravity, enhancing cornering stability. Replacing spark plugs requires removing the intake manifold first, with cylinder #6 being the trickiest—only accessible using a universal joint wrench. Compared to inline engines though, V6's pulley system maintenance proves relatively simpler.
