What is the cylinder firing order of the Mercedes-Benz 272 engine?

[McRosalie]

When facing the engine, the cylinder firing order of the Mercedes-Benz 272 engine is as follows: on the left side from front to back are cylinders 1, 2, and 3, while on the right side are cylinders 4, 5, and 6. Here is some relevant information about the Mercedes-Benz 272 engine: 1. Design: The Mercedes-Benz 272 engine features a balance shaft installed between the two cylinder banks to counteract the inherent secondary vibrations of a V6 engine, ensuring smooth operation. This balance shaft is driven by the timing chain and rotates at the same speed as the crankshaft but in the opposite direction. The engine uses trapezoidal forged steel connecting rods, which reduce weight by 20%. The piston pin lubrication is achieved by injecting oil from the top of the piston rather than through separate holes in the connecting rods for splash lubrication. Oil jets are installed in the oil passages to cool the pistons. 2. Materials: The cylinder heads and crankcase of the Mercedes-Benz 272 engine are both made of aluminum.
