Can Engine Oil Lubricate the Chain?

[DiColin]

Engine oil can lubricate the chain. Engine lubricating oil can even lubricate gears, so it's definitely no problem for the chain. Structure of the timing chain lubrication oil path in the engine: It includes the engine block and oil passages. The front end face of the block is equipped with an oil nozzle. Inside the engine block, there are short oil passages, main bearing lubrication oil passages, and the engine main oil passage. The oil nozzle is located above the timing chain and is connected to the main bearing lubrication oil passage via the short oil passage. The other end of the main bearing lubrication oil passage is connected to the engine main oil passage. Distance between the oil nozzle and the timing chain: The oil nozzle is close to the timing chain, allowing lubricating oil to be directly sprayed onto the timing chain, ensuring simple and reliable lubrication. The connected lubrication oil passage is short, and the distance to the main oil passage is close, resulting in minimal oil pressure loss. This setup ensures high-pressure lubricating oil, guaranteeing that the timing chain receives sufficient, stable, and timely cooling lubrication during operation.
