    Turn the crankshaft until the piston of the cylinder to be adjusted comes into ......

    Hello everybody!

    Turn the crankshaft until the piston of the cylinder to be adjusted comes into the ignition dead centre position.


    Which shall be adjusted: piston or cylinder?


    Suppose the piston of the cylinder is to be adjusted.


    Then the sentence would read as follows:


    Turn the crankshaft until the piston of the cylinder which shall be adjusted comes into the ignition dead centre position.


    or a little awkwardly


    Turn the crankshaft until there comes into the ignition dead centre position the piston of the cylinder which shall be adjusted.


    What is your opinion?


    Thank you
    .

    Turn the crankshaft until the piston of the cylinder to be adjusted comes into the ignition dead centre position. Ambiguous

    Turn the crankshaft until the piston of the cylinder which shall be adjusted comes into the ignition dead centre position. Ambiguous and unnatural

    "the piston of the cylinder to be adjusted" means "the piston of the cylinder that/which is to be adjusted", doesn't it?

    Yes, but it's still ambiguous.

    What is ambiguous?

    The fact that "the piston of the cylinder that/which is to be adjusted" or "the cylinder that/which is to be adjusted".

    I am in two minds about it.

    It could be the piston or the cylinder that need to be adjusted.

    I would be grateful for help from an engine expert.

    I'm by no means any kind of engine expert, but I do know that the piston is the moving part. The cylinder is just a hole that the piston moves up and down in. You can't really adjust a cylinder, aside from boring them out to make them larger. You can however adjust the movable piston.

    I think you want something like "Turn the crankshaft until the piston to be adjusted comes into (top) dead center of ignition."

    However, that's a fuzzy guess based off the Wikipedia entry.

    Yes - the cylinder‘s just a hole in the engine block. The piston and the crankshaft are the only relevant moving parts, and their relationship is fixed. When you turn the crankshaft, the piston moves (or, if the motor‘s running - when the piston moves, the crankshaft turns).

    I am no engine expert, but I agree the piston and the crankshaft move, not the cylinder. I think your first sentence makes sense if two commas are added, because the piston and cylinder are almost one unit.
