How quickly should two chariots mate a bare general?
These answers restate the rules implemented by our open-source engine, which follows the WXF laws and is regression-tested against the official 110-diagram repetition casebook. Where an answer refers to a specific position, that position lives on the linked reference page, where the build verifies it against the engine before publishing.
Direct answer
A handful of moves, with no help needed from any other piece. Because two chariots together control six of the palace's nine points, the mating pattern, known as 雙車錯, does not require patience the way single-piece mates do; the main risk is not technique but rushing into a check that lets the general slip to the one point still uncovered.
The method
Bring one chariot to control a rank the general could retreat to, then check with the other. As long as the two chariots are working on adjacent ranks rather than duplicating coverage, the general runs out of safe points almost immediately.
The one mistake to avoid
Checking before the second chariot's coverage is actually in place just pushes the general to the remaining open point and wastes a move. Confirm both chariots' coverage first, exactly as with any other mate, and only check once the net is complete.

Does the sixty-move rule ever bite here?
Essentially never with correct technique; this mate is one of the fastest in the game.
What if the opponent still has an advisor?
Considerably harder. See what 雙車錯 requires for the bare-general version specifically.
