Abstract: A mesh filter for a fuel system of a vehicle may include: a frame for maintaining a shape thereof; a mesh member coupled to the frame so as to remove foreign substances contained in fuel, where the mesh member includes a first mesh member and a second mesh member; and an opening unit for opening and closing a fuel path in the first mesh member. In particular, the second mesh member has a mesh size smaller than a mesh size of the first mesh member such that the mesh filter inhibits clogging of the mesh filter with paraffin wax.

Abstract: A device for screening a NOx sensor provided on a front end of a tail pipe includes a screen, a screen rotating shaft to which the screen is fixed and having a screen lever, a first fixed shaft having a second end that is coupled to or separated from a first end of the screen rotating shaft, and an axial side extension part with a temperature sensitive length extension and contraction part that is opposite to the screen lever, a second fixed shaft having a return spring, a rotary stopper coupled to the screen rotating shaft, and a first fixing plate located inside the front end of the tail pipe and deformed to fix the rotary stopper or to pass the fixed rotary stopper in an opposite direction, wherein each of the first end and the second end is inclined to a side.
