Abstract (en)
[origin: US4840154A] A tubular ceramic body for gas passages in a cylinder head of an internal combustion engine comprises a tubular piece having an opening, two separate tubular portions each having an end side and provided with an opening at the end side, the tubular portions merging into the tubular piece in a transition region, and a connection provided between the tubular portions at least in the transition region of the tubular portions into the tubular piece, the ceramic body being formed as a one-piece member produced in a single sintering process from a single material, and the connection of the tubular portions being formed by a common wall.
