Abstract: An arrangement for internal combustion engines of the piston engine type having at least one row of cylinders is disclosed. The arrangement includes at least one fuel injector for each cylinder and at least one intake manifold for admission of air to the cylinders. The inlets of the fuel injectors are connected to a fuel channel arranged in the intake manifold.

Abstract: The present invention relates to an arrangement for an inlet pipe in a rotating drum sieve for the supply of sludge or a liquid mixed with particles to the inside of the rotating drum sieve, which drum sieve exhibits flow openings along its casing, in order to permit the separation of fluid from the sludge, etc., supplied to the internal space of the drum via plurality of discharge openings extending along the longitudinal axis of the drum and capable of being accommodated in the internal space of the drum. The invention permits the effective supply of sludge, etc., to the drum sieve in both small and large flows without the risk of blocking the inlet pipe. At least two simultaneously effective discharge openings for the supply of sludge. etc., to the internal space of the drum are situated on levels separate from one another.
