An air intake system for intake air of an internal combustion engine comprising a filter insert (19) in a housing (10) connected to the air conducting system by a plurality of inlets (13) and an outlet (22). The air inlets are provided with individual intake nozzles or fittings and lead to a single common air chamber (20) in the filter housing. The inlets (13) can be individually opened and closed by flap valves (24), thereby allowing the acoustics to be influenced favorably and enabling, for example, the respective intake fittings to be connected or disconnected depending on the temperature. The intake system requires only a limited number of components, and the design of the preferably wedge-shaped air chamber minimizes flow losses in the housing, which in turn decreases the intake noise. Shunt resonators (28) can also be formed using cover elements (29) and (30).

Opposed piston, compression ignition engine with single-side mounted crankshafts and crossheads

In an opposed piston, compression ignition engine two crankshafts are single-side mounted with respect to a row of cylinders, which is to say that the crankshafts are mounted so that their axes of rotation lie in a plane that is spaced apart from and parallel to a plane in which the axes of the cylinders lie. Each piston of the engine is coupled to one of the crankshafts by a single linkage guided by a crosshead. The piston has a piston rod affixed at one end to the piston. The other end of the piston rod is affixed to the crosshead pin. One end of a connecting rod swings on the pin and the other end is coupled to a throw on a crankshaft. Each crosshead is constrained to reciprocate between fixed guides, in alignment with the piston rod to which it is coupled.
