    Abstract: Boosted internal combustion engine (IC) provided with valve actuation system (VA), the combustion engine comprising a head (H) where a poppet valve (V) is arranged in such a way to open protruding in the combustion chamber and to close against a corresponding seat, the valve communicating the combustion chamber with an intake manifold (IK), the actuation system (VA) including a pneumatic actuator (PD) comprising a piston (AP) operatively connected with the stem (VS) of the poppet valve (V), at least a first chamber (FC) where the piston (AP) is movable in such a way the first chamber is between the poppet valve and the piston (AP), a spring (SP) arranged to expand the first chamber, wherein the first chamber is fluidly connected with the intake manifold through a pressurization throttled channel (PC) and a pressure sink (SK), which is at a pressure constantly under the intake one, through a controllable valve (SV).

    Abstract: An exhaust gas after treatment system (ATS) for a diesel cycle internal combustion engine (E) has a first and a second particulate filter (F1,F2) arranged in series along an exhaust line (EP), which channels exhaust gas from the engine (E) to an external environment; the first particulate filter (F1) is a soot filter, and the second particulate filter (F2) is an ash filter, which is arranged downstream of the soot filter, considering the exhaust gas direction in the exhaust line (EP), and is suitable to be serviced to allow for removal of collected ash.

    Abstract: A Diesel combustion engine includes at least one cylinder (C) with a respective piston (P) and a respective fire ring (FR) inserted in a stepped housing (FRH) defined in a cylinder liner (CL) so as to surround a respective combustion chamber (CC); an outer surface (OS) of the fire ring (FR), intended to contact the stepped housing (FRH), is shaped so as to include at least one protruding portion shaped as a tip or a ridge and to reduce a thermal exchange between the fire ring and the cylinder liner; an upper edge of the fire ring consists of a cutting edge, in contact with a cylinder head (H) and defining a sealing effect between the fire ring (FR) and the cylinder head (H).

    Abstract: The present invention relates to a dosing module (1) for dosing an urea-based reducing agent into a exhaust gas stream of combustion engine and addressed to an after-treatment system (30), e.g. SCR or SCRT system. The module (1) comprises a housing (20) which develops along a longitudinal axis (X) and an inlet opening (19) for conveying the exhaust gas. Dosage means (55) are provided for dosing the reducing agent. According to the invention, the inlet opening (9) is annular and inclined with respect to the axis (X) of the housing (20) so as to generate an exhaust gas inlet jet (AJ). Moreover the dosage means are designed so as to generate, inside the housing (20), an urea-based reducing agent spray (UWS) coaxial to the axis (X) of the housing (20).
