Embodiment Construction

[0054] figure 1 The internal combustion piston engine 10 is schematically described, which is hereinafter referred to simply as an engine. The engine includes a main body 12 or a body, and various parts of the engine known as such have been assembled or constructed in the main body or body. The engine is provided with at least two cylinders 14, which can be arranged in, for example, a V configuration or as figure 1 The same situation is arranged as an in-line engine. The engine is also provided with a device for reducing fuel material escaping to the atmosphere.

[0055] The engine is provided with an intake system 16 having a combustion air receiver 18 which is connected to the cylinder via a passage 20 and an inlet valve 22. The engine is also provided with an exhaust system 24 having an exhaust manifold 26 which is connected to the cylinder via a pipe 21 and an exhaust valve 23. It should be noted that the number of inlet valves and exhaust valves in each cylinder can be mor...

Abstract

Invention relates to an arrangement for reducing fuel material slip to the atmosphere in an internal combustion piston engine with at least two cylinders (14) and at least one turbo charger unit (28), and an exhaust gas system (24) arranged to connect a combustion chamber of each cylinder of the engine controllably by means of an exhaust valve or valves (23) to the atmosphere via a turbine section (28.2) of the at least one turbo charger unit, the arrangement comprising a fuel processing unit (34) for oxidation of fuel material in the exhaust gas of the engine the arrangement comprises a body (102) through which a conduit (32) is arranged to extend into the vicinity of the exhaust valve at least partly via the exhaust gas system, and the fuel processing unit is arranged in connection with to the conduit (32). Invention relates also to method of upgrading an internal combustion piston engine.

Description

Technical field [0001] The present invention relates to a device for reducing fuel materials escaping to the atmosphere in an internal combustion piston engine, the engine having at least two cylinders and at least one turbocharger unit, and the engine has an exhaust system, the exhaust system Arranged to communicate in a controlled manner the combustion chamber of each cylinder of the engine with the atmosphere via the turbine section of at least one turbocharging unit by means of an exhaust valve, the device includes a device for controlling the fuel material in the exhaust of the engine Oxidized fuel processing unit. [0002] The invention also relates to a method for improving an internal combustion piston engine having at least two cylinders and at least one turbocharger unit. Background technique [0003] Due to the increased interest in efficient and environmentally friendly on-site power production equipment, gas-fueled internal combustion engines powered by engines are ga...
