Problems solved by technology

However, this does not provide a solution for those cases where there is only one internal combustion engine operating on a single gas, which is often the case with large two-stroke diesel internal combustion engines in marine vessels

Embodiment Construction

[0049] In the following detailed description, an internal combustion engine will be described in an exemplary embodiment with reference to a large two-stroke, low-speed turbocharged compression ignition internal combustion engine with a crosshead, but it should be understood that the internal combustion engine may be of another type, for example with or without Two-stroke Otto, four-stroke Otto or diesel with turbocharging, with or without exhaust gas recirculation.

[0050] figure 1 , figure 2 with image 3 A large low-speed turbocharged two-stroke diesel internal combustion engine with crankshaft 8 and crosshead 9 is shown. image 3 A schematic diagram of a large low-speed turbocharged two-stroke diesel internal combustion engine with an intake system and an exhaust system is shown. In this exemplary embodiment, the internal combustion engine has six cylinders in a row. Large low-speed turbocharged two-stroke diesel internal combustion engines typically have a row of fo...

Abstract

The invention relates to an internal combustion engine with a fuel gas property measurement system. An internal combustion engine comprising one or more cylinders (1), a combustion cell (40), a fuel gas supply system (30) configured for supplying a flow of fuel gas at a given pressure and temperature to the cylinders (1) and configured for supplying a flow of the fuel gas at the same given pressure and temperature to the combustion cell (40). The one or more cylinders (1) each being provided with at least one gas admission valve (31), the combustion cell (40) being provided with a nozzle (49) for injecting the flow of fuel gas from the fuel gas supply system (30) into the combustion cell (40). The engine further comprises a supply line (42) for supplying a flow of oxidizer gas to the combustion cell (40), an exhaust conduit (47) for conveying a flow of combustion gas away from combustion cell (40) and a sensor (48) for measuring the proportion of oxygen in the flow of combustion gas.

Description

technical field [0001] The invention relates to an internal combustion engine which operates on fuel gas. Background technique [0002] Internal combustion engines using the Otto or diesel principle (eg two-stroke internal combustion engines, four-stroke internal combustion engines) can be operated with liquid or gaseous fuels. In order for a modern internal combustion engine to operate correctly, it is necessary to know exactly how the engine is loaded. This information is needed to control various parameters such as injection timing and length exhaust valve opening timing and length, variable turbocharger settings, SCR (Selective Catalytic Reduction) settings, EGR (exhaust gasrecirculation, exhaust gas recirculation) settings, injected gas pressure, hydraulic system pressure, exhaust bypass opening, cooling fan speed, coolant pump settings. This is not exhaustive and depends on the type of internal combustion engine. However, all internal combustion engines have in comm...
