Abstract

The present invention relates to a valve monitoring system (A), that can be applied in all suitable areas, especially in two- and four-stroke heavy-load diesel machines and generators, that run primarily with diesel/fuel oil, LPG, LNG, CNG, and similar fossil fuels, which are used as main propulsion machinery on ships and as generators in power plants on land, and that prevents/minimizes valve failures by providing remote monitoring of each valve (1) separately, and the rotation speed, temperature, and position values of the inlet and exhaust valve (1), which should be present in each cylinder as standard, in two and four-stroke diesel machines and generators.
