Summary

The amendment of the German Renewable Energy Act in 2004 led to a major upturn in business in the biogas sector. Biogas can be combusted in stationary four-stroke carburettor engines. The main constituents of biogas are carbon dioxide and methane, which are generated in a fermentation process, e.g. from renewable raw materials. Since, generally speaking, the carbon dioxide emissions in exhaust gases are responsible for the global temperature increase, stationary gas engines fuelled with biogas can ensure a more even carbon dioxide balance than with fuels produced from crude oil and with engines which are fired by such fuels. This paper presents two newly developed stationary biogas engines from MAN's extensive product range. The goals of the development were to achieve high effective efficiencies and lower carbon dioxide emissions in the exhaust gas. The integral heating progression based on the 1st law of thermodynamics is used to describe the combustion.
