Gas Otto Engines

GAS-OTTO-MOTOR in einem SchalldämmcontainerGas Otto engines work according to the internal combustion principle, and have been specially developed for operation with gas. The operation with high-grade combustible gasses such as methane (CH4), the main constituent of natural gas, is characterised through a high degree of efficiency, a clean combustion and a good CO2 balance.

In order to minimise the nitrogen oxide emissions, the engines are operated as so-called “lean-burn engines” with a high degree of excess air.

Gas Otto engines are applied, amongst other things, for energetic utilisation of lean gases which are created during the fermentation of organic wastes (biogases and landfi ll gases).

Gas Otto engines can also be operated with other types of gases such as natural gas or propane gas, which can be useful for starting biogas plants in order to provide the necessary process heat.

The SEVA Energie AG produces block-type thermal power stations for small and medium-size gas engines in the power range from 50 kW to 4,000 kW. The well-develop ed technology enables safe operation of these engines with biogas under compliance with waste gas limits according to TA air.
