Fuel - associated petroleum gas
Appointment
Industrial enterprises that require the use of backup/own power sources. Industrial enterprises using drive power plants based on internal combustion engines. Agricultural facilities planning to utilize biogas. Landfills for landfill gas utilization.
Features
Re-equipment of existing 50-1000 kW diesel engines for operation on combustible fuel gases. Possibility of re-equipment for operation both in the gas-diesel mode and in the gas-piston version.
When a diesel engine is converted into a gas-diesel engine, it remains possible to operate on diesel fuel. The replacement of diesel fuel with gas is up to 80%. This type of conversion can be carried out without dismantling the existing fuel equipment and reworking the cylinder block.
When converting to a gas piston engine, the diesel fuel apparatus is changed to a gas one and the compression ratio of the engine changes depending on the type of fuel gas. The converted engine runs exclusively on gas fuel.
