Gasoline engines or diesel engines can be modified for natural gas operation, thanks to our fast and precise BFS swing piston pumps and BFS coaxial solenoid valves.
One challenge when modyfying a gasoline or diesel engine for additional operation with natural gas is ensuring adequate lubrication and cooling of the engine’s interior. This is because gasoline or diesel engines are designed for the lubricating and cooling effects of their fuel and the additives it contains. Natural gas, however, has no lubricating effect of its own. It does not cool the engine compartment sufficiently. In addition, natural gas engines tend to coke up. Residues are deposited on the valves, which can even afterglow and ultimately damage the engine.
To ensure sufficient lubrication, cooling and cleaning during operation with natural gas, additional additives must therefore be injected into the intake manifolds and dosed accordingly.
This is where our fast and precise BFS vibrating piston pumps and BFS coaxial solenoid valves come into play. Thanks to their O-ring-less liquid gap seal, our pumps deliver a constant flow rate over their entire service life. Designed and strictly monitored as part of our quality assurance process, they ensure that the necessary amount of additive is always available to the engine. In addition, these pumps and valves are very small and lightweight.
Thanks to their short switching times of only a few milliseconds and their very low dispersion in the metering of the volume flow due to their design, BFS coaxial solenoid valves are particularly suitable for distributing the additives to the individual cylinders. Injection can take place either as a function of engine running speed or at fixed intervals. Control by electronic, and the amount of additive is adjusted according to engine running speed and power.
