The LV-1 Liquid Fuel Engine is used to provide thrust to a rocket, and is currently the weakest liquid fueled engine available. It has a relatively poor impulse compared to other liquid fueled engines but is useful on small satellites due to its size and very low mass. There is a radial derivative of this engine called LV-1R Liquid Fuel Engine featuring the same engine properties and similar design.

No fuel bar appears next to LV-1 engines when they are active, so the general resource widget is the best way to see how much fuel is left.
