  • Lightweight back-pack generator set having a spark-ignited engine operating on middle distillate fuels
    Patent number: 5555853
    Abstract: A lightweight back-pack generator set having a spark-ignited engine operating on middle distillate fuels (e.g., JP-5, JP-8 and F-34) has been provided. The generator set includes a back-pack frame; an alternator; and a spark-ignited combustion engine adapted to operate on a middle distillate fuel. The engine uses a preheater for heating the intake manifold to facilitate start-up operation of the engine. The present invention also provides a simple and inexpensive method for converting a spark-ignited gasoline engine to operate on a middle distillate fuel for providing a lightweight engine suitable for driving an alternator, a portable generator, or other portable equipment.
