Abstract

An internal combustion apparatus is disclosed having a linear output. A metered quantity of gas fuel is transferred between a cylinder head and the disc of a plunger reciprocable in a principal chamber between top and bottom end of stroke positions. In the displacement of the plunger to its bottom end of stroke position air and fuel are intimately mixed in a one-way flow path around the disc including nonparallel and/or burred orifices in a perforate plate attached to the plunger. The fuel may be liquefied gas fuel in which case it may be vaporized by the combustion gases exhausted from the principal chamber to the surroundings through an annular exhaust zone coaxial of throttle passageways for carrying fuel from the metering piston to the principal chamber. Alternatively, a pressurized gas fuel may be used in which case the pressurized gas is utilized in the operation of the plunger.
