Definitions

  • the present invention relates to improvements to engines, and particularly internal combustion engines.
  • the most commonly known type of internal combustion engine is the reciprocating piston engine, where the linear reciprocating movement of the pistons is driven by fuel ignition and combustion.
  • crankshaft The linear motion of the pistons is converted into a rotary motion by the crankshaft.
  • crankshaft is positioned external to the engine block and provides a portion to connect the engine to devices such as to the drive of a vehicle or an electrical generator.
  • crankshafts and engine blocks especially if the engine has multiple pistons and cylinders.
  • the need for such large and heavy parts is in part as a result of the high forces transferred by the piston to the crankshaft (and engine block via bearings) at initial ignition, as the journal to which the piston connects on the crankshaft is in line, or close thereto to the line of travel (and force) of the piston and connecting rod at the time of ignition.
  • Conventional engines have a head component (or part), that is complex and troublesome because the inside of the head at each cylinder region forms one of two main sides to the combustion chamber and is joined there by a head gasket and bolts, and it is against this head that combustion pressure exerts itself to cause the piston to move.
  • Patent number GB488336 discloses a rotary engine that is composed of exposed single cylinder engines or cylinders that rotate but do so driven by the crankshaft primarily. It does not claim an invention having a cylinder positioned to obtain the best leverage and the prime mover to give rotation. Therefore this engine would have a similar per cylinder performance as a conventional engine.
  • the fixed portion is a casing.
  • the cylinder block is a rotor.
  • the fixed portion retains that rotor such that the rotor is free to rotate about an axis of rotation passing through its centre.
  • the piston is oriented within the cylinder block such that the magnitude and sense of combustion are directed so as to maximise rotational effect of the cylinder block around its axis of rotation, relative to the fixed portion.
  • the piston has attached to it driving means that convert its reciprocating motion to a circular motion that assists in rotating the cylinder block relative to the fixed portion.
  • the driving means for each piston include a connecting rod, a crankshaft, and at least one pinion gear connected to the crankshaft such that the pinion gear engages at least one ring type gear fixed to the fixed portion.
  • the piston is oriented in a plane normal to the centre of rotation of the block.
  • the piston is oriented with its head pointed in the direction that the cylinder block will rotate.
  • the piston is offset form the centre of rotation of the block.
  • the invention may be said to lie in a method of effecting a cycle of an engine wherein as a working fluid in a cylinder bore expands and drives the cylinder and a block in opposing directions, this in turn rotates a pinion gear that is connected to a crankshaft, the pinion gear engages a ring type gear fixed to a fixed portion, such that the rotation of the pinion gear on the ring type gear rotates the cylinder block relative to the fixed portion thereby providing a work output, whilst simultaneously driving the piston back into a position where it can accept and then compress a fresh charge.
  • the fresh charge comprises fresh working fluid.
  • the fresh charge comprises working fluid and fuel.
  • the working fluid is air.
  • the working fluid is steam.

  • said piston is adapted to be attached to said rotor in a manner that enables the piston to move in effect back and forth in the rotor even while the rotor is spinning.
  • Such movement is of a limited distance reciprocal in nature or in effect reciprocating. The movement is provided so that the piston can create a stroke and assist to create a combustion chamber and cycle.
  • the said piston obtains said movement on the rotor by being attached to the rotor on above said arm or (a connecting arm or rod or plate mechanism).
  • a connecting arm or rod or plate mechanism Preferably the connection of the arm to the rotor in one example is with the arm's first end fixed close to the rotor centre, thereby creating and allowing the arm's backwards and forward movement to be pivotal from the rotor centre, thereby the pistons movement in the cylinder on the arm in the rotor is upon the same radius as the cylinder radius.
  • the arm is located in an aperture in the rotor, such aperture having a first and second side and a first and second end, each preferably parallel to each other and again slot like in design, so that the rotor has a continuous surface on either side to enable it to rotate within the cylinder slot, and to which sides of the rotor seals or bearings can be fitted or engaged upon.
