Definitions

  • the present invention relates to a system for the independent lubrication of an internal combustion motor having a two-stroke engine fed with a gaseous combustible such as GPL which is a liquefied petroleum gas, methane and similar gases.
  • GPL gaseous combustible
  • the first object of the invention is to apply a lubrication system of the cylinder to internal combustion motors having a two-stroke engine planned and constructed for functioning with feeding the mixture and subsequently is fed with a gas and to provide a system which in addition to providing for safe and accurate functioning is also of a simple construction, quick mounting and limited cost.
  • Another object of the invention is to provide a lubrication system adapted for installation in an internal combustion motor operating with a two-stroke engine fed with only benzene rather than with a mixture of benzene and oil.
  • Still another object of the invention is to provide a lubrication system for an internal combustion motor having a two-stroke engine which is applicable to motors planned to function with a mixture and with a gas alternatively.
  • a further object of the invention is to provide a lubrication system for an internal combustion motor having a two stroke engine applicable to motors which have been planned for functioning alternatively with a mixture and with a gas.
  • the system according to the present invention comprises a mechanical pump of normal production, a reservoir for the oil of lubrication provided with a level sensor, tubing for sucking which connects the reservoir with the pump and an injection tubing which connects the pump to the conduit which feeds the combustible into the motor.
  • the pump used for feeding the lubrication oil receives the motion of rotation directly from the motor by means of a transmission structure which connects the pump with the shaft of the motor.
  • Figure 1 shows the main components of an internal combustion motor operating with a two stroke engine which can function alternatively with benzene or a gas.
  • the internal combustion motor (1) operating with a two-stroke engine puts in rotation by means of the transmission structure (2) keyed to the shaft of the motor or on another derived structure the pump (3) which feeds the sucked in lubrication oil by means of piping (4) from reservoir (5) and sent to the motor by means of a piping (6) which is connected to the entry conduit (7) of the combustible in the motor.
  • the reservoir (5) is provided with an automatic breaker preferably of the floating type which provides by means of an electrical circuit to interrupt the electrical current supplied to the sparking plugs and therefore blocks the motor when the level of oil in the reservoir is less than the minimum level.
  • the system according to the present invention is mounted on a vehicle provided with a functioning circuit of the motor with liquid combustible and a functioning circuit of the same motor with a gaseous combustible, these devices being disposed parallel with respect to the entry conduit of the combustible and functioning alternatively.
  • Circuit A for the functioning of the liquid combustible is composed essentially by the reservoir of the mixture (8), the air filter (9) and carburator (10).
  • Circuit B for the functioning of the gaseous combustible is composed essentially by the reservoir of gas (11), the pressure reducer (12) and a mixer (13) for the gas and air.
  • the quantity of oil necessary for the lubrication of the structures of the motor depends on the number of turns of the motor and the load of the same motor so that the pump (3) which feeds the oil is controlled by the shaft of the motor and also by the position of the manual accelerator (14) which is communicated to the pump through the cable (15).
