Abstract:
An internal combustion engine comprising a cylinder body defining at least one cylinder bore in which a piston reciprocates, said cylinder bore having a closed end, said closed end defining with said piston and said cylinder bore a combustion chamber, an air induction device configured to supply a volume of air to said combustion chamber when in a first position, said air induction device including an air amount control mechanism configured to adjust the volume of air, and a lubrication device configured to deliver a volume of lubricant to a portion of said engine, said lubrication device including a lubricant amount control mechanism configured to adjust the volume of lubricant in an amount corresponding to the volume of air adjusted by said air amount control mechanism, and a user selectable switchover mechanism connecting the air induction device with the lubricant control amount mechanism and being configured to change the volume of lubricant delivered to the portion of said engine at a particular volume of air, the switchover mechanism having at least first and second positions, the lubrication device delivering a first volume of lubricant to the portion of said engine when the air induction device is in the first position and with the switchover mechanism in the first position, and delivering a second larger volume of lubricant to the portion of said engine with the air induction device in the second position and with the switchover mechanism in the second position.
