<p>A lubricator for a cylinder of an internal combustion engine includes an electric motor for forcedly feeding lubricating oil in an oil tank to an accumulator, one or more control valves for feeding the lubricating oil in the accumulator to the cylinder, a pressure detector for detecting a pressure of the lubricating oil in the accumulator, and a controller for supplying a drive command to the electric pump so that the pressure of the lubricating oil in the accumulator is equal to a predetermined value on the basis of a lubricating condition, an operation condition and a signal of the pressure detector and for deriving one or more end-of-lubrication timings on the basis of the lubricating condition, the operation condition and one or more established start-of-lubrication timings to supply to the control valve with a valve opening command when a crank angle is coincident with the start-of-lubrication timing and with a valve closing command when the crank angle is coincident with the end-of-lubrication timing. A lubricator for a cylinder of an internal combustion engine includes a plurality of accumulators for holding lubricating oil fed from an oil tank by a pump to a predetermined pressure, a solenoid controlled valve disposed between the pump and the accumulator, one or more control valves for feeding the lubricating oil in the accumulator to the cylinder, and a controller for selecting an accumulator to be used on the basis of a lubrication condition and an operation condition to supply a switching command to the solenoid controlled valve and deriving one or more end-of-lubrication timings on the basis of the lubrication condition, the operation condition and one or more established start-of-lubrication timings to supply to the control valve with a valve opening command when the crank angle is coincident with the start-of-lubrication timing and with a valve closing command when the crank angle is coincident with the end-of-lubrication timing.</p> |
