摘要:
A separate lubricating device for an internal combustion engine includes a lubricating oil injection nozzle for injecting a lubricating oil into a passage of an air intake system and an electric deliverer for delivering a lubricating oil from an oil tank to the lubricating oil injection nozzle. The electric deliverer is positioned remotely from the lubricating oil injection nozzle. The electric deliverer may, to special advantage, be housed inside the oil tank.

An electronic ignition system of the capacitor-discharge type for an internal combustion engine includes a magneto generator having substantially a single generating coil with no center tap, and includes a change-over circuit which changes over the supply of power generated from the generating coil from the capacitor to an auxiliary unit when the capacitor is charged to a given voltage by the half-waves of one polarity of the alternating electromotive force generated in the generating coil. The opposite-polarity half-waves of the alternating electromotive force are supplied to the auxiliary unit even while the capacitor is being charged.
摘要:
A device for preventing radio frequency interference generated by spark plug of internal combustion engines. The device includes a cover member adapted to cover at least a part of the high-voltage portion of the spark plug such as high-tension cord together with the end of the plug connected to the cord. The cover member is made of a highly soft, flexible and electrically conductive rubber material (high molecular compound). The cover member is grounded through a grounding line to the body of the engine. This device is suitable for use in machines having limited space for mounting the radio frequency interference prevention device, such as chain saw having an internal combustion engine.

A reciprocating pump includes a chamber, a reciprocating member arranged to induct a fluid into the chamber and discharge the fluid from the chamber to a delivery side of the pump, and a piezoelectric element attached to the pump and arranged to detect pressure fluctuations on the delivery side of the pump so as to sense any abnormality in the inducting and discharging of fluid.
摘要:
A separate lubricating device for a two-stroke internal combustion engine provided with an air intake system and a controlling device includes an injector for injecting lubricating oil into a passage of the air intake system and a lubricating control device associated with the controlling device. The lubricating control device controls the timing and quantity of injection of the lubricating oil into the engine.

A strapping machine is disclosed which is adapted to be capable of constantly attaining a stable secondary tightening force and thereby capable of preventing a band from coming off the object under strapping, which enables a reduced power consumption cost to be realized, and which can be constructed simply and inexpensively as a whole. The strapping machine comprises a feed/backfeed stepping motor M2 as a source of driving force for a mechanism F including a feed/backfeed roller 8 for conducting feed and backfeed of a band B to be looped around a periphery of an object to be strapped and the like operation; the strapping machine being provided with a reverse rotation preventive means 87, S for timely locking rotation of the feed/backfeed roller 8 in the feed direction D.sub.F of the band B while always permitting rotation of the feed/backfeed roller 8 in the backfeed direction D.sub.B of the band B.
摘要:
An internal combustion engine apparatus including an internal combustion engine having an ignition system and a centrifugal clutch. The ignition system is capable of being in delayed ignition timing in a range of low engine speeds and being in advanced ignition timing in a range of high engine speeds while quickly changing ignition timing stepwise when the engine speed is at a predetermined level between the low and high engine speed ranges, and the centrifugal clutch is switched between a condition of engagement and a condition of disengagement at an engine speed in the vicinity of the predetermined engine speed. The apparatus retains the advantages of an internal combustion engine having a centrifugal clutch and allows a machine for which the apparatus is used to make effective use of engine output power. The apparatus has improved engine startup characteristic and increased engine stability and is free from engine stall when the centrifugal clutch is not fully engaged.
