摘要： PROBLEM TO BE SOLVED: To provide a device for controlling quantity of oil in an oil tank by which even if the quantity of fuel in the oil tank becomes excessive, the fuel level is instantaneously dropped to resolve the troublesome condition.
SOLUTION: The device for controlling the quantity of oil in an oil tank is installed in the engine comprising a lubricating-system fuel-supply path for supplying fuel by a lubrication pump from the oil tank to the engine-lubricating system, an injection-system fuel-supply path for supplying fuel by an injection pump from the oil tank to the injection system, and an injection-system fuel-return path for returning the injection-system return-fuel after being supplied to the injection-system fuel-supply path to the fuel tank. The device for controlling the quantity of oil in an oil tank comprises a bypass passing around the injection system, an opening/closing valve for controlling fuel-inflow into the bypass, and an oil-level sensor for detecting the oil quantity in the oil tank, and further an opening/closing-valve control means for controlling opening/closing of the opening/closing valve on the basis of a value detected by the sensor.

摘要： PROBLEM TO BE SOLVED: To provide a method of operating a reciprocating piston type internal combustion engine in which a fuel is fed into a cylinder and a new lubricating oil is fed to and a used lubricating oil is discharged from the cylinder so that the wear of hard-plated engine parts can be controlled more accurately.
SOLUTION: This method of controlling the wear of the internal combustion engine comprises a step for operating the engine on trial and a step for determining the level of the three-body abrasive wear of the engine parts. The method further comprises a step for changing the configuration of the engine so that, when the abrasive wear is larger than a specified allowable wear, a fuel or the remaining fuel in contact with a cylinder wall can be reduced and/or a step for increasing an ability to remove substances causing the three-body wear from the fuel in a fuel feeder, and/or a step for increasing the abrasive resistance of the engine parts.

摘要： PROBLEM TO BE SOLVED: To provide a diesel engine lubricated with fuel such as diesel oil, for lubricating an engine lubrication system or the like, early consuming fuel susceptible to mixing of a dirty component such as soot therein, and efficiently cleaning exhaust. SOLUTION: The diesel engine 1 lubricated with fuel such as diesel oil has a fuel adding means (fuel adding valve 25) for adding the fuel to a diesel catalyst 24 disposed to an exhaust system. The fuel added by the fuel adding means 25 functions as additive for NO x reduction or additive of increasing catalyst temperature in the diesel catalyst 24. Since the fuel containing soot or the like supplied to the engine body 7 of the diesel engine 1 lubricated with fuel such as diesel oil can be consumed early, the effect on a component of an injection system such as an injection pump and a fuel injection valve is mitigated.

摘要： PROBLEM TO BE SOLVED: To provide an engine control device capable of avoiding the start of an engine and damage to the engine in such states that a lubricant is frozen or insufficient and to provide a diesel engine lubricated with a fuel such as light oil.
SOLUTION: This engine control device 20 comprises a viscometer 21 detecting the viscosity of the fuel fed to an engine lubrication system 7 and a control part 22 determining whether the cranking of a starter 23 can be performed or not based on data acquired from the viscometer 21. When the viscosity of the fuel as the lubricant is found to be not proper based on the data acquired from the viscometer 21, the starter 23 is not cranked and the engine 1 is not started. Thus, damage to the engine lubrication system 7 can be avoided.

摘要： PROBLEM TO BE SOLVED: To improve in the lubricativeness of a needle by installing a filter which atomizes an oil mist being contained in gas fuel and diffuses it in a fuel passage, in this CNG engine in use of compressed natural gas(CNG). SOLUTION: Gas fuel to be forcibly fed to an injector 1 passes through a filter 40, flowing into a fuel passage 4, and then it is sprayed out of a nozzle hole 11 of a nozzle 10 with a needle 2 lifting. At this time, any foreign substances in the gas fuel is filtrated by this filter 40, and thereby such a possibility that these foreign substances might be bitten into space between the needle 2 and the nozzle 10 and the gas fuel leaked from the injector 1 is prevented from occurring. Most of CNG are transmorted in a gaseous state, and since a trace of oil is mixed in a process till being fed as the CNG, an oil mist in the gas fuel is atomized by the filter 40 and diffused in the fuel passage 4, whereby it is stuck to a peripheral surface slidingly contacting with a guide 30 of the needle 2 and a valve element part 21 colliding with a seat surface 12, improving their lubricativeness.

摘要： PURPOSE:To suppress the evaporation of lubricating oil, by introducing a small quantity of fuel into the lubricating oil during the operation of an engine so that the light substance content of the lubricating oil is increased and the temperature of the lubricating oil adhering to a cylinder is reduced by heat absorption due to the vaporization of the light substances in the lubricating oil. CONSTITUTION:A fuel injection pump 4, which acts in connection with the rotation of the crankshaft of an engine 1, comprises plungers 5 and barrels 6 for injection and another plunger 9 and another barrel 10 for fuel introduction. The number of the ejection plungers 5 and that of the ejection barrels 6 correspond to that of the cylinders of the engine 1. Fuel supplied under pressure by the action of the plunger 9 can be introduced into lubricating oil in a crankcase 2 through an introducing nozzle 11 provided in the crankcase. Since the fuel is introduced into the lubricating oil, the temperature of the lubricating oil adhering to a cylinder is reduced by heat absorption due to the vaporization of the light substances of the fuel to suppress the evaporation of the lubricating oil to diminish its consumption.
