Definitions

  • the present invention relates to a cleaning agent used by being added to a fuel in order to clean and remove deposits attached to a fuel injection system.
  • a diesel engine mounted on a truck, a construction machine, a fishing boat, a generator, or the like includes a piston that reciprocates and a cylinder that covers and surrounds the piston, and combustion formed by the piston and the cylinder. Air is supplied into a chamber (a chamber in which fuel is combusted), the air is compressed by a piston, and fuel is injected into the compressed and heated air to self-ignite.
  • an injection pump is indispensable for injecting fuel into a combustion chamber at a high pressure.
  • the types of injection pumps include a row type injection pump, a distribution type injection pump, and an independent type injection pump.
  • the fuel injection method includes a method of injecting fuel using these mechanical injection pumps.
  • many unit injector types and common rail types that perform electronically controlled injection have been adopted in place of these types of mechanical injection pumps, and the common rail type has become the mainstream.
  • the unit injector type is a fuel injection system that integrates a fuel injection nozzle called an injector and a plunger that pressurizes the fuel. Since there is no fuel supply pipe between the plunger and the nozzle, high-pressure fuel injection is realized by the plunger. it can.
  • the common rail type is a fuel injection method in which high-pressure fuel is stored in a long and narrow pipe called a common rail and is uniformly supplied to each injector connected to the pipe. In this common rail type, fuel is pressurized by a supply pump and reliably injected into the combustion chamber using an injector. The injection control is performed by the control unit.
  • Fuel is compressed in the supply pump. However, when air is mixed in the fuel for some reason, the air is adiabatically compressed, and the surrounding air becomes locally hot (local high temperature), which tends to generate unburned carbon. As a result, various additives are deposited and deposited and deposited inside the injector. In addition, the fuel contains foreign substances such as iron-based compounds, organic acids and salts thereof, and dust, and these foreign substances adhere and accumulate. These are called deposits, and if they adhere and accumulate in large quantities, they cause engine performance degradation and non-uniform injection.
  • This deposit / deposition is considered to be precipitated by a low temperature fluidity improver, a lubricity improver, etc. added to the fuel in the winter and their degradation products.
  • the fuel to which these are added for example, when a common rail system is used to inject the air generated from the supply pump and the air that has entered from the outside in the supply pump while being injected from the fuel supply pump under a high pressure condition.
  • various additives in the fuel are also thermally decomposed by raising the temperature to generate new deposits (see, for example, Patent Document 1).
  • a cleaning agent to be added to the fuel tank is commercially available, and the cleaning agent can be added to the fuel and cleaned and removed during the running operation.
  • Polybuteneamine, polyetheramine, N-alkyl-pyrrolidone and the like are known and currently used as components of a cleaning agent effective in cleaning and removing deposits.

  • the water-soluble amine compound include diethylamine and monoethanolamine.
  • polybuteneamine and polyalkenyl succinimide are polymer components, have good heat resistance, and have a problem of depositing themselves.
  • Polyetheramine and N-alkyl-pyrrolidone have detergency but not so high detergency. For this reason, in order to clean until no deposit can be visually confirmed, as described in Patent Document 1, a large amount such as several tens of weight% with respect to the fuel must be added. Such a large amount of addition has a problem in running performance, and since both of these are amines and contain nitrogen, there is a problem that NOx in the combustion exhaust gas increases.
  • O-ring swelling is preferable in that it fills the gaps between parts to a certain extent and improves the sealing force.
  • swelling above a certain level will cause cracks and increased hardness in the rubber, which will cause protrusions from the seal site.
