Definitions

  • the valve member for example with a needle tip, closes and opens access to a nozzle aperture according to a precise timing.
  • a number of injectors are arranged in a circle around the cylinder in a plane perpendicular to a cylinder axis and each injector comprises one or more nozzle apertures at the tip for delivering lubricant jets or sprays into the cylinder from each injector.
  • Examples of lubricant injectors in marine engines are disclosed in international patent applications WO02/35068, WO2004/038189, WO2005/124112, WO2012/126480, WO2012/126473, and WO2014/048438.

  • the valve member comprises a stem with a second surface, the second surface being provided slidably abutting the first surface in order for the stem being recipro- cally guided by the plain bearing along a contact region between the stem and the plain bearing.
  • the valve member comprises a valve needle in coaxial longitudinal extension of the stem.
  • the valve needle comprises a needle tip that is closing the nozzle when abutting a cooperating valve seat in the nozzle tip.
  • the princi- pie of the injector is as disclosed in WO02/35068, WO2004/038189 or WO2005/124212 for a single nozzle aperture or as disclosed in WO2012/126480 for multiple nozzle apertures.
  • the injector is similar to the one disclosed in WO2012/126473. Other examples are disclosed in the prior art.
  • a general improvement has been achieved by a high hardness of not only the surface of the stem but also by providing the plain bearing with a high hardness. For this reason, it is advantageous to surface-harden both the first and the second surface.
  • the stem is provided in a very hard material from the onset, for example ce- ramies, and the surface of the bearing, which is the first surface, is surface-hardened in order to provide hard surfaces that are abutting each other along a contact region, where the stem is sliding in the plain bearing.
  • a general improvement has been achieved by a high hardness of the cylindrical sealing head as well as a high hardness of the cavity wall along the contact region between the surface of the cavity wall, which is the first surface, and the surface of the cylindrical sealing head, which is the second surface. For this reason, it is advanta- geous to surface-harden both the first and the second surface.
  • the cylindrical sealing head of the valve member is provided in a very hard material from the onset, for example ceramics, and the surface of the cavity wall is surface-hardened in order to provide hard surfaces that are abutting each other along the contact region, where the cylindrical sealing head is sliding in the cylindrical cavity.
  • surface-hardening of such surfaces improves uniform long term performance among a plurality of identical lubrication oil injectors for a large slow-running two- stroke engine, especially marine engines or engines in power plants, for example burning diesel or gas. Hardening is performed during production of the injectors for the first surface and the second surface or for the valve seat or for the first and second surface as well as the valve seat.
  • the needle tip is hardened or provided in a hard material that corresponds to the hardness of hardened material.
  • a useful material that is surface-hardened for the purpose herein is carbon steel or low alloy steel.
  • a useful is steel of the type ETG® 88.
  • Such steel comprises 0.42-0.48% carbon, 0.10-0.30% silicon, 1.35-1.65% Manganese, less than 0.04% phosphorous and 0.24-0.33% sulphur.
  • the steel name is a trademark, the steel has a content of chemical elements and has physical properties that remain unchanged according to readily available data sheets.
  • a further alternative is nitrocarburizing, which is similar to gas nitriding but where carbon gas is added.
  • the layer thickness of the hardened surface is influenced by the gas compo- sition during the process.
  • a further process in the prior art is gaseous ferritic nitrocarburizing, which is also known under the trade name Corr-I-Dur® and various other trade names.
  • FIG. 1 illustrates a cylinder lubrication system in a large slow-running two-stroke engine, for example marine diesel engine;
  • FIG. 2 a), b), and c) illustrate three types of lubrication oil injectors
  • FIG. 3 shows pressure measurements for injectors with a) a hardened stem and b) a hardened stem and hardened plain bearing;
  • Each of the injectors 4 has a nozzle 5 from which a spray of small droplets 7 is ejected under high pressure into the cylinder.
  • the swirl 9 of the scavenging air in the cylinder 1 presses the spray 8 against the cylinder liner 2 such that an even distribution of lu- brication oil on the cylinder liner 2 is achieved.
  • This lubrication system is known in the field as Swirl Injection Principle, SIP, although also other principles are envisaged in connection with the improved injectors, for example injectors that have jets directed towards the cylinder liner.
  • the cylinder liner is provided with free cuts 6 for providing adequate space for the spray or jet from the injector.
  • FIG. 2a illustrates a first type 4a of lubrication oil injector.
  • the generalised principle of the injector is similar to the ones disclosed in WO02/35068, WO2004/038189 or WO2005/124212 for a single nozzle aperture or as disclosed in WO2012/126480 for multiple nozzle apertures. These references also provide additional technical details as well as explanations to the functioning of the injectors presented here, which are not repeated here, for convenience.
  • the injector 4a comprises an injector housing 12 having a nozzle tip 13 which is integral with the injector housing 12 at one end.
  • a nozzle 14 with a nozzle aperture 14' is provided in the nozzle tip 13 for ejection of lubrication oil.
  • FIG. 2c illustrates a third type 4c of lubrication oil injector.
  • the generalised principle of the injector is similar to the one disclosed in WO2012/126473. This reference also provides additional technical details as well as explanations to the functioning of the injectors presented here, which are not repeated here, for convenience.
  • the valve member 16 comprises a valve needle 18 to which there is fastened a sealing ball member 28 as part of a needle tip 22, which in closed valve conditions is pressed against the seat valve 19 for closure of the duct 20 and which in open valve conditions is offset from the seat 19 a distance to allow lubrication oil to pass from the inner cavity IS pass the needle tip 22 with the ball 28 and into the duct 20 and out of the nozzle aperture 14'.
  • the inner cavity IS is sealed backwards towards the remaining parts inside the injector housing 12.
  • the valve seat 19 comprises a hardened surface at the sealing contact region 30 be- tween the valve seat 19 and the ball member 28 in order to prolong lifetime against wear from the repeated hits of the ball member 28.
  • a hardened surface is provided on the surface of the stem 17 and on the surface of the plain bearing 23 such that two hardened surfaces are sliding along each other at the contact region 24.
  • the surfaces were hardened by austenitic carbonitriding, which involves carbon and nitrogen in the surface of the hardened component.
  • the carbonitriding was performed at a temperature of about 850 °C in a gas atmosphere to which were added between 0.5 and 0.8 % carbon and 0.2-0.4 % ( ⁇ 5 %) nitrogen to the surface of carbon steel or low alloy steel. After the diffusion, the components were immediately submerged into oil.
  • the typical hardening depth was not above 0.7 mm and did not solely depend on the carbonitriding depth but also on the hardening temperature and the time until cooling. Subsequent tempering at a temperature of 150-200 °C can be used for larger hardening depth and reduced brittleness.
  • FIG. 4a shows a table with indications for injector performance.
