Definitions
- the present invention relates to a diesel engine system comprising a diesel engine provided with a crankcase comprising a crankcase lubricating oil, an air intake, an air compressor, an effluent turbine and an after cooler.
- Diesel engines provided with a crankcase, crankcase lubricating oil, an air intake, an air compressor, an effluent turbine and an after cooler are described in US-A-6102013.
- a problem with crankcase lubricating oils is that they tend to escape from the crankcase with the so-called blow by gases. Rather than vent these blow by gas to the atmosphere, it is preferred to re-circulate this gas/lubricant mixture to the engine. This recirculation is performed in some engines by injecting the blow by gasses to the engine's air intake system such that the lubricant is combusted in the piston chambers.
- Diesel engine system comprising a diesel engine provided with a crankcase comprising a crankcase lubricating oil, an air intake, an air compressor, an effluent turbine, an after cooler, and a blow by gas recirculation system comprising means to recirculate the blow-by gas to the air intake, wherein the crankcase lubricating oil comprises an iso-paraffinic base oil having a saturates content of greater than 99 wt% and a viscosity index of greater than 120, a performance additive package system, and a viscosity modifier additive.
- crankcase lubricating oil preferably has a kinematic viscosity at 100 0 C of between 9.3 and
- the crankcase lubricating oil preferably comprises a blend of two iso-paraffinic base oils having each a saturates content of greater than 99 wt% and a viscosity index of greater than 120 and preferably between 120 and 150.
- the first base oil preferably has a kinematic viscosity at 100 0 C of between 3 and 6 cSt.
- the second iso-paraffinic base oil preferably has a saturates content of greater than 99 wt%, a viscosity index of greater than 135 and a kinematic viscosity at 100 0 C of greater than 7 cSt.
- the first iso-paraffinic base oil comprises paraffin compounds and less than 15 wt% naphthenic compounds, wherein the naphthenic compounds are of the general formula:
- the second iso-paraffinic base oil comprises paraffin compounds and less than 15 wt% naphthenic compounds, wherein the naphthenic compounds are of the general formula:
- the weight ratio between the first and the second base oil will depend on the target lubricating oil grade and on the viscometric properties of the starting base oils. Generally the majority, suitably more than 50 wt% of the oil formulation will be comprised of the second base oil.
- the viscosity modifier additive may be the standard types such as olefin copolymers or hydrogenated isoprene or hydrogenated isoprene copolymers. Examples are Infineum SV-151, which is a hydrogenated isoprene-styrene co-polymer, as obtainable from Infineum Additives, Milton Hill, U.K.
- the viscosity modifier additive is preferably present in the oil formulation in a content of between 6 and 16 wt% more preferably between 6 and 10 wt%. Applicant found that when the base oils described above are used, less of the viscosity modifier additive is required than when the state of the art mineral derived Group III base oils are used to arrive at the same viscometric properties of the resulting oil formulation.
- the performance additive package system present in the the crankcase lubricating oil comprise dispersants, detergents, extreme pressure/antiwear additives, antioxidants, pour point depressants, demulsifiers, corrosion inhibitors, rust inhibitors, antistaining additives, friction modifiers. Specific examples of such additives are described in for example Kirk-Othmer Encyclopedia of Chemical Technology, third edition, volume 14, pages 477-526.
- the anti-wear additive is a zinc dialkyl dithiophosphate .
- the dispersant is an ashless dispersant, for example polybutylene succinimide polyamines or Mannic base type dispersants.
- the detergent is an over-based metallic detergent, for example the phosphonate, sulfonate, phenolate or salicylate types as described in the above referred to General Textbook.
- the antioxidant is a hindered phenolic or aminic compound, for example alkylated or styrenated diphenylamines or ionol derived hindered phenols. Examples of suitable antifoaming agents are polydimethylsiloxanes and polyethylene glycol ethers and esters .
- the content of the performance additive package in the crankcase lubricating oil is suitably between 4 and 20 wt% and more preferably between 10 and 16 wt%.
- the performance additive packages are commercially available from many vendors and typically have the following composition comprising: Dispersant additive between 40 and 70 wt%, Over-based plus non-over based detergent additives between 15 and 50 wt%, Diluent Oil between 30 and 50 wt%, Anti wear additive between 3 and 8 wt%.
- crankcase lubricating oil preferably has a dynamic viscosity at -25 0 C of between 6500 and ⁇ 7000 cP, a mini rotary viscometer test value of below 60000 cP at -30 0 C. In the context of the present invention the following test methods are to be applied.
- the present invention further relates to the use of a lubricating oil as descriebd herein-before, comprising an iso-paraffinic base oil having a saturates content of greater than 99 wt% and a viscosity index of greater than 120, a performance additive package system, and a viscosity modifier additive, for the reduction of deposits in a Diesel engine system comprising a diesel engine provided with a crankcase comprising a crankcase lubricating oil, an air intake, an air compressor, an effluent turbine, an after cooler, and a blow by gas recirculation system comprising means to recirculate the blow-by gas to the air intake.
- a lubricating oil as descriebd herein-before, comprising an iso-paraffinic base oil having a saturates content of greater than 99 wt% and a viscosity index of greater than 120
- a performance additive package system comprising a viscosity modifier additive
- the present invention further relates to a process for operating a Diesel engine system comprising a diesel engine provided with a crankcase comprising a crankcase lubricating oil, an air intake, an air compressor, an effluent turbine, an after cooler, and a blow by gas recirculation system comprising means to recirculate the blow-by gas to the air intake, wherein the crankcase lubricating oil comprises an iso-paraffinic base oil having a saturates content of greater than 99 wt% and a viscosity index of greater than 120, a performance additive package system, and a viscosity modifier additive .
- Figure 1 illustrates a preferred diesel engine system according to the present invention.
- Figure 1 comprises an air intake (1), an air intake filter (2), an air compressor (3), a conduit (4) for compressed air, an after cooler (5) , an inlet manifold (7), a crankcase (8), provided with cylinders (9) and crankcase oil (10) present in the crankcase (8).
- Conduit means (11) fluidly connects the cylinders (9) to an effluent turbine (14) .
- effluent turbine (14) Through conduit (11) exhaust gases flow.
- Effluent turbine (14) runs in line with the air compressor (3) as shown.
- the exhaust gases pass an exhaust silencer (15) fluidly connected to an exhaust (16) .
- the diesel engine system is provided with means (12) to recirculated part of the exhaust gasses to the cylinders.
- an exhaust flow control valve (13) and a exhaust gas recirculation cooler (17) is present.
- transport means (18) are present to direct the blow-by gases to the air flow just upstream the air compressor (3) .
- Example 1 preparation of the base oils and characterization
- the above distillate also referred to as waxy raffinate
- a dewaxing catalyst consisting of 0.7 wt% platinum, 25 wt% ZSM-12 and a silica binder.
- the effluent was distilled and a fraction boiling above 390 0 C was obtained having the properties of the first base oil of Table 2.
- Part of the first base oil was further distilled to isolate a fraction boiling above 460 0 C (cut off temperature) to obtain the second iso-paraffinic base oil of Table 2.
- the remaining oil boiling below 460 0 C had a kinematic viscosity at 100 0 C of 4 cSt.
- the content of the naphthenic compounds was performed using the FIMS method as described in more detail on pages 27 and 28 of WO-A-2005/000999. Measurement of the percentage carbon in the branches
- the starting point is a GASPE CH3 subspectrum, which is obtained by addition of a CSE spectrum (standard spin echo) to a 1/J GASPE (gated acquisition spin echo) .
- CSE spectrum standard spin echo
- 1/J GASPE gated acquisition spin echo
- CH3's as being the signals to low frequency of 25 ppm chemical shift (referenced against TMS) .
- This subspectrum is then integrated to give quantitative values for the various different CH3 signals.
- CH3 signals can be specifically identified, but in some cases assignment is less clear cut and certain assumptions have to be made as outlined below. Calculation of Methyl branch content a number of signals can be assigned to methyl branches.
- R alkyl group
- the observed signal is for the terminal CH3, but there are two corresponding methyl branches. Therefore the integral value of these signals needs to be doubled, (the signals for the two methyl branches are not counted independently) .
- the CH3 signal can be classed as termination of the main chain and discounted as being part of the ethyl branch content. (The corresponding signal for the methyl branch is observed at 19.3 ppm and is therefore already being included in the methyl branch content) .
- a signal at 10.9 ppm can be assigned as a pendant methyl of the general type:
- a smaller signal at 14.7ppm may be due to C3 branches .
- a second smaller signal at 14.5 ppm can be assigned to 4-methy structures, i.e.
- the major signal in this region is at 14.1 ppm and tends to be one of the most intense signals in the spectrum. This can be assigned to any CH3 without a branch within 4 carbons i.e.
- a 10W40 crankcase engine oil was formulated using the base oils from Table 2 wherein the final formulation comprised of 3 wt% of the first base oil, 67.9 wt% of the second base oil, 8.9 wt% of a commercially available viscosity modifier additive and 20.2 wt% of a standard additive package not containing a viscosity modifier.
- This crankcase oil formulation was subjected to the MTU Deposit test, a standard test method described (DIN 51535), part of the MTU Engine Oils for Diesel Engines specification MTL 5044 (January 2004) .
- the MTU deposit test value is 105 mgs deposits.
- a 10W40 crankcase oil formulation having the same kinematic viscosity at 100 0 C as in Example 1 was formulated using two mineral derived base oils having the properties listed in Table 3.
- the final formulation comprised of 24.5 wt% XHVI-5 and 43.9 wt% XHVI-8.
- the oil further contained 11.4 wt% of the viscosity modifier additive and 20.2 wt% of a standard additive package not containing a viscosity modifier.
- MTU Deposit test of Example 1 resulting in a MTU deposit test value of 141 mgs deposits.
- the lower MTU test value of example 1 as compared to this experiment is a significant indicator that less deposits will form in the air intake system or in the optional air cooler.
