[evaluation method]
Diesel engine use industry diesel engine with direct injection.
In this diesel engine, as being subjected to fuel lubricity to influence bigger position, it in the jet-type fuel-injection pump vibration section between plunger and the plunger barrel, in the distribution type fuel-injection pump, vibration section between the vibration section between above-mentioned plunger and the plunger barrel and face cam (face cam) and the roller includes the needle-valve of total Fuelinjection nozzle and the vibration section between the main body in either case.
The state of wear at these positions has bigger influence to fuel injection performance, and when wearing and tearing are worth when big than certain, it is bad that fuel injection performance becomes, and mechanical property is damaged, and machinery can not turn round sometimes under abominable situation.
Therefore, in this evaluation, compare with the existing fuel oil condition that makes by the DME monomer of employing (comparative example 1), under the fuel oil condition of embodiment 1 in adopting the scope of the invention, in fact by using New-type fuel squirt pump machine operation 200 hours, in these vibration sections, being representative between the most serious plunger of vibration condition and the plunger barrel, as content shown in Figure 1, each external diameter (dp1) and internal diameter (db) are measured, abrasion loss is compared evaluation.In addition, relatively the fuel injection top pressure is estimated the variation of fuel injection performance.
At this, under the situation for DME, can estimate (aggressive) wearing and tearing that come into force that throw into question in the utmost point short period of time.Therefore, setting runtime at this is 200 hours.In this time, do not have problems, as long as can judge and keep equal conditions, even thousands of to tens thousand of hours can not produce this problem for a long time yet.
[evaluation result]

The gap increases expression plunger outside or the plunger barrel internal surface is worn, and in addition, the fuel injection top pressure causes compressed fuel to leak because the gap increases, and therefore demonstrates the change situation of (becoming bad) of fuel injection performance.
From Fig. 2 (a) and result (b) as can be known, using under the fuel oil condition that forms by comparative example 1DME monomer, form above allowing the gap of limit more than 10 microns in the utmost point short period of time, because wearing and tearing diversity ground carries out, jet performance has problems as a result, but under the fuel oil condition of the embodiment 1 that adopts the scope of the invention, in the early stage because running-in produces a little loss, but move closer to the gap that allows in the limit along with the time, can judge that it suppresses the carrying out of wearing and tearing, and can keep jet performance.
The wearing and tearing that show in this example allow 10 microns not necessarily general values of limit, but the value that changes with mechanical kind, but when the gap at least more than 10 microns the time, sometimes jet performance is caused obstacle, thus with it as a case representation.
In addition, being under the fuel oil condition that forms of the DME monomer by comparative example 1, can obviously observe and produce vertically scratch on the plunger surface, and under the fuel oil condition of the embodiment 1 that adopts the scope of the invention, can estimate affirmation and not produce vertical scratch.
Therefore, as can be known by using oil fuel as the embodiment 1 of the scope of the invention, the wear phenomenon of the fuel injection device that produces under the fuel oil condition that can prevent to adopt the DME monomer by comparative example 1 to form, no problem in practicality can be guaranteed its reliability.
At this, being example between plunger and the plunger barrel, shown its result, but between face cam and the roller and the needle-valve of Fuelinjection nozzle and intersubjective vibration section in the distribution type fuel-injection pump, also there is difference in its transformation period, but can confirm that there is same relation in abrasion loss, can guarantee oilness equally by oil fuel of the present invention.
