The present invention and the supporting special fuel delivery system of the clean fuel composition of ring, on the transport pipe between fuel reservoir output terminal and the diesel engine fuel input terminus, and on the pipeline between diesel engine oil return output terminal and the fuel reservoir oil return input terminus, each installs a cover cooling system, and wherein the type of cooling of cooling system is air-cooled or water-cooled or oil cooling.
Above-mentioned fuel delivery system, connect to form the loop by oil port, liquid level display, used oil pipe, oil return condenser, air-fuel ratio regulating mechanism, diesel engine, oil-feed condenser, oil inlet pipe, transfer pump and fuel tank, wherein diesel engine is connected with air-fuel ratio regulating mechanism, oil return condenser and oil-feed condenser formation respectively, the oil-feed condenser is connected with fuel tank through transfer pump, and the oil return condenser is connected with the fuel tank formation through used oil pipe.
The present invention has following advantage:
1, because the clean fuel normal temperature of ring that uses is liquid state down, and supply of fuel needn't increase vapourizing unit and breathing process control corresponding system, simplifies repacking greatly and reduce improvement cost.
2, can utilize former diesel oil fuel supply system to carry out the regulation and control of air-fuel ratio and fuel injection characteristic, obtain better working process.
3, the main ingredient pentane of its composition is the byproduct of refinery in producing finished product processes such as gasoline and diesel oil, i.e. C5 fraction, and raw material is easy to get.
Though 4, common pentane can be used as fuel, undesirable without the effect that any processing is used on diesel engine, mainly be that the compression ignite temperature is higher, cause incomplete combustion, cause that the oil engine oil consumption increases, dynamic performance descends.In addition, the viscosity of pentane is too little, and lubricity is bad, causes oil engine mechanical wear big, therefore inapplicable diesel engine.The clean fuel composition of ring of the present invention has successfully been selected effective fuel catalytic auxiliary agent for use, has solved above problem, and just must the clean fuel of this ring need not to transform the diesel engine structure can use, and has reduced production cost.
5, compare with the incomparable ultra-low-sulphur diesel of existing environment-friendly type in the world, its black smoke concentration reduces by 68%, oxynitride (NO
X) reduce by 11%, compare with general diesel oil, its black smoke concentration reduces by 78%, learn through dissimilar diesel oil and the actual test of use, general black smoke concentration (FSN) is all less than 2, and some type black diesel smoke concentration (FSN) is a kind of rare eco-friendly power source less than 1.
6, the production cost of the clean fuel of ring and diesel oil compare, and its cost slightly reduces.
7, in the general diesel engine, be equipped with return oil system, its diesel oil oil return portion temperature scope is at 40-90 ℃.When using the clean fuel of ring of the present invention, because main ingredient is the vaporization temperature lower (36 ℃) of pentane in the fuel, therefore, with existing diesel engine return oil system, " vapour lock " phenomenon can appear, cause combustion engine powered degradation, even " dead fire ".The present invention has designed special-purpose assorted fuel delivery circuit system, has guaranteed that the clean fuel of ring is able to flameholding, safety, continuous operation on diesel engine, and its dynamic performance and diesel oil are approaching, can effectively solve the phenomenon of " vapour lock " and " dead fiery ".
