Description

Duplex matter combined cycle diesel engine

The present invention relates to the thermal machine technical field, is the improvement to available engine, is applicable to petrol engine, diesel engine and gas turbine.

The thermal machine kind is many, uses extensively, and the national economic development is played an important role.As everyone knows, motor is by means of the heat of doing work of the working medium with certain potential energy, can not directly transfer function to.And the motor that generally uses at present, no matter be the opening combustion or the combustion of remaining silent all be the motor of single working medium working system, its shortcoming is that efficient is low, the thermal efficiency of various motors is all below 50%, as petrol engine is 27-30%, the higher diesel engine of efficient is 40-42% only, and steamer is lower, only is 8-10%.Inefficient reason is only to do work by single working medium, and dynamic property is poor, as diesel engine: in the starting stage of expansion stroke, fuel very fast burn burns down complete, after this, energy no longer discharges, and working medium no longer increases, cause peak pressure endurance weak point in the cylinder, and along with the very fast decline of the rapid increase-volume pressure of cylinder, moment of torsion is very little, therefore, it all is very difficult that efficient improves one of percentage, and this is a difficult problem that does not have solution for a long time.Section's technology personnel manage remain silent combustion and opening burning type engine are combined in recent years, realize combined cycle, though can utilize the after-heat and the discarded combustion gas potential energy of opening motor of the motor of remaining silent like this, save energy consumption, raise the efficiency, but two machineries combine, equipment is many, volume is big, combination is complicated, be difficult to generally apply, be only limited to the seat stand machine applications of large-scale thermal power machine, then can't solve for the Transport Machinery and the engineering machinery of a large amount of high energy consumption poor efficiency.

The objective of the invention is to develop a kind of rational in infrastructure, practical, can be with the acting of two kinds of working medium, the efficient height, dynamic property is good, saves the duplexing matter combined cycle diesel engine of the energy.

For achieving the above object, the present invention has adopted following technological scheme: comprise bent axle, connecting rod, the crankshaft ﹠ connecting that piston and cylinder body are formed, camshaft, valve and advancing, the distribution device that outlet pipe is formed, plunger pump, the fuel supply system that high-voltage tube and sprayer are formed, centrifugal pump, the cooling system that cooling jacket and radiator of water tank are formed, generator, the electrical system that storage battery and transformer are formed, filter cleaner, the lubrication system that oil pump and oil sump are formed, it is characterized in that having adopted water as second working medium, the second working medium make-up system has been installed, its structure is: with the second working medium make-up system and cooling system gang, be provided with water storage box, the outlet of water storage box, one the tunnel links to each other with radiator of water tank, another road links to each other with I level filter with cooling jacket through centrifugal water pump, gear pump and heat exchanger and II level are arranged thereafter, III level filter links to each other, again the back and triple valve, pressure-limit valve, plunger pump, the high-voltage tube heat exchanger links to each other with sprayer, sprayer leads to the vaporium on cylinder top, and each cylinder all has a vaporium and spray zero device.

Diesel engine of the present invention is that two kinds of working medium are applied in the motor, carry out combined cycle, both finished and obtained the Sai Er circulation, finish the Lang Ken circulation again, this has not only utilized the burning potential energy of the combustion engine of remaining silent, and its waste heat also can convert second working-medium water to steam potential energy and sends into the firing chamber, can be little to solve the cylinder combustion imposing manner, long-term insurmountable difficult problems such as the maximum pressure endurance is short, improved the dynamic property of motor, efficient can be brought up to more than the 50-60%, and can be according to various vehicles to moment of torsion, the time for spraying of second working medium is controlled in the different requirements of rotating speed.
