Description
Technical field
The utility model relates to a kind of diesel engine combustion alcohol system, particularly relates to a kind of diesel engine based on cooler for recycled exhaust gas gasified methanol combustion alcohol system.
Background technique
Energy-saving and emission-reduction are the important R&D directions of current vehicular engine one, the energy-conservation consumption namely reducing energy, and reducing discharging is then reduce the noxious emission in motor exhaust.Diesel oil has higher Economy than gasoline makes diesel engine increase gradually at vehicular engine proportion.Along with domestic and international to the issue of engine exhaust emission regulation, implement the requirement of emission from vehicles stricter.In order to meet strict Abgasgesetz, diesel engine significantly must reduce the discharge of predominant emissions NOx and particulate matter.
In the dirty mode of Reduction for Diesel Engines, there is a kind of new way: Diesel Methanol fuel combination replaces diesel oil as the fuel of diesel engine, effectively can to reduce in tail gas the harmful matters such as NOx.But the character of Diesel Methanol emulsified liquid is unstable, is long placed in easy layering, be unfavorable for storing, and the poor stability of burning.
Summary of the invention
Technical problem to be solved in the utility model is to provide the good combustion of the diesel engine based on the cooler for recycled exhaust gas gasified methanol alcohol system of a kind of combustion stability.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of combustion of the diesel engine based on cooler for recycled exhaust gas gasified methanol alcohol system, it is characterized in that comprising diesel engine, pressurized machine, methyl alcohol supplier, first intercooler and the second intercooler, described diesel engine is provided with exhaust steam passage, first passage is provided with between described exhaust steam passage and the first intercooler, methyl alcohol supplier is communicated with first passage, second channel is provided with between the first described intercooler and the second intercooler, third channel is provided with between second intercooler and diesel engine, an inlet opening of pressurized machine is communicated with exhaust steam passage, another inlet opening of pressurized machine is communicated with second channel.
Described methyl alcohol supplier comprises the methanol tank be mutually arranged on successively in methanol pipeline, goes out alcohol valve, methyl alcohol metering
Pump, one-way valve and spray alcohol device, spray alcohol device is positioned at first passage.
First pipeline is provided with air valve.
The first described intercooler is provided with coolant outlet, the first temperature transducer and frequency modulation water pump.
Differential pressure pickup is provided with between described first passage and second channel.
Described diesel engine is provided with speed probe.
Described pressurized machine is provided with suction tude.
Also comprise central monitoring system, described speed probe is connected with central monitoring system, described frequency modulation water pump with
Central monitoring system connects, and described methyl alcohol metering pump is connected with central monitoring system, described air valve and central authorities
Supervisory system connects, and described differential pressure pickup is connected with central monitoring system.
Compared with prior art, the utility model has the advantages that and spray into methyl alcohol at outside cycle gas loop intake duct, utilize the heat vaporize liquid methyl alcohol of waste gas, the methanol steam after vaporization is together mixed in cylinder of diesel engine along with tail gas.Methyl alcohol can also play the effect of oxygenation, improves waste gas circulation utilization ratio, reduces discharge amount of exhaust gas simultaneously, the hydrocarbons content in tail gas is reduced.And methyl alcohol is owing to having the higher latent heat of vaporization, absorbs heat when vaporizing and forming mixed gas, effectively reduce intake temperature, improve volumetric efficiency, the generation of NOx can be reduced to a certain extent.The structure composition of this device can be divided into three parts: signal acquiring system, signal processing system, add alcohol system.
1, signal acquiring system: this subtense angle mainly gathers the signals such as relevant rotating speed, pressure, temperature, for system processing system provides processing signals.This system comprises: the speed probe on crankshaft of diesel engine, the temperature transducer on outlet pipe, be arranged on the pressure transducer in EGR (EGR) system, the temperature transducer in suction tude composition, the temperature transducer on cooler.2, signal processing system: the calculated signals process that this subtense angle gathers signal acquiring system, changes the control data and EGR (EGR) cooling system data that add alcohol system into, completes the output adding alcohol and cooling data.This system is the ECU system of the original paper compositions such as microcomputer chip.3, alcohol system is added: what this system mainly realized whole system adds alcohol function, comprises two subtense angles and adds alcohol system, cooling system.Add alcohol system to comprise EGR valve, spray alcohol device, one-way valve, methyl alcohol metering mechanism, go out alcohol valve, methanol tank; Cooling system comprises: EGR intercooler, frequency modulation water pump.The working principle of this system: this covering device collects the signal such as rotating speed, delivery temperature, chiller temperature, EGR intake and exhaust air pressure of diesel engine by signal acquiring system, be converted into by the computing of information processing the alcohol control measure that adds adding alcohol system and add appropriate methyl alcohol according to for system, simultaneously for preventing tail gas overheated (reduction combustion performance) and excessively cold (methyl alcohol liquefaction), control the cooling effect of cooler for recycled exhaust gas water pump, realize the perfect adaptation of system.
The technical feature of this system is that this system can realize engine dual-fuel burning, and spray alcohol control accuracy is high, mixes the features such as alcohol rate is large.Contribute to the use of oil substitute fuel, and engine exhaust minimum discharge can be realized, be conducive to China environmental protection.
