Description
Technical field
The utility model relates to the automotive fuel wastage detection range, relates to a kind of carbon balance method automotive fuel wastage tester specifically.
Background technology
At present, the world wide energy shortage, environmental pollution is more and more serious, and energy-saving and emission-reduction have become the fundamental state policy of China.The 46 of up-to-date " energy conservation " clearly stipulated: " the relevant Competent Authorities of Transport and Communications of State Council should strengthen the supervision and management to the detection of traffic operation car and boat fuel consumption." in order to strengthen the management of road transport automobile energy-saving consumption reduction; standard road transport vehicle dyestuff consumption vehicle vehicle parameter up to standard and configuration verification work, Ministry of Communications has promulgated " road transport fuel consumption in vehicles amount detects and administration Regulations for Supervision ", " operating passenger car fuel consumption limit value and measuring method ", " operation lorry Fuel Consumption limit value and measuring method ".
For management that the commerial vehicle Fuel Consumption is exercised supervision, just must take a kind of practicable detection method, accurately detect automotive fuel wastage, need easy and simple to handle simultaneously.At present, mainly contain the direct method of measurement and the indirect method of measurement two big classes for the detection method of automotive fuel wastage, the direct method of measurement comprises volumetric method and gravimetric method, and the indirect method of measurement comprises that mensuration is directly adopted in exhaust and based on the exhaustion dilution measurement method.
The direct method of measurement is the fuel feed system that fuel consumption meter is sealed in engine, vehicle loads at chassis dynamometer, travel situations on the simulating vehicle road, special-purpose automobile fuel consumption instrument (weight method or volumetric method) directly measures volume of fuel or the quality that automobile consumes in certain hour or the mileage, detects the fuel consumption per hundred kilometers of vehicle.Consuming instrument as piston type fuel is exactly a kind of volumeter.But because this method need consume fuel in the fuel feed system that instrument seals in motor car engine, have problems: 1. safety problem because gasoline is volatile, can pollute and disaster hidden-trouble; 2. influence the measuring accuracy of engine operate as normal and fuel consumption, can have influence on engine fuel supply after fuel consumption meter seals in the oil circuit, easily produce bubble, leakage etc.; 3. the installation of fuel consumption meter connects very inconveniently, and engine for automobile does not generally allow the user to tear oil circuit open now, and must understand fully the oil circuit of different automobile types during dismounting, and the aperture of connecting line and length may not match yet, and trouble more is installed when return line; 4. install and the measuring process time longer, especially automatically controlled fuel feed system is brought difficulty to the installation of fuel consumption meter, and vehicle is brought infringement.
The indirect method of measurement is to utilize before motor car engine fuel and the air burning and law of conservation of mass that the carbonaceous amount after the burning equates is calculated the Fuel Consumption of automobile.Wherein, exhaust is directly adopted mensuration and is directly measured the engine exhaust flow by exhaust flow-meter, directly adopts by exhaust and analyzes CO in the exhaust
2, CO, HC actual concentrations.But this method still has the following disadvantages: 1. contain a large amount of water in the exhaust, condensation can take place in the gas sample in course of conveying, and analyser is measured and also will be anhydrated; 2. exhaust exists pneumatic fluctuation, temperature very high, causes to be difficult to the accurate measurement extraction flow, thereby influences the accuracy of measurement result; 3. the extraction flow variation range of Under Different Work Condition of Engine is very big, and the range ratio of conventional flowmeter is difficult to satisfy; 4. sample connection and gas outlet need be realized sealed attachment, but because automobile exhaust pipe varies, and simultaneous temperature is higher, quick and reliable sealed attachment is very difficult; 5. measuring error is bigger, is difficult to measuring error control in 5%.
The exhaustion dilution measurement method is that the flow carbonaceous component concentration of exhaust is measured in exhaust and air dilution back, since simple to operate, favored.Developed country such as the U.S., Japan has just carried out a large amount of research to the automobile fuel consumption detection system based on the carbon balance method theory at the mid-1970s, but (being about to auto exhaust all collects all to adopt constant volume samapling, through a series of processing, measure carbon amount wherein), and some achievements and test figure have been obtained, the result shows that it is fully feasible that this method is surveyed automobile fuel consumption, and can carry out when detecting the auto exhaust discharging.But this detection system equipment is huge, complicated, expensive, and can't realize fast detecting.Adopting this detection system to carry out the oil consumption detection only is confined to be difficult to widespread use in practice in the laboratory.At home, because technical backwardness, detection to vehicle fuel economy is paid attention to later, Ministry of Communications just issued and implemented rules-" the motor transport service combination property measuring station management method " that relates to the fuel consumption in vehicles detection up on October 1st, 1991, and the measuring method that regulation adopts also is volumetric method and gravimetric method.Surveying oil consumption with the carbon balance method principle does not draw attention.Along with electronic gasoline injection technology, the automatically controlled fuel feed system of diesel oil have begun to popularize in motor car engine, press for realization vehicle fuel economy is realized not understanding bulk measurement and evaluation.The fuel consumption of traditional gravimetric method, the direct measured automobiles of volumetric method can not be satisfied the demand.Therefore, research automotive performance detection line fuel consumption test new method, the testing apparatus that exploitation is relevant realizes that the quick measurement of automobile fuel consumption is very urgent and necessary.
