Problems solved by technology
The traditional fuel consumption meter is relatively simple to measure the fuel consumption of gasoline engines with carburetors. However, with the increasingly stringent automobile emission regulations and the rapid progress of automotive electronics technology, the carburetors of gasoline engines have gradually been replaced by electronically controlled fuel injection systems (EF )I, the objects of fuel economy measurement of automobiles have all become electronically controlled injection engines, and electronically controlled injection engines need to deal with the return of excess fuel, making the measurement of fuel consumption complicated

Embodiment Construction
[0010] A new method for measuring automobile fuel consumption is mainly composed of a driving pulse width monitoring module, a controller, an engine injector, a calibrator and a fuel supply tank, and is characterized in that: the engine injector 3 is set in the driving pulse The input terminal of the width monitoring module 1, the driving pulse width monitoring module 1 is connected to the controller 2, the controller 2 is connected to the calibrator 4, the engine injector 3 is connected to the calibrator 4, and the calibrator 4 is connected to the fuel supply tank 5. Connected.
[0011] The controller 2 is mainly composed of a single-chip microcomputer, a pulse width-to-pulse number conversion circuit, a solenoid valve control circuit, and an oil level detector.
[0012] When the calibrator 4 is not working, the electric pump of the crude oil tank supplies oil to the engine; when the calibrator 4 is working, the electric pump in the calibrator supplies oil to the engine.

The invention discloses a new method for measuring automobile fuel consumption and belongs to the technical field of sensor detection. The new method mainly comprises a driving pulse width monitoringmodule, a controller, an engine injector, a calibrator and an oil supply tank, and is characterized in that the engine injector is arranged at an input end of the driving pulse width monitoring module, the driving pulse width monitoring module is connected with the controller, the controller is connected with the calibrator, the engine injector is connected with the calibrator, and the calibratoris connected with the oil supply tank. Through adoption of the method, signal lag is eliminated; with good dynamic characteristic, the method is especially superior in measurement of fuel consumptionunder a transient condition; and machining volume and processing accuracy are low, so that the cost is lowered greatly, and the method can be better promoted.
Description
Technical field [0001] The invention relates to a new method for measuring automobile fuel consumption, and belongs to the technical field of sensor detection. Background technique [0002] Fuel consumption is one of the main performances of a car. It is very important to accurately and quickly detect and evaluate the fuel consumption of a car. The fuel economy assessment specified in the relevant national standards uses a fuel consumption meter measurement method. . The traditional fuel consumption meter is relatively simple to measure the fuel consumption of the gasoline engine of the carburetor. However, with the increasingly stringent automobile emission regulations and the rapid progress of automobile electronic technology, the carburetor of the gasoline engine has gradually been controlled by the electronically controlled fuel injection system (EF ) Replaced by I, the objects of automobile fuel economy measurement have all become electronically controlled injection engines...
