Device and method for detecting real-time oil consumption of engine

Abstract

The invention discloses a device and a method for detecting the real-time oil consumption of an engine. The device comprises an oil inlet 1, an oil outlet 6, an oil return port 7, an oil suction pump 2, an oil tube 3, an oil measurement sensor 10, a solenoid valve 4, a buffer room 5, a return oil processing device 8 and a controller 9, and can detect the real-time oil consumption of the engine, the oil consumption accumulated in the operation zone, the oil consumption accumulated in the historical time period and the total accumulated oil consumption.

Description

technical field [0001] The invention relates to an engine real-time fuel consumption detection device and a detection method thereof. The detection device and detection method can detect real-time fuel consumption, accumulated fuel consumption in operating intervals, accumulated fuel consumption in historical time periods and total accumulated fuel consumption of the engine in real time. Background technique [0002] With the rapid development of my country's automobile industry, especially the market demand for public transport, passenger transport, logistics, and engineering vehicles continues to expand, people pay more and more attention to vehicle management, especially vehicle fuel consumption statistics management. However, due to the particularity of the engine's fuel supply system and the complex changes in the engine's working conditions, the vehicle's real-time fuel consumption detection device must not only achieve high accuracy within a wide measurement range, but...

AI Technical Summary

Problems solved by technology

This type of real-time fuel consumption detection device has the following problems: 1. Due to the continuity of the fuel supply system, the flow sensor cannot completely isolate the high-frequency pulsation of the oil return pipeline, and the system often works in an unsteady state, which causes measurement errors and affects measurement accuracy; 2. With the use time of the real-time fuel consumption detector, the metering element of the flow sensor is gradually worn out, and the metering coefficient changes, which reduces the measurement accuracy; 3. The flow sensor needs a certain opening pressure to start working normally, so this type of real-time fuel consumption The detector is prone to poor fuel supply or low measurement accuracy when the flow rate is low. In addition, it also produces fuel supply resistance in the fuel supply system during its use; 4. This type of real-time fuel consumption detector has high requirements on fuel quality. Generally, it is necessary to add a high-precision filter to the fuel supply system, which will increase the maintenance cost of the fuel supply system. Otherwise, the flow sensor will not work properly due to the entry of impurities, and even cause the flow sensor to be stuck and the engine to stall.
