A fuel controllable adjustment device and method for heavy vehicles

Abstract

The invention discloses a fuel controllability adjusting device used for heavy vehicles. According to the device, an inflow fuel amount sensor in a fuel consumption acquisition module is installed on a fuel inlet of a fuel pump; a returned fuel amount sensor is installed on a fuel returning path from the fuel pump to a fuel tank; a fuel amount adjusting valve is installed on a fuel path between the inflow fuel amount sensor and the fuel tank; an accelerator opening degree acquisition module is in linkage with an accelerator pedal; a fuel temperature acquisition module is installed on a fuel path between the returned fuel amount sensor and the fuel tank; a gear position acquisition module is installed on a gear shift lever; and a controller is connected with the fuel consumption acquisition module, the accelerator opening degree acquisition module, the fuel temperature acquisition module and the gear position acquisition module. The invention further discloses a fuel controllability adjusting method used for the heavy vehicles. The fuel controllability adjusting device and method used for the heavy vehicles have the beneficial effects that data can be acquired online in real time and can be analyzed, whether heavy armored devices stably and normally run or not can be determined, and the energy consumption efficiency of fuel can be within a certain range.

Description

technical field [0001] The invention relates to the field of heavy-duty vehicle performance detection, in particular to a fuel controllability adjustment device and method for heavy-duty vehicles. Background technique [0002] The fuel consumption rate is an important index to evaluate the economy of an internal combustion engine and one of the important measurement parameters of an internal combustion engine. Therefore, the measurement of the fuel consumption rate is an important part of the performance of an internal combustion engine. For armored equipment engines, the importance of real-time measurement of the engine's fuel consumption efficiency lies in: First, by measuring the actual fuel consumption of heavy armored equipment during use to determine fuel efficiency, thereby improving the accuracy of fuel supply and improving Guarantee efficiency, which has a major impact on precise guarantee; second, through the measurement of fuel consumption and data analysis of fue...

Problems solved by technology

[0004] The present invention designs and develops a fuel controllable adjustment device and method for heavy vehicles. One of the purposes of the present invention is to solve the installation of an accurate acquisition device for fuel consumption efficiency during the operation of heavy armored equipment in the prior art. Inconvenient, inaccurate data collection, poor real-time monitoring effect, unable to adjust the fuel volume through controllability to keep the fuel consumption efficiency in a stable state, etc.

[0005] The second purpose of the present invention is to solve the inaccurate calculation of the controllability adjustment of fuel consumption efficiency in the prior art, which only considers the amount of fuel and fails to take into account the relevant parameters during the operation of heavy-duty bicycles question
