Device and method for recycling automobile braking energy

Abstract

The invention provides a device and method for recycling automobile braking energy, belonging to the technical field of automobile energy conservation and emission reduction. Aiming at the problem that a large number of braking energy is wasted during the frequent or long time braking procedure of an automobile, an automobile rotation shaft power generation device is added to prevent the large number of braking energy from wasting, so that mechanical energy is transformed into electric energy; and a part of the electric energy transmitted by a generator is used for fuel catalytic reforming, and the generated reformed gas is led into a gas inlet pipe of a diesel engine to be mixed with the diesel oil for combustion; and the other part of the electric energy is used for heating up the inletgas of the diesel engine. In the invention, by the combined actions of an automobile rotation shaft power generation device, a fuel catalytic reforming device, a diesel engine inlet gas heating device and a control system, the braking energy of automobiles is recycled, the combustion and emission performances of diesel engines in idling are greatly improved, and the energy conservation and emission reduction of diesel engines are realized.

Description

technical field [0001] This patent relates to a device and method for recovering and utilizing braking energy of automobiles. Specifically, a large amount of braking energy will be wasted when heavy-duty vehicles brake frequently and for a long time. A control system is used to recover and utilize the braking energy, which belongs to the technical field of vehicle energy saving and emission reduction. Background technique [0002] Aiming at the problem of recovering the braking energy of heavy-duty trucks during the long-term downhill braking process, one method is to install a retarder on the heavy-duty truck, and the retarder converts its braking energy into a large amount of heat energy during the braking process , due to the limitation of the material performance of the retarder itself, the limit temperature that it can withstand under the premise of ensuring its normal operation is low, so the heat energy produced is low-grade heat energy, and the waste heat utilization...

Problems solved by technology

[0005] The solution of the present invention is aimed at the problem that a large amount of braking energy will be wasted during frequent or long-term braking of heavy-duty vehicles. The braking energy can be recycled into electric energy through the automobile rotating shaft power generation device, and then used for heating The resistance wire in the reformer, the resistance wire generates heat to raise the temperature of the reformer, when the temperature in the reformer reaches the required temperature, the reformed fuel is pumped into the reformer for catalytic reforming, and the produced The reformed gas enters the reformed gas storage tank. When the required pressure is reached in the reformed gas storage tank, the reformed gas is evenly introduced into the intake pipe of the diesel engine and enters the electric heater together with the air passing through the air filter for heating. The heated mixed gas Into the mixed combustion of diesel engine and diesel to achieve the purpose of improving the combustion of diesel engine and reducing its emission
