Embodiment 1

[0012] In the diesel engine integrated power supply system described in the present invention, the exhaust device of the diesel engine is respectively connected with the exhaust gas turbine generator, the thermoelectric power generation module, the generator and the starter generator; then the exhaust gas turbine generator, the thermoelectric power generation module, the generator and the starter generator Then they are respectively connected with the electric storage equipment; the electric storage equipment is connected with the automatic management module and various electric equipments. Wherein said starter generator is a dual-mode reversible motor. When the vehicle brakes and goes downhill, it is used as a generator to recover braking energy and convert downhill energy into electrical energy. If the power generation can meet the power demand of the model, some integrated modules can be canceled to reduce the number of components and reduce the energy consumption of the di...

Abstract

The invention relates to a diesel engine exhaust energy gradient utilization and integration system, namely a diesel engine integrated power supply system. An exhaust device of a diesel engine is connected with an exhaust-driven gas turbine generator, a thermoelectricity generating module, a generator and a starting generator respectively, the exhaust-driven gas turbine generator, the thermoelectricity generating module, the generator and the starting generator are connected with an electric power storage device respectively, and the electric power storage device is connected with an automatic management module and various electricity using devices. According to the diesel engine integrated power supply system, due to the fact the electric energy obtained through exhaust energy conversion is increased, self-generating electricity energy in hybrid power is increased, the electric energy driving proportion is improved, and the energy conservation and emission reduction effect of oil-electricity hybrid power is enhanced.

Description

technical field [0001] The invention relates to a cascaded utilization and integration system of diesel engine exhaust energy. Background technique [0002] For a long time, when the diesel engine is running, the exhaust gas is directly discharged into the atmosphere and becomes useless exhaust gas with pollutants. From the exhaust energy analysis, it can be seen that there is a large amount of heat energy and kinetic energy in the exhaust gas (which can be called the waste heat and energy of the diesel engine), which is the "potential" that can be converted into useful output work, and the "exhaust gas" is not waste in essence. At present, there have been many achievements in the application of exhaust kinetic energy and thermal energy. Such as: exhaust gas turbocharging, exhaust gas recirculation, exhaust gas turbine power machine, thermoelectric power generation module, exhaust gas heating operation device, etc. However, these exhaust energy utilization results are mo...
