Embodiment Construction

[0044] A waste heat utilization system of a biomass internal combustion engine, such as figure 1 As shown, it includes a condenser 17, a main control ECU 19, an internal combustion engine waste heat recovery unit, a heat exchanger 6, an oil pump 7, a heat conversion unit, an intake solenoid valve 10, an exhaust solenoid valve 16, an oil storage tank 8 and a piston 12.

[0045] The system described in this embodiment is used to recycle the waste heat of the internal combustion engine of the vehicle, wherein the condenser 17 is an existing component in the vehicle, and its temperature is relatively low to realize condensation.

[0046] The main control ECU19 is also an existing component in the vehicle, which includes a single-chip microcomputer (model AT89S51) that can analyze the received signal to obtain a control signal. The analysis method in this embodiment is a mature prior art and does not involve Program improvements.

[0047] There is a thermal chamber 11 in the ther...

Abstract

The invention discloses a system and method for utilizing waste heat of a biomass energy internal combustion engine. The system comprises a condenser, an internal combustion engine waste heat recovery part, a heat exchanger, an oil pump, a heat cavity, an oil storage tank and a piston; the internal combustion engine waste heat recovery part is connected with a heat conduction medium inlet of the heat exchanger; an oil outlet of the oil pump is connected with a heated medium inlet of the heat exchanger; and a heated medium outlet of the heat exchanger is connected with an inlet of the heat cavity. The method comprises the following steps: (1) under the condition that the piston is positioned at a top dead center, organic liquid exchanges heat with waste heat to change from a liquid state to a gas state; (2) the gas-state organic liquid enters the heat cavity and pushes the piston to move towards a bottom dead center; (3) when the piston reaches the bottom dead center, an intake valve and an exhaust valve are both closed; (4) as the pressure in the heat cavity is reduced, atmospheric pressure pushes the piston to move towards the top dead center to enable the piston to reach the top dead center; and (5) the steps (1), (2), (3) and (4) are repeated in sequence. Full utilization of the waste heat of the internal combustion engine is realized, the energy utilization rate of the internal combustion engine is increased, and the energy consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of waste heat utilization of internal combustion engines, and in particular relates to a waste heat utilization system and method of a biomass internal combustion engine. Background technique [0002] With the rapid development of China's industry, the number of automobiles has increased rapidly, accompanied by the rapid consumption of oil energy and the aggravation of environmental pollution. All countries in the world are actively seeking solutions. [0003] Improving the utilization efficiency of traditional fossil energy and seeking renewable energy are both feasible solutions. However, it is difficult for renewable energy to completely replace fossil energy and undertake the energy consumption of human society in a short period of time. Therefore, improving the utilization efficiency of petroleum energy can greatly delay the energy use cycle and reduce environmental pollution. [0004] The thermal effi...
