Heat recovery four-stroke four-cylinder-driven turbine power generation system

Abstract

The invention relates to power generation systems of extended-range cars. A heat recovery four-stroke four-cylinder-driven turbine power generation system comprises four four-stroke engine cylinders connected together through a cylinder frame, a power generator and a turbine system. Cylinder blocks of the cylinders are arranged in the high-temperature end of a first thermoelectric power generation pipe in a penetrating mode. The cylinder frame is provided with a sliding chute and a pulley connected in the sliding chute. The four engine cylinders drive the pulley to do straight reciprocating motion. The turbine system comprises a water turbine driving the power generator to generate power, and a circulating liquid flow mechanism driving the water turbine to rotate. The circulating liquid flow mechanism comprises a hydraulic piston. The hydraulic piston is connected with the pulley. The heat recovery four-stroke four-cylinder-driven turbine power generation system has the advantage that power generation can be conducted through heat of the cylinders without the need of a crankshaft and a linear motor, and the defects that cylinders drive power generators to generate power through crankshafts or directly drive linear motors to generate power, and energy is consumed for cooling the power generator cylinders are overcome.

Description

technical field [0001] The invention in this application relates to a power generation system for a range-extended vehicle, in particular to a heat recovery four-stroke four-cylinder drive turbine power generation system. Background technique [0002] The power generation system of a range-extended vehicle, one power generation method is that the piston of the internal combustion engine pushes the crank, which converts the linear motion of the cylinder into the rotational motion of the crank, and the crank rotates to drive the generator to generate electricity. The disadvantage of this power generation system is: when the fuel is ignited, the piston turns to the top attachment, and the crankshaft bears the highest pressure of the cylinder at the top attachment, the friction loss is very large, and the total efficiency drops obviously. [0003] The heating of the engine cylinder requires energy to be cooled, resulting in high energy consumption. [0004] The other is to dire...

Problems solved by technology

The disadvantage of this power generation system is: when the fuel is ignited, the piston turns to the top attachment, and the crankshaft bears the highest pressure of the cylinder at the top attachment, the friction loss is very large, and the overall efficiency drops obviously

[0003] The heating of the engine cylinder requires energy to be cooled, resulting in high energy consumption

[0004] The other is to directly connect the cylinder with the permanent magnet linear generator, save the crankshaft, and use the linear reciprocating motion of the cylinder to drive the linear reciprocating motion of the permanent magnet linear generator. This can also generate electricity, but there are several major disadvantages: 1. It is easy to cause partial or complete demagnetization of the permanent magnet generator, resulting in a significant drop in power generation and efficiency, because the permanent magnet linear generator is too close to the cylinder, the temperature is high, and it is easy to demagnetize

3 Due to various reasons, the performance of the linear permanent magnet generator is difficult to guarantee, and the price is also high, so it is difficult to mass produce
