Description

Energy-saving power units for automobiles

technical field

The utility model relates to an energy-saving power device for automobiles, which belongs to the field of energy-saving equipment.

Background technique

At present, the engines used in automobiles are all internal combustion engines. The internal combustion engine is a thermodynamic machine that converts chemical energy into heat energy through the combustion of fuel, and then converts heat energy into mechanical energy. Take the gasoline engine as an example, the engine mixes air and gasoline in a certain proportion to form a good mixture, which is sucked into the cylinder during the intake stroke, and the mixture is compressed and ignited to generate a large amount of heat energy, making the pressure of the gas in the cylinder and a rapid increase in temperature. The maximum combustion pressure reaches 3000-6000kPa, and the temperature reaches 2200-2800K. The high-temperature and high-pressure gas acts on the top of the piston, pushing the piston to make a reciprocating linear motion, and outputs mechanical energy through the connecting rod, crankshaft and flywheel mechanism. When the piston moves, the cylinder volume increases, and the gas The pressure and temperature drop gradually, usually the pressure drops to 300-500kPa, and the temperature drops to 1200-1500K. Usually, this part of the heat will be directly discharged through the exhaust pipe, which consumes a lot of heat energy, which is not conducive to energy saving and emission reduction.

Utility model content

Based on the deficiencies in the prior art above, the technical problem to be solved by the utility model is: to provide an energy-saving power device for automobiles that can make full use of the heat energy generated when the engine is working and has a good energy-saving effect.

The technical scheme adopted by the utility model to solve the technical problems is: the energy-saving power device for automobiles includes an engine, an exhaust gas pipe is installed on the engine, and a water pipeline is arranged on the periphery of the engine. The air inlet, water inlet, and the gas pipeline connected to the exhaust port are connected to the intake end of the steam turbine. The power output end of the steam turbine drives the wheels of the car. The exhaust end of the steam turbine is connected to the radiator through the exhaust pipe. The outlet of the radiator The water port is connected with the water inlet of the water pipeline through a pipeline, a high-pressure pump is installed on the pipeline, and a water supply device is connected on the pipeline between the radiator and the high-pressure pump.

Working principle and process:

A large amount of heat is generated when the mixed gas inside the engine is compressed, ignited and burned. The temperature of the high-temperature and high-pressure gas in the engine is as high as 2200-2800K. This part of the heat will turn the water in the water pipeline around the engine into steam, and the steam will pass through the gas pipeline. Entering the steam turbine, the steam turbine converts the energy of this steam into mechanical energy and drives the wheels of the car as an auxiliary power unit, thus making full use of the heat energy. The steam discharged from the exhaust end of the steam turbine is connected to the radiator through the exhaust pipe for cooling and cooling. The cooling water is pumped into the water pipeline through the high-pressure pump for recycling, and water is added to the water pipeline in a timely manner through the water supply device to ensure circulation. Plenty of water.

The number of exhaust pipes is 1-30. The more exhaust pipes are installed, the larger the contact area between the exhaust gas from the engine and the water pipe, the easier it is to absorb the heat in the exhaust gas and make full use of this part of the heat.

The beneficial effects that the utility model has are:

The energy-saving power unit for the entire vehicle uses a large amount of heat generated when the engine is working to turn the water in the water pipe around the engine into steam and send it to the steam turbine so that the thermal energy of the steam is converted into mechanical energy and used as an auxiliary power unit to drive the wheels of the vehicle. Therefore, the heat energy generated when the engine is working is fully utilized, and the utilization rate of heat energy is improved, and auxiliary power can be provided for the automobile at the same time, and the energy-saving effect is good.
