Meanwhile, in extremely cold environment, the temperature of the body of the diesel engine and the temperature of engine oil are low, the viscosity of the engine oil is high, and the insufficient supply of the engine oil among all the kinematic pairs of the diesel engine causes the increase of the friction resistance moment.

Meanwhile, intake preheating is adopted to increase the intake temperature so as to ensure that the diesel oil spray in the cylinder successfully catches fire. Common inlet preheating means include electrically heated grilles and flame glow plugs.

the general external structural top view, front view and right side view of this embodiment are shown in fig. 5.
The internal structure and the working principle of the embodiment are as follows:
Fresh air enters from the inlet of the supercharger, the flow speed of the fresh air is increased after the fresh air passes through the impeller 14 which rotates at a high speed in the supercharger, and the fresh air is decelerated and pressurized by the volute 1 of the supercharger to form high-pressure air. And then into regenerator 2 and heated by exhaust gas from the turbine into combustion chamber 4.
As shown in FIG. 4, after entering the combustion chamber 4, the high-temperature and high-pressure air enters the inner swirler 24, the inner swirler 25, the outer swirler 25, and the outer flow passage 29 between the combustion chamber housing 26 and the combustor basket 7. The air in the outer flow passage 29 re-enters the inner flow passage 28 through the dilution holes in the combustion inner casing. The inner layer swirler 24 and the outer layer swirler 25 have opposite rotation directions, fuel sprayed by the fuel injector 23 is atomized and evaporated under the action of opposite rotational flow air, then the fuel and the air generate combustion reaction in the inner flow passage 28 to generate high-temperature and high-pressure combustion waste gas, the high-temperature and high-pressure combustion waste gas enters the turbine shell 5 to push the turbine 21 to rotate at a high speed and then is changed into low-pressure and high-temperature waste gas, the low-pressure and high-temperature waste gas enters the heat regenerator 2 through the waste gas pipe 9 and then is discharged, the temperature of the discharged waste gas is still high, and the high-temperature and high-pressure combustion waste gas can be used as a high-temperature heat source to heat cooling liquid and engine oil of the diesel engine.
The turbine 21, the generator rotor 6 and the supercharger impeller 14 are fixedly connected with the rotating shaft 15 and can coaxially rotate, and the turbine 21 synchronously drives the generator rotor 6 and the supercharger impeller 14 to rotate at a high speed. The impeller of the supercharger rotates at a high speed, then the fresh air is pressurized and sent into the heat regenerator 2, and the circulation reciprocating continuous work is carried out. As shown in fig. 3, the rotating shaft 15 is fixed to the engine stator 7 and the generator cover 8 via a high-speed bearing 20, the permanent magnet 18 is fixed to the generator rotor 6, a groove is formed in the generator stator 7, and the coil 17 is disposed in the groove. The magnetic field formed by the permanent magnet 18 rotates at a high speed with the rotation of the generator rotor, causing the coil 17 to cut the magnetic induction lines and output current, and outputting electric energy to the outside through the connection terminal 13.
The present disclosure requires the addition of an electric fuel pump and an electric lube pump, as well as a generator controller. The electric fuel pump and the electric lubricating oil pump are respectively used for conveying fuel to the fuel inlet pipe 3 and conveying lubricating oil to the lubricating oil inlet pipe 10, and the wiring terminal 13 is connected with the vehicle-mounted power supply through the motor controller. Wherein, the generator controller can control the motor to work in two modes: a start mode and a generate mode. In the starting mode, the generator can be used as a starting motor to drive the rotor to an ignition rotating speed; and in the power generation mode, the rotating speed kinetic energy is converted into electric energy to be output. High-pressure lubricating oil enters the spiral oil passage 22 on the periphery of the stator of the generator through the oil inlet pipe 10 to cool the motor, and then is sprayed on the bearing 20 through the lubricating oil delivery pipe 16 and the corresponding oil passage to form good lubrication. And then, the lubricating oil enters the oil pan 19 and then enters the lubricating oil pump for recycling.
The working process of the method is as follows:
and turning on the vehicle-mounted power supply, and starting the electric fuel pump and the electric lubricating oil pump. The motor controller controls the motor to work in a starting mode, and direct current of the vehicle-mounted storage battery is inverted into alternating current through the controller and the access terminal and then drives a motor rotor to drive the supercharger impeller 14 to rotate at a high speed. The fresh air is compressed by the supercharger impeller 14, the temperature and the pressure of the compressed fresh air are increased, and the compressed fresh air enters the regenerator 2 and then enters the combustion chamber 4. Then, the fuel injector 23 starts to inject fuel, and after atomization and evaporation are performed by the reverse swirling air, the fuel reacts with air in the inner flow passage 28 to generate high-temperature and high-pressure combustion exhaust gas, and the high-temperature and high-pressure combustion exhaust gas enters the turbine housing 5 after changing the direction through the turbine connecting pipe 30 of the combustor, and pushes the turbine 21 to rotate at a high speed and then becomes low-pressure and high-temperature exhaust gas. The turbine 21 drives the permanent magnet 18 to rotate at a high speed and generate an electromagnetic field rotating at a high speed, and the stator coil 17 in the high-speed rotating magnetic field cuts the magnetic induction line and generates an alternating electromotive force on the connecting terminal 13. And the motor controller calculates and obtains the rotating speed of the generator rotor according to the alternating electromotive force change frequency on the wiring terminal 13. When the rotating speed of the rotor of the generator reaches the target rotating speed and stably runs, the motor controller changes the working mode of the motor into a power generation mode and continuously outputs electric energy outwards. The low-pressure high-temperature waste gas from the regenerator 2 can be used for heating the cooling liquid and the engine oil of the diesel engine and continuously outputting heat energy outwards. In practice, the flow ratio of the inner flow passage 28 and the outer flow passage 29 in the combustion chamber 4 may be adjusted to control the electrical energy output and thermal energy output ratio of the present disclosure.
Therefore, the single-pipe combustion turbocharging combined heat and power generation system provided by the disclosure makes up the defects of the existing heater, can effectively accelerate the preheating process of the cooling liquid and the engine oil of the diesel engine, charges the vehicle-mounted storage battery, and can remarkably improve the cold starting performance of the diesel engine in extremely cold severe environment. Meanwhile, the main engine of the vehicle is not started, and the single-pipe combustion turbocharging combined heat and power generation system can also continuously supply power to the vehicle-mounted electronic equipment, so that the fuel is saved and the noise is reduced.
The foregoing is illustrative of the present invention and various modifications and changes in form or detail will readily occur to those skilled in the art based upon the teachings herein and the application of the principles and principles disclosed herein, which are to be regarded as illustrative rather than restrictive on the broad principles of the present invention.
