Problems solved by technology

Since the working method of the piston engine is intermittent ignition, the existing four-stroke piston engine, after years of evolution, has continuously improved the compression ratio and continuously optimized the combustion method, but until now, it is still unable to overcome insufficient combustion and exhaust gas. Insufficient oxidation and other disadvantages, this has caused the existing range-extended electric vehicles to still need to use a complete set of exhaust gas treatment systems used in existing piston engines

Embodiment 1

[0049] The present invention provides a kind of turbine engine, its structure such as figure 1 As shown, it includes: combustion chamber 1-1, pressure regulating nozzle 1-2, intake turbine 1-3, exhaust turbine 1-4, tail nozzle 1-5 and transmission shaft 1-6.

[0050]The intake turbine 1-3 is a suspended rotating turbine rotor. This is because the gap between the edge of the rotor and the inner wall of the engine cavity is very small. When the strong airflow passes through, it will generate a huge force, thereby pushing the suspended rotor to rotate. The higher the rotor speed, the greater the effect. The greater the force. The intake turbine 1-3 is provided with guide vanes, which are installed at the inlet of the air inlet, and the incoming gas is introduced into the intake pipe of the combustion chamber 1-1 through the guide vanes; the combustion chamber 1-1 has a certain length, for Let the air flow quickly and burn more fully. The air inlet of the combustion chamber 1-1 ...

Embodiment 2

[0054] The invention also provides a range-extended electric vehicle, the structure of which is as follows: figure 2 and image 3 As shown, it specifically includes the following components: turboshaft engine 1; turboshaft engine controller 2; generator 3; battery pack 4; battery controller 5; drive motor 6, battery radiator 7; battery heat management system 8 (Fig. Not shown in); Gas storage tank 9; Central controller 10, wheels 11 and vehicle frame 12.

[0055] Vehicle frame 12 comprises the shell of whole automobile, chassis and the handling equipment that is arranged on chassis; wherein turboshaft engine 1 is arranged on chassis; Turboshaft engine controller 2; Generator 3; Battery pack 4; Battery controller 5; Drive motor 6. Battery radiator 7; battery heat management system 8; gas storage tank 9; and central controller 10.

[0056] The signal terminal of the turboshaft engine 1 is connected to the turboshaft engine controller 2, and the turboshaft engine controller 2 ...

Embodiment 3

[0075] The present invention also provides another extended-range electric vehicle, which, on the basis of the second embodiment above, also includes the following Figure 5 The following components are shown: heat energy recovery device 13; heat energy delivery pipe 14; compressed air heater 15.

[0076] The above-mentioned heat energy recovery device 13 is arranged at the tail of the combustion chamber of the turboshaft engine, and is used for absorbing the heat generated by the combustion of the turboshaft engine 1 . The heat energy recovery device 13 is a finned heat exchanger, so that the effect of absorbing heat energy is better.

[0077] The inlet end of the heat energy delivery pipe 14 is connected to the heat energy recovery device 13 , and the outlet end is connected to the compressed air heater 15 . Through the heat energy delivery pipe 14 , the heat recovered by the heat energy recovery device 13 is transferred to the compressed air heater 15 .

Abstract

The invention provides an extended range electric vehicle. A signal end of a turboshaft engine (1) is connected with a controller (2) of the turboshaft engine, and a transmission shaft is connected with a rotating shaft of an electric generator (3). The electric generator (3) outputs electric energy and transmits the electric energy to a battery pack (4) and a driving motor (6). The battery pack (4) is connected with the driving motor (6) and is connected to a battery controller (5) at the signal end. A transmission shaft of the driving motor (6) is connected with vehicle wheels (11). A cold air duct of a battery radiator (7) leads to the battery pack (4). An air transporting pipeline of an air storage tank (9) is connected with a fuel gas input pipeline of the turboshaft engine (1). According to the extended range electric vehicle, the advantage of the turboshaft engine is developed, and an efficient, stable and environment-friendly system is formed through the turboshaft engine, the driving motor, the battery pack and a central controller. The extended range electric vehicle has the advantages that the power to weight ratio is high, the power consumption is low, the emission is low, the noise and vibration are low, an off-gas treatment system does not need to use, the maintenance is easy, and the service lift is long.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a range-extended electric vehicle. Background technique [0002] With the deterioration of air quality and more and more people's awareness of environmental protection, extended-range electric vehicles, as new energy vehicles, are becoming more and more popular under the impetus of many objective factors. [0003] An extended-range electric vehicle refers to a purely electric-driven electric vehicle equipped with ground charging and on-board power supply functions, that is to say, an extended-range electric vehicle is driven by electricity throughout. The power system of an extended-range electric vehicle is composed of a power battery system, a power drive system, a vehicle control system and an auxiliary power unit (APU), and the vehicle controller completes the operation control strategy. [0004] In the existing range-extended electric vehicle design, the generator set used in the...
