Embodiment 1

[0074] Such as figure 1 The schematic diagram of the engine automatic control air intake system is shown, the engine automatic control air intake system 4 is connected with the air intake port 2 of the engine body 1 to the automatic control air intake system air outlet 3, forming an air intake automatic control engine. Engines include: piston engines, rotary engines, jet engines, turbojet engines, turbofan engines, gas turbines. The automatic control air intake system is composed of: the sensor set on the engine air inlet 2 is connected to the input end of the controller, and the actuator is connected to the output end of the controller. Perform comparison, analysis, diagnosis, and calculation to draw correct conclusions, and then send control instructions to the output terminal to control the actuator to make correct adjustments to ensure that the system control parameters are within a reasonable range. The control parameters include: intake pressure, temperature, flow, Air ...

Embodiment 2

[0079] Such as figure 2 The shown schematic diagram of the air intake automatic control engine in which the air supercharger 6 is connected in parallel with the natural intake air is based on the embodiment 1, and the natural intake system is added.

[0080] The outlet of the air supercharger 6 is connected to the outlet of the natural intake system through the connection cavity, the air supercharger 6 is connected to the output end of the central controller, and the sensor arranged on the engine air inlet 2 is connected to the input end of the controller. The sensor detects the signal of the engine air inlet and outputs it to the controller, and the controller outputs instructions to control the speed of the air supercharger 6 and the output flow of air.

[0081] The parallel natural air intake system can effectively make up for the defect of insufficient air intake of the air supercharger when the engine rotates at a high speed. The air outlet 3 of the natural air intake s...

Embodiment 3

[0084] Such as image 3 Schematic diagram of the structure of the engine with automatic intake control of the dual air-driven turbocharger shown. The exhaust pipe of the engine passes through the heat exchanger to drive the turbocharger, and at the same time, the waste heat of the engine is transferred to the heat exchanger to be converted into steam. The steam and the output end of the exhaust gas of the engine are connected to the input end of the turbocharger, and the steam and the exhaust gas jointly drive the turbocharger.

[0085] It also includes: the heat exchanger is arranged on the turbocharger. In this way, the heat of the turbocharger can be absorbed to lower its temperature, and the hidden danger of high temperature and flammability can be eliminated. Steam and exhaust jointly drive the turbocharger, which can also make up for its low speed and low efficiency.

[0086] The sensor arranged on the engine air inlet 2 is connected to the input terminal of the contr...

Abstract

The invention discloses an air inlet automatic control engine. The air inlet automatic control engine comprises an engine body and an automatic control air inlet system, an air inlet of the engine body is in communication with an air outlet of the automatic control air inlet system, an air inlet of the automatic control system is provided with a connecting cavity and a sensor, the connecting cavity is connected with a natural gas inlet pipe and / or an air pressurizer, and the sensor is connected with an air pressurizer through a controller in the automatic control air inlet system. The automatic control system has the advantages that automatic control of an engine air inlet system is achieved, and the negative pressure air inlet phenomenon is effectively eliminated; the air inlet pressure and the temperature are ensured to be stable; the air inlet flow is synchronously changed along with the oil inlet flow, so that the engine achieves high-efficiency, energy-saving and environment-friendly operation levels; the tail gas emission is lower than the emission standard, so that the problem of black smoke of a diesel engine is effectively solved; high-pressure steam is generated by a heatexchanger, a double-gas-drive steam turbine and a turbocharger increase the power, so that the risk of high-temperature inflammability of the turbocharger is eliminated and the rotating speed of theturbocharger is controlled.

Description

technical field [0001] The invention belongs to the technical field of engines, in particular to an engine with automatic air intake control. Background technique [0002] Existing engines are mainly naturally aspirated and turbocharged aspirated. Whether it is natural intake or turbocharged intake, there is no automatic control. People overlook the importance of air intake to the engine. Exhaust turbochargers, which are widely used, only operate randomly, and cannot be controlled artificially or automatically to control their speed, air output flow and pressure, and cannot guarantee that the engine intake pressure and temperature are stable and operate within the optimal range. There is no guarantee that the intake flow will change synchronously with the oil flow and match reasonably. Especially when the engine is running at low speed, the intake air flow cannot keep up with the increase of the oil intake flow. The ratio of oil and gas in the cylinder cannot be matched,...
