Intelligent and efficient purification method and device for turbocharged diesel engine

Abstract

The invention relates to an intelligent control system of an efficient purifying device of a turbo-charged internal combustion engine, in particular to a turbo-charged diesel engine system. An intelligent efficient purifying method for a turbo-charged diesel engine is characterized in that superheated steam is introduced into air cylinders of the engine of a diesel engine by a superheated steam pipe directly, so that the steam and air can independently and separately enter the air cylinders. An intelligent efficient purifying device for realizing the method comprises a water tank, wherein a cold water pipe for water outgoing of the water tank is provided with a water inlet pipe valve and is connected with a water inlet of a heat exchanger water tank; the heat exchanger water tank is arranged on the outer wall of an exhaust pipe of the engine and is used for heating a water source in a heat exchanging manner; a water outlet pipe of the heat exchanger water tank is connected into the water tank through a steam outlet of a steam-water separator; a water outlet of the steam-water separator is connected into a flow controller through a water pump; the flow controller is connected into a superheat evaporator. The defect of other patented technologies of steam power that the air cylinders are corroded by acid produced from reduced water resulting from mixing and cooling of the steam and the air and sulfur is overcome.

Description

technical field [0001] The invention relates to an intelligent control system of a high-efficiency purification device for a turbocharged internal combustion engine. Especially the improvement of turbocharged diesel engine system. Background technique [0002] Judging from the current engine thermal efficiency and exhaust emissions, due to insufficient combustion of engine fuel, the power output of the power only accounts for 40%-50% of the total heat of fuel combustion (diesel engine) or 30%-35% (gasoline engine), and other heat is cooled. System and exhaust emissions into the atmosphere causing air pollution. Therefore, recovery of engine exhaust heat is an effective way to improve engine thermal efficiency. From the perspective of domestic and foreign exhaust energy utilization technologies, there are refrigeration, heating, thermoelectric power generation, fuel catalytic reforming, followed by a power turbine, and the installation of a power cycle device. Due to the l...

Problems solved by technology

The patent has the disadvantage of installing a heating tube in the abdominal cavity of the exhaust pipe to heat water: it will increase the exhaust resistance of the cylinder, reduce the air intake of the cylinder, and reduce the engine power performance

Since the air-oil-air mixing ratio is as high as 1:25 or more, when the superheated steam and air are mixed, cooling will occur immediately due to the temperature drop to produce steam condensate, and the steam condensate reacts with (S) sulfur produced by oil combustion to form sulfuric acid to corrode the cylinder block, above The technology has the disadvantages of low thermal efficiency of exhaust gas recovery and corrosion of the cylinder
