Embodiment Construction

[0008] like figure 1 As shown, the exhaust gas secondary combustion intake system of this diesel engine includes a cylinder assembly 1, an intake pipe 2, and an exhaust pipe 3. The intake pipe 2 is connected to one end of the cylinder assembly 1, and the exhaust pipe 2 is connected to the cylinder assembly 1. At the other end of the pipe, a round pipe 4 is set between the intake pipe 2 and the exhaust pipe 3, and a threaded guide groove 5 is set in the round pipe 4. One end of the round pipe 4 is connected to the intake pipe 2, and the other end of the round pipe 4 is connected to the On the exhaust pipe 3 , the two ends of the round pipe 4 communicate with the intake pipe 2 and the exhaust pipe 3 .

Abstract

The invention relates to a secondary combustion intake system of diesel engine exhaust, belonging to an intake device, in particular to a secondary intake device used on a diesel engine for collecting exhaust. The secondary intake device on the diesel engine for collecting exhaust comprises an air cylinder assembly, an intake pipe and an exhaust pipe, wherein the intake pipe is connected to one end of the air cylinder assembly, the exhaust pipe is connected to the other end of the air cylinder assembly, a round pipe is arranged between the intake pipe and the exhaust pipe, a threaded guide groove is arranged in the round pipe, one end of the round pipe is connected to the intake pipe, the other end of the round pipe is connected to the exhaust pipe, and both ends of the round pipe are communicated with the intake pipe and the exhaust pipe. By using the secondary combustion intake system, oil consumption of a diesel can be reduced by 14 percent and smoke emission is not more than 261 g / km.

Description

technical field [0001] The invention relates to an air intake device, in particular to a device for collecting exhaust gas on a diesel engine and allowing secondary air intake. Background technique [0002] Most common agricultural diesel engines use compressed air to inject fuel into high-temperature cylinders at high pressure, so that the fuel can spontaneously ignite and burn. Since the fuel is directly injected into the cylinder, high-density and low-density areas are prone to appear in the cylinder. In addition, due to the low temperature of the exhaust gas, it is difficult for the catalytic converter to play an effective role, resulting in a high content of harmful nitrogen oxides in the exhaust emission, which will cause great harm to the living environment of human beings and their own health. Contents of the invention [0003] In order to solve the problems of incomplete combustion and high nitrogen oxides in the tail gas of the existing common agricultural diesel...
