The effect similar to that of water gas can be generated, combustion is more sufficient, emission of black smoke is reduced, the working environment is improved, heat of the cylinder wall is used for heating, and the energy-saving and environment-friendly effects are achieved.

Description

TECHNICAL FIELD

[0001] The utility model relates to the cylinder technical field of diesel engine, specifically relates to an energy -conserving and environment -friendly diesel engine cylinder structure. BACKGROUND

[0002] The thermal efficiency and economy of diesel engine are better than gasoline engine, and the torque of diesel engine is big under the condition of same power, the rotating speed at maximum power is low, and carbon smoke and particle (PM) emission are serious, so diesel engine is seldom favored by sedan all the time. The equipment using diesel engine as the driving system will emit black smoke in the operation process, not only causes the working environment of operating personnel to be smoky, but also seriously harms the environment, so the problem of black smoke emission of diesel engine is urgent to solve, and the main reason of black smoke is that diesel is not combusted fully, and the diesel combusted not fully is cracked into carbon particle and discharged into the atmosphere, which is the black smoke seen. SUMMARY

[0003] The utility model solves the technical problem that: provide an energy -conserving and environment -friendly diesel engine cylinder structure to solve the problem of black smoke emission of diesel engine due to insufficient combustion, can reduce black smoke emission, improve the working environment and be more environmental protection.

[0004] The utility model discloses a kind of energy -conserving and environment -friendly diesel engine cylinder structures, including cylinder and install in the oil nozzle of cylinder top, the outer side of the cylinder wall of cylinder is equipped with water vapor heating cavity, cylinder top is equipped with water vapor spray head and water vapor spray head is located in oil nozzle side, water vapor spray head is connected with the air outlet of water vapor heating cavity by inlet pipe.

[0005] Further, the water inlet of the above-mentioned water vapor heating cavity is connected to the water outlet of the water storage tank through the water supplement pipe, the position height of the water storage tank is higher than the water vapor heating cavity, and the water supplement pipe is provided with a water inlet valve. When the liquid level in the water vapor cavity decreases to the set position, the water supplement valve is opened, and the water vapor cavity can be watered.

[0006] Further, the air outlet of the above-mentioned water vapor heating cavity is connected to the upper end of the water storage tank through the pressure adjusting pipe, and the pressure adjusting pipe is provided with a regulating valve. When the regulating valve is opened, the air outlet of the water vapor heating cavity and the upper end of the water storage tank are connected through the pressure adjusting pipe, the pressure balance can be achieved, and the water supply to the water vapor heating cavity can be further facilitated.

[0007] The utility model discloses a beneficial effect: compare with prior art, the utility model discloses a high temperature that the cylinder itself works produces, passes through the heat transfer of cylinder wall to water vapour heating cavity, heats the water in water vapour heating cavity into high temperature water vapour with pressure, adds to the combustion chamber, and water vapour and carbon that diesel oil cracking comes out can react to generate carbon monoxide and hydrogen under high temperature, can produce the effect similar to water gas, makes combustion more fully, reduces the emission of black smoke, improves the working environment, and utilizes the heat of cylinder wall heating, plays the role of energy saving and environmental protection, the gas outlet of water vapour heating cavity and the upper end of water storage tank are connected through pressure adjusting pipe, play the role of balancing the pressure in water storage tank, prevent the situation that water does not go in because of the excessive pressure in water vapour heating cavity.
