Description

Inter-cylinder cooling structure of engine cylinder body

Technical Field

The utility model belongs to engine cylinder body system field, concretely relates to can effectively reduce cooling structure between jar of temperature between cylinder block jar.

Background

The existing mainstream engines all adopt a reciprocating working principle, which is approximately as follows: the mixed gas of fuel oil and air is injected into the cylinder and ignited, the mixed gas expands in volume when burning, the generated energy pushes the piston to move, and the up-and-down movement of the piston is converted into rotary motion through the crankshaft, so that power is output to the outside. This approach requires a continuous, high frequency combustion chemistry within the engine cylinder, generating a large amount of heat. Except that one part is used for doing work, one part of the rest heat is cooled and taken away by an engine cooling system, and the other part is conducted and dissipated through the cylinder body.

If the cooling between the cylinder blocks is poor, the nose bridge area between the cylinder blocks can be continuously located in a high-temperature state, so that the problems of cylinder cushion adhesion between the cylinder blocks and the cylinder cover, engine oil carbon deposition on the top of a cylinder hole of the cylinder block, cylinder hole strain, detonation and the like are caused, and the normal operation of an engine is influenced.

Disclosure of Invention

The utility model aims at providing a simple structure, easily processing, stable in structure can well improve cooling structure between the jar of the engine cylinder body of the too high problem of temperature between the engine cylinder body jar.

The utility model discloses an inter-cylinder cooling structure of engine cylinder body includes adjacent cylinder body, and the key lies in, is equipped with between the adjacent cylinder body to extend and run through the water tank of crossing in cylinder body nose bridge district by the side direction exhaust side that admits air, the both ends of crossing the water tank communicate with each other with the water jacket of cylinder body both sides respectively. In the working process of the engine, water of the water jacket of the cylinder body flows through the water tank, so that the nose bridge area of the cylinder body is cooled, and the overhigh temperature is avoided.

Furthermore, a V-shaped first water passing channel extending from the air inlet side to the air exhaust side is arranged between the adjacent cylinder bodies, two ends of the first water passing channel are respectively communicated with the water jackets on two sides of the cylinder bodies, and two ends of the first water passing channel and the first air ring of the piston at the top dead center position are on the same horizontal line.

Furthermore, a V-shaped second water passing channel extending from the air inlet side to the air exhaust side is arranged between the adjacent cylinder bodies, two ends of the second water passing channel are respectively communicated with the water jackets on two sides of the cylinder bodies, and two ends of the second water passing channel are on the same horizontal line with the oil scraper ring of the piston at the top dead center position.

Specifically, the inclination angles of the first water passing channel and the second water passing channel are 45-50 degrees.

The cooling water flowing through the first water passing channel and the second water passing channel cools the hotter position (the horizontal line where the first air ring and the oil scraper ring of the piston are located when the piston is located at the upper dead center position) of the cylinder body, and the first water passing channel and the second water passing channel are both V-shaped structures, so that the length of the water passing channel is increased, the improvement of the cooling effect is facilitated, the water passing channel is convenient to process, and holes are obliquely drilled downwards at two ends until inclined holes at two ends are aligned, and the V-shaped water passing channel can be formed.

The utility model discloses a mode of crossing basin and water channel is processed at adjacent jar body spare improves the cooling effect between the jar to reach and reduce the temperature between the jar, maintain the purpose that the engine lasts, even running.
