Abstract

The utility model discloses a horizontal opposition engine cylinder body, including left cylinder body and right cylinder body, the inside first water jacket that sets up of left cylinder body, the inside second water jacket that sets up of right cylinder body, first water jacket and second water jacket intercommunication, first water jacket and left cylinder body casting shaping as an organic whole, second water jacket and right cylinder body casting shaping as an organic whole. The horizontally-opposed engine cylinder body integrates the water jacket channel on the cylinder body by embedding the water jacket in the left cylinder body and the right cylinder body, has better consistency and stable flow field, is not interfered by the outside, and is beneficial to the design of an engine cooling system and the cooling of an engine; meanwhile, the embedded water jacket channel type cylinder body reduces external pipelines or link pieces, reduces sealing surfaces, reduces parts and components, reduces water leakage risks, reduces the fault rate of the engine caused by water leakage in the using process, reduces the cost of the engine simultaneously, and is particularly obvious for large engines.

Description

Horizontally opposed engine cylinder block

Technical Field

The utility model belongs to the technical field of the engine, specifically speaking, the utility model relates to a horizontal opposition engine cylinder body.

Background

The horizontally-opposed engine cylinder body is divided into a left cylinder body and a right cylinder body, the cylinder body water jackets can become a left water jacket and a right water jacket, and the left water jacket and the right water jacket need to be communicated. The existing method is to communicate the water jackets of the left and right cylinder bodies through a hose or another communication piece, the arrangement of a pipeline increases the leakage risk, the cylinder body water jacket is very critical to the engine, the high-temperature damage of the engine is easily caused by the water leakage of the cylinder body water jacket, and the cost of parts is high due to the fact that the connecting piece needs to be considered.

SUMMERY OF THE UTILITY MODEL

The utility model discloses aim at solving one of the technical problem that exists among the prior art at least. Therefore, the utility model provides a horizontal opposition engine cylinder body, the purpose reduces the cylinder body and appears the risk that the coolant liquid leaked.

In order to realize the purpose, the utility model discloses the technical scheme who takes does: the horizontally-opposed engine cylinder body comprises a left cylinder body and a right cylinder body, wherein a first water jacket is arranged in the left cylinder body, a second water jacket is arranged in the right cylinder body, the first water jacket is communicated with the second water jacket, the first water jacket and the left cylinder body are integrally cast, and the second water jacket and the right cylinder body are integrally cast.

The first water jacket is a joint surface extending from the cylinder barrel of the left cylinder body to the left cylinder body, the second water jacket is a joint surface extending from the cylinder barrel of the right cylinder body to the right cylinder body, and the joint surface of the left cylinder body is attached to the joint surface of the right cylinder body.

The horizontally-opposed engine cylinder body integrates the water jacket channel on the cylinder body by embedding the water jacket in the left cylinder body and the right cylinder body, has better consistency and stable flow field, is not interfered by the outside, and is beneficial to the design of an engine cooling system and the cooling of an engine; meanwhile, the embedded water jacket channel type cylinder body reduces external pipelines or link pieces, reduces sealing surfaces, reduces parts and components, reduces water leakage risks, reduces the fault rate of the engine caused by water leakage in the using process, reduces the cost of the engine simultaneously, and is particularly obvious for large engines.

Drawings

The description includes the following figures, the contents shown are respectively:

FIG. 1 is a schematic view of a horizontally opposed engine block of the present invention;

labeled as: 1. a left cylinder body; 2. a right cylinder body; 3. a first water jacket; 4. a second water jacket.

Detailed Description

The following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings, for the purpose of helping those skilled in the art to understand more completely, accurately and deeply the conception and technical solution of the present invention, and to facilitate its implementation.

It should be noted that, in the following embodiments, the "first" and "second" do not represent an absolute distinction relationship in structure and/or function, nor represent a sequential execution order, but merely for convenience of description.

As shown in fig. 1, the utility model provides a horizontal opposition engine cylinder body, including left cylinder body 1 and right cylinder body 2, left cylinder body 1 is inside to be set up first water jacket 3, and right cylinder body 2 is inside to be set up second water jacket 4, and first water jacket 3 and second water jacket 4 intercommunication, first water jacket 3 and left cylinder body 1 are integrated into one piece, and second water jacket 4 and right cylinder body 2 are integrated into one piece.

Specifically, as shown in fig. 1, the left cylinder body 1 and the right cylinder body 2 are arranged oppositely, a plurality of cylinders for accommodating pistons are arranged on the left cylinder body 1, all the cylinders on the left cylinder body 1 are arranged in sequence along the length direction of the left cylinder body 1, a plurality of cylinders for accommodating pistons are also arranged on the right cylinder body 2, all the cylinders on the right cylinder body 2 are arranged in sequence along the length direction of the right cylinder body 2, and each cylinder on the left cylinder body 1 and one cylinder on the right cylinder body 2 are in a coaxial state.

As shown in fig. 1, the first water jackets 3 are joint surfaces extending from the cylinder of the left cylinder 1 to the left cylinder 1, the joint surfaces are planes perpendicular to the axis of the cylinder of the left cylinder 1, the number of the first water jackets 3 is the same as that of the cylinders of the left cylinder 1, all the first water jackets 3 are sequentially arranged along the length direction of the left cylinder 1 and are distributed at equal intervals, one end of each first water jacket 3 is located at one cylinder of the left cylinder 1, and the other end of each first water jacket 3 is located on the joint surface of the left cylinder 1. The second water jackets 4 are joint surfaces extending from the cylinder barrel of the right cylinder body 2 to the right cylinder body 2, the joint surfaces are planes perpendicular to the axis of the cylinder barrel of the right cylinder body 2, the number of the second water jackets 4 is the same as that of the cylinder barrels of the right cylinder body 2, all the second water jackets 4 are sequentially arranged along the length direction of the right cylinder body 2 and are distributed at equal intervals, one end of each second water jacket 4 is located at one cylinder barrel of the right cylinder body 2, and the other end of each second water jacket 4 is located on the joint surface of the right cylinder body 2. The joint surface of the left cylinder body 1 is jointed with the joint surface of the right cylinder body 2, and each first water jacket 3 is respectively communicated with one second water jacket 4.
