Problems solved by technology

However, since the FRP sleeve outer wall portion is fixed under pressure via the end of the liner portion, the liner portion is easily subjected to pressure that deforms the shape of the hole
Therefore, if the cylinder liner portion is made thinner to reduce the size and weight of the engine, the fact that the hole is easily deformed hinders the reduction in size and weight of the engine

Embodiment Construction

[0068] As the first exemplary embodiment of the present invention, figure 1 The perspective view shows the structure of the engine body 2 using the four-cylinder internal combustion engine of the present invention. This engine main body 2 is constructed by stacking the main body cylinder block 4, the outer cylinder block 6, the gasket (seal) 7 and the cylinder head 8, such as figure 2 As shown in the exploded perspective view.

[0069] The main cylinder block 4 and the outer cylinder block 6 are assembled together, such as image 3 Perspective view and Figure 4 As shown in the top view, the cylinder block 10 is formed.

[0070] The main cylinder block 4 is integrally cast from aluminum alloy or magnesium alloy. The main body cylinder block 4 includes four cylindrical cylinders 12 formed at the top, a skirt 14 formed at the bottom, and an outer wall mounting part 16 formed between the cylinder 12 and the skirt 14. A plurality of ribs 18 and 20 are provided on the outer sides of ...

Abstract

The present invention relates to a cylinder block, a cylinder head and an engion main body. The cylinder block (10) is such that a main body cylinder block (4; 404) and an outer cylinder block (6; 406) are molded separately. As a result, the portion of the die which is used to mold a water jacket (50; 450) does not need to be made thin, thereby increasing the life of the die. Further, cylinders (12; 412) are of a simple shape and the pressure in the axial direction of the cylinder (12; 412) is able to be dispersed substantially evenly between the cylinders (12; 412) and the outer cylinder block (6; 406), thus enabling the cylinders (12; 412) to be thin. Accordingly, there is an increased degree of freedom in design of the portion which forms the water jacket (50; 450). The water jacket (50; 450) and the cylinders (12; 412) can therefore both be made sufficiently thin, thereby contributing to a decrease in both the size and weight of the engine.

Description

Technical field [0001] The invention relates to a cylinder block, a cylinder head and an engine main body of an engine. Background technique [0002] In the cylinder block of a gasoline engine or a diesel engine or the like, a water jacket for circulating coolant is formed around the cylinder. As an example of a cylinder block structure in which a water jacket is formed around the cylinder, Japanese Patent Laid-Open No. 5-296103 (page 2-3, figure 1 ) Discloses an engine in which a cylinder wall and a water jacket wall are integrally formed, and then a resin casing is mounted on the water jacket wall. [0003] At the same time, Japanese Utility Model Publication SHO 63-98465 (pages 6-7, figure 1 ) Discloses an engine in which a water jacket forming plate surrounds a cylinder body in which a cylinder block and a cylinder head are integrally formed, and is fixed from the outside by welding. [0004] In addition, Japanese Utility Model Publication SHO 61-76149 (pages 3-4, figure 2 ...
