Embodiment Construction
[0022] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.
[0023] Unless otherwise expressly stated otherwise, throughout the specification and claims, the term "comprising" or its transformations such as "comprising" or "including" will be understood to include the stated elements or components, and not Other elements or other components are not excluded.
[0024] Such as Figure 1 to Figure 3 As shown, the cylinder block of the diesel engine according to the specific embodiment of the present invention includes a main body 1 and a plurality of cylinder bores 17. The plurality of cylinder bores 17 are directly formed on the main body 1, without installing cylinder liner parts, which helps reduce the engine High vibration and noise, improve the reliability of use, reduce the manufac...

Abstract
The invention discloses a cylinder block of a diesel engine. The cylinder block comprises a body and a plurality of cylinder holes, the multiple cylinder holes are directly machined and molded in the body, cooling water sleeves are arranged on the peripheries of the cylinder holes, and two water ways which are formed in a machining manner and extend from the top face of the body downwards are formed between every two adjacent cylinder holes, wherein the two corresponding water ways are intersected, and the lower ends of the two corresponding water ways are communicated with the cooling water sleeves of the corresponding cylinder holes. According to the cylinder block, the cylinder holes and the body are integrated together, the part between every two cylinder holes is cast into a solid, the water ways are formed in the machining manner, the cylinder center distance is decreased, the length, the weight and the cost of the cylinder block are reduced, distribution of the diesel engine is more compact, and the reliability of the cylinder block is improved.
Description
Technical field [0001] The invention relates to the field of engines, in particular to a cylinder block of a diesel engine. Background technique [0002] The cylinder block is the main body of the diesel engine, which connects each cylinder and the crankcase into one body, and is a support frame for installing pistons, crankshafts, and other parts and accessories. [0003] Traditional multi-cylinder diesel engine cylinder blocks have the following characteristics: 1. Generally, wet cylinder liners are used, and each cylinder uses an independent cylinder liner, but more parts are used; 2. Or a dry liner structure is used, which is one of the two cylinders. The water-passing water jacket between the two cylinders is directly cast. However, due to the requirements of the casting process, the water-passing water jacket between the two cylinders is often thicker, resulting in a larger cylinder center distance of the engine, a larger body length, and a relative weight. Larger; 3. In ord...
