Abstract

The invention discloses a V-shaped 12-cylinder cylinder block, comprising: a V-shaped top, the V-shaped top includes a plurality of cylinders arranged in two rows on the left and right, the cylinders are provided with cylinder liners, and the angle between the two rows of cylinders on the left and right is 90° ; Two bottoms, each bottom is provided with a plurality of U-shaped reinforcing ribs; and a plurality of V-shaped reinforcing plates, each V-shaped reinforcing plate is arranged between two adjacent cylinders, and the V-shaped reinforcing plate is arranged along the V-shaped The width direction of the 12-cylinder cylinder block extends to the inner wall of the V-shaped 12-cylinder cylinder block, and the height of the V-shaped reinforcement plate reaches the middle of the cylinder liner; there are two crankcase ventilation channels on the V-shaped reinforcement plate, two The crankcase ventilation passages are symmetrically arranged, and the two crankcase ventilation passages are connected front and rear along the direction of the crankshaft. The two crankcase ventilation passages are connected to each other, and each crankcase ventilation passage is respectively connected to the crankcase of each cylinder; one of the crankcase An oil-gas separation structure cover plate is arranged above the end of the ventilation channel.

Description

technical field [0001] The present invention relates to a cylinder block structure, in particular to a V-shaped 12-cylinder cylinder block. Background technique [0002] NVH, namely Noise, Vibration and Harshness (abbreviation of Noise, Vibration, Harshness). NVH performance is a comprehensive indicator to measure the quality of automobile manufacturing. It gives the most direct feeling to automobile users. Statistics show that about 1 / 3 of the failure problems of the whole vehicle are related to the NVH problem of the vehicle. Therefore, Improving the NVH performance of vehicles is one of the research and development priorities of major vehicle manufacturers and parts companies. [0003] The cylinder block of the existing V-shaped high-power engine has an upper V-shaped part and two bottoms, and each bottom is provided with a cavity inside. However, the existing V-shaped cylinder block structure, especially the existing V-shaped The 12-cylinder cylinder block has a low de...
