Embodiment Construction

[0037] The present invention is described in further detail below:

[0038] The invention discloses a 12-cylinder water-cooled diesel engine. The engine includes a crank connecting rod mechanism, a gas distribution mechanism, a transmission mechanism, a cooling system, a lubrication system, a fuel supply system, an intake and exhaust system, an electrical system and a starting mechanism arranged on a fixed part. .

[0039] The stationary part of the present invention includes a crankcase 101 , an oil pan 102 , a flywheel housing 103 , an accessory bracket 104 , a cylinder liner 105 , a cylinder head 106 , and a crankcase breather 107 connected to each other. The overall structure of the engine adopts a V-shaped included angle of 90°, the diameter of the cylinder on the crankcase 101 is 132mm, the stroke of the piston is 145mm, and the distance between the cylinder centers is 165mm. The complete machine of the present invention adopts the structure of the inner oil channel and...

Abstract

The invention discloses a 12-cylinder water cooling diesel engine. The engine comprises a crank connecting rod mechanism arranged on a fixed part, a gas distribution mechanism, a transmission mechanism, a cooling system, a lubricating system, a fuel supply system, an intake / exhaust system, an electric system and a starting mechanism. The water cooling engine widens the power range, increases the power from traditional 195-499 kW to 780 kW, preferably exerts the characteristics of high power, small size, compact structure and low fuel consumption of the series of diesel engines, adapts to the market demands, satisfies the use requirements of users, is better in market competitiveness, can be applied to such fields as engineering machinery and generator sets, and widens the application field of 132-series engines.

Description

technical field [0001] The invention relates to the technical field of engine design and manufacture, in particular to a 12-cylinder water-cooled diesel engine. Background technique [0002] Engines are widely used and are mainly used in final supporting products. For example, high-power high-speed diesel engines are mainly used for heavy-duty vehicles, large buses, construction machinery, ships, generator sets, etc. [0003] The existing 132 series (that is, the cylinder diameter is 132mm) water-cooled diesel engine has only two types of cylinders: 6 cylinders and 8 cylinders. The cylinders are divided into two groups of left and right and are installed on the same crankshaft alternately. Or 70 degrees) to form a V-shaped structure, the advantages are compact size and small vibration. [0004] However, the existing 132 series water-cooled diesel also has the disadvantage of small power coverage. The coverage is usually 195-440KW, and the maximum power can only reach 490kW....
