Abstract

The invention discloses an engine, and belongs to the field of mechanical engineering. The engine comprises an air cylinder body; the air cylinder body comprises multiple air cylinders, and the cylinder diameter of each air cylinder is 175 millimeters; the multiple air cylinders are symmetrically arranged in a V shape; the multiple air cylinders particularly comprise 8 air cylinders or 12 air cylinders or 16 air cylinders or 18 air cylinders or 20 air cylinders; and a four-stroke engine is adopted as the engine, and each stroke of the four strokes is 190-215 millimeters. According to the engine, the cylinder diameter of each air cylinder is 175 millimeters, therefore, the engine is small in size, low in mass and large in power density, and the performances of the engine are good. The engine is suitable for petroleum drilling.

Description

technical field [0001] The invention relates to the field of mechanical engineering, in particular to an engine. Background technique [0002] Since the founding of New China, through the hard work of petroleum machinery workers, my country's petroleum drilling rig manufacturing industry has grown from scratch, from small to large, and has made great achievements and development. Among them, the engine is the power source of petroleum drilling rigs. [0003] At present, the engines used for oil drilling rigs are mainly 190 series engines. The cylinder block in this series of engines is composed of 12 or 8 cylinders arranged symmetrically in a V shape, and the bore diameter of each cylinder is 190mm (mm). [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0005] Power density is a comprehensive index to measure the performance of the engine, specifically refers to the ratio of the...
