The invention provides a single cylinder engine testing device capable of changing a cylinder diameter and a journey. The single cylinder engine testing device capable of changing the cylinder diameter and the journey comprises an air cylinder, a piston which is located in the air cylinder, a connecting rod which is connected with the piston, a bent axle which is connected with the connecting rod, a transmission mechanism, an intake and exhaust cam shaft, a fuel oil cam shaft, a air cylinder block, a bent axle box body, an intake and exhaust cam shaft box and a fuel oil cam shaft box. The intake and exhaust cam shaft and the fuel oil cam shaft are connected with the bent axle through the transmission mechanism. The intake and exhaust cam shaft is arranged in the intake and exhaust cam shaft box. The fuel oil cam shaft is arranged in the fuel oil cam shaft box. The intake and exhaust cam shaft box and the fuel oil cam shaft box are respectively connected with the air cylinder block through a second connecting piece. The air cylinder is arranged in the cylinder block. Cam shafts are arranged in the cam shaft boxes, and the bent axle is arranged in the bent axle box. The air cylinder is connected with the bent axle box body through a first connecting piece, and the cam shaft boxes are connected with the air cylinder body through the second connecting piece. The single cylinder engine testing device is compact in structure, simple in arrangement, convenient to assemble and disassemble, low in developing cost of the whole engine and short in lead time.
Description
technical field [0001] The invention relates to a single-cylinder engine test device, in particular to a single-cylinder engine test device with variable bore and stroke. Background technique [0002] In recent years, compared with the whole machine, the single-cylinder engine test device has the advantages of eliminating the mutual interference between cylinders and obtaining more accurate working process test data, convenient disassembly and assembly of parts, and faster test speed. It has played an increasingly important role in the development process, especially the development of high-power diesel engines with cylinder diameters greater than 150mm. Through the use of single-cylinder simulation machine technology, the performance of multi-cylinder machines can be accurately predicted, saving the time and cost of product development. [0003] The single-cylinder engine test device is mainly responsible for combustion development, key component verification and special t...
