Embodiment Construction

[0023] Below in conjunction with accompanying drawing, the present invention will be further described:

[0024] Figure 3 to Figure 5 Shows a tool for detecting the volume of the engine piston combustion chamber, including a cylindrical barrel 2, a floating plate 3 and a clamp 4; in this embodiment, the floating plate 3 includes a rectangular plate 32 and an arc-shaped plate 31; the cylindrical barrel 2 is provided with The opening slot 21, the rectangular plate 32 is compatible with the opening slot 21, that is, when the arc plate 31 is placed over the engine piston combustion chamber, the rectangular plate 32 passes through the opening slot 21 and is fixed by the clamp 4; in order to ensure the accuracy of the measured volume and the piston does not deform, the clamp 4 is set on the rectangular plate 32 and needs to be properly tightened to fasten the floating plate and the cylinder; A rectangular plate 32 protrudes from the center; the height of the rectangular plate 32 i...

Abstract

The invention relates to a tooling and structure for detecting the piston combustion chamber volume of an engine. The tooling includes a cylinder, floating plates, and a hoop; opened grooves are formed in the cylinder; the floating plates include a rectangular plate and an arc plate; and the rectangular plate matches the opened grooves, the loop is clamped on the rectangular plate so as to fasten the floating plates and the cylinder. The tooling for detecting the piston combustion chamber volume can measure the volume before a piston is installed, is easy to operate, is low in cost, is high in utilization rate, and can adapt to different types of engines.

Description

technical field [0001] The invention belongs to the technical field of engine combustion chamber detection components, and in particular relates to a tool and structure for detecting the volume of an engine piston combustion chamber. Background technique [0002] The engine is the heart of a car, which converts chemical energy into heat energy, and then converts heat energy into mechanical energy to output power to drive the car; the compression ratio is very important to the engine and directly affects the performance of the engine such as combustion, power, economy, and emissions Index; the compression ratio is equal to the total cylinder volume Va divided by the combustion chamber volume Vs, and the piston combustion chamber volume is the most important part of the combustion chamber volume; due to the consideration of combustion, power, economy, and emissions, the types of pistons are becoming more and more The shape of the top surface of the piston is becoming more and ...
