Problems solved by technology

Insufficient cylinder pressure usually leads to problems such as ignition difficulty, engine jitter, and increased fuel consumption. The main causes of insufficient cylinder pressure include aging seals, worn piston rings, poor sealing of valves, and poor sealing of cylinder gaskets, etc.
In the actual maintenance process, the overhaul of the cylinder can only check whether the air pressure in the cylinder is within the normal pressure range through the cylinder pressure gauge, and it is impossible to efficiently find the specific location and cause of the air leakage in the cylinder through the existing tools and instrumentation equipment
Usually, the problem of air leakage of the cylinder must be solved by dismantling the engine for maintenance, which will result in long maintenance hours and high maintenance costs. Therefore, a detection device for the air leakage position of the engine cylinder is proposed to solve the above problems

Abstract

The invention discloses an air leakage position detection device for an engine cylinder. The detection device comprises a smoke generation device and a smoke detection device, and is characterized inthat the smoke generation device comprises a smoke box and a pressure measurement meter, an outlet of the smoke box is sequentially connected with the pressure measurement meter and the cylinder, andsmoke can be input into the cylinder; the smoke detection device comprises an endoscope, an LED lamp and a buzzer alarm, and the smoke detection device can extend into the air cylinder and is used fordetecting the smoke condition in the air cylinder and the aging or cracking condition of all parts; the detection device designed by the invention can realize rapid detection of in-cylinder leakage.

Description

technical field [0001] The invention belongs to the technical field of automobile maintenance, and in particular relates to an air leakage position detection device for an engine cylinder. Background technique [0002] With the increase of the number of cars, the car maintenance technology is constantly improving, but engine fault troubleshooting has always been a difficult point in the maintenance technology. The cylinder is an important part of the engine, and normal cylinder pressure can ensure the normal operation of the engine. Insufficient cylinder pressure usually leads to problems such as ignition difficulty, engine jitter, and increased fuel consumption. The main causes of insufficient cylinder pressure are aging seals, worn piston rings, poor sealing of valves, and poor sealing of cylinder gaskets. In the actual maintenance process, for the maintenance of the cylinder, the cylinder pressure gauge can only be used to detect whether the air pressure in the cylinder ...
