Detailed explanation of combustion engine maintenance

1、 The structure and working principle of a combustion engine

The combustion engine is the core component of hot water equipment such as hot water boilers and steam boilers. Its main function is to fully mix fuel and air, and then undergo thermal reactions under high temperature and pressure conditions, converting thermal energy into mechanical or thermal energy. The main structure of a combustion engine includes burners, igniters, rockets, and control systems.

The working principle of a combustion engine is to mix fuel and air before ignition, producing high-temperature and high-pressure combustion gas, which is discharged into a boiler or hot water equipment to achieve the purpose of heating. Fuel can be diesel, natural gas, liquefied gas, etc. With the increasing awareness of environmental protection, more and more combustion engines are now using clean fuels.

2、 Common faults and maintenance methods

1. Igniter malfunction

The igniter is an important component of a combustion engine, whose main function is to ignite the mixed gas and start the combustion engine. Common igniter faults include electrode aging, weak spark, etc. For this type of fault, professional testing instruments can be used to check whether the electrode electrical is normal, and the electrode or ignition cable can be replaced in a timely manner to ensure the normal start of the combustion engine.

2. Burner malfunction

Burner failure is one of the most common faults in combustion engines, including blocked fuel pumps and nozzles. For this type of malfunction, professional fuel cleaning agents can be used to clean the interior of the burner, as well as components such as nozzles and fuel pumps.

3. Control system malfunction

The control system is the brain of the combustion engine, and common faults include sensor failures, controller aging, and so on. For this type of fault, professional testing instruments can be used to check whether the controller circuit is normal and replace the faulty components in a timely manner.

3、 Maintenance Techniques

1. Pay attention to maintenance

Regular maintenance of the combustion engine can reduce the occurrence of malfunctions. The maintenance content includes cleaning the interior of the burner, adjusting the position of the igniter, replacing aging electrodes, and checking the controller circuit.

2. Pay attention to safety

When repairing the combustion engine, it is important to pay attention to safety. Before maintenance, the power and gas must be cut off to ensure that the combustion engine is in a safe state. Wear safety helmets, gloves, and other protective equipment during operation to avoid safety accidents.

Summary: Combustion engine maintenance is a meticulous and complex task that requires mastering certain maintenance skills and knowledge. I hope this article is helpful for readers to understand the methods and techniques of combustion engine maintenance, so that your combustion engine can always maintain normal operation.
