Gasoline Generator Increased The Concentration Of The Mixture
Jun 13, 2017

Gasoline engine engine corrosion refers to the metal parts by the role of the surrounding medium caused by the phenomenon of failure.

Gasoline generator generator corrosion types include chemical corrosion, cavitation and electrochemical corrosion of three. The corrosion of the engine in the gasoline generator is mainly chemical corrosion and cavitation.

1. Engine chemical corrosion of gasoline generators

Metal parts and media directly caused by the chemical effect of the failure caused by chemical corrosion. The corrosion product is directly generated at the site where corrosion occurs and a surface film is formed on the metal surface. The properties of the film determine the rate of chemical corrosion, such as membrane integrity tight, it is conducive to the protection of metal parts and slow down the corrosion. In the diesel engine, the cylinder liner wall by the gas in the role of acid gas corrosion caused by chemical corrosion.

2. Gasoline generator engine cavitation

Cavitation (also known as cavitation) is a failure form when the part is in contact with the liquid and has a high frequency impact. This failure is characterized by the presence of pitting and pinholes in the local area, and the clustered honeycomb clusters in the severe area.

The diameter of the hole can reach Imm or even a few millimeters, the depth can penetrate the parts. Wet cylinder liner outer wall, sliding bearings and so may be due to the occurrence of cavitation and damage. Due to the strengthening effect of the gasoline engine,Gasoline generator the phenomenon of cavitation of the cylinder liner is serious, and the cavitation has become one of the important factors affecting the life of the cylinder liner.

3. Electrochemical corrosion of gasoline engine

Metal surface and the surrounding medium electrochemical action and the current generated by the corrosion known as electrochemical corrosion.

A spark plug how to check and clean up:

Spark plug check, processing in three steps:

The first step: check the spark plug of the carbon situation, if the carbon with copper brush clean.

Step 2: Check the gap of the spark plug. Standard clearance of 0.7-0.8MM, about three business card thickness. If the gap is not correct, and can be adjusted.

The third step: check the spark plug ignition performance, sparks with a strong blue spark is better.

Second, start the damper switch what is the matter?

Because the engine is in the cold when the start off the throttle, so that the air into the carburetor to reduce the concentration of the mixture, then the engine is easier to start. If the cooler at this time to open the damper, the mixture is easy to adsorb in the inlet wall, resulting in atomization is not good, it is not easy to start.

Because the engine is in the heat engine to start to open the damper,Gasoline generator so that the proportion of the mixture into the combustion chamber to normal, can easily start. When the throttle is closed, the air entering the carburetor is reduced, greatly increasing the concentration of the mixture, which can cause it to be easy to start.

Third, long (more than three months) do not use, how to carry out custody?

1. The tank and carburetor in the gasoline to let go;

2. The oil in the crankcase to discharge;

3. Add a new oil to the oil level of oil cap;

4. Close the choke, and pull the starter handle to the point where there is resistance;

5. Wipe the unit clean, cover with a carton or plastic cover to prevent dust;

Fourth, can not generate electricity:

   1. wiring error; check by line diagram, correct

   2. The main generator or exciter of the excitation winding connected to the wrong, resulting in polarity is not right; often occurred in the replacement of the excitation winding caused by wiring errors. Should be checked and corrected;

   3. Rotating silicon rectifier components breakdown short circuit, positive and negative are conduction; with a universal meter check rectifier components positive and negative resistance, replace the damaged components;

   4. The main generator field winding is broken. With a multimeter to check the main generator excitation winding, the resistance is infinite, should be connected to the excitation line;

   5. The main generator or exciter of each winding has a serious short circuit; armature winding short circuit, generally have a superheat, excitation winding short circuit, by its tributary resistance to determine the value. Replace the damaged windings;
