Why does a Honda stall after starting for a few seconds when it's cold?

Introduction Why does a Honda stall after starting for a few seconds when it's cold? Why does it start and then turn off after a few seconds? 1. The fuel mixture is too rich. Unburnt residue will accumulate on the spark plug electrode

Why does a Honda stall after starting for a few seconds when it's cold?

Why is it starting and then died after a few seconds?

1. The fuel mixture is too rich. The non -burned parts remaining will accumulate on the electrode of the ignition candle and will be charred, causing an abnormal flashing of the ignition candle until it is damaged by carbonization. The reasons why the fuel mixture is too rich are generally that the carburetor oil level is too high, that the main air volume hole in the carburetor is clogged and that the air filter element is seriously obstructed. In addition, the carburetor starter is blocked and cannot be completely open, or the enrichment valve does not work properly, which is also the reason why the fuel mixture is too rich.

2. Engine oil leak. During the operation of the engine, if blue or black smoke is issued by the exhaust pipe, this indicates that an excess of HEngine oil has entered the cylinder, which will cause the spark plug electrode to produce a large amount of carbon deposits or moisten it. by engine oil and unable to produce sparks. This phenomenon is commonly referred to as engine oil channeling. For two-stroke engines, check whether the oil volume of the oil pump is too large and whether the rod sleeve seal and check valve are defective. For four-stroke engines, check the piston rings on the piston, especially the oil ring, whether it is worn or not. Then remove the intake valve and check for carbon and wet grease deposits on its head and back. If the valve and valve guide are severely worn, the valve guide seal is hardened, or the seal lip is excessively worn, the mounting gap will be too large and the effect of The seal will be lost. These twoAbnormal situations will eventually cause oil in the valve rocker arm chamber to be drawn into the cylinder along the valve stem during intake air summing, causing oil combustion. In this regard, the valve guide, oil seal or valve must be replaced respectively depending on their wear.

3. In the ignition system, the magneto is demagnetized, the wire connections inside the ignition coil and the electronic ignition, the generator output end and the coil input end are demagnetized. The ignition is loose and the ignition timing is incorrect. If it is not properly timed, it will affect the ignition performance, and poor ignition performance will directly cause carbon deposits.

4. Pay attention that the spark plug model and calorific value comply with the instructions for use. If the calo powerselected gear is one or two gears lower than that specified in the instruction manual, the heat cannot be dissipated in time, causing abnormal combustion and possibly melting the spark plug electrode and causing burns. premature damage. When the spark plug itself is installed and used, some defects are not easy to find and also affect the ignition performance. For example, if the spark plug is poorly sealed, if the spark plug is not firmly fixed, if the spark plug insulator is cracked, etc., it should be adjusted or replaced in time . 5. If the crankcase oil is overfilled and the breather pipe is blocked, the pressure in the crankcase will increase and the crankcase will not be balanced.

The ventilation of the diesel generator room includes two parts: daily ventilation and working ventilation.

Daily breakdown: the numberof ventilations in the engine room of air-cooled and water-cooled generators should be 6 times, and the number of ventilations in the oil storage room should not be less than 3 times. For computer rooms that use gas fire suppression systems, after a fire, this ventilation system is responsible for exhausting indoor exhaust gases, but it is not accidental ventilation. To ensure personal safety, it is recommended to set the start button for accidental ventilation.

Working ventilation: Water-cooled diesel generators must consider the amount of air required for operating oxygen consumption; Air-cooled generators have a large volume of cooling air and generally use a natural air intake. The diesel engine has its own air intake. fan pressureEmissions, but the height of prfan pressure of diesel generator is only about 150 Pa. When the shaft resistance is large, a fan should be added to overcome the shaft resistance. Generally, if the resistance of the air inlet shaft is. large, an inlet fan is added; if the resistance of the exhaust shaft is large, an exhaust fan is added;

The diesel generator room uses a gas fire extinguishing system. Solenoid valves should be installed on the air inlet and exhaust channels. When a fire occurs in the diesel generator room and gas fire extinguishing is triggered, these valves will be closed. in a chain to ensure the extinguishing effect.

Diesel generator exhaust is a pressurized exhaust with high combustion gas temperature and high air flow velocity. Combustion gases must be vented at high altitude. The driverIt must be thermally insulated and equipped with a shock-absorbing support. should be installed.

Diesel generator rooms should pay attention to ventilation and smoke exhaust, otherwise it will affect the use of the generator and cause damage to the generator. For businesses that cannot afford power outages, generator damage is very serious. bad thing.
