Is the difficulty of starting a two stroke engine related to the spark plug?

First, the phenomenon of the problem.

Generally, spark plug problems will lead to poor engine work, such as difficult starting, unstable idling, poor acceleration, urgent refueling and tempering, excessive exhaust gas, and increased fuel consumption. If the carbon deposition in the engine is serious, the valve will not be tightly closed, so that a cylinder will not work completely because there is no cylinder pressure, and even stick the valve to prevent it from returning. At this point, the valve and piston will interfere with the movement, which will eventually damage the engine.

It can be seen that the impact of carbon deposits on the engine is very large.

Second, the solution.

1.When unplugging the high-voltage wire joint, it should be gentle, and the spark plug insulator should not be shaken vigorously during operation, otherwise the spark plug sealing performance will be damaged.

2.The engine can be disassembled only after cooling, when the spark plug to be removed is loosened, blow the dirt around the spark plug one by one with a thin hose, and the dirt falls into the combustion chamber after the spark plug is unscrewed out.

3.The screw area, spark plug electrode and gasket must be kept clean, dry and free of oil stains, otherwise it will cause leakage, air leakage, spark weakening and other failures.

4.When installing, first use the sleeve to align the spark plug with the screw hole, gently screw it in by hand, screw it to about 1 2 of the full length of the thread, and then tighten it with an afterburner lever. If the hand feeling is not smooth when twisting, you should exit to check whether there are any entrained impurities in the screw mouth or thread, and you must not blindly tighten it, so as not to damage the screw hole and affect the cylinder head, especially the aluminum alloy cylinder head.

5.It should be tightened according to the required torque, too loose will cause air leakage, too tight will make the gasket lose elasticity, and it will also cause air leakage. Since the tapered spark plug does not use a gasket, it is particularly important to comply with the tightening torque.

6.When the carbon deposit and oil accumulation on the spark plug are not very serious, you can soak it in gasoline or kerosene and acetone solvent, and after the carbon deposit is softened, brush the carbon deposit on the electrode and the porcelain core and the cavity of the shell with a non-metallic brush, and dry it with compressed air. After cleaning, the spark plug is checked for clearance.

3. Preventive methods.

After completing the above, the installation test will be carried out, and the owner will be reminded to do regular maintenance to keep the oil and gas circuits clean; It is recommended to clean the air grid every 4000-8000km (according to the use of the vehicle and the actual situation) (replace it according to the actual situation), clean the throttle once, and clean the fire nozzle; Every 15,000-25,000km (according to the use of the vehicle and the actual situation), clean the intake pipe, throttle combustion chamber and related oil circuits, check the gasoline grid and replace it according to the situation; Avoid idling and stopping for a long time, avoid turning off the engine immediately after high-speed driving, avoid high-speed driving immediately after starting, and avoid low-speed gear shifting.

Hello, bad spark plugs and engine starting can have a big impact.

The main reasons for the spark plug are not good quality or the spark plug model is not suitable, the burning mixture oil is not good or not the special oil for the two-stroke, the high voltage is weak, the gasoline oil quality is not good, and the carbon deposit is too much.

Yes, the two-stroke engine always burns the spark plug, because it is a premixed combustion, the organic oil in the gasoline, it is easy to save the spark plug, the oil in the gasoline is less, or adjust the pump oil volume of the oil pump, so as to save the spark plug, but the engine is broken quickly, supplement, the spark plug has carbon deposits, remove it and burn it with fire, scrape off the carbon deposits can be reused,

Each stroke was ignited, and once the four-stroke engine was exhausted, and the spark plug did not work. The reason for the fuel, the fuel of the two-stroke engine has a lot of oil components, which is used to lubricate the engine, and this mixed oil is easy to produce carbon deposits, resulting in slight leakage in the early stage of the spark plug.

The crankshaft rotates once, and the piston moves up and down twice to complete a working cycle (intake, compression, combustion, exhaust) of the engine.

An engine that completes a duty cycle in two strokes. The crankshaft of the two-stroke engine rotates once, and the engine works externally once.

The first stroke: the piston completes two actions from top dead center to bottom dead center.

1.The spark plug ignites, and the work is done – exhaust.

2.Turn off the intake air and press the mixture from the lower part of the piston into the crankcase, and from the top of the piston back into the cylinder.

Second stroke: The piston goes from bottom dead center to top dead center. Complete two actions.

1.Turn off all intake and exhaust gases and compress the potato Liangxiao mixture.

2.To complete a work cycle, the piston needs to move two strokes, so it is called a two-stroke.

There are three holes in the engine cylinder block, namely the air intake, exhaust and vent, which are closed by the piston at a certain moment. Its working cycle consists of two strokes.

1.First stroke: the piston moves upwards from the bottom dead center, and after the three holes are closed at the same time, the mixture entering the cylinder is compressed; When the air intake hole is exposed, the combustible mixture flows into the crankcase.

2.Second stroke: When the piston is compressed to near the top dead center, the spark plug ignites the key cherry blossom combustible mixture, and the gas expansion pushes the piston down to do work.

At this time, the air intake hole is closed, and the combustible mixture sealed in the crankcase is compressed; When the piston approaches the bottom dead center, the exhaust hole is opened, and the exhaust gas is flushed out; Then the vent is opened, and the pre-pressurized combustible mixture is rushed into the cylinder to expel the exhaust gases and carry out the ventilation process.

Hello, the second let the annihilation stroke engine is two strokes, one intake compression, one Tanzhou exhaust, generally used for motorcycles to start the beam changing machine more, car engines are generally four-stroke, I am happy to answer for you!

First stroke: the piston from top dead center to bottom dead center. Complete two actions.

1.The spark plug ignites, and the work is done – exhaust.

2.Close the intake air and press the air mixture from the lower part of the piston to the axle box, and then enter the cylinder from the top of the piston.

Second stroke: The piston goes from bottom dead center to top dead center. Complete two animations.

1.Turn off all intake and exhaust air and compress the mixture.

2.To complete a work cycle, the piston needs to move two strokes, so it is called a two-stroke.

A two-stroke engine is an engine made using the principle of two-stroke erection, which is usually used in low-power equipment.

Hello dear, the two-stroke engine always burns the spark plug because the quality of the spark plug is not good or the spark plug model is not suitable, the burning mixture oil is not good or not the special oil for the two-stroke, the high voltage is weak, the gasoline oil quality is not good, and the carbon deposit is too much, first of all, you need to check whether there is a leakage on the ignition line that causes ignition, and the energy is too large, so the spark plug caused by the need to check the hail to check the ignition coil. Do you have any questions that I would like to answer for you?

Two-stroke engines and four-stroke engines are more durable, depending on their quality, as well as their use and maintenance. From the perspective of engine working principle alone, two-stroke engine and four-stroke engine have their own advantages and disadvantages, both have advantages and disadvantages to the reputation of durability, so only from the working principle of the two engines, it is impossible to determine which engine is more durable, and it is not as important as their own quality.

The advantage of the two-stroke engine is that the structure is simple, and the engine has few parts, especially the parts of the valve system, so that the probability of its failure and parts damage may be less. However, the two-stroke engine is also conducive to reducing engine failures due to the faster frequency of work, and the engine is not perfect because the engine burns mixed oil, and it is also more prone to carbon deposits. In addition, the two-stroke engine is more fuel-intensive than the four-stroke engine of the same displacement, in addition to burning more gasoline, the oil is usually mixed with gasoline in a certain proportion and burned, so as to provide lubrication for the crankshaft connecting rod of the engine and the piston moving part of the cylinder block.

Compared with the two-stroke engine, the structure of the four-stroke engine is much more complex, and because the structure is complex and there are many parts, the possibility of failure and damage to the parts is relatively more. However, the working principle of the four-stroke engine is more reasonable and stable than the two-stroke engine, and the lubrication efficiency of the engine lubrication system is also higher, and due to the good lubrication and heat dissipation, the engine work frequency is not as high as that of the two-stroke engine, so from this aspect, it is conducive to reducing the failure rate and the four-stroke engine is more fuel-efficient, and the exhaust emissions are also cleaner.

Therefore, in the end, which engine is durable, the most important thing is its own quality, as well as the usual use and maintenance standards.
