Danfoss Motor Describes The Potential Cause Ofmotor No Power
Why is themotor sometimes not motivated? Danfoss Motor explains its 14 potential causes
1, the ignition coil function is weakened
The flashover voltage between the two poles of the spark plug is lower than the rated voltage. Although the ignition coil can work as usual, the spark intensity is weakened, and the combustible mixture in the combustion chamber cannot be completely burned or burned slowly.
2, the whole group of high-voltage wires have poor electrical conductivity
Poor Conductivity of the Whole Group of High-Voltage Wires The poor wire quality includes the poor quality of the alloy wire and the poor insulation performance of the outer layer. The pulse current IN through the high-voltage electric wire has poor conductivity and the voltage strength is weakened, which also causes the combustion of the combustible i-coal gas to be incomplete or slow to burn.
3, the capacity of the electrical appliances is weakened
After the function of the capacitor is weakened, the secondary voltage is greatly reduced, so the ignition intensity is weakened, and the mixed gas is slow to burn U.
4. The gap between the two poles of the spark plug and the two poles of platinum does not meet the standard requirements.
The spark plug gap is generally 0.70-1.00 mm, and the platinum gap is generally 0.35-0.45 mm. If the gap is too large or too small and the carbon deposit between the two poles will affect the work of the spark plug, although the spark plug is in a fire, the fire is strong and weak, sometimes it does not jump, which will weaken themotor power.
5, the carburetor main oil hole is too small
The main oil quantity hole includes an adjustable main oil quantity hole. Although the main oil quantity hole is too small, although themotor is sufficient in operation, in the full load operation, the tempering door is used to enrich the mixed gas to obtain better power effect. . The choke valve is a device when themotor is started. It is not an indispensable mechanism in driving. It is not appropriate to adjust the mixture in the vehicle. Use the damper to adjust
The concentration of the mixed gas is mastered by hand. The excessively rich mixture is not completely burned, and not only does it not get good power but also consumes too much fuel.
6, ignition timing is not allowed
When the vehicle is running out of power, the driver often adjusts the distribution board to achieve pre-ignition to obtain better power effects, but often explodes during heavy load operation. When themotor has a sudden explosion, it will lose some power. When the ignition is too late, the pressure after the combustion of the combined gas cannot be fully exerted, and themotor will appear weak.
7. The oil level of the carburetor float chamber is too low or too high
When the oil level is too low, the gasoline in the carburetor spray tube is rapidly dissipated during high-speed or full-load operation, and the float chamber is not ready to be replenished quickly. As a result, the stick is weak and themotor power is reduced. If the oil level of the float chamber is too high, the fuel will be burned incompletely and discharged with the exhaust gas, or the spray nozzle gasoline will be flooded and the power loss will be lost.
8, the timing of the gas is not allowed
The intake and exhaust have their respective opening and closing angles, the intake overlap 20, the exhaust overlap 22, and the same level of intake and exhaust valve adjustment is already in advance. As a rule of thumb, an exhaust valve of 0.15-0.30 mm below the intake valve is permitted, but not excessive. If the timing of the valve timing is large, the inflation efficiency will decrease and themotor power will be affected (CA-10B type).
9, bad air filter
The air must be filtered, and the amount of air is not included in the model and filter type, the filter is dirty, the filter deposits too much oil, the filter cover sinks, the lining is reversed, and the air passage is too long or blocked. Will be insufficient, the pressure of the cylinder will decrease, and themotor power will also decrease.
10, the compression ratio drops
Poor cylinder sealing results in a drop in cylinder pressure. Especially when the valve closing is not strict, themotor power is more significant.
11, camshaft cam wear too much
Excessive amount of extension of the cam top surface will be reduced, which affects the cylinder’s aeration coefficient. If the positive and negative anomalies of the cam rotation angle are large, the valve timing is not uniform, which makes themotor work unstable.
12,motor heat dissipation is poor
Various abnormalities in the radiator cause themotor to lose power due to overheating. Excessive heating of the components in the combustion 9 causes a sudden explosion of the mixture. When the mixture is heated and expanded, the aeration coefficient is lowered, the gas density is decreased, and the cylinder pressure is decreased, and themotor power is lowered.
13, the impact of the season onmotor cooling
Poor heat dissipation from themotor or too cold a cylinder temperature can affect the power of themotor. When themotor temperature is lower than 60 °C, the oil in the cylinder wall is too thick, and the sliding parts are also thickened, and the movement of the machine is blocked to causemotor power loss.
14. Themotor bearing part is too tight. The bearing part refers to the main bearing, the connecting rod bearing and the cam bearing, and the bearing part, especially the main bearing part, is too tight. The power loss to themotor is large.
