The 170 gasoline engine starts normally, but it is weak after starting, and the speed is fast and sl

This problem is the problem of the oil circuit, check whether the oil circuit is normal, if the oil circuit is normal, that is, the carburetor float switch is not flexible, and the oil in the oil storage cylinder is too little, so that the atomization ratio is uneven, so that the speed is fast and sometimes changing.

Traveling car, can you press the accelerator pedal to be stable. If you can, you look for the throttle and idle motor.

What is the reason for the weakness of the 170F gasoline engine. Sometimes I ask the master what is the reason for the weakness of the 170F gasoline engine, and the exhaust valve is spitting fire, unable to increase speed, and abnormal operation. Troubleshoot carburetor issues. Sometimes the refueling and turning off the ignition also bring a bit of reversal,

What is the reason why the 170 gasoline engine starts to lose strength after a period of time, and then turns off.

170 gasoline engine with a period of time began to crack the beam, and then turned off what is the reason, 1, the oil sensor Tan Yuan only fault (you can try to disconnect the oil sensor) 2, the carburetor oil supply is not normal (replace the carburetor) 3, the mixing and training ratio is not right (you can try to adjust the degree of damper opening) I hope it can help you.

1 The battery voltage is too low. 2 If the battery voltage is normal and this fault occurs, accompanied by the "click" sound, it may be that the battery column is loose or oxidized for a long time, resulting in poor contact (the use of maintenance-free batteries is most likely to cause this fault if it is not maintained for a long time), and sometimes it will cause the starter to suddenly not rotate. 3. The carbon brush is too worn, or the spring elasticity of the carbon brush is too weak (the probability of occurrence is low), resulting in poor contact of the carbon brush, which often causes the starter to rotate slowly and weakly from time to time.

4. Long-term neglect of maintenance of the starter, so that the armature copper sleeve is worn excessively, causing the armature to rub against the stator core, which often causes the starter to gradually weaken.

Hello, glad to answer for you. There are many reasons for this.

If it is only slow when starting, it is normal after starting. It may be that the starting capacitor is not matched, or the motor design is inherently like this (depending on the site design), or it may be that the starting time is too long due to factors such as excessive load resistance. If the rotational speed is slow after starting, it may be that the problem may be insufficient voltage, capacitance mismatch, high rotational resistance, etc.

Reasons for the slow speed of the motor when starting: (1) The power supply voltage is too low, and the adjustment voltage should be checked. (2) If the wiring of the main and auxiliary windings is wrong, the wiring should be carefully checked and corrected.

3) The short-circuit winding of the motor is unsoldered and should be re-welded. (4) If the capacitance of the capacitor running motor is insufficient, sufficient capacity should be equipped according to the regulations. (5) The bearing lubrication is dry, and new grease should be added to the regular cleaning.

6) The motor has been left damp for a long time, and the insulation performance has not been tested before operation, and the speed of the motor winding is reduced due to the short circuit between turns after operation, and the coil should be rewound. In order to prevent the motor from tripping over current in a long starting time, the method of short-circuiting the thermal overload relay during the starting time is generally adopted, and then put into use after the start is completed. In addition, when choosing an air switch, it is necessary to pay attention to the reasonableness of the instantaneous action current value, which is greater than the starting current of the motor, so as to avoid the motor tripping the empty switch during the start-up process.

Summary. Hello, the car travels to 3000 rpm and feels that the engine sound is dull due to insufficient power, and it is normal to exceed the cylinder to work abnormally, the throttle opening is abnormal, and the carbon deposition is serious, and when the engine sound is muffled, the parts that can be checked are: 1. Check the fuel supply system, replace the gasoline filter, and clean the fuel injector; 2. Check the power supply system, whether the ignition head of the spark plug is too large, resulting in slow power jump frequency and affecting the combustion quality of the engine, it is recommended to replace it; 3. Check the air intake system, whether the air filter is dirty, whether the vacuum tube is aging and leaking, and clean the throttle; 4. Check whether the exhaust system is blocked by the three-way catalysis, which affects the smoothness of the exhaust, and it is recommended to clean or replace it.

Do you have any questions that I would like to answer for you?

The car drove to 3000 rpm and felt that the engine was not powered enough, and the sound table was muffled, and it was normal to exceed it, what caused me.

Hello, the car drove to the speed of 3000 rpm and felt that the engine sound table was dull due to insufficient power, and it was normal to exceed the cylinder working abnormally, the throttle opening was abnormal, and the accumulation of wax carbon was serious. 2. Check the power supply system, whether the ignition head of the spark plug is too large, resulting in slow power jump frequency and affecting the combustion quality of the engine, it is recommended to replace it; 3. Check the air intake system, whether the air filter is dirty, whether the vacuum tube is aging and leaking, and clean the throttle; 4. Check whether the exhaust system is blocked by the three-way catalysis, which affects the smoothness of the exhaust, and it is recommended to clean or replace it. Do you have any more questions?

It is 2700 to 3000 rpm that has this phenomenon, and everything else is normal.

How long has the car been.

10 years. Oxygen sensor check and air flow meter. Good.

Summary. Hello, dear, I am glad to answer for you, the reason why the 170 gasoline engine is difficult to start is the lack of fuel.

Hello, dear, I am glad to answer for you, the reason why the 170 gasoline engine is difficult to start is the lack of fuel.

Lack of fuel causes no fire and hunger; The battery voltage is insufficient, the voltage is too bad, and the hood is too low to enable the starter to provide sufficient speed and torque to start the engine; Mechanical failures, including fire hail plugs or ignition coil failures, that prevent the engine from igniting properly.

There is no electric start, just a hand pull.

The reason why the 170 gasoline engine stalls when it starts is that carbon deposition will cause insufficient gasoline combustion and the gearbox will run under load.

1. Carbon deposition will cause gasoline combustion to be inadequate: the engine will shake. The accumulation of carbon in the engine has a great impact on the car.

The first is to reduce the power deficit of the engine, that is, to make the power output uneven and gradually decayed, in other words, more and more powerless. The second is to increase fuel consumption and increase your financial burden.

Hello dear, I am happy to answer for you, dear hello, the reason why the 170 gasoline engine starts after a while and then starts again: 1The lack of fuel caused the town to catch fire; 2.

The battery voltage is insufficient, and the voltage is too low to make the starter provide sufficient speed and torque to start the engine; 3.Mechanical faults, including faulty spark plugs or ignition coils, that prevent the engine from igniting properly. For mechanical failures, you must go to the 4S shop in time to check and repair, troubleshoot the fault problem, otherwise it may affect the normal driving, if my help to you, you can give me a thumbs up after the end of the consultation, I wish you all the best.

After the 170 gasoline engine starts, it starts again after a while, and then it can't be started, what is the reason, hello dear, the reason why the 170 gasoline engine starts and turns off is that carbon deposition will cause insufficient gasoline combustion and the gearbox is loaded. 1. Carbon deposition will cause insufficient gasoline combustion: the engine will shake.

Carbon deposits in the engine have a significant impact on the car. The first is to reduce the engine power, that is, to make the power output uneven and gradually decay, in other words, more and more powerless. The second is to increase fuel consumption and increase your financial burden.

The third is the difficulty of starting the cold dress, that is, the difficulty of ignition, it is not easy to get on the car, and finally the carbon deposition in the combustion chamber will also cause cylinder detonation, and the low speed acceleration will make a sound, causing damage to the piston and crankshaft, causing high engine temperature and seriously affecting the safety of the car. Hope it helps. If my answer is helpful to you, please give a thumbs up (in the lower left corner), look forward to your missing likes, your efforts are very important to me, and your support is also the driving force for my progress.

I wish you good health and a happy mood again!
