Car doubts! Expert answers! Car Problems?!?

Japan Honda has cooperated with Dongfeng and Guangzhou Automobile Company, they produce different models of Honda cars, more than two Honda companies, just like GAC Toyota and FAW Toyota, displacement is the volume of the engine working piston from the top dead center to the bottom dead center, that is, the displacement is literal, and the displacement is large and the power is good

Displacement, a hydraulic transmission term, refers to the volume of fluid drawn or discharged per stroke or cycle. Usually the displacement is large, and the energy released by the engine per unit time (that is, the chemical energy of the fuel is converted into mechanical energy) is large, that is, the "power" is good, just like a teenager boy is of course more efficient than a healthy adult. So those off-road vehicles and sports cars usually have a relatively large displacement.

Dongfeng Honda is produced in Wuhan, Guangzhou Honda is produced in Guangzhou, strictly speaking, Dongfeng Honda is more pure than Guangzhou Honda. There are four models of Hiromoto's cars, Accord, Odyssey, Fit, Fengfan, and Tomoto have two, CRV and Civic, regardless of the level.

The working hours of each store are not the same, this Guangben and Dongben Group do not care, the working hours of the stores are set by themselves, because these 4S stores are not directly led by the group, to put it bluntly, who has money will join the nature, but the orders of the headquarters need to be obeyed, and the rebates and rewards given by the group at the end of the year. The real bosses of the store employees are actually the owners of private companies. It is said that the working hours are 8 hours, but if you do something salesman, then it is impossible to leave work on time, and the sales tasks of each month are set outside your ability, so that the company needs to give achievements can be reduced because you can't complete the task.

The pressure of customer service is not small, in addition to a variety of car friend activities, there is a daily return visit task, very mechanical to buy a car users to call a return visit, advice, there is a customer complaint to solve, if there is no timely tracking information, Guangben·· If the quarterly CSI SSI score comes out because the customer is tracking this aspect, it will also be severely punished, because it will be related to whether you can get rebates at the end of the year. But no matter in which department, as long as this kind of 4S shop will not have a normal day off, it is someone else who goes to work and you rest, others rest and you go to work, 8 days a month to rest is basically hopeless, sometimes there is something to do with the shift rest and say that you have to go back to work, maybe you are hanging in the name of rest, and you have to spend a day in the unit, the only thing that is different from the person who goes to work may be that you don't have to go to the roll call early, half an hour later than others to the unit, and half an hour earlier than others after work, but there is no dime.

1. Body: It is the assembly base of each part of the engine. It includes the cylinder head, cylinder block, lower crankcase (oil pan). The cylinder head and the inner wall of the cylinder block together form part of the combustion chamber. Many parts of the body are part of other systems.

2. Crank connecting rod mechanism: It is a mechanism used by the engine to generate and transmit power, through which the linear reciprocating motion of the piston is transformed into the rotary motion of the crankshaft and output power. It includes pistons, piston pins, connecting rods, crankshafts with beam slag and flywheels, and cylinder blocks.

4. Fuel supply system: The fuel supply system of gasoline engine includes gasoline tank, gasoline pump, gasoline filter, air filter, carburetor, intake pipe, exhaust pipe, exhaust muffler, etc. Its function is to mix gasoline and air into a suitable combustible mixture and supply it to the cylinder for combustion, and exhaust the exhaust gas generated by combustion to the engine.

5. Cooling system: mainly including water pump, radiator, phoenix fan, water distribution pipe, cylinder block and water jacket in the cylinder head. Its function is to dissipate the heat of high-heat parts into the atmosphere to ensure that the engine is working normally.

6. Lubrication system: including oil pump, pressure limiting valve, lubricating oil channel, filter collector, oil filter and oil radiator, etc. Its function is to supply lubricating oil to the friction parts to reduce the friction resistance between them, reduce the wear of the parts, and partially cool the friction parts and clean the friction surface.

7. Starting system: including the starting mechanism of the engine and its auxiliary devices.

<><Automobile maintenance knowledge, these few faults to understand!

Maintenance has always been a headache for car enthusiasts. They are not professional enough and don't want to spend money. Today, I would like to introduce you to some common maintenance knowledge, so that when you see these "symptoms", you can know what is wrong with your car.

Black smoke coming out of the exhaust pipe.

Fault Judgment: True Fault.

Cause analysis: This indicates that the mixture is too dense and the combustion is incomplete. The main reasons are car engine overload, insufficient cylinder pressure, low engine temperature, improper carburetor adjustment, clogged air filter, individual cylinders not working, late ignition, etc.

When excluding, check whether the choke is fully open in time, and maintain it if necessary. After the ignition is turned off, look at the main nozzle from the carburetor port. If the oil is injected or dripping, the oil level in the float chamber is too high.

Adjust to the specified range, tighten or replace the main metering hole. The air filter is clogged and should be cleaned, unclogged or replaced.

Blue smoke coming out of the car's exhaust pipe.

This is because a large amount of oil enters the cylinder and cannot be burned completely. If you remove the spark plugs, you will find that the Paino wheel has serious carbon deposits. It is necessary to check whether the oil level is too high; whether the gap between the cylinder and the piston is too large; whether the piston rings are installed backwards; whether the intake valve guide is worn or the seal is damaged; whether the cylinder head gasket is ablated, etc.

If necessary, repairs should be made.

White smoke from the exhaust pipe (sometimes when the car is cold, but not after the car is hot).

Fault Judgment: False Fault.

This is because gasoline has water in it and the engine is too cold. At this point, incomplete combustion of fuel entering the cylinder can lead to fog spots or white smoke formation from spine water vapor. In winter or during the rainy season, white smoke can often be seen when the car is first started.

It doesn't matter, the white smoke will disappear as soon as the engine temperature rises. This situation does not require maintenance.

The engine is too noisy.

Fault Judgment: Use the category of fault.

When lifting the vehicle, you can see bump marks on the underside guard of the engine. If the road is blocked and forced through, the underside engine guard will be impacted. After deformation, the distance between the bottom guard and the engine oil pan becomes closer.

If the distance is too close, the oil pan collides with the bottom guard plate when accelerating, which will produce abnormal noise and the body will vibrate. Therefore, it is necessary to carefully observe the road surface when driving to avoid causing the phenomenon of dragging the bottom. Solution:

Remove the bottom guard, flatten and correct.

The steering wheel of the vehicle is always not right.

This is because the rubber stops fixed in the grooves of the steering machine have been completely damaged. After the installation of the new limit block, the fault disappeared completely.

Common car faults and solutions.

First, the engine can not start. Causes: a. The engine has been flushed, causing water to enter the distributor, ignition module, spark plug, high-voltage line, etc.

b. The spark plug is damaged. c. The battery voltage is insufficient. d. The inertia switch is disconnected.

Preventive and solution measures: a. Avoid direct flushing of the engine. b. Regularly inspect, adjust or replace the spark plugs.

c. Designated service station to inspect and replace damaged parts. d. Charge the battery. e. Press the inertia switch to restore the circuit.

2. The engine is turned off when changing gears. Causes: a. The idle speed is too low.

b. The idle shut-off valve is not tightened. c. The gear is too high. d. The oil-gas separator is seriously blocked.

Preventive and solution measures: a. Adjust the idle speed to normal speed. b. Check whether the idle stop valve is tightened and whether the plug is tightened.

c. Shift into a lower gear. d. Clean the oil-gas separator at the designated service station. 3. The steering wheel trembles at high speeds.

Causes: a. The tire is not dynamically balanced after disassembly. b. The balance weight on the wheel falls off.

c. The wheels are stained with mud. d. The wheel is deformed by impact. Preventive measures:

a. Carry out tire dynamic balance testing. b. Pay attention to cleaning the wheels. c. Replace the wheels.

Fourth, the turn is heavy. Causes: a. Insufficient tire pressure.

b. The power steering fluid is not enough. Preventive measures: a. Inflate the tires.

b. Add power steering fluid. Fifth, deviation when driving. Reason:

a. The air pressure of the left and right tires is inconsistent. b. The front wheel alignment is not accurate. c. A certain brake is locked.

Preventive measures: a. Check and adjust the tire pressure. b. Go to the designated service station for maintenance.

1. About the difference between manual transmission and automatic transmission.

Manual transmission is to use people to operate the gearbox and change the gear.

The automatic transmission is controlled by the computer, and the gear change is automatically controlled according to the state of the vehicle and the driver's habits;

Manual automatic transmission is a kind of automatic transmission, which is usually an automatic transmission, but if necessary, it can be switched to manual mode, allowing the driver to control the change of gear by himself, but it is still automatic in nature.

2. Is it better to have a manual transmission or an automatic transmission or a manual automatic transmission?

It all depends on your individual needs.

Manual transmission: the smallest power loss (relatively fuel-efficient), simple structure, cheap, can meet some people's inexplicable feelings for manual transmission. The biggest disadvantage is that it is relatively troublesome, you need to cooperate with the clutch, and the driving will be more classy, and for novices, you may also encounter the problems of stalling and starting half-slope.

Automatic transmission: mainly including AT, CVT, dual-clutch these types, in general the biggest advantage is that it is more trouble-free, especially with the electronic handbrake or something, even if the city traffic jam is not too tired, and for novice drivers are more friendly, there is almost no problem of stalling, there is almost no requirement for shift technology, is the current mainstream. The disadvantage is that there is more or less power loss (the dual-clutch may be smaller), the structure is complex, the cost and maintenance are more expensive than the manual one, and it is difficult to withstand the power output of large torque (mainly the CVT type automatic transmission, but this is not a problem for customers, and the technology is constantly improving);

3. Is the manual transmission more powerful?

It can only be said that under the same circumstances, the power loss of the manual transmission is minimal, and with the driver's technology, it is often easier to squeeze stronger power than the automatic transmission. This is also the reason why many performance cars and racing cars retain manual transmissions;

4. Is automatic transmission better in more crowded and complex cities?

Must, every time you start with a manual transmission, you have to clutch, shift, fuel or something, and in a stop-and-go state, it's no wonder if you're not tired. Automatic transmission is different, if the car is equipped with an electronic parking brake, with the Auto Hold function, in the case of traffic jams, you only need to control the brake and accelerator, which saves a lot of trouble.

Got a few new ones, all the same.

As long as you put off the itch sensor, it is normal, what is the reason.

Answer: Then you have a damaged oxygen sensor. If the oxygen sensor adjustment is damaged, if you can't replace a few new ones, you must replace the original parts. This front oxygen sensor is the fuel regulation, the adjustment of the fuel pulse width, this must be replaced by the original friend, replace the original parts.

I told you, if my friend uses this oxygen sensor, it is this fuel adjustment pulse width sensor that adjusts the fuel pulse width, and if you want to replace it, you have to replace the original one.

The original lambda sensor must be replaced.

Question: Baojun 630 is out of production, you can only use the normal package, answer the normal package, this can't be helped, you can go to the 4S store to get an accessory and come back to install the 4S store. Go to the 4S store and buy back an accessory.
