Kia k5 engine

The main reasons for engine jitter are as follows: First, in order to make the piston gain power immediately after compression top dead center and enter the power stroke, it is usually ignited in advance before the piston reaches top dead center, because it takes a period of time from ignition to complete combustion. However, premature ignition will make most of the oil and gas burn when the piston is still in the compression stroke, and the unburned oil and gas will spontaneously ignite under great pressure at this time, leading to engine jitter. Second, the engine has too much carbon deposit: too much carbon deposit in the combustion chamber will not only increase the compression ratio and produce high pressure, but also produce high-temperature hot spots on the surface of carbon deposit, which will make the engine shake. Third, the engine temperature is too high: if the engine is in a too hot environment, the intake air temperature will be too high, or the engine cooling water circulation will not be smooth, which will cause the engine to knock and shake at high temperature. 4. Incorrect air-fuel ratio: If the air-fuel ratio is too thin, the combustion temperature will increase, which will increase the engine temperature and make it easy to shake. V. The octane number of fuel is too low: Octane number is an indicator of the anti-knock performance of fuel. The higher the octane number, the stronger the antiknock performance. The engine with high compression ratio has high combustion chamber pressure, and it is easy to knock if the fuel with low antiknock property is used.

What is the reason for the lack of power of KIA k5?

Reasons for insufficient automobile power:

1. Reasons for fuel supply system:

Because the vent hole of the fuel tank cover is blocked, the fuel tank switch, fuel filter and fuel tank are all connected to the carburetor.

The oil pipe between pipes is partially blocked, which can not meet the required oil supply, resulting in too thin mixture and weak engine work.

2, the cause of the ignition system:

Inappropriate ignition timing and premature ignition lead to premature combustion and detonation of combustible mixture. Due to the ignition system

Spark plug failure leads to spark plug fracture or weak spark plug.

3. Compression pressure of cylinder:

The serious wear of piston, piston ring and cylinder leads to the increase of fit clearance between piston, piston ring and cylinder.

Coupled with the poor sealing performance, the cylinder head leaks air and reduces the compression pressure of the cylinder.

4, engine overheating:

Incomplete combustion of combustible mixture due to various reasons leads to excessive carbon deposition in the combustion chamber.

It leads to poor heat dissipation and overheating due to the increase of engine load.

5, lubricating oil problem:

Too much or too little lubricating oil in the crankcase will deteriorate or become dirty, blocking the lubricating oil passage and affecting the power of the engine.

Daily maintenance of automobile use:

First, the maintenance of automobile engines

Car engines should be cleaned at the right time. Because long-term use will form a thick layer of carbon deposit on the engine surface, which will have a great corrosive effect on the rubber parts in the engine.

Second, we should prevent gasoline and water from evaporating.

In summer, the temperature is generally higher. So gasoline and water evaporate more easily than usual. Because the water tank and oil tank should be checked frequently, gasoline and water should be added in time when there is little.

Third, pay attention to hygiene in the car.

Summer is the fastest season for bacteria to multiply, so it is necessary to keep the car clean, especially the car seat cushion, steering wheel cover and car mat.

Fourth, the car wiper should be replaced.

When driving in rainy days, be sure to pay attention to the wiper. The rubber sheet on the wiper will age for a long time. In order to have a better driving sight when driving in rainy days, it is best to replace the wiper once every two years.

Fifth, the car mats should be updated.

Good automobile cooling pad is an important choice for automobile sun protection in hot season. Choose a cool mat that is not too slippery. In order to avoid slipping while driving and causing traffic accidents.

Sixth, the body should also be maintained.

Ultraviolet rays are also very harmful to cars, such as the penetration of car paint. You may notice that after a white car has been exposed to the sun for a long time, the color of the car body will obviously turn pale and yellow. Therefore, waxing and polishing your car in summer can protect your car.

Common faults of KIA k5 engine

1, automobile cooling system or exhaust system failure, resulting in engine overheating and abnormal noise.

2. The engine block or throttle has serious carbon deposition.

3. Relationship between abnormal sound and engine duty cycle. The abnormal sound fault of the engine is often obviously related to the duty cycle of the engine, especially the abnormal sound of the crank-connecting rod mechanism and the valve train is related to the duty cycle.

Kia k5 engine

KIA k5 engine is a joint-venture domestic KIA K5, which is a mid-to-high-class car owned by KIA of Dongfeng Da Yue. The design with high waistline and strong tension makes K5 more dynamic, reflecting a kind of vigor and vitality. This heavyweight model was officially launched in Kerry Hotel, Pudong, Shanghai on March 20th110. The appearance of this car has changed a lot, making it more fashionable and avant-garde. Overall style sports, quite competitive.

Dongfeng Da Yue Kia K5 is a brand-new mid-to-high-class car, full of sports sense. It was designed by Peter Schreyer, one of the three largest automobile designers in the world. Its initials "K" are taken from the English initials "KIA" and "Kinetic", representing Kia's leading car-making concept and cutting-edge technology.

How to deal with KIA k5 engine cylinder knocking?

KIA K-5 engine knocking is normal. Knocking is due to the wear of the cylinder block and piston, and the gap between them becomes larger. Especially when the piston skirt is worn, the knocking sound will be obvious. In general, the sound will increase when the engine is cold or under heavy load. Knocking on the cylinder is because the gap between the piston and the cylinder block becomes larger, so the compression situation will become worse, the engine power will decrease, the wear will increase, and the noise will increase, and other aspects have basically no obvious influence.

Engine failure

First of all, we must determine whether it is knocking on the cylinder. The identification steps and methods are as follows: the abnormal sound is obvious at idle speed, but it is weakened after refueling, indicating that it is the abnormal sound of the valve or generator water pump. Abnormal noise is weak at idle speed, and the more refueling, the greater the abnormal noise, which may be knocking on the cylinder. Moreover, when idling, the rear exhaust pipe makes a knocking sound, that is, knocking on the cylinder. If the sound of knocking on the cylinder is loud, the engine must be disassembled for repair. If it is not knocking on the cylinder, the abnormal sound can be eliminated after debugging the valve or replacing the accessories.

When the piston knocks on the cylinder, the following methods can be adopted:

After the engine is started, there is knocking sound when running at low temperature. When the temperature is normal, the sound disappears, so you can continue running without treatment.

When the engine temperature is normal, there is obvious knocking sound, so try to avoid high-speed operation and disassemble and repair it as soon as possible.

After removing the cylinder head and pulling out the piston, it is found that the cylinder is seriously out of round and strained, or the gap between the piston and the cylinder is too large, so it should be replaced, and the cylinder liner, piston and piston ring should be replaced.

If the connecting rod is found deformed, it should be replaced as much as possible.

What is the quality of KIA K5 engine? Does it have many small problems?

Advantages: appearance

Disadvantages: the only dissatisfaction is that the start is a bit meaty and the speed is still very good.

Appearance: Appearance is the biggest highlight of K5. Although it has been listed for many years, it never looks back.

Interior: All-black interior not mentioned.

Space: There is not much space to talk about, especially the back row is spacious.

Configuration: Super cost-effective. For example, it is to spend Anta's money to buy an Adi's shoe. Except Anta, Adi is not famous.

Motivation: Motivation can be said. First, it is not turbocharged, and second, the displacement is not large. How fast can it be? Let's wait for someone to drive. I feel that I am not as fast and impatient as the other K5 on the street. I don't care about oil. Getting started is really better than others. First, the accelerator rushed out, and then the second gear, repeatedly five or six thousand. Then I stepped on the gas pedal. Generally speaking, I will. It's harder to compete with turbocharging. After all, it depends on who dares to drive. Once when I was speeding up, I met a Cayenne, which climbed side by side with him to 160. He stepped on the brake, but I didn't. Don't compare with others when speeding up. Their prices are there.

Control: the gear of the model is clear and the shift is smooth; The chassis is stable and comfortable to hang; The steering wheel is moderate and the steering is clear.

Fuel consumption: 8.5 fuel consumption is acceptable.

Comfort: The front and rear seats are very comfortable and well wrapped.

Advantages: the appearance is very coquettish and the wheels are very powerful. I saw Hyundai Lang Lang K3 before buying a car. Later, I heard a friend talk about this decisive decision. I thought about Meng Xin, too. Because I just started a business, I will take a year to switch to what I want to open. After driving for more than a month, I feel that the seat is still barely acceptable. After all, it is not a good car. Domestic use is enough.

Disadvantages: The most unsatisfactory thing is that the tire noise is too loud, the sound insulation effect of the whole vehicle is not ideal, and the noise of starting the generator exceeds expectations, which is also the loudest one among many family cars I have driven. I don't know what the problem is. I also asked about 4S, but the official replied that it was normal! I am very helpless! ! !

Appearance: Needless to say, everyone knows this.

Interior: I have to say that the fit of the interior needs to be improved. The texture of the seat cover and steering wheel cover is good.

Space: When the three adults in the back row were sitting under the least pressure, five trunks were made in the back, and it was no problem to put three or four trunks.

Configuration: high

Power: Because there is no T, the feeling of pushing back is definitely weak, but it is not a racing car, and it is relatively stable at the beginning of refueling.

Manipulation: I can always open my left leg manually before, so I'm in a hurry.

Fuel consumption: I travel from the village to the county seat 19 km. There are 7 traffic lights on the road, and the fuel consumption is about 10, which is within my tolerance. I feel much better than American cars in fuel consumption! ! I haven't run a long-distance race yet. I heard that long-distance running is very fuel-efficient.

Comfort: driving comfort.
