What is the problem with car idling vibration?

The causes of car idling vibration include the vehicle being equipped with a three-cylinder engine, clogged fuel injectors, excessive engine carbon deposits, or a dirty fuel filter. Here is the relevant information: 1. Usually, car idling vibration and instability are manifested in the idling condition, where the tachometer needle fluctuates up and down and is very unstable. Generally, the idling speed has a certain range, around 1000rpm to 1500rpm. If the idling speed is too high or too low, it will lead to increased fuel consumption, while idling vibration can easily cause the engine to stall automatically. 2. The fuel injector of an electronically fuel-injected car is a key component for fuel injection, and its service life is very long, reaching hundreds of thousands of kilometers. However, due to the colloid in gasoline, the fuel injection holes of the injector can become clogged, causing inconsistent fuel injection from each injector, resulting in inconsistent operation of each cylinder and causing engine vibration. The solution is to remove and clean them.

Where is the cabin air filter located in the Haval H7?

The cabin air filter in the Haval H7 is located at the footwell of the front passenger seat, on the inner side near the left foot position. The functions of the cabin air filter include: 1. Ensuring a tight seal with the housing to prevent unfiltered air from entering the cabin; 2. Separating solid impurities such as dust, pollen, and abrasive particles from the air; 3. Adsorbing moisture, soot, ozone, odors, carbon oxides, SO2, and CO2 from the air. The Haval H7 has dimensions of 4715mm in length, 1925mm in width, and 1718mm in height, with a wheelbase of 2850mm. The front track is 1645mm, and the rear track is 1596mm. It is equipped with an engine that delivers a maximum horsepower of 227Ps, a maximum power output of 167kW, and a maximum torque of 385Nm.

Is a Physical Examination Required to Get a Driver's License?

Getting a driver's license requires a physical examination, which mainly includes vision tests, height and color recognition ability, hearing, as well as examinations of the upper limbs, lower limbs, torso, and feet to check for any abnormalities. If someone has red-green color blindness, they cannot pass the standard driver's license physical examination; if their fingers are not fully functional, they can apply for a small car license but not a large vehicle license. The motor vehicle driving test is an examination to obtain a driver's license, using a nationally unified set of test subjects and passing standards. The test is divided into three subjects and four examinations: theoretical knowledge, field driving skills, road driving skills, and knowledge related to civilized driving. Different test items are specified according to different vehicle types. The basic process includes filling out forms, physical examination, application acceptance, fee payment, examination, and license issuance.

What type of engine oil is suitable for the Golf 6 1.4T?

The original engine oil is the recommended choice for the Golf 6 1.4T, with the oil specification being 5W-30. In terms of compatibility, the original oil is well-suited for the engine. However, depending on specific needs, other engine oils may offer additional benefits such as noise reduction, fuel efficiency, or enhanced performance. Therefore, you may also consider oils from brands like Mobil, Shell, or Castrol. The viscosity of engine oil varies with temperature, so it's important to pay attention to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means the oil can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, resulting in smoother cold starts for the car. The second number represents the oil's kinematic viscosity at 100°C. A higher number indicates better viscosity retention at high temperatures, which can be understood as improved lubrication performance under high-temperature conditions. The method for changing the engine oil in a Golf 6 1.4T is as follows: Wait for the engine temperature to cool down, allowing the oil to flow back into the oil pan. Use a wrench to loosen the oil drain plug and place an oil pan underneath to catch the old oil until it stops flowing. Start the engine and let it run for about 30 seconds to allow the oil in the main oil passages to drain out. Use a specialized wrench to remove the oil filter. Apply some new oil to the gasket of the new oil filter and hand-tighten it clockwise. Pour the new oil into the engine through the oil filler cap on the valve cover, typically filling up to three-quarters of the oil container. Start the engine and let it run for 5 minutes, checking for any leaks around the drain plug and oil filter. If leaks are found, perform necessary repairs. After stopping the engine, pull out the dipstick to ensure the oil level is within the standard range.

What are the steps for adding refrigerant from the low-pressure side?

The steps for adding refrigerant from the low-pressure side are: 1. Connect the manifold pressure gauge to the compressor and refrigerant canister, then use the low-pressure manual valve on the manifold pressure gauge to add gaseous refrigerant to the low-pressure side of the refrigeration system; 2. Open the refrigerant canister and loosen the nut on the middle injection hose connected to the manifold pressure gauge until you hear the sound of refrigerant vapor flowing, then tighten the nut to remove air from the injection hose; 3. Keep the refrigerant canister upright, fully open the low-pressure manual valve, and inject refrigerant from the low-pressure side. When the system pressure reaches 0.4MPa, close the low-pressure manual valve; 4. Start the engine, turn on the air conditioning switch, and set both the blower switch and temperature control switch to maximum; 5. Open the manual valve on the manifold pressure gauge to allow refrigerant to continue entering the refrigeration system until the filling amount reaches the specified value; 6. After filling is complete, close the low-pressure manual valve on the air conditioning pressure gauge, shut off the injection valve on the refrigerant canister, stop the engine, and remove the air conditioning pressure gauge.

Is it better to use 92 or 95 octane fuel for Golf 6?

According to the official vehicle manual recommendation, Golf 6 should use 95 octane fuel. In addition to checking the suitable fuel grade in the vehicle manual for Golf 6, you can also find it on the fuel tank cap, which will be clearly marked. Generally, the fuel grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92 octane fuel, while those with a compression ratio between 10.0-11.5 should use 95 octane fuel. However, with the application of some new technologies nowadays, the fuel grade cannot be solely determined by the compression ratio. A high compression ratio can also be adjusted to use lower octane fuel. This is because, besides the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally speaking, the higher the fuel grade, the higher the octane number and the better the anti-knock performance. 92 octane fuel contains 92% isooctane and 8% n-heptane, while 95 octane fuel contains 95% isooctane and 5% n-heptane. If Golf 6 occasionally uses the wrong fuel grade, simply switch back to the correct fuel grade after using it up. However, long-term use of the wrong fuel grade may have the following effects: For vehicles recommended to use lower octane fuel, using higher octane fuel by mistake will not cause damage. However, the increase in octane number will change the fuel's ignition point, leading to delayed combustion in the engine. This means both the engine's power output and thermal efficiency will decrease, resulting in poorer performance in actual driving experience. For vehicles recommended to use higher octane fuel, using lower octane fuel may cause engine knocking. Due to the significantly lower octane number, the fuel's ignition point decreases and may ignite prematurely during the compression stroke. If the fuel ignites before the spark plug fires during the compression stroke, resistance will occur during the upward stroke. This resistance will make the engine run very unstably. If it's mild knocking, it only increases noise without obvious damage to the engine. However, if there is noticeable knocking, it indicates severe engine conditions. The vibration not only affects driving stability but also causes abnormal wear on pistons and cylinders, and in severe cases, may lead to cylinder scoring.
