The effects of excessive engine oil in a car include: 1. Affecting power output; 2. Exceeding emission standards, impacting the environment; 3. Feeling lack of power while driving, damaging the catalytic converter; 4. Increasing noise, raising pressure in the crankcase, and elevating engine temperature; 5. Generating excessive oil vapor, leading to carbon buildup in the throttle, valves, and engine. The functions of engine oil are: 1. Reducing friction and high temperatures; 2. Cooling and lowering temperature; 3. Cleaning and purifying; 4. Damping and cushioning; 5. Preventing rust and corrosion. The method for changing engine oil is: 1. Lift the vehicle with a jack, locate and loosen the drain plug to drain the oil; 2. Remove the oil filter and place a container beneath it; 3. Replace with a new oil filter and add new oil.

What is the normal tire pressure range for the Envision 20T?

The normal tire pressure range for the Envision 20T is 2.4-2.5 bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2 bar in winter and reduced by 0.1 bar in summer. This data is based on the international GBT2978-2008 standard requirements. The Envision 20T is equipped with a direct tire pressure monitoring system (TPMS), which displays real-time tire pressure values on the dashboard. The TPMS technology automatically monitors various tire conditions in real-time by recording tire rotation speeds or through electronic sensors installed in the tires, providing effective safety assurance during driving. Generally, a tire pressure exceeding 2.8 bar is considered too high, while a pressure below 2.0 bar is too low. Hazards of overinflated tires: Reduced tire friction and adhesion, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates wear on the central tread pattern, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overstretches tire cords, reducing elasticity and increasing the load on the vehicle during driving. Hazards of underinflated tires: Increases friction coefficient with the road surface, leading to higher fuel consumption; makes the steering wheel heavy and prone to deviation, compromising driving safety; increases movement in various parts of the tire, causing abnormal heat due to excessive rolling; degrades the function of cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, causing damage to the bead area and abnormal wear; multiplies friction between the tire and the ground, sharply raising tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in a tire blowout. If the tire pressure monitoring indicator light illuminates (a yellow symbol featuring an irregular circle without a seal, with four small spikes at the bottom and an exclamation mark inside), it is generally due to one of the following three reasons: Abnormal tire pressure: Typically, the system alerts when pressure is below 1.8 bar or above 3.0 bar. In this case, tire inspection and pressure adjustment are necessary. TPMS not reset: After inflating the tires, if the TPMS is not reset in time, the system continues to record the previous data, causing the indicator light to illuminate. Simply performing a TPMS reset will resolve this issue. Damaged tire pressure sensor: The sensor, which monitors tire pressure, is directly installed inside the tire and connected to the inflation valve. If the sensor is damaged during driving (e.g., by hitting a curb), the tire pressure warning light will activate. Damaged sensors must be replaced with new components.

What causes small rust spots on cars?

That is because the paint on the car's surface has aged, allowing water to penetrate through the paint and oxidize with the metal, causing rust. Repainting or polishing followed by regular waxing can resolve the issue. Below is an introduction to related content: 1. Smooth and glossy paint surface: Polishing utilizes physical cutting methods combined with abrasive compounds as a medium to remove unevenness on the paint surface, achieving a smooth and glossy finish. 2. Polishing: Polishing is a process that removes surface irregularities from the paint. By eliminating some of the paint layer to create a more even surface, it increases the reflection angle of the paint, making it appear brighter and shinier.

Why does the shaking at 40 exceed the non-shaking condition?

40 shaking exceeding non-shaking is caused by carbon deposits in the engine throttle intake pipe combustion chamber, ignition system failure, and other reasons. Here are the specific details: 1. Causes: Carbon deposits in the engine throttle intake pipe combustion chamber, forgetting to release the handbrake, insufficient engine oil, poor quality of engine oil, excessive spark plug gap, insufficient tire pressure leading to imbalance, aging engine components. 2. Solutions: Severe engine carbon deposits, clean the fuel system, check and clean the idle motor for carbon deposits if necessary. Ignition system failure, check if the spark plugs have excessive carbon deposits, replace the spark plugs. Unstable oil pressure, check the oil pressure, replace components if necessary. Aging engine components, replace the components.

What Temperature Setting for Car AC Saves Fuel?

The car's summer air conditioning should be set around 21 to 25 degrees Celsius, while the winter setting should be around 25 to 28 degrees Celsius. Below is relevant information about saving fuel with air conditioning usage: 1. Car Air Conditioning: The car air conditioning system is a device that cools, heats, ventilates, and purifies the air inside the cabin. It provides a comfortable environment for passengers, reduces driver fatigue, and enhances driving safety. 2. Causes of Odors in Car Air Conditioning: When the air conditioning system operates, moisture in the air condenses on the evaporator surface, creating a damp and dark environment that becomes a breeding ground for mold, fungi, and dust mites. Additionally, nicotine from smoking inside the car can contribute to odors.

What parts are usually maintained during the first car service?

According to the vehicle's usage, the first service typically involves replacing engine oil, transmission fluid, lubricants, wiper blades, antifreeze, etc. Below are detailed explanations about the first car service: 1. Overview: As the first comprehensive check-up after the vehicle hits the road, timely problem detection ensures subsequent driving safety. Most dealers offer free first vehicle maintenance services, so the first service at a 4S shop is usually free of charge. 2. Notes: Owners need to bring their vehicle license, maintenance manual or warranty manual. It's recommended to call the nearest 4S shop in advance to schedule the first service appointment to avoid long waiting times due to high customer volume on the service day.
