What is the solution for oil accumulation in the throttle of the new Mondeo?

To address oil accumulation in the throttle of the new Mondeo, it is necessary to replace the throttle. Below is relevant information about the throttle: 1. Working Principle: The throttle is a controllable valve that regulates the entry of air into the engine. Once the air enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then ignites to perform work. 2. Location: The throttle is connected to the air filter at the top and the engine block at the bottom, often referred to as the throat of the car engine. 3. Maintenance: The throttle requires periodic replacement, with the interval primarily determined by factors such as the quality of the air filter, the quality of the engine oil, and the driving conditions of the vehicle. 4. Types: There are four types of electronic throttles: electro-hydraulic, linear solenoid, stepper motor, and DC servo motor.

What to Do When Headlights Have Water or Fog Inside?

Headlights having water or fog inside is due to condensation or water ingress in the car lights. Below are related details about headlights with water or fog: 1. Condensation in car lights: The main reason for fogging inside the lights is usually high air humidity, causing water vapor in the air to condense inside the light. Turn on the lights and wait for a while, and the fog will naturally dissipate. This kind of fogging is a normal phenomenon, related only to air humidity. Generally, the amount of condensed water vapor is minimal, and after keeping the headlights on for about 15 minutes, the moisture will evaporate without leaving any residue inside the lights. 2. Water ingress in car lights: Heavy rain, car washing, or snow can cause a significant amount of water to enter the headlights, indicating a serious sealing failure. In such cases, the headlights must be replaced or resealed. Typically, water enters from the top of the light and flows to the bottom, leaving noticeable water flow marks similar to a waterfall. Even after drying, some traces may remain. It is crucial to replace the lights promptly to prevent accidents. 3. Preventive measures: During winter and rainy seasons, it is advisable to develop a habit of regularly checking the headlights, especially after driving through water. Early detection and timely repairs can eliminate potential issues at the initial stage.

What is the correct way to use an exhaust brake?

The correct way to use an exhaust brake is as follows: 1. Automatic shutdown: When the vehicle is in motion and the driver presses the accelerator pedal or clutch pedal, the exhaust brake will automatically shut off. 2. Avoid usage: It is best not to use the exhaust brake when driving in rainy weather or on slippery roads, as it may cause the vehicle to skid or even overturn. Precautions for using the exhaust brake are as follows: 1. The exhaust brake is an auxiliary brake and cannot replace the service brake for emergency braking, nor can it be used for parking braking. However, the exhaust brake can be used simultaneously with the service brake. 2. When using the exhaust brake, the accelerator pedal should be at zero position, and the fuel injector stops injecting fuel. If the accelerator pedal or clutch pedal is pressed, the exhaust brake will automatically shut off, preventing the engine from stalling when stopping and ensuring the exhaust brake operates during fuel injection. 3. It is advisable not to use the exhaust brake on icy or slippery roads, as there is a risk of the vehicle's drive wheels skidding or sliding. 4. The braking power of the engine exhaust brake depends on the engine speed (the higher the engine speed, the better the braking effect). To ensure optimal braking performance when using the exhaust brake on long downhill slopes, select an appropriate gear (the transmission should not be in neutral) to keep the engine speed between 1600-2400 rpm.

Do I Need to Replace a Tire with a Nail Puncture?

Tire punctured by a nail: If the nail punctures the sidewall, replacement is necessary; if it punctures the tread, only repair is needed, not replacement. Whether to replace the tire depends on the location and extent of the damage. If the nail punctures the tread and isn't too thick, it can be repaired at a professional repair shop. Conditions requiring tire replacement include: puncture hole diameter in the tread exceeding 6mm; sidewall puncture; deformation of the bead or tread; corrosion of the tire; damage caused by driving underinflated. Tire repair methods include: plugging, sealant injection, cold patch, hot patch, and mushroom plug. Plugging is the most common method, involving inserting a special rubber strip into the puncture. This method is quick and convenient, taking only minutes, and doesn't require removing the tire from the rim. Tire sealant is a white foam-like liquid, a synthetic polymer compound stored in a compressed canister. When used, it's injected through the valve stem, simultaneously sealing and inflating the tire. Under the centrifugal force of driving, the sealant evenly coats the inner tire surface, forming a sealing film that repairs the puncture. Cold patching requires removing the tire from the rim, locating the puncture, cleaning the area, and applying a special patch from the inside. Hot patching is similar but includes an additional step of heating the patch with a curing machine until it melts and bonds with the puncture. The mushroom plug uses a mushroom-shaped rubber patch inserted from inside the tire, with the stem pulled through the puncture, trimmed on the outside, and secured with adhesive on the inside.
