How Many Cylinders Does the New Focus Engine Have?

The new Focus uses a three-cylinder engine, equipped with a 1.5L naturally aspirated engine. The new Focus model is GTDIQ75, with a maximum horsepower of 122ps, a maximum power of 90kw, and a maximum torque of 153nm. Here are some daily maintenance methods for the new Focus engine: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected according to mechanical load, with the selection standard not lower than the manufacturer's requirements; Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, causing various problems for the engine. To avoid failures, change the oil regularly based on usage conditions and keep the oil level moderate; When oil passes through the fine holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is blocked and oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing oil to bypass through the bypass valve, bringing dirt back to the lubrication area, accelerating engine wear and increasing internal pollution; Regularly clean the crankcase. During engine operation, high-pressure unburned gas, acid, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from part wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, blocking filters and oil holes, making engine lubrication difficult and causing wear; Regularly use radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.

What is the difference between Castrol Edge and Castrol Magnatec?

Magnatec is a semi-synthetic oil, while Edge is a fully synthetic oil. The specific differences between the two are as follows: 1. From the perspective of base oil, Magnatec's base oil is made from Group III hydroprocessed oil, while Edge 0w series base oil is 100% Group IV, and the 5w series base oil is a blend of Group IV and Group III hydrocracked oil. 2. From the engine perspective, Edge provides comprehensive engine protection, with API/viscosity grades of SN/0W-40, SN/5W-40, SN/5W-30, and SN/10W-60. Below is additional information: 1. How to choose engine oil. When selecting engine oil, the primary consideration should be its viscosity index. Speed, engine load level, and temperature are the three main factors in choosing viscosity. The higher the speed, the lower the viscosity oil you should choose; the higher the load, the higher the viscosity oil you should choose; and the higher the temperature, the higher the viscosity oil you should choose. 2. How to identify engine oil quality. The quality of engine oil depends on: base oil and additives. The quality of the base oil depends on: crude oil source and refining technology, as well as synthetic process technology.

Does Not Disconnecting the Wires Affect Car Charging?

Not disconnecting the wires during car charging does not have any negative effects. In fact, disconnecting them can lead to the loss of some data in the ECU. After the charging connection is broken, restarting the car may result in increased fuel consumption because certain data stored in the ECU will be lost. The car's ECU has a strong learning capability—it can learn the driver's habits and save this data. If the battery's positive and negative terminals are disconnected, the ECU loses the data related to the driver's habits, leading to noticeably higher fuel consumption when driving again. This is why many drivers experience increased fuel consumption after replacing the battery, as some ECU data is lost. It is best to charge the car battery without disconnecting it. Simply connect the positive terminal of the charger to the battery's positive terminal and the negative terminal of the charger to the battery's negative terminal. Precautions for car battery charging: In cold weather, check if the electrolyte is frozen before charging—never charge a frozen battery as it may cause an explosion. Also, check the electrolyte level before charging; do not charge if the electrolyte is insufficient. During charging, measure the electrolyte density and voltage every hour and monitor the temperature.

Should the Clutch Be Pressed When Braking in Subject Three?

Subject Three braking requires pressing the clutch. The requirements for vehicle speed are relatively high, and it generally involves high-speed driving. The higher the speed, the greater the inertia. If the clutch is pressed first, the vehicle's inertia will be even greater, potentially leading to the dangerous situation of coasting in neutral. Therefore, when decelerating at high speeds, you should first press the brake to reduce the speed to a certain level, then press the clutch to perform a downshift operation and slow down further. The road driving skills test for Subject Three generally includes: 1. Preparation before starting, simulated lighting test, starting, driving in a straight line, shifting gears up and down, changing lanes, pulling over to the side, passing through intersections straight, turning left at intersections, turning right at intersections, passing through pedestrian crossings, passing through school zones, passing through bus stops, meeting vehicles, overtaking, making U-turns, and nighttime driving. 2. Starting from June 1, 2021, the interval for scheduling the Subject Three test was adjusted from 30 days after passing the Subject One test to 20 days. For those applying for additional licenses for large and medium-sized passenger and truck driving, the interval for scheduling the Subject Three test was adjusted from 40 days after passing the Subject One test to 30 days.

Is Running a Yellow Light Considered Running a Red Light?

Running a yellow light and running a red light are both categorized under the same traffic violation—driving a motor vehicle in violation of traffic signal regulations. According to Article 90 of the 'Road Traffic Safety Law of the People's Republic of China,' a fine of 200 RMB and 6 penalty points will be imposed. The yellow light at an intersection serves as a warning. Motor vehicles should slow down when approaching the intersection. If a vehicle has already crossed the stop line when the yellow light turns on, it may continue to pass through. However, if the vehicle has not yet crossed the stop line, it should come to a stop. Article 38 of the 'Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China' states the following for motor vehicle and non-motor vehicle traffic signals: When the green light is on, vehicles are permitted to proceed, but turning vehicles must not obstruct the passage of through vehicles or pedestrians. When the yellow light is on, vehicles that have already crossed the stop line may continue to pass through. When the red light is on, vehicles are prohibited from proceeding. At intersections without non-motor vehicle or pedestrian crossing signals, non-motor vehicles and pedestrians should follow the motor vehicle traffic signals. When the red light is on, right-turning vehicles may proceed if they do not obstruct the passage of through vehicles or pedestrians. Electronic surveillance captures red-light violations based on the following three photos, which are reviewed by traffic police to determine whether a red light was run: An image of the vehicle not having passed the stop line when the red light turns on. An image of the vehicle's front wheels crossing the stop line. An image of the vehicle's entire body having crossed the stop line. If these three photos show that the vehicle moved beyond the stop line while the red light was on, the traffic police can confirm it as a red-light violation during review. To avoid running a yellow light: slow down when approaching an intersection, maintain a speed of 20–30 km/h, keep a safe distance from the vehicle ahead to prevent rear-end collisions or rushing through a yellow light. Alternatively, pay attention to the traffic signals in advance—observe the duration of the green light when it is on. If traffic is light and the green light duration is long, prepare to slow down.

Can I file for a color change without the vehicle registration certificate?

It is not possible to file for a color change registration without the vehicle registration certificate. According to Article 90 of the "Road Traffic Safety Law," the following documents are required for submission: the "Application Form for Vehicle Modification Registration," original and photocopies of the identity proofs of the vehicle owner and agent, the original vehicle registration certificate, the original vehicle license, and payment of all fines before the color change. According to Article 6, Chapter 2 of the "Road Traffic Safety Law," if the color change area of a vehicle does not exceed 30%, there is no need to apply for modification registration. Conversely, if it exceeds 30%, the change must be filed and registered within 10 days after the vehicle's color is changed. Precautions for vehicle color changes: Before changing the color of a vehicle, it is necessary to consult the local vehicle management office where the vehicle is registered to check whether the region allows the use of wraps to change the vehicle color. If the region does not support this method, the filing procedure cannot be processed after the color change, and the wrap must be completely removed to restore the vehicle's original color. Additionally, according to the "Vehicle Registration Regulations," owners are no longer required to apply to the vehicle management office in advance. They can first change the vehicle color, install body kits, replace the engine, etc., and then apply to the vehicle management office for modification registration. According to Article 10, registered vehicles must apply for modification registration under the following circumstances: Change of body color. Replacement of the engine. Replacement of the body or frame. Replacement of the entire vehicle due to quality issues. Change of use, such as converting a commercial vehicle to a non-commercial vehicle or vice versa. The vehicle owner's residence moves into or out of the jurisdiction of the vehicle management office. Furthermore, according to Article 15 of the "Road Traffic Safety Law of the People's Republic of China": Police cars, fire trucks, ambulances, and engineering rescue vehicles must be painted with specified patterns and equipped with alarms and signal lights as required. Other vehicles are not allowed to paint, install, or use patterns, alarms, or signal lights that are exclusive to or similar to those of the aforementioned vehicles.
