Battery power supply system faults such as insufficient battery charge, failure of the main car power fuse, loose or oxidized battery terminals can easily lead to issues like the horn not sounding, dim instrument lights, slow window operation, dim car headlights, and flashing anti-theft indicator lights. Starter relay faults such as short circuits in the starter relay inductor coil, burnt or eroded moving or stationary contacts of the starter relay, excessive gap between the starter relay core and contact arm, etc. Starter motor faults such as issues with the starter DC motor, transmission mechanism faults, control device failures, starter switch faults, and failure of the car's start gear, etc.

Vehicle starting system failure refers to the situation where the car won't start and the engine fails to ignite. I've experienced this several times, most commonly due to a dead battery, especially during winter when low temperatures cause rapid power depletion and starting difficulties. Alternatively, it could be a faulty starter motor - when turning the key, you only hear clicking sounds without any action. Loose or corroded cable connections may also interrupt current transmission. Malfunctioning ignition switches and relay failures are equally common issues. These failures not only delay travel but may also cause breakdowns mid-journey, posing safety hazards. I now regularly check battery status, using a meter to measure voltage and ensure healthy values, performing starter system maintenance annually during oil changes. Battery lifespan is typically 4 to 5 years, so I replace it promptly when due to avoid unexpected failures.

What grade of gasoline does the Focus use?

The Focus uses 95-octane gasoline. The gasoline grade represents the anti-knock performance, with higher grades indicating better anti-knock capability. It has no relation to the quality of the gasoline itself, nor does it mean that higher-grade gasoline contains fewer impurities. Gasoline is classified into different grades such as 90, 93, 95, and 97 based on octane ratings. The dimensions of the Focus are 4647 mm in length, 1810 mm in width, and 1468 mm in height, with a wheelbase of 2705 mm. The Focus features front-wheel drive, a MacPherson strut front suspension, a torsion beam rear suspension, and a unibody structure.

What is the reason for the engine speed not dropping when releasing the throttle?

The reason for the engine speed not dropping when releasing the throttle is: the throttle spring has been in a compressed state for a long time, resulting in reduced tension, increased throttle opening, and increased fuel supply, causing the speed indicator to return slowly. It could also be due to faulty components or air leakage in the intake manifold. If the vehicle has just undergone maintenance, a slow drop in engine speed is not considered a fault. The engine speed affects the number of work cycles per unit time or the effective power output of the engine, meaning the engine's effective power varies with different speeds. For the same engine model, the rated power value may differ depending on its application, and the effective torque also changes with engine conditions. The maximum torque output and its corresponding speed are used as indicators to evaluate the engine's performance in automotive applications.

What are the symptoms of a bad CV joint?

Symptoms of a bad CV joint: There will be signs of oil leakage from the dust cover, and abnormal noises or jamming may occur during use. The CV joint, also known as a constant velocity universal joint, connects the axle shaft to the wheel and is a crucial component in the automotive drivetrain system, ensuring continuous power transmission to the wheels in any direction. There are two common types of CV joints used in cars: one is the fixed-type CV joint, which allows only relative rotation between the driving and driven shafts without axial displacement during torque transmission, typically used near the wheel (outer CV joint). The other is the plunging-type CV joint, which not only allows relative rotation but also axial displacement between the driving and driven shafts during torque transmission, usually located near the drive axle (inner CV joint).

How many points will be deducted for occupying the emergency lane?

Occupying the emergency lane will result in a deduction of 6 points. Situations where a motor vehicle driver commits a violation and is penalized with 6 points at a time include: 1. Driving a motor vehicle during the temporary suspension of the motor vehicle driving license; 2. Driving a motor vehicle in violation of traffic signal lights; 3. Driving a motor vehicle on the highway without following regulations under low visibility weather conditions; 4. Obtaining a replacement motor vehicle driving license through concealment or deception. Temporary occupation of the emergency lane is permitted in the following situations: 1. Tire blowout, vehicle brake failure, or steering loss of control; 2. Encountering an accident or fire while driving. The functions of the emergency lane include: 1. Mechanical failure of a motor vehicle rendering it unable to continue normal operation; 2. Passage of privileged vehicles on duty (police cars, fire trucks, ambulances, construction vehicles); 3. Occupancy by the driver or passengers due to urgent physiological conditions (serious life-threatening illness or childbirth); 4. Candidates rushing to an examination.

What are the effects of a damaged inner CV joint in a car?

The effects of a damaged inner CV joint in a car: 1. The vehicle may pull to one side, and steering adjustments may become ineffective, potentially leading to accidents; 2. It accelerates tire wear; 3. In severe cases, it may damage the power steering pump; 4. The steering wheel may lock up, making it impossible to steer. The car's CV joint mainly consists of a sliding sleeve, tripod joint, drive shaft, inner race, cage, and outer housing. The CV joint, also known as a constant velocity joint, transmits power from the transmission to the wheels and ensures that power is transmitted without loss when turning. CV joints are divided into inner and outer joints. When a vehicle makes noise while turning, it indicates a problem with the outer CV joint, possibly due to a damaged dust boot causing oil leakage, which leads to insufficient lubrication and wear of the steel balls and cage inside the joint.

How is running a red light determined?

The method for determining running a red light is: Violation photography requires three photos to determine whether a red light has been run, and none of the three can be missing. The three photos are the vehicle crossing the stop line, the vehicle moving to the middle of the intersection, and the vehicle reaching the opposite side of the intersection, with the third photo being the most important. If you accidentally cross the line when the red light is on and the first or second photo is taken, don't panic. Stop the vehicle and do not continue driving. Wait for the next green light before proceeding, and you won't be captured in the third photo. If you run a red light due to yielding to emergency vehicles like police cars or ambulances on urgent tasks, following the traffic police's instructions, obstructed view by a large vehicle ahead, being rear-ended by another vehicle, or other special reasons, you can appeal the penalty through administrative reconsideration. The traffic police department will review the surveillance footage and the vehicle's route for further determination.
