Can I Replace Tires Purchased Online by Myself?

You cannot replace tires purchased online by yourself because after installing new tires, wheel balancing is required. Without proper wheel balancing, the vehicle cannot be driven safely. Wheel balancing requires specialized equipment, making it impossible to perform at home. The reasons for needing wheel balancing are as follows: 1. Reason one: There are manufacturing tolerances in tires, and the wheel hubs or brake drums may have inaccurate axial positioning during processing. 2. Reason two: The quality of wheel bolts may vary. 3. Reason three: Tires may experience wear, become out of round, or deform. 4. Reason four: After off-road driving, mud stuck to the tires may increase the weight of certain parts.

What is a Fuel Pump?

A fuel pump is a lightweight and compact pump, mainly categorized into three types: in-line, distributor, and unit pumps. It requires a power source to operate, with the camshaft at its lower part driven by the engine crankshaft gear. The fuel pump features an aluminum alloy housing and a movable molded component inside it. Here is more detailed information about fuel pumps: 1. The plunger is the key component of the injection pump: To draw an analogy with a common medical syringe, the movable plunger is equivalent to the syringe's piston, and the syringe barrel is like the plunger sleeve. If a spring is installed inside the barrel pushing against one end of the plunger while the other end contacts the camshaft, the plunger moves up and down once within the sleeve for every full rotation of the camshaft. This is the basic operational mechanism of the injection pump plunger. 2. The plunger and plunger sleeve form a highly precise matched pair: The plunger has an inclined groove, and the sleeve features a small hole called the suction port, which is filled with diesel. When the plunger's groove aligns with the suction port, diesel flows into the sleeve. As the camshaft lifts the plunger to a certain height, the groove and port misalign, sealing the port and trapping the diesel. Further upward movement pressurizes the diesel until it overcomes the check valve's resistance, forcing the diesel through the injector nozzle into the combustion chamber.

What to Do When Driver's License Points Are Insufficient?

If the points on your driver's license are insufficient, the only option is to revoke the license and retake the driving test. Below are the relevant regulations regarding driving: 1. Violations: Driving a vehicle that does not match the permitted vehicle type; Driving under the influence of alcohol; Operating a passenger transport vehicle (excluding buses) or school bus with passengers exceeding 20% of the approved capacity; Fleeing the scene after causing a traffic accident without constituting a crime; Driving a vehicle on the road without a license plate or intentionally covering, damaging, or improperly installing the license plate, etc., will result in a 12-point deduction. 2. Driver's License: For a Class C license, accumulating 12 points requires retaking the theoretical exam (Subject 1). Only after passing the exam can you drive legally. Driving during this period is considered unlicensed driving, so it's risky to drive. For Class A and B licenses, accumulating 12 points will result in an immediate downgrade. The local traffic management office will revoke the highest permitted driving qualification and process the downgrade and license replacement within 30 days. For holders of Class A and B licenses, if more than 6 points but less than 12 points are deducted during the probation period, the probation period will be extended by one year. The same rule applies to Class C licenses. However, if 12 points are deducted during the probation period, the probationary driving qualification will be revoked.

What does 'push' mean on a truck?

Truck's 'push' refers to the exhaust brake button. Here are the specific details about its meaning: 1. Introduction: Exhaust brakes are widely used in large diesel vehicles. A regulating valve is installed on the engine exhaust pipe, and the pressure during the exhaust stroke is increased by closing this valve, utilizing the generated negative pressure to obtain braking force. 2. Usage method: The exhaust brake is generally activated by a manual switch. To prevent engine stalling when stopping and to avoid exhaust brake operation during fuel injection, the exhaust brake is automatically released when the accelerator pedal or clutch pedal is pressed.

Can You Take the Remaining Driving Test Subjects Without a License?

Whether you can obtain a driver's license after driving without one depends on the severity of the offense. If no traffic accident occurred and you only received administrative penalties, it generally does not affect obtaining a driver's license. However, if you caused a traffic accident while driving without a license and fled the scene, constituting a criminal offense, you will be permanently barred from applying for a driver's license. Article 101 of the Road Traffic Safety Law states the following: 1. Point one: Violating road traffic safety laws and regulations, causing a major traffic accident that constitutes a crime, will result in criminal liability and the revocation of the driver's license by the traffic management department of the public security authority. 2. Point two: Fleeing after causing a traffic accident will lead to the revocation of the driver's license by the traffic management department of the public security authority, with a lifetime ban on reapplying for a driver's license.

Driving with or without polarized sunglasses?

Driving with polarized sunglasses is better. Here are the specific details: 1. Regular sunglasses: Primarily function by reducing light intensity, diminishing glare and UV rays. Since their lenses cannot filter light, they cannot completely block these harmful rays. Their main purpose is to reduce eye strain. 2. Polarized sunglasses: Due to their polarized nature, they can completely block dazzling glare caused by scattering, refraction, reflection, and other factors. They fully block UV rays harmful to human eyes, making long-term activities in bright light less fatiguing for the eyes, achieving true eye protection. Additionally, they provide clearer and more three-dimensional vision.
