Can People with High Blood Pressure Learn to Drive?

Yes, they can. Here are some precautions for individuals with high blood pressure when driving: 1. Take adequate breaks: Avoid long-distance driving and minimize continuous driving time. Take a break of at least 10-15 minutes every two to three hours and stay hydrated. 2. Ensure sufficient cardiopulmonary oxygen supply: Avoid getting angry in poor road conditions or heavy traffic. You can sing or listen to soothing music. Singing loudly can enhance gas exchange and provide more oxygen to the heart and lungs. In areas with severe traffic congestion and poor air circulation, keep the car windows closed as much as possible, as harmful gases from exhaust emissions may irritate blood vessels, causing spasms and potentially triggering heart disease. 3. Limit driving frequency: Control the number of times you drive, preferably not exceeding three days a week. If symptoms like dizziness or chest tightness occur while driving, promptly park the car in a safe area and call 120 for assistance. Lastly, it is important to remind individuals with high blood pressure to regularly monitor their blood pressure and take antihypertensive medication as prescribed.

Why Do Vehicles Use Urea?

Vehicles use urea primarily to meet emission standards. Urea usage scenarios: Only diesel vehicles require urea. National regulations mandate that electronically controlled diesel engine vehicles must use urea because diesel vehicles emit higher levels of exhaust gases. Adding urea helps reduce carbon oxides in the exhaust, lowering pollutant emissions and making diesel vehicles more environmentally friendly. Technical requirements: Most modern diesel engines employ selective catalytic reduction (SCR) technology. This means that after the engine exhaust exits the turbocharger but before entering the vehicle's exhaust pipe, it first passes through a catalytic converter for transformation. The urea injector on the exhaust pipe sprays urea under the control of the vehicle's computer.

Does a small car need to undergo an on-site inspection in its sixth year?

The vehicle in its sixth year requires an on-site inspection during the annual inspection. Below is relevant information about vehicle inspections: 1. Timing of vehicle inspections: If you purchased a new car and it is still within 6 years, it can be exempted from inspection twice (every two years, you need to apply for an inspection mark without requiring an on-site inspection); in the 6th and 8th years, the vehicle must undergo an on-site inspection. For private cars over 10 years old, the original inspection cycle still applies, i.e., annual inspections for cars between 10 and 15 years old, and semi-annual inspections for cars over 15 years old. 2. Notes regarding motor vehicles: The owner of the motor vehicle can apply for an inspection compliance mark from the local vehicle management office within 3 months before the expiration of the motor vehicle inspection validity period. Motor vehicle safety technical inspection institutions must inspect the motor vehicle according to national motor vehicle safety technical inspection standards and bear legal responsibility for the inspection results.

What is the Difference Between Car Batteries and Electric Vehicle Batteries?

Car batteries and electric vehicle batteries differ in type, current voltage, and purpose. Below are the relevant introductions about batteries: 1. Differences in type: Car batteries are starting-type batteries, while electric vehicle batteries are power-type batteries, also known as traction batteries. 2. Differences in current voltage: Car batteries have high current and low voltage, whereas electric vehicle batteries have high voltage and low current. 3. Differences in purpose: Car batteries are used for cars, and electric vehicle batteries are used for electric vehicles. A battery is a type of storage battery, also known as an accumulator, whose working principle is to convert chemical energy into electrical energy. The batteries commonly referred to by people are lead-acid batteries, which mainly use lead and its oxides as electrodes and sulfuric acid solution as the electrolyte. 4. Classification of batteries: Batteries are divided into three categories: ordinary batteries, dry-charged batteries, and maintenance-free batteries.

Why is there abnormal noise when releasing the throttle but not when accelerating?

Abnormal noise when releasing the throttle but not when accelerating is due to issues with the car's half-shaft. Reasons for the buzzing sound when pressing the accelerator: It's not an engine problem, but rather caused by loose nuts on the front drive shaft; The device on the internal combustion engine that controls fuel supply; The throttle pedal is also known as the accelerator pedal. Introduction to hazard handling: In case of throttle pedal issues during new car operation, don't panic. As professionals suggest, fully depress the brake pedal to stop the vehicle, then turn off the engine and contact for assistance. When climbing a slope, avoid fully depressing the throttle pedal; when using low gear, it's generally advisable to press the throttle halfway.
