165/70r13 is a tire specification model, where 165 represents the tire section width in millimeters, 70 indicates the aspect ratio (the percentage of tire thickness to width being 70%), r denotes that the tire has a radial structure, and 13 is the outer diameter of the tire in inches. The impact of tire specifications on a vehicle: 1. Tire width: Affects traction; wider tires generally provide better traction, which is also related to the tire's material composition. Softer materials typically offer stronger traction but reduced durability. Tire width also affects resistance; wider tires increase resistance, leading to higher fuel consumption and slower acceleration. 2. Tread height: Primarily influences shock absorption efficiency and handling feel. 3. Tire thickness: Thicker tires absorb shocks better, filtering out minor vibrations more effectively, while thinner tires provide less vibration filtration, resulting in more direct vibrations. However, thicker tires can make handling less responsive and reduce steering precision.

What are the pros and cons of intercooler pipe modification?

The pros and cons of intercooler pipe modification are as follows: 1. Pros: The intercooler can be used to reduce the temperature of the intake air and increase the density of the intake air, thereby improving the engine's air intake volume and increasing horsepower. 2. Cons: There are side effects, such as piston cracking and piston ring breakage. Relevant information about intercoolers is as follows: 1. Intercooler: Refers to a cooler similar to a radiator, usually located at the front or side of a turbocharged engine vehicle, which cools the air before it enters the engine to lower the temperature and improve intake efficiency. 2. Intercooler: It is a heat exchange container connected between the turbocharger and the intake manifold. Its function is to cool the gas compressed by the turbocharger before it enters the cylinder, with the aim of changing the density of the compressed gas.

Left Turn or Right Turn Priority?

At intersections, vehicles turning left from opposite directions have the right of way, and right-turning vehicles must yield to oncoming left-turning vehicles. This is because left turns are time-limited by traffic signals, and failure to proceed promptly may lead to delays and block straight-through lanes. Right turns, however, are not time-restricted and can be made at any time, requiring extra caution. Right Lane Vehicle Priority: First scenario: If a vehicle in the right lane is going straight, and a vehicle in the current lane is going straight or turning, the right lane vehicle has the right of way. Second scenario: If both the right lane vehicle and the current lane vehicle are turning, the current lane vehicle must yield to the right lane vehicle. This applies to the previously mentioned intersection. Driver A Yielding: If Driver A is traveling south to north on Zhongshan Street and prepares to turn (either left or right) at the intersection, but notices a vehicle approaching from Chengbei Road on the right also intending to turn (either left or right), Driver A must slow down and yield. Current Lane Vehicle Priority: The third scenario occurs when a right lane vehicle is turning while the current lane vehicle is going straight—here, the right lane vehicle must yield to the current lane vehicle. This is the only situation where a right lane vehicle must give way to the current lane vehicle at an intersection.

Should You Lift the Throttle Before Accelerating in an Automatic Transmission?

When accelerating in an automatic transmission, it is necessary to lift the throttle and press it again. The reasons are as follows: 1. Pressing the throttle once: The engine speed will suddenly rise to five or six thousand RPM, but the transmission will not downshift. 2. Pressing the throttle twice: After deeply pressing the throttle the first time and releasing it, pressing the throttle again will cause the transmission to downshift one gear. At this point, pressing the throttle again will make the car more powerful. Information about automatic transmissions is as follows: 1. Types: Hydraulic automatic transmission (referred to as AT), continuously variable transmission (referred to as CVT), and electronically controlled mechanical automatic transmission (referred to as AMT). 2. Characteristics: Cars with automatic transmissions (automatic gearboxes) can automatically adjust speed and torque according to road conditions.

How to Remove Fog from Windows?

Methods to remove fog from windows are as follows: 1. Turn on the car's fan and cooling switch, and the cold air will blow onto the windshield, quickly clearing the fog; 2. Use warm air by parking the car, starting the air conditioning, adjusting the temperature control button to the warm air direction, then selecting the defrost setting to dry the fog with warm air. The reason for windshield fogging is due to the significant temperature difference between the inside and outside of the car in winter. If the driving environment is complex, using the cold air method is preferable as it quickly removes fog from the windshield, preventing visibility issues caused by fogging.

What are the reasons for the fuel pump not receiving electricity?

Possible causes include faults in the fuel injector input and output circuits, such as loose wiring or poor connectors; it may also be burned out due to voltage fluctuations from other parts of the vehicle, resulting in no electricity; or it could be due to its own issues: aging, internal wear, excessive heat from blockage, excessive gap, or poor conduction or burnout due to reaching the end of its lifespan. The function of the automotive fuel pump: The automotive fuel pump is responsible for drawing gasoline from the fuel tank and delivering it through the pipelines and fuel filter to the float chamber of the carburetor, enabling the car engine to start and power the vehicle. It is because of the fuel pump that the gasoline tank can be placed at the rear of the car, away from the engine, and below the engine. Types of fuel pumps: A fuel pump is a lightweight and compact pump, categorized into three main types: in-line, distributor, and unit pumps. The fuel pump requires a power source to operate, with its lower camshaft driven by the engine crankshaft gear. Movable molded parts: The fuel pump features a housing made of aluminum-containing material and a movable molded part installed within the housing. This movable part is at least partially made of a sinterable, iron-based alloy material containing austenite, and the sinterable material of the molded part has a thermal expansion coefficient that is at least 60 percent of that of the housing.

How often should the differential oil be changed for the Vios?

The differential oil for the Vios should be changed every 60,000 kilometers. The differential serves to accommodate the different rotational speeds required by the wheels on either side of the car during turns. The car's differential enables the left and right (or front and rear) drive wheels to rotate at different speeds, primarily consisting of left and right axle gears, two planetary gears, and a gear carrier. The Vios is an entry-level family car specifically designed and developed by Toyota for the Asian market. The Vios is equipped with a domestically produced 16-valve 5AFE engine, which is nearly identical to the commonly used 8A engine in the domestic market, except for an increased piston stroke, raising the displacement from 1.3 liters to 1.5 liters, with a corresponding increase in maximum power to 68 kW.
