What does vehicle ratio mean?

Why is the car lacking power?

The main reasons for a car lacking power include faults in the fuel system, intake system, exhaust pipe, and electrical system. More detailed information is as follows: 1. Fuel system inspection. With the engine off, loosen the fuel pump's outlet and return ports. When cranking the engine, there should normally be fuel flow, which can be compared to a functioning vehicle. If fuel flow is normal, check the injector return flow. Excessive return flow may indicate internal wear in the injector, causing slow or failed rail pressure buildup. 2. Intake system inspection. Check if the air filter is dirty or clogged, and if the filter element is an authentic part. Inspect all intake pipe connections and hoses for leaks. If necessary, check for excessive dust inside the intake pipe. Ensure the bypass valve opens and closes smoothly to guarantee sufficient air intake. 3. Exhaust system inspection. Check for signs of leaks in the exhaust manifold and ensure the exhaust manifold gasket is intact; replace if necessary. Verify that the exhaust butterfly valve opens and closes smoothly. Perform an exhaust brake action while stationary to observe the valve's movement and determine if it opens and closes fully. 4. Electrical system inspection. Here, the electrical system mainly refers to the ignition system. The electrical system generates high voltage, which is delivered via wires to the spark plugs. The spark plugs ignite the air-fuel mixture in the combustion chamber. Therefore, faulty wires or spark plugs are the most likely causes of poor ignition.

What is the normal service life of tires?

There is currently no official authoritative statement on how long tires last. It is generally believed that the service life of tires is 3 to 5 years, and they should be replaced based on wear conditions within this period. Here are the methods to determine when to replace tires: 1. Tread wear approaching the wear indicator: Any brand of tire will have a wear indicator at the bottom of the tread grooves. The wear indicator height for passenger car tires is generally 1.6 millimeters (this is also the legally mandated minimum groove depth), while for load-bearing tires, the wear indicator height is 2.4 millimeters. 2. Tire damage such as cracks or bulges: Damage to tires includes tread cracks, tread bulges, missing tread rubber, severe sidewall wear, and repeated punctures by foreign objects. Especially with bulges, there is a risk of tire blowout at any time. If any of these damages are found, it is advisable to take the vehicle to a professional tire shop for inspection and timely replacement. 3. Tire age expiration: The service life of tires is typically around 3 to 5 years. Beyond this period, tires begin to age. The main signs of aging are surface hardening and the appearance of cracks. Aged tires lose their elasticity, and continued use can lead to tread deformation, increasing the risk of a blowout.

How to Identify the Tire Wear Indicator Triangle?

On the side tread pattern of a car tire, you can usually find a small triangular arrow indicator. Following this indicator will lead you to a raised mark in the groove of the tire tread pattern, which serves as the tire wear indicator. When the tread depth falls below 1.6 millimeters, typically meaning it is lower than this wear indicator, it generally signifies that the tire is nearing the end of its service life and requires prompt replacement by the vehicle owner. Here is more information about car tires: 1. Continuing to use tires with excessively worn treads poses significant safety hazards. Overly worn tires experience a severe reduction in traction on dry surfaces, especially since front tires usually wear faster than rear tires, potentially leading to understeer (commonly known as "pushing" or "plowing"), which significantly compromises driving safety. Additionally, a tire's water drainage capability relies entirely on its tread pattern. If the tread is too shallow, the tire is prone to hydroplaning and losing control in rainy conditions. 2. It's important to note that tires, being rubber products, undergo aging over time. This aging primarily manifests as numerous small cracks on the tire sidewall. If these cracks have reached the tire carcass, the tire must be replaced regardless of whether it has reached the wear indicator. Otherwise, continuing to use aged tires may risk a blowout.

What Problems Can Water-Damaged Cars Have?

The hazards of water-damaged cars are extremely severe. If a vehicle is submerged in water, it can easily cause rusting of body components, shortening its service life and reducing safety performance. The problems caused by water-damaged cars are as follows: 1. Water-damaged cars can lead to corrosion and rusting of the vehicle's wiring, causing the vehicle to suddenly stall or spontaneously combust due to short circuits while driving, with unimaginable consequences. Additionally, the repair costs for water-damaged vehicles are very high, with repairs for severely water-damaged vehicles typically costing over 50% of the car's value, and insurance claims can be very difficult. 2. There are many channels in a car, and once water enters, it is very difficult to clean, leading to rust over time. The lubricants in components like the four-wheel bearings and half-shafts can deteriorate quickly when soaked in water. Electronic devices in the car, such as the electronic parking brake, audio system, and various sensors, can leave hidden dangers if not repaired promptly after being water-damaged. The most severe case is the engine; after a car has been waterlogged, never attempt to start or turn the engine, as this can cause severe deformation of the engine connecting rods.

What Happens If You Block the Car's Exhaust Pipe?

Blocking the car's exhaust pipe will prevent the car from starting. Here's a detailed explanation: 1. The engine operates in four steps (intake → compression → power → exhaust). When the exhaust is blocked, the intake phase of the next cycle is also hindered, causing the engine to stall. 2. If the pipe isn't completely blocked, starting the engine may not be an issue, but acceleration could become sluggish. Additionally, some engines may increase fuel injection to prevent stalling or boost power, leading to incomplete fuel combustion. This not only negatively impacts fuel efficiency but can also cause severe carbon buildup over time.
