Common Causes of Car Faults?

Common causes of car faults: 1. Abnormal car noises: Car noises are the most common, especially interior noises (ceiling, A/B pillars, dashboard, etc.). If these noises are not too loud, it's best not to address them, as handling them might make the situation worse. 2. Unpleasant odors in the car: These are mainly caused by the smells from various components in the cabin. Most parts contain plastic and other materials, and the mixture of these odors creates the unpleasant smell inside the car. 3. Abnormal operating conditions: Sudden abnormal phenomena during car use should be given special attention, such as the engine suddenly stalling; brakes failing to work; sudden loss of steering while driving, etc. It's important to take these seriously and visit the nearest service station for inspection. 4. Engine overheating: Engine overheating is mainly caused by insufficient coolant, faulty radiator cap or thermostat, loose or broken fan belt, blocked coolant passages, or insufficient oil in the lubrication system.

Definition of Hybrid Vehicles

Hybrid vehicles refer to automobiles equipped with two or more power sources, also known as composite power vehicles. Below is a detailed introduction to the types of hybrid vehicles: 1. Parallel configuration: This setup uses the engine as the primary power source, with the electric motor serving as an auxiliary power assist. 2. Series-parallel configuration: In this system, the vehicle is driven solely by the electric motor at low speeds, while the engine and electric motor work together at higher speeds. 3. Series configuration: This type uses only the electric motor to drive the vehicle. The main components of hybrid vehicles include: storage batteries, fuel cells, solar cells, and internal combustion engine generators.

How Old Should a New Car Be When Purchasing?

It is generally advisable to purchase a car that has been manufactured no more than six months before the delivery date; otherwise, it may be considered stock inventory. Here are some key considerations when buying a car: 1. Be Wary of Excessive Discounts: While everyone wants to buy their desired car at the best price, be cautious if the discount seems unusually large or the final price is significantly lower than expected. Remember, dealerships don't operate at a loss, so be vigilant to avoid falling into traps set by unscrupulous sellers. 2. Have a Target Model Before Visiting a Dealership: Without a specific model in mind, you may be swayed by salespeople's recommendations and end up with a car that doesn't suit your needs or preferences. 3. Pay Attention to Contract Details: When signing any contracts during the car-buying process, carefully review every clause. If anything is unclear, insist on a clear explanation from the salesperson. Never sign anything without fully understanding the terms. 4. Choose an Appropriate Price Range: Before purchasing, carefully consider your budget and choose a car that fits within your financial means.

Can Turbocharged Engines Use 92 Octane Gasoline?

Some turbocharged models can use 92 octane gasoline, but it is recommended to follow the official vehicle owner's manual. In addition to checking the suitable gasoline grade in the owner's manual, you can also find this information on the fuel tank cap. The fuel tank cap will usually indicate the recommended octane rating. Generally, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95 octane gasoline. For higher compression ratios, 98 octane gasoline is recommended. However, with the use of new technologies, the compression ratio alone cannot determine the appropriate gasoline grade. High-compression engines can also be tuned to use lower-octane gasoline due to other influencing factors such as ignition timing, turbocharging technology, and Atkinson cycle technology. Generally, the higher the gasoline octane rating, the higher the octane number and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. Occasionally using the wrong gasoline grade is not a problem—simply switch back to the correct grade after the tank is empty. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles designed for low-octane gasoline, using a higher octane rating will not cause damage, but the increased octane number may alter the fuel's ignition point, leading to delayed combustion in the engine. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. For vehicles designed for high-octane gasoline, using a lower octane rating can cause engine knocking. Since the octane number is significantly lower, the gasoline's ignition point decreases, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance will develop during the upward stroke. This resistance makes the engine run very unevenly. If the knocking is mild, it may only increase noise without obvious engine damage. However, noticeable knocking indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring.

Can Fuel Savers Really Save Fuel?

Fuel savers can achieve fuel-saving effects. The working principle is: The automobile fuel saver automatically generates the current required by the water-powered fuel saver host through the power controller, electrolyzing the water in the water-powered fuel saver host into hydrogen and oxygen. The hydrogen-oxygen mixed gas is then delivered to the engine's cylinders through the safety isolation water supply device and pipelines, where it burns together with other fuels to perform work, thereby achieving the fuel-saving effect. Extended content: Classification of fuel savers: 1. Solid-state fuel catalysis and air oxygen-enrichment type: The product uses solid-state physical fuel and air catalysis. During operation, it can automatically clean the carbon deposits in the fuel system and injectors, achieving the best atomization effect of the injectors and promoting complete fuel combustion, thereby improving thermal efficiency. It truly enhances power, reduces noise pollution, and saves fuel. 2. Oxygen-enrichment type: It uses the vehicle's DC power to ionize air under high voltage to produce O3, which is ozone, and then delivers this gas to the engine to increase the oxygen supply.

Why Can't Refrigerant Be Added to the Car Air Conditioner?

The reasons why refrigerant cannot be added to the car air conditioner, whether at high or low pressure, are as follows: 1. Blocked connection: If high and low pressure readings can be observed, it indicates that the issue of blocked high and low pressure pipe connections can be ruled out. 2. Compressor damage: If the low-pressure side is high and the high-pressure side is low, it may indicate compressor damage. In such cases, refrigerant cannot be added. The most common symptom of a dirty or blocked expansion valve is frosting. 3. Poor heat dissipation: If the opening is small, the low-pressure pipe will not feel very cold when touched by hand. If the opening is large, the low-pressure pipe will feel very cold. Additionally, a dirty condenser causing poor heat dissipation or a failed dryer bottle can also lead to this phenomenon.
