What is the difference between Corolla EX and Corolla?

What is the fuel tank capacity of the Buick Excelle 2013 model?

The fuel tank capacity of the Excelle 2013 XT 1.6L manual comfort version is 60L. The vehicle is equipped with a 1.6L naturally aspirated engine and a 5-speed manual transmission (MT). The drivetrain configuration is front-engine, front-wheel drive. The front suspension type is MacPherson independent suspension, while the rear suspension uses a compound torsion beam non-independent suspension. Among vehicles in the same class, the Nissan Sylphy 2022 Classic 1.6XE manual comfort version has a fuel tank capacity of 50L, and the Volkswagen Lavida 2022 1.5L manual fashion version has a fuel tank capacity of 51L. During actual refueling, the amount of fuel may exceed the calibrated capacity. This occurs because automakers measure fuel tank capacity from the tank bottom to a safe fill level, leaving additional space between this safe level and the tank opening. This design accommodates fuel expansion due to temperature increases, preventing overflow. If fuel is filled up to the tank opening during refueling, the actual fuel quantity will exceed the nominal tank capacity. To check remaining fuel levels, drivers can observe the fuel gauge on the right side of the instrument panel, marked with E (Empty) and F (Full). When the needle approaches E, it indicates low fuel, while proximity to F signifies sufficient fuel levels.

What Causes the Engine Malfunction Light to Illuminate While the Vehicle Can Still Operate Normally?

The illumination of the engine malfunction light may serve as a warning, indicating that certain system parameters in the vehicle may have exceeded the set range. In such cases, the vehicle can usually continue to operate, and the light is typically yellow. There is also a more severe scenario where the light turns red, indicating a very serious malfunction. Although the vehicle might still be operable, for safety reasons, it must be stopped immediately, the engine turned off, and further driving prohibited until the fault is inspected. There are primarily seven reasons for the engine malfunction light to illuminate: Sensor Failure: This includes sensors such as coolant temperature, crankshaft position, air flow, intake temperature, and oxygen sensors. When these sensors are damaged, have poor contact, or signal interruptions, the vehicle's ECU cannot accurately obtain engine data, triggering the malfunction light. Fuel or Oil Quality Issues: Failure to use the fuel or oil as specified by the manufacturer may lead to engine wear, causing the malfunction light to illuminate. Poor Combustion of Air-Fuel Mixture: This can result in engine carbon buildup or knocking. Once detected by the oxygen sensor and reported to the ECU, the malfunction light will illuminate as a warning. Issues like spark plug failure, ignition coil failure, fuel pump failure, or clogged fuel lines can all lead to poor combustion. Turbocharger Issues: Problems with the intake boost system or turbocharger can also trigger the malfunction light. The most common issue is turbocharger damage, often accompanied by symptoms like oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake System Problems: Blockages in the engine's intake system can lead to serious issues, causing the malfunction light to illuminate. A dirty air filter that hasn't been cleaned regularly can also cause intake problems. Exhaust System Issues: Exhaust faults can trigger the malfunction light. Common causes include faults in the rear oxygen sensor, catalytic converter, exhaust camshaft, or bearings, with the catalytic converter being the most frequent issue. Using leaded gasoline, lead or silicon-based lubricant additives, physical damage to the catalytic converter, or fuel system malfunctions can all contribute to catalytic converter failure. Anti-Theft System Malfunction: If the vehicle's electronic anti-theft system fails or if there is a mismatch between the anti-theft controller and the engine ECU, the anti-theft system can prevent the engine from operating normally, and the malfunction light will illuminate. If the engine malfunction light illuminates, follow these steps: First, check if the engine is running normally and look for signs like shaking or smoke. If present, avoid restarting the engine. Note: Never restart the engine if the light is red. If the engine can be started, turn it off and wait 5-10 minutes. Without pressing the brake, press the start button once or turn the key halfway to the 'on' position without depressing the clutch. The vehicle will perform a self-check upon powering up. Observe the dashboard after 5-10 seconds to see if the malfunction light turns off. If the light remains on, visit a service center as soon as possible. Technicians can use a portable diagnostic tool to read the fault codes, identify the issue, and perform targeted repairs.

What is the sequence for releasing the handbrake and shifting gears when starting?

Starting sequence for handbrake and gear shifting: When starting, you should first shift into gear, then release the handbrake. Below are precautions for starting: 1. Check surroundings: Honk the horn, turn on the turn signal, and observe the front, sides, and rearview mirrors to check for pedestrians or vehicles behind, ensuring there are no obstacles to starting. 2. Key to smooth starting: Mastering the timing of the clutch semi-engagement and coordinating closely with the accelerator pedal. When releasing the clutch pedal, start slightly faster, and when approaching the point where the engine sound changes and the car body slightly vibrates, pause the clutch pedal briefly at this position.

Start the Engine First or Release the Handbrake First?

You need to step on the brake first; the order of ignition and handbrake release does not have much impact. Below is relevant information about the handbrake: 1. Principle: The professional term for the handbrake is auxiliary brake. Unlike the principle of the main brake, the handbrake uses a steel cable connected to the rear brake shoes to brake the vehicle. Long-term use of the handbrake will cause the steel cable to undergo plastic deformation. Since this deformation is irreversible, prolonged use will reduce its effectiveness, and the handbrake's travel will also increase. 2. Supporting Tools: The handbrake is used in conjunction with a return spring. When the handbrake is engaged, the spring is stretched; when the handbrake is released, the spring returns to its original length. With long-term use, the spring will also undergo corresponding deformation.

Is a small puncture in the tire serious?

If it does not affect the tire pressure, it means only the surface of the tire is damaged, and you can drive normally. However, if it affects the tire pressure, it may cause a blowout, and the tire must be repaired. Below is more information about car tire pressure: 1. Introduction to tire pressure: Strictly speaking, it refers to the pressure of the air inside the tire. In car maintenance, the engine is the heart of the car, and damage to the engine will lead to the end of the car's life. Similarly, tire pressure is the blood pressure of the car, and the level of tire pressure plays a crucial role in the performance and power of the car. 2. Normal tire pressure range for vehicles: It is appropriate to keep it around 2.3~2.5, especially in summer when temperatures are high, it is best not to exceed 2.5.

What is the difference between National II and National III?

The difference between National II and National III is that National III is more environmentally friendly than National II. Major domestic engine manufacturers have begun developing their own EGR engines to meet the National III emission standards and satisfy market demand. The EGR engine is a transitional engine from National II to National III emission stages. The true National III engine is the high-pressure common rail engine. Relevant information about automotive emission standards is as follows: 1. Introduction: Automotive emission standards refer to regulations on the content of harmful gases such as CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), and PM (particulates, soot) emitted from vehicle exhaust. 2. Implementation: Starting from January 1, 2004, Beijing changed the tailpipe emission standards for motor vehicles from Euro I to Euro II. By 2008, the Euro III standard was officially implemented.
