What is the normal value of the ignition advance angle?

The normal range for the ignition advance angle is between 6 to 12 degrees. Below is relevant information about the ignition system: 1. Function: In a gasoline engine, as compression nears the top dead center, the combustible mixture is ignited by the spark plug, leading to combustion that performs external work. Therefore, gasoline engines have spark plugs installed in their combustion chambers. The purpose of the ignition system is to generate an electric spark with sufficient energy between the electrodes of the spark plug in the correct sequence for each cylinder. 2. Requirements: The voltage required to produce a spark by breaking down the spark plug electrodes is called the breakdown voltage. The secondary voltage generated by the ignition system must exceed the breakdown voltage for the spark plug to fire. The magnitude of the breakdown voltage is influenced by many factors, including: (1) Spark plug electrode gap and shape: The larger the gap between the spark plug electrodes, the higher the breakdown voltage required; sharp edges on the electrodes reduce the required breakdown voltage. (2) Pressure and temperature of the gas mixture in the cylinder: Higher pressure and lower temperature of the gas mixture increase the breakdown voltage. (3) Temperature of the electrodes: Higher temperatures at the spark plug electrodes reduce the gas density around the electrodes, thereby lowering the breakdown voltage.

Once all settings are complete, release the button. Taking the 2020 Tiggo 3 as an example, its body dimensions are 4420mm in length, 1760mm in width, 1670mm in height, with a wheelbase of 2510mm and a fuel tank capacity of 55l. This car is equipped with a 1.5l naturally aspirated engine, with a maximum power of 85kw and a maximum torque of 143nm, paired with a 5-speed manual transmission.

What is the fuel consumption per 100 kilometers for the Toyota Coaster?

The fuel consumption per kilometer for the Coaster is approximately 0.16 liters. Below are some related details: 1. Toyota Coaster: It is a medium-sized business reception bus produced by Toyota Motor Corporation. The Coaster comes in multiple versions, including the high-grade model (20, 23 seats), the luxury model (10-20 seats), and the 20-seat special executive version. Due to its high reliability and cost-effectiveness, the Toyota Coaster is quite common in many countries and regions, such as Africa, the Middle East, Europe, Australia, and the Caribbean, and is highly favored by minibus operators in Hong Kong. 2. Advantages: The 4.0L gasoline engine provides ample power, strong performance, reduced noise, and improved comfort; powerful acceleration ensures smoother instant speed boosts; robust power also allows for rapid heating inside the vehicle during winter.

Is there a protective plate under the car fuel tank?

There is no protective plate under the car fuel tank. Extended information is as follows: 1. Pros and cons of installing a protective plate for cars: Pros: To protect the engine, especially the oil pan. Cons: It may affect the engine's downward collapse during a collision, as the engine is designed to collapse downward in a crash. Installing a protective plate might hinder this process, potentially leading to more severe injuries to passengers. 2. Reasons why high-end cars are equipped with underbody protective plates: Besides offering some protection to engine components, these plates help maintain the flatness of the chassis, creating a better aerodynamic environment. 3. Deciding whether to install a protective plate based on personal circumstances: 1) Install if driving conditions are poor: If you frequently drive in harsh environments, it's advisable to install one. 2) Not necessary for city driving: If you mainly drive on well-paved roads in the city, installing a protective plate won't make a significant difference. 3) Choose resin or plastic materials: If concerned about affecting the engine's downward collapse, opt for a resin protective plate. Resin or plastic materials offer less resistance during engine collapse.

Where is the carbon canister solenoid valve located on the Jianghuai Refine?

The carbon canister solenoid valve is typically located in the engine compartment of the vehicle. The function of the carbon canister solenoid valve is to reduce air pollution caused by fuel evaporation emissions while simultaneously improving fuel efficiency. When the engine is turned off, the carbon canister begins absorbing fuel vapors evaporating from the fuel tank and securely locks them within the activated carbon micropores inside the canister, preventing the fuel vapors from being released into the atmosphere. Additional information: 1. Content 1: The carbon canister solenoid valve can open, allowing the gas generated by fuel evaporation in the carbon canister to enter the engine's intake manifold. When not required to open, the carbon canister solenoid valve can close. If the carbon canister solenoid valve is damaged, it may affect the engine, causing insufficient power output. 2. Content 2: The carbon canister is generally installed between the fuel tank and the engine. Since gasoline is a highly volatile liquid, the fuel tank often contains vapors at normal temperatures. The fuel evaporation emission control system is designed to direct these vapors into the combustion process and prevent them from evaporating into the atmosphere. The activated carbon canister storage device plays a crucial role in this process.

How to Use Windshield Repair Fluid?

The method of using windshield repair fluid is as follows: First, clean the surface of the car windshield thoroughly and let it dry. Then, insert a blade into the crack to remove glass fragments, gradually cleaning the scratches on the glass. Next, align the crack and drip a small amount of the adhesive into the fracture until the crack becomes less noticeable. Expose the windshield to sunlight for 5 minutes. After the adhesive has cured under sunlight, remove the treatment film and gently scrape off any excess hardened resin with a blade, then wipe clean. More details are as follows: 1. Advantages of Glass Repair Fluid: Windshield repair fluid is a single-component photosensitive resin that can be used for minor glass scratches. It is simple and convenient to operate, with fast curing speed, strong bonding strength, high light transmittance, and leaves no traces or discoloration after bonding. 2. Function: The purpose of windshield repair fluid is to address minor glass scratches, achieving a repair effect that restores the glass to its original condition. The main component of glass repair fluid is photosensitive resin, which repairs the glass without significantly affecting its overall strength. Glass repair fluid is a transparent, odorless, slightly irritating liquid that solidifies upon exposure to ultraviolet light.

Can I sign the driving test score sheet for Subject 3 later if I forgot to sign it?

Subject 3 can be signed later. If you just left the test center and realized you forgot to sign, you can usually go back and sign it. If you remember it long after the test, you can also explain it to the staff at the test center or ask your instructor for help. In most cases, the staff will allow you to sign it later. Here is some additional information: 1. Signing the score sheet does not mean passing the test: But theoretically, whether you pass or fail, you need to receive the score sheet and sign it (electronic score sheets can also be signed). However, in practice, many students who know they failed the test do not collect the score sheet or sign it and leave the test center directly. 2. In most cases, not signing does not matter: According to feedback from some students, not signing after completing Subject 3 generally does not affect the upload of test results. However, it might prevent you from scheduling the Subject 4 test, but this can be resolved by completing the signature later. Additionally, if the signature is missing, the driver's license cannot be issued, so even if you forget to sign, the staff will remind you to sign it later. To be on the safe side, it is best to sign and confirm your score after each test.
