There are several reasons why a car motor may not start: insufficient battery power or dirty starter terminals causing poor contact, leading to the starter not turning; a broken electromagnetic switch coil in the car starter; issues with internal components of the starter; or a fault in the anti-theft system. 1. Car Motor: The electronic starter is what people commonly refer to as the motor, also known as the starter. 2. Notes: When the starter carbon brushes are severely worn, the symptom during startup is weak starting, and the crankshaft can be seen turning very slowly through the belt and pulley. If the wear is extremely severe, the starter may not be able to turn the crankshaft at all, only producing a buzzing sound of current.

How Big is a Car's Fuel Tank?

Generally, the fuel tank capacity of small cars is 35-45 liters, while that of medium-sized cars is 55-75 liters. A full tank typically allows for a driving range of around 500 kilometers. Depending on the engine displacement of the car, vehicles with higher fuel consumption have larger tanks, while those with lower consumption have smaller tanks. During the actual refueling process, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity specified by car manufacturers is measured from the bottom of the tank to the safe fill level. There is additional space from the safe fill level to the tank opening, which is designed to accommodate fuel expansion due to rising temperatures without causing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added can exceed the calibrated tank capacity. To check the remaining fuel level, drivers can observe the fuel gauge on the right side of the dashboard, which is marked with 'E' and 'F'. When the needle is close to 'E', it indicates low fuel, while nearing 'F' means the fuel level is sufficient.

What procedures are required at the DMV for car color changes?

Changing the color requires registering the modification of the vehicle's color at the DMV. The necessary documents for applying to change the vehicle's body color include: the "Motor Vehicle Modification Registration Application Form," identification documents of the vehicle owner and agent, the vehicle registration certificate, and the vehicle's license. According to Article 6 of Chapter 2 of the "Road Traffic Safety Law," if the area of color change does not exceed 30%, there is no need to register the modification. Conversely, if it exceeds 30%, it must be filed and registered within 10 days after the color change. Precautions for changing vehicle wrap colors: Before preparing to change the color of the vehicle wrap, it is necessary to consult the local DMV where the vehicle is registered to check if the region permits changing the vehicle's color using wraps. If the region does not support this method, the modification cannot be filed after the change, and the wrap must be completely removed to restore the vehicle's original color. Additionally, according to the "Motor Vehicle Registration Regulations," owners are no longer required to apply to the DMV in advance. They can first change the vehicle's color, install body kits, replace the engine, etc., and then apply to the DMV for modification registration. According to Article 10, registered motor vehicles must apply for modification registration under the following circumstances: Changing the body color. Replacing the engine. Replacing the body or frame. Replacing the entire vehicle due to quality issues. Changing the use nature, such as converting a commercial vehicle to a non-commercial vehicle or vice versa. The vehicle owner's residence moves out of or into the DMV's jurisdiction. Furthermore, according to Article 15 of the "Road Traffic Safety Law of the People's Republic of China": Police cars, fire trucks, ambulances, and engineering rescue vehicles must spray emblem patterns and install alarms and signal lights as required. Other motor vehicles are not allowed to spray, install, or use emblem patterns, alarms, or signal lights that are exclusive to or similar to those of the aforementioned vehicles. Article 56 of the "Motor Vehicle Registration Regulations" states that if the body color is changed without registering the modification as required, the public security traffic management department will issue a warning or impose a fine. The vehicle may also be impounded and required to revert to the original body color.

What are the differences between Toyota Izoa and CH-R?

The differences between GAC Toyota CH-R and FAW Toyota Izoa: 1. Price: The FAW Toyota Izoa is slightly more expensive than the GAC Toyota CH-R. 2. Fuel consumption: Both cars have a fuel consumption of 4.7L per 100 kilometers. 3. Exterior: There are slight differences in the lower grille on the front face, and the rear badges are also different. Below is additional information about the GAC CH-R and FAW Izoa: 1. Exterior: The Izoa and CH-R are very similar, but they can be distinguished by the lower grille on the front face. The Izoa features a simpler horizontal bar design with a silver lower guard, while the CH-R retains the overseas model's design with a more refined honeycomb grille. Of course, apart from the front face, you can also quickly identify the Izoa and CH-R by their rear badges. 2. Features: The Izoa comes with additional features compared to the CH-R, including cruise control, adaptive cruise control, adaptive high/low beam, automatic emergency braking, lane departure warning, and a larger central control screen.

What are the wheel specifications for the Mondeo?

The 18-inch wheel model for the Mondeo is 235/45R18. Here, 235 represents the tire's section width of 235 millimeters, 45 indicates the aspect ratio (the percentage of the tire's section height divided by its width), R stands for radial tire, and 18 denotes the rim diameter of 18 inches. The new Mondeo uses aluminum alloy wheels for the following reasons: The new Mondeo employs aluminum alloy wheels, which have gained increasing popularity among private car owners due to their aesthetic appeal, safety, and comfort. Maintenance methods for aluminum alloy wheels: When the wheel temperature is high, allow it to cool naturally before cleaning. Never use cold water for cleaning, as this can damage the aluminum alloy wheel and even deform the brake disc, affecting braking performance. Additionally, using cleaning agents on hot wheels can cause chemical reactions on the surface, leading to loss of luster and reduced aesthetics. For stubborn tar stains on wheels, try using a brush if regular cleaners are ineffective. A home remedy for removing tar: Apply medicinal "Huoluo Oil" for surprisingly effective results—worth a try. In humid environments, clean the wheels frequently to prevent salt corrosion on the aluminum surface. If necessary, apply wax after cleaning to maintain the wheel's shine.

What kind of car is Fujiwara Takumi's AE86?

Fujiwara Takumi's AE86 is a Toyota Trueno GT Apex (AE86). The AE86 is a model from Toyota's compact car series called the Corolla. AE86 is not a name but a chassis code. The AE86 is the fourth-generation Corolla model first produced in 1983. Previous models included the TE27, TE51, TE55, TE61, TE65, and TE71, followed by the AE86 chassis. This chassis was used not only in the Corolla Levin but also in the Trueno, hence the distinction between pop-up and fixed-headlight AE86 variants. The AE86 also came in two-door and two-door hatchback versions, essentially offering four body styles, all referred to as AE86. They shared major components like the engine and transmission, with the most significant difference being the rear differential (DIFF). The AE86 features a front-engine, rear-wheel-drive layout and has a relatively heavy body. Its rear-wheel design uses a non-independent solid axle with a single trailing arm suspension. This configuration gives the AE86 an inherent advantage in drifting, as it offers greater agility, making it highly suitable for drifting.

What does the G value mean?

The G in cars is a unit of gravity, with g representing more, mainly gravitational acceleration. During vehicle testing, there are two sets of data: lateral and longitudinal. The lateral data indicates the side-slip limit of the car when turning, commonly understood as the relationship between the vehicle's speed and the angle of the curve without causing side-slip. This represents the vehicle's handling performance. The longitudinal data indicates the vehicle's performance during acceleration and deceleration, i.e., the maximum capacity for speed increase and braking. A car with a higher g value performs better. For general-use vehicles, the maximum and minimum longitudinal values can be achieved, but the lateral values, due to the risk of losing control, are rarely achieved by anyone other than professional drivers. The full vehicle value of a car: This refers to the length and tonnage of the vehicle, charged as a single fee. The vehicle is delivered to a specified location individually, with the fee based on the full vehicle price, equivalent to a charter price. The ECU of a car: ECU (Electronic Control Unit), commonly known as the "onboard computer," is a specialized microcomputer controller for cars, also called the car's dedicated computer. When the engine is running, the ECU collects signals from various sensors, performs calculations, and converts the results into control signals to manage the controlled objects. The inherent program continuously compares and calculates with the signals collected from the sensors during engine operation. The results of these comparisons and calculations control multiple parameters of the engine, such as ignition, idle speed, and exhaust gas recirculation. It also has self-diagnostic and protective functions. The memory continuously records driving data, forming the ECU's learning program to provide optimal control states adapted to driving habits, known as the adaptive program.
