The key light flashes red because the smart key is not detected, and the smart key is not detected due to insufficient battery power in the key. In this case, car owners need to replace the battery. Here are some related details: 1. The Sylphy is a compact sedan under the Nissan brand. 2. The Sylphy is equipped with a 1.6-liter naturally aspirated engine, codenamed HR16. This engine has a maximum power of 102 kW, a maximum torque of 169 Nm, a maximum power speed of 6300 rpm, and a maximum torque speed of 4000 rpm. 3. This engine features multi-point fuel injection technology and uses an aluminum alloy cylinder head and block. It is paired with either a 5-speed manual transmission or a CVT transmission. The CVT transmission is compact, lightweight, simple in structure, and low in production cost. Many Japanese cars frequently use CVT transmissions. The CVT transmission allows the engine to maintain a reasonable speed range, so cars equipped with CVT transmissions are generally more fuel-efficient.

How many bearing seats are required for a triangular chassis?

Triangular chassis requires a total of 3 bearing seats. Below is relevant information about automotive bearings: 1. Introduction: A bearing is a mechanical element that restricts relative motion within the desired range of movement and reduces friction between moving parts. The design of bearings can provide free linear movement of moving parts or free rotation around a fixed axis, and can also prevent motion by controlling the vector of normal forces acting on moving parts. 2. Sliding bearings: The simplest type of bearing is the sliding bearing, which consists of a shaft rotating within a hole. Lubrication is used to reduce friction. In ball bearings and roller bearings, rolling elements with circular cross-sections (rollers or balls) are placed between the races or journals of the bearing assembly to reduce sliding friction.

How Many Days of Practice Before Retaking the Subject 2 Driving Test is Most Suitable?

Generally, it is advisable to practice driving 2-3 days in advance. Starting too early may cause you to forget key points. The practice duration should not be too long; about 2 days is sufficient. Over-practicing can make it harder to correct bad habits or mistakes. On the day before the test, practicing once or twice is enough to avoid fatigue, which could affect your performance the next day. Also, ensure you get adequate rest and sleep. Different items in Subject 2 have different deduction points. The details are as follows: 1. General Deductions: Not wearing a seatbelt, not closing the car door properly, and not having the gear in neutral when starting the engine will each deduct 100 points. Not using the turn signal, using the turn signal for less than 3 seconds, forgetting to turn it off, or using it incorrectly, as well as stalling the engine, will each deduct 10 points. 2. Parallel Parking: If the vehicle exceeds the line after stopping in the parking space or if the task takes more than 90 seconds, 100 points will be deducted. Not using or incorrectly using the turn signal when exiting the parking space will also deduct 100 points. Touching the parking space line with the car body or running over the lane boundary line with the wheels during movement will deduct 10 points each time. Stopping for more than 2 seconds during the process will deduct 5 points each time. 3. Reverse Parking: If the task takes more than 210 seconds, not following the prescribed route or sequence, not driving the front wheels over the control line before reversing, or failing to park properly in the space will each deduct 100 points. Stopping for more than 2 seconds during the process will deduct 5 points each time. 4. Curve Driving: Running over the edge line or stopping for more than 2 seconds will each deduct 100 points.

Can an Electronic Turbocharger Enhance Power?

An electronic turbocharger can indeed enhance power. Generally, a turbocharger can increase power output by approximately 30%. It operates by utilizing the inertial force of exhaust gases expelled by the engine to drive a turbine within the turbocharger housing. This turbine, in turn, rotates a coaxial impeller, which compresses incoming air from the air filter intake and forces it into the engine cylinders under increased pressure. Below is relevant information about turbochargers: 1. Advantages: The primary benefit of a turbocharger lies in its ability to significantly boost engine power and torque without necessitating an increase in engine displacement. After installing a turbocharger, engine power and torque typically increase by 20% to 30%. 2. Disadvantages: The main drawback of turbochargers is lag. Due to the inertia of the impeller, there's a delayed response to sudden throttle changes, resulting in a lag in power output adjustment. This means vehicles requiring sudden acceleration or overtaking may experience a momentary sensation of insufficient power.

Why doesn't the electric vehicle move when it gets wet in the rain despite having power?

The reasons why an electric vehicle doesn't move after getting wet in the rain despite having power are as follows: 1. Water ingress or poor contact in the controller: When the controller gets wet, it cannot receive electricity, causing the electric vehicle to fail to move or the rear wheel to lock; If the controller gets wet, it is essential to promptly open the controller, dry it with paper or a cloth, wipe the circuit board with alcohol, and then let it dry before sealing and testing it. If it still doesn't work, replace the controller immediately. 2. Poor line contact: Loose battery connections or poor contact in the power lines, check if the battery terminals are corroded or loose. 3. Water ingress in the battery: Insufficient power in the electric vehicle, water ingress in the battery can lead to insufficient discharge output current.

What does 'Please Check Engine Control System' mean?

It indicates that there may be a fault in the engine, and a diagnostic tool is required to read the fault codes for further diagnosis and repair based on the codes. Engine Electronic Control System: 1. Ignition Control: This system determines the engine's operating conditions and status based on signals from relevant sensors, selects the optimal ignition timing to ignite the air-fuel mixture, thereby improving the combustion process to enhance engine performance, fuel efficiency, and reduce emissions. 2. Idle Speed Control: This is an auxiliary control system of the engine. Its function is to control the engine's air intake via the idle speed control valve during idle conditions, based on factors such as engine coolant temperature, whether the air conditioning compressor is operating, and whether the transmission is engaged, ensuring the engine operates at the optimal idle speed at all times. 3. Emission Control: Its primary function is to electronically control the operation of the engine's emission control devices. Emission control measures mainly include: Exhaust Gas Recirculation (EGR) control, charcoal canister solenoid valve control, oxygen sensor and air-fuel ratio closed-loop control, secondary air injection control, etc.

What is the size of the front windshield for the 2021 Buick Excelle?

The front windshield size of the 2021 Buick Excelle is 4mm in thickness with an area of 1050mm*1050mm. Below are the detailed specifications: 1. Windshield Introduction: Another type of safety glass, widely used in modern car side and rear windows. Compared to laminated glass, tempered glass increases strength through heating and pressurization. When damaged, it shatters into smooth, small particles resembling breadcrumbs, reducing the likelihood of injury from glass fragments. Unfortunately, tempered glass is not suitable for repair or repositioning, making it ideal for completely damaged side and rear windows. 2. Function of the Windshield: Laminated glass involves bonding a transparent adhesive plastic film between two or three layers of glass, combining the toughness of plastic with the hardness of glass to enhance its resistance to breakage. Tempered glass is made by quenching ordinary glass to form internal stresses, thereby strengthening the glass. Upon impact, it breaks into small fragments with blunt edges, minimizing the risk of injury to passengers.
