What car brand has an inverted 7 logo?

The inverted 7 logo represents Luxgen and Lexus. Luxgen is the transliteration of 'LUXGEN', which is a fusion of the English words 'Luxury' and 'Genius'. Below is an introduction to Lexus cars: 1. Lexus is a brand under Japan's Toyota Motor Corporation. Lexus (English: Lexus; Japanese: レクサス) was established in 1983 and is a globally renowned luxury car brand under the Toyota Group. 2. Performance: The Lexus L-finesse design aesthetic, combined with F1 aerodynamic testing, gives the IS F a dynamic and sporty style. Two raised lines extend downward from the base of the A-pillar, glide past the sides of the grille, and outline the contours of the large front air intakes on the front bumper. The high waistline design running through the body, the elongated cooling vents behind the front wheel arches, and the four exhaust pipes at the rear all reveal the high-performance essence of the IS F.

What are the requirements for upgrading from C2 to B1 license?

You can apply for a B1 license upgrade if you have held the license for three years and have not accumulated 12 penalty points in the last three years. After completing the required training and passing the three driving tests (Subjects 1, 2, and 3), you will obtain the B1 license. Below is relevant information about license upgrading: 1. Upgrade matters: To upgrade your license, you must have a local household registration in the area where you wish to upgrade, and the license issuing authority must also be local. If you do not meet these conditions, the upgrade will not be processed, and you will need to transfer your license relationship. All types of driving licenses require the completion of the probationary period before they can be upgraded. 2. Scoring cycle: After adding a new driving category and obtaining a new license, the validity period of the license will not be recalculated. Additionally, the scoring cycle always starts from the original license's initial issuance date. It is important to note that during the probationary period after the upgrade, if your license accumulates 12 penalty points, the probationary driving qualification for the new category will be revoked.

Can a Turbocharged Car Be Turned Off Immediately?

Turbocharged cars should not be turned off immediately. Reasons for stalling: Automatic transmission models: Automatic transmission models are less likely to stall, while manual transmission models may stall frequently due to poor driving skills. However, it is not impossible for automatic transmission cars to stall, mainly due to the use of low-quality fuel leading to engine carbon buildup and stalling. Precautions: For automatic transmission cars stalling, the main reason is the use of low-quality fuel. First, refuel at reputable, larger gas stations with higher-grade fuel, such as using 97-octane gasoline. Although it is more expensive, it ensures a longer lifespan for your car and better performance while driving.

Should You Shift to Neutral at Traffic Lights in an Automatic Car?

When waiting at traffic lights in an automatic car, it is advisable to shift to neutral (N) and engage the handbrake for added safety. Using N gear with the handbrake can also save fuel, as the passive wheel in the transmission is in an idling state, thereby reducing fuel consumption. Avoid shifting to P (Park) while waiting at traffic lights, as shifting from P to D (Drive) may cause the car to reverse, potentially disrupting traffic behind you and increasing the risk of a rear-end collision, for which you may bear some responsibility. Similarly, keeping the car in D gear with the foot brake applied is not ideal, as the fixed connection between the engine and the transmission's passive wheel creates a counterforce on the driving wheel, increasing the engine's load. This can be understood as hindering the engine's operation, prompting the ECU to increase fuel injection, leading to higher fuel consumption. Shifting Precautions: Do not press the accelerator pedal while shifting gears; avoid immediately pressing the accelerator pedal hard after shifting; the engine can only be started in P or N gear; to move the gear lever out of P, the brake must be pressed; do not shift to N while driving to coast; never shift to P while the car is moving; when changing direction between D and R, ensure the car is completely stopped before shifting; placing the gear in N while driving prevents normal fuel supply for lubrication, which can raise the temperature of internal transmission components and cause damage.

What are the types of lubricating oil?

Lubricating oil models are classified as: 0W, 5W, 10W, 15W, 20W, 25W. Low ignition energy causing vibration: When the engine temperature is too low, both fuel and lubricating oil are cold. During cold starts, a richer air-fuel mixture is required, which in turn demands higher ignition energy. Excessive spark plug gap or aging ignition coils and high-voltage coils can reduce ignition energy, leading to vehicle vibration. Incorrect air-fuel mixture ratio causing vibration: During cold starts, significant errors in signals from certain engine sensors or some sensors can lead to ECU miscalculations. This results in inaccuracies in fuel injection timing and ignition timing control, causing engine vibration. Uneven cylinder conditions causing engine vibration: In multi-cylinder engines, large variations in ignition energy among cylinders, along with differing degrees of piston and piston ring wear leading to inconsistent compression ratios, can cause uneven engine power output and result in engine vibration.

Why is the reversing sound of hybrid vehicles particularly loud?

Hybrid vehicles have particularly loud reversing sounds due to engine-related reasons. Traditional Ignition: The working process of a mechanical ignition system involves the crankshaft driving the distributor shaft to rotate. The cam on the distributor shaft rotates, causing the primary contacts of the ignition coil to open and close, thereby generating high voltage. This high-voltage ignition current is then distributed by the rotor on the distributor shaft to the spark plugs of each cylinder in the required sequence, where the spark plugs generate sparks to ignite the gas in the combustion chamber. Electronic Ignition: Electronic ignition systems are entirely different from mechanical ignition systems. They include an electronic control device for ignition, which contains ignition control curves (MAP graphs) required for various engine operating conditions. A series of sensors, such as engine speed sensors, intake manifold vacuum sensors (engine load sensors), throttle position sensors, and crankshaft position sensors, are used to determine the engine's operating state.
