What is the difference between a 1.5T and 1.5L car engine?

The displacement of 1.5T and 1.5L refers to the nature of the car's engine. L stands for a naturally aspirated engine, while T represents a turbocharged engine. 1.5T indicates a 1.5-liter turbocharged engine, and 1.5L represents a 1.5-liter naturally aspirated engine. The differences between 1.5T and 1.5L: 1. In terms of power: 1.5T is undoubtedly better than 1.5L. Under the same displacement, engines with "T" are generally much more powerful than those with "L". 2. In terms of fuel consumption: Generally, the fuel consumption of 1.5L models is lower than that of 1.5T models. This is because vehicles with "L" engines intake air while drawing fuel, resulting in lower fuel consumption. 3. Reliability: Engines with "L" have been used for a longer time, making the technology more mature and thus more reliable. 4. Maintenance costs: (1) The reliability of 1.5L engines is relatively high, and the failure rate during use is relatively low, so daily maintenance costs are relatively lower. (2) In contrast, for 1.5T engines, when the car's mileage reaches 150,000 kilometers, the turbocharger may need to be replaced. Moreover, the maintenance costs for "T" engines are higher, significantly increasing the overall maintenance expenses.

How many points will be deducted for a C1 driver with less than one year of experience driving on the highway?

C1 drivers with less than one year of experience are not penalized with points for driving on the highway, as it is permitted. However, the prerequisite is that they must be accompanied by a driver who has held a corresponding or higher-level driving license for more than three years. Otherwise, if caught driving alone on the highway, they will face a fine and be ordered to exit the highway at the nearest point. For those preparing to enter the highway, they will be educated and advised to turn back. Tips for new drivers on the highway: 1. Conduct a thorough vehicle inspection before driving, especially checking fluids, tires, lights, etc., and plan the route in advance to avoid confusion later; 2. Highways have speed limits, with a minimum speed not less than 60 km/h and a maximum speed not exceeding 120 km/h; 3. Pay attention to road signs. If you miss an exit, stay calm, do not attempt to brake suddenly or make a U-turn. Instead, maintain your speed and proceed to the next exit to return to your original route; 4. Avoid fatigue driving. If you feel drowsy, take a break at the nearest service station.

What is a Service Brake?

Service brake is the braking system of a car, which can slow down and stop the vehicle while it is moving. Brakes are divided into service brakes (foot brakes) and parking brakes (hand brakes), and consist of several components such as the brake pedal, push rod, master cylinder, wheel cylinder, brake drum, brake shoe, brake backing plate, friction lining, brake shoe return spring, and oil pipe. During driving, the service brake (foot brake) is generally used to facilitate slowing down and stopping while moving forward. The parking brake not only keeps the car stationary but also serves as a backup in case the service brake fails. Once the car comes to a complete stop, the parking brake (hand brake) should be applied to prevent the vehicle from sliding forward or rolling backward.

What is the latest method to permanently disable auto start-stop?

The latest method to permanently disable auto start-stop: 1. Start the car after exposing it to direct sunlight until the displayed temperature exceeds 35 degrees Celsius; 2. Open the engine auto start-stop disable interface, where the function will already be in a deactivated state; 3. Long-press the engine auto start-stop disable icon until the small yellow bar disappears, indicating activation, then release; 4. After a few seconds, the small yellow bar will reappear, meaning the function has been disabled again. At this point, the operation is complete, and even if the temperature drops, the auto start-stop will remain disabled. Subsequently, when starting the car in cold weather, the auto start-stop will still be in a disabled state.

How to Use Clutch and Brake When Going Downhill?

How to use clutch and brake when going downhill depends on the road conditions: 1. If the slope is very small and short, you can directly use the brake to control the speed; 2. If the slope is steep and long, you should shift to a low gear in advance to use the engine to control the speed, while also using the brake to assist in deceleration. When going downhill, pay attention to checking the braking performance to eliminate potential safety hazards. Before descending, ensure the vehicle enters the downhill section at a controllable speed, and shift to an appropriate low gear according to the slope. Regardless of the slope, it is not recommended to coast in neutral. Properly utilize the engine's braking effect to reduce the vehicle's inertial speed. It is advisable to use intermittent braking (pumping the brakes) on downhill sections. If the slope is too long, find a suitable place to stop midway and check the temperature of all four wheels.

What is the dumbest method for hill start and stop?

What is the dumbest method for hill start and stop: 1. Observe the point at one-third of the right side of the engine hood. When it aligns with the roadside line, the distance between the car body and the roadside is about 30 centimeters; 2. Continue to control the speed with the clutch half-engaged, slowly approaching the stopping point. When the lower edge of the left rearview mirror aligns with the second thick yellow line, first press the foot brake, then press the clutch to stop the car steadily. Hill start and stop is a key assessment point in the second subject of the driver's test. Test requirements: The test requires parking at a fixed position on a slope with a gradient of at least 10% and a length of at least 30 meters, assessing the coordination of steering, braking, and clutch. The purpose is to train drivers to accurately judge the position of the vehicle and correctly use the brake, gear, and clutch to meet the needs of stopping and starting on uphill sections.
