What is the difference between L4 and V6?

The differences between L4 and V6 are reflected in the following two aspects. Introduction to L4: L4 has lower manufacturing cost, smaller weight, and compact size. Its maintenance cost and difficulty are also lower. Simpler structures like the valve train mean less internal friction, giving it an advantage in fuel economy. However, its secondary vibrations cannot self-balance, resulting in significant operational vibrations. Except for a few high-performance models, most L4 engines are tuned to emphasize low-end torque. Yet, the 180-degree power stroke interval makes torque output less smooth at low RPMs. Overall, the refinement is not as good as (V6). Introduction to V6: V6 has higher manufacturing cost, larger weight, and bigger size. Its maintenance cost and difficulty are also higher. The additional internal friction caused by its complex structure can only be offset by higher fuel consumption. However, V6 can self-balance both primary and secondary vibrations. The power stroke interval is reduced to 120 degrees, meaning it can adapt better to both high and low RPM ranges. Overall, the refinement is better (than L4).

Where is the Mercedes-Benz Parking Button?

The Mercedes-Benz automatic parking system is built-in and does not have a button; it automatically activates as soon as the engine starts. After stopping the car, press the brake firmly (similar to an emergency stop where the brake is pressed all the way down). At this point, you can see the car enter HOLD mode. Relevant information about the automatic parking system is as follows: 1. Introduction: Automatic parking, also known as AUTO-HOLD, refers to an automatic braking function. Once activated, for example, when stopping at a traffic light, there is no need to pull the handbrake. This simplifies operations by avoiding the use of the handbrake or electronic handbrake, and for automatic transmission models, it eliminates the need for frequent switching between D to N or D to P. 2. Working Principle: The AUTO-HOLD automatic parking function provides precise parking force through a slope sensor controlled by the system. During startup, the parking control unit calculates information from the clutch distance sensor, clutch engagement speed sensor, throttle pedal sensor, etc. When the driving force exceeds the running resistance, the parking brake is automatically released, allowing the car to start smoothly.

What does the shift key on a car mean?

On a car, the shift key refers to the shift lock. For automatic transmission models equipped with this button, the gearshift cannot be moved when the engine is off. By locking the gear, it ensures no gear skipping or disengagement, enhancing driving safety. Unable to shift gears: If shifting is impossible due to various malfunctions, you can press the SHIFT-LOCK button on the gearshift console with a thin, hard object like a needle to move the gear from P to N. Shift-Lock is also a specialized device for unlocking under specific circumstances, such as when the vehicle cannot start due to a dead battery. In this case, if the vehicle is in P gear and cannot be towed, pressing the shift-lock button allows the gear lever to move to N gear, enabling the vehicle to be towed. Generally, any automatic transmission vehicle will have this feature. Switching gears: Previously, automatic transmission models lacked this function, allowing the gear to be shifted from P to R, N, or even D even when the engine was off. However, in newer models, due to the Shift-Lock feature, shifting gears when the engine is off is impossible. This helps to some extent in preventing the vehicle from sliding when stationary due to accidental gear shifts.

How many points are deducted for gear mismatch in Subject 3?

Subject 3 gear mismatch deducts 10 points. Subject 3 exam gear and speed usage: first gear at 0-15 km/h, second gear at 15-25 km/h, third gear at 20-35 km/h. As long as the examinee switches between the specified speed and gear, and the gear matches the speed, it is acceptable. Below are specific introductions to car shifting techniques: Downshift after deceleration: Increase the speed before upshifting, and reduce the speed by releasing the throttle before downshifting. Before shifting, the clutch pedal must be fully depressed, and the gear lever should be operated lightly, quickly, gently, and accurately. Master the timing of shifting: Shift when the engine speed is around 2000 RPM. Press the accelerator first and then the clutch, so the clutch won’t be forced to disengage, then shift. Downshift according to the speed. Generally, downshift when the engine speed is below 1500 RPM. The shifting action should be smooth: Depress the clutch fully in one motion, and shift gears in one step. Familiarize yourself with the gear positions. If you encounter difficulty shifting into gear, shift to neutral, release the clutch slightly, and depress the clutch again to shift into gear.
