What are the differences between dq380 and dq381?

The differences between dq380 and dq381 lie in the fact that dq381 can reduce engine wear and lower fuel consumption compared to dq380 in terms of performance. Here are the relevant details: 1. In the dq380, the oil pump gear meshes with the clutch gear and is powered by the clutch. Therefore, as long as the clutch is engaged, the oil pump operates, creating oil pressure. This means that under any condition, a portion of the engine's kinetic energy is consumed. In contrast, the dq381's oil pump does not mesh with the clutch but has a dedicated power source. It operates only when oil pressure is needed and stops when not in use, thereby reducing the oil pump's consumption of the engine's kinetic energy. In theory, this also reduces emissions and achieves the goal of lowering fuel consumption. 2. Compared to the dq380, the dq381 incorporates several changes, including the use of lower-viscosity ATF oil, friction optimization for seals and bearings, as well as modifications to the clutch module and hydraulic pump system. In the clutch module, the K1 return spring has been changed from a helical type in the dq380 to a diaphragm type. On the hydraulic side, an additional electric oil pump linked to the CAN bus has been added, controlled via valve adjustments. This supports the hydraulic circuit for clamping the clutch plates and operating the shift mechanism. The oil can also flow to the pressure circuit for lubricating and cooling the shafts, gears, and clutch plates. With the addition of the electric oil pump, the transmission can continue to supply oil to components during start-stop operation and coasting mode without being affected by engine speed, improving the responsiveness of clutch re-engagement when the engine restarts.

What are the 6 steps to inspect a new car?

Verify vehicle information The first step when picking up a new car is to verify the model color and configuration. Generally, there is a metal nameplate near the lower left or right corner of the engine hood. If the production date is from long ago, it might be an inventory car. Move the vehicle to a place with ample sunlight. When inspecting the paint, position yourself at a 45° angle to the area being checked and observe its appearance under sunlight. When inspecting the tires, first check if the tire hairs are fresh.

How many points are deducted for mismatched speed and gear in Subject 3?

Mismatched speed and gear in Subject 3 will result in a direct deduction of 100 points. Shift to 1st gear. Slowly release the clutch to the semi-engaged position. When you feel the car shaking, release the brake immediately. Once you feel the car is no longer shaking, release the remaining clutch and gradually accelerate. Increase the speed to 10-15, even if it exceeds, it should not exceed 20, then shift to 2nd gear. When the speed reaches 20-25, press the clutch and shift to 3rd gear; quickly release the clutch, accelerate to 35 in 3rd gear, press the clutch, and shift to 4th gear.

How to Drive in a Variable Lane?

After entering a variable lane, drivers cannot change lanes again. When the green light for any direction of travel is illuminated at the traffic signal, vehicles in the variable lane must proceed in the direction indicated by the green light. Drive normally as in a straight lane, do not turn left, then make a U-turn at the next intersection or choose an alternative route.

Is it necessary to press the brake when shifting to L gear?

L gear is equivalent to the speed range between first and second gear in a manual transmission. There is no need to shift to L gear when the engine speed is high. However, when driving at low speeds, such as around 20 km/h, it is perfectly fine to directly shift into L gear. Similarly, when going uphill, you can shift from L gear to D gear without pressing the brake - just shift directly. Below are some relevant information about gears: 1. When in L gear, the transmission will stay in first gear and not upshift. It can be used in situations like climbing slopes. It also provides some braking function when going downhill. Some cars have a D2 gear, called low-speed forward gear, which is used for bad roads or off-road conditions. Generally, low gears can be used when climbing steep slopes or starting on inclined surfaces. The principle is that by shifting to this gear, you can limit the car's automatic gear shifting to only low gears (equivalent to first and second gear in a manual transmission car), ensuring the car obtains maximum forward power. 2. L gear is a limiting gear and is best used at low speeds. When shifting from D gear to L gear, if the current speed is higher than what first gear requires, it will automatically switch to the corresponding gear (such as L3 or L4 gear, with the corresponding value displayed after the L gear on the information screen). If shifting to L gear at low speeds, it may be L1 gear. If you need to increase the gear, press the '+' button on the left side of the gear lever to shift to the desired gear. Similarly, if the gear is too high, press the '-' button to lower it to the appropriate gear. When climbing steep slopes or driving on snow, shifting to L gear can enhance the car's climbing and passing ability. During long downhill drives, shifting to a lower L gear can use engine braking to limit speed, reducing the safety risks associated with frequent braking in D gear. This has the same effect as downshifting in a manual transmission when going downhill. 3. L gear can also be used for prolonged low-speed driving in urban areas, such as when following traffic. Firstly, it can reduce engine speed, preventing the engine and transmission from overheating. Secondly, it reduces frequent start-stop intervention, as start-stop only works in D gear and not in L gear. During normal driving, use D gear, as at the same speed, fuel consumption in L gear is higher than in D gear.
