What Causes Diesel Fuel to Burn Poorly?

Diesel fuel burns poorly due to slight deviations in spark plug ignition timing, impurities in the air filter, and other factors. Reasons related to diesel fuel: Poor diesel quality: The performance indicators of the diesel used do not meet standard requirements, leading to incomplete combustion and black smoke. Additionally, low-quality diesel can damage the diesel filter, causing the diesel inside the engine to degrade, which results in black smoke. Clogged air intake: Diesel engine fuel tanks are not sealed, and prolonged exposure to air inevitably allows impurities and dust to enter the air filter. These particles can clog the air intake, preventing sufficient air supply during diesel combustion, which easily leads to incomplete combustion and black smoke. Insufficient compression: One of the conditions for diesel combustion is a pressurized environment. However, wear on components like valves and piston rings can reduce compression pressure, failing to meet combustion requirements. This worsens combustion conditions, leading to black smoke. Solutions: Modern fuels are high-cleanliness products with various additives to aid combustion and meet emission standards. Three years ago, diesel from Shandong refineries typically had a density above 0.85g/m³, with some even reaching 0.88g/m³ or 0.89g/m³. The higher density allowed for more complete combustion of heavier components, making the diesel feel more powerful. However, with increased crude oil refining in Shandong, the root cause of high density has been addressed. Additionally, the proportion of heavy components like catalytic diesel has significantly decreased, and post-hydrotreatment diesel density has dropped considerably.

Where is the child lock switch on the Nissan Sylphy?

The child lock switch on the Nissan Sylphy is located on the lock mechanism of the rear door. There is a movable lever that can be toggled to engage the child lock. Toggling it again will allow the door to be opened. The Nissan Sylphy has body dimensions of 4641mm in length, 1815mm in width, and 1447mm in height, with a wheelbase of 2712mm. Its fuel tank capacity is 47 liters, and it features front-wheel drive. The child lock, also known as the door child safety lock, is installed on the rear door locks. To activate it, open the rear door and locate a small lever beneath the door lock. Push the lever toward the side with the child icon, then close the door. Once engaged, the door cannot be opened from the inside and can only be opened from the outside. This feature is designed to prevent curious or restless children from opening the door while the vehicle is in motion, thereby avoiding potential dangers. The door can only be opened from the outside by an adult after the vehicle has stopped.

Can You Stick Your Head Out During Curve Driving?

Curve driving does not allow sticking your head out, otherwise it will result in failure. During the Subject 2 driving test, candidates are not permitted to lean their heads out of the window to check vehicle operations; they must rely solely on rearview mirrors for observation. According to test regulations, not only is leaning out prohibited, but no part of the body may extend outside the vehicle during any movement test. Violation will result in failure. The Subject 2 driving test consists of five tasks: reverse parking into a garage, hill start, parallel parking, curve driving, and right-angle turns. Among these, reverse parking and parallel parking require controlling the vehicle by observing the rearview mirrors. Relevant officials have also stated that under the new traffic regulations, not only is leaning out prohibited, but no part of the body may extend outside the vehicle during any movement test. Violation will result in failure. Tips for curve driving: When entering an S-curve, pay attention to the position of the front of the car. When the midpoint of the front touches the right yellow line, gradually steer to the left. Start with half a turn, keeping the left corner of the front aligned with the yellow line. When the left corner is about to cross the yellow line, steer a bit more. If the left corner fails to touch the yellow line, slightly adjust the steering back. When the front of the car is centered at the curve junction, quickly straighten the steering, usually requiring about one full turn. When the midpoint of the front touches the left yellow line, steer half a turn to the right, then make minor adjustments, following the curve and continuously adjusting the steering wheel. While turning, use peripheral vision to glance at the left and right rearview mirrors to monitor the distance between the rear wheels and the boundary lines, making appropriate adjustments to avoid crossing the lines.

What is ECO mode?

ECO refers to the economic driving mode of a car. ECO is an English abbreviation derived from the combination of Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The Eco mode is further divided into active Eco driving mode and non-active Eco driving mode. When the Eco indicator light on the dashboard illuminates, it indicates that the vehicle's economic mode has been activated. The Eco mode can be categorized into active and non-active types. The difference lies in the fact that the active type has its own dedicated button, allowing the driver to choose whether to activate it. When the driver presses the Eco mode switch, the dashboard indicator light immediately turns on, and the vehicle automatically begins adjusting settings such as throttle opening, transmission shift logic, and air conditioning output power. The non-active Eco mode does not have a dedicated button. When the Eco indicator light on the dashboard illuminates, it serves merely as a reminder function. The Eco system automatically evaluates your driving behavior. If your current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the Eco indicator light. Most cars utilize the active Eco driving mode, meaning they have their own switch button. Therefore, during daily driving, we can activate the Eco mode. However, it is unnecessary to enable the Eco mode when the speed exceeds 120 km/h, during idle parking, in N/P gear, or in manual mode, especially when climbing hills. Doing so would not only fail to demonstrate the fuel-saving characteristics of the Eco mode but also negatively impact the vehicle's power performance. Additionally, the Eco mode typically becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the car prioritizes speed, causing the Eco mode to automatically deactivate. During idle parking or when in N/P gear or manual mode, the Eco mode may also become ineffective. When high torque output is required, such as when climbing a hill, the engine control unit prioritizes ensuring sufficient power to drive the vehicle, and the Eco mode will not function under these conditions either.

How to Set the Three Modes of Changan UNIT?

You can switch modes by entering the function menu on the dashboard. In NORMAL driving mode, the power output is neither sluggish nor fuel-consuming. The power response is slightly delayed, and the power output feels constrained, which may frustrate impatient drivers. The powertrain becomes more responsive, making the car more enjoyable to drive. Using SPORT driving mode + manual gear shifting can enhance the driving experience.
