What is a Crankcase?

The crankcase is the lower part of the cylinder block where the crankshaft is installed, divided into the upper crankcase and the lower crankcase. The upper crankcase is cast integrally with the cylinder block, while the lower crankcase is used to store lubricating oil and seal the upper crankcase, hence it is also referred to as the oil pan. Components of the Crankcase: The upper crankcase is cast integrally with the cylinder block, while the lower crankcase is used to store lubricating oil and seal the upper crankcase, hence it is also referred to as the oil pan. The oil pan bears minimal stress and is typically made from stamped thin steel sheets. Its shape depends on the overall engine layout and the capacity of the engine oil. Functions of the Crankcase: The oil pan is equipped with an oil stabilizer baffle to prevent excessive oil surface fluctuations when the vehicle is jolted. Additionally, the bottom of the oil pan is fitted with a drain plug, which usually contains a permanent magnet to attract metal particles from the lubricating oil, thereby reducing engine wear. A gasket is installed between the joint surfaces of the upper and lower crankcases to prevent lubricating oil leakage.

What are the key points for driving on curves?

Curve driving techniques are as follows: Align the vehicle before entering: Before entering an S-curve, try to align the vehicle straight. When you see the angle between the left A-pillar and the lower edge of the windshield align with the left edge of the road, it indicates the vehicle is in the middle of the S-lane. Determine the steering timing: Observe the first node of the windshield wiper. When this node reaches the right edge line, turn left one full rotation. Then, slightly adjust the steering to keep this node on the edge line. Maintain this position while driving. When the first node of the wiper reaches the left edge line, straighten the steering wheel. Drive with the steering wheel straightened: Continue driving with the steering wheel straightened. When the second node of the wiper reaches the left edge line, turn right one full rotation. Similarly, slightly adjust the steering to keep the second node on the edge line and maintain this position while driving slowly.

What are the reasons for crossing the line when turning right during curve driving?

Curve driving right turn crossing the line may be caused by incorrect steering timing, misjudgment of vehicle trend, and other reasons. Incorrect steering timing: When turning, failing to observe the reference point and steer in time, or not grasping the right timing, can cause the car to veer too far to the right and cross the line. Misjudgment of vehicle trend: Lack of vehicle sense and incorrect judgment of the vehicle's movement trend can lead to crossing the line. Curve driving test techniques: In principle, try to take a wider path after entering the curve; when in the curve, use the steering wheel to keep the small rearview mirror on the inner side of the hood always at the edge of the outer white line (specifically, not crossing the line or staying too far from the edge line), and straighten the direction at the end of the S-curve. Avoid using the brake, especially emergency braking.

What does the white zigzag line mean?

White zigzag lines are distance confirmation lines. There are three types of distance confirmation lines: white zigzag distance confirmation lines, white semicircular distance confirmation lines, and highway distance confirmation markings. White zigzag distance confirmation lines: The total width of white zigzag distance confirmation lines is 300 cm, with line widths of 40 cm or 45 cm. Starting from the base point at 0 meters, a line is set every 5 meters, with two lines forming a group, spaced 50 meters apart. Five groups are typically repeated, though more may be set depending on site conditions. White semicircular distance confirmation lines: White semicircular distance confirmation lines have a hemisphere radius of 30 cm and are spaced 50 meters apart, usually set continuously over a certain section of the road. Highway distance confirmation markings: These markings are used in conjunction with distance confirmation signs and are placed in sections where overtaking is common, accidents are frequent, or other needs arise. The purpose of highway distance confirmation markings is to remind drivers to maintain a safe following distance when they see these markings, thereby preventing traffic accidents.

What Causes the Engine Light to Illuminate While Driving?

When the engine light illuminates while driving, it could be due to engine knocking, among other reasons. The causes and solutions are as follows: Detailed Causes: The vehicle's warning light typically illuminates due to issues with the fuel emission system; poor engine combustion state; engine knocking; poor fuel quality; dirty engine cylinder interiors with carbon deposits; the computer's inability to retrieve engine data; or false faults. Solutions for Engine Warning Light Illumination: Promptly inspect the condition of the car's engine; check the status of the vehicle's sensors, including the air flow sensor and spark plug components; inspect for any knocking in the engine; and examine the ignition coil for faults.

Where is the engine number of a new energy vehicle?

New energy vehicle engine numbers are stamped on the cylinder block of the engine, typically on both sides at the rear of the block. It usually consists of a combination of 7 to 8 digits and letters. In addition to the above method, the engine number can also be checked through the following 4 ways: The vehicle driving license contains the engine number, usually located on the second last line; The motor vehicle registration certificate will state the engine number; The car purchase invoice will state the engine number; The vehicle purchase tax payment certificate will state the engine number. It should be noted that the engine number is not the same as the engine model. The engine model refers to the specifications and size of the engine within the manufacturer, and engine models can be the same. The engine number refers to the production number of the engine, each engine can only have one engine number and each engine's number is unique.
