What is the function of the crankshaft?

The function of the crankshaft is to: receive the force transmitted by the connecting rod and convert it into torque, which is then output through the crankshaft to drive other engine accessories. The crankshaft is subjected to the combined effects of centrifugal force from rotating masses, periodically varying gas inertial forces, and reciprocating inertial forces, causing it to bear bending and torsional loads. To reduce the mass of the crankshaft and the centrifugal force generated during operation, the crankshaft journals are often made hollow, with oil holes drilled on the surface of each journal to allow the introduction or removal of oil for lubricating the journal surfaces. To minimize stress concentration, the connections between the main journals, crankpins, and crank arms are all designed with transition arcs.

What does the ECO on the Grand Cherokee center console mean?

ECO stands for the car's economical driving mode function. ECO is an English abbreviation formed by combining 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 lights up, it indicates that the vehicle's economy mode has been activated. Eco mode is categorized into active and non-active types. The difference lies in the fact that the active mode has its own dedicated button, allowing the driver to choose whether to enable it. When the driver presses the ECO mode switch, the dashboard indicator light immediately illuminates, and the vehicle automatically begins adjusting settings such as throttle opening, transmission shift logic, and air conditioning output power. Non-active ECO mode does not have a dedicated button. When the dashboard ECO indicator light turns on, it serves merely as a reminder. 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 vehicles use the active ECO driving mode, meaning they have a dedicated switch button. Therefore, during daily driving, you can enable ECO mode. However, it is unnecessary to activate ECO mode when driving at speeds exceeding 120 km/h, during idle parking, in N/P gear, or in manual mode—especially when climbing hills. Doing so would not reflect the fuel-saving characteristics of ECO mode and could also affect performance. Additionally, ECO mode typically becomes ineffective under the following conditions: When the vehicle speed exceeds 120 kilometers per hour, the system prioritizes speed, causing the ECO mode to automatically deactivate. During idle parking or when in N/P gear or manual mode, 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 operate.

How to Avoid Stalling on the Slope Start in Subject 2?

The steps for the slope start in Subject 2 are: depress the clutch, depress the brake, engage first gear, and release the handbrake. At this point, the right foot on the brake should remain steady, while the left foot slowly lifts the clutch. When reaching a certain position, you can begin to feel the car body shaking. Simultaneously, release the brake while keeping the clutch steady, and the foot on the brake can add some throttle to assist. This way, the car will start without stalling. More information on slope start is as follows: 1. The slope start in Subject 2 requires achieving two points: no stalling and no rolling back. To achieve these, the clutch and brake must be controlled perfectly, meaning the semi-engaged state must be just right. Releasing the brake too early with insufficient clutch pressure will cause the car to roll back due to lack of braking force. Releasing the brake too late or failing to stabilize the clutch can easily lead to stalling. 2. Depress the brake, slowly release the clutch until you feel the car body shaking, creating a sensation like an arrow ready to be released. Then, slowly release the brake while keeping the left foot steady on the clutch. When the brake is released, the car should move forward instead of rolling back. This semi-engaged feeling of an arrow ready to be released needs to be sensed and controlled by intuition. With more practice, you can find the right feeling.

Can a Modified Grille Pass the Annual Vehicle Inspection?

Modifying the grille cannot pass the annual vehicle inspection. If the modification of the car's grille is registered in advance with the vehicle management office and the photo on the vehicle license is also updated, it can pass the inspection; if not registered in advance and the photo on the vehicle license remains unchanged, it will fail the inspection. The car must match the photo on the vehicle license. Any discrepancy between the car and the photo on the license is considered unauthorized modification, which is illegal. Regarding car modifications, Chinese law clearly stipulates that vehicle owners do not need to apply for modification registration under the following conditions, provided that safety and license plate recognition are not affected: 1. Installation of front and rear anti-collision devices on small and mini passenger vehicles; 2. Installation of windshields, water tanks, toolboxes, spare tire racks, etc. on cargo vehicles; 3. Addition of interior decorations to the vehicle.

What is the appropriate cold tire pressure for an SUV?

The recommended cold tire pressure for an SUV is generally within the range of 2.2-2.5 bar. However, to determine the exact normal tire pressure for your specific SUV model, you should refer to the vehicle's user manual or check the manufacturer's recommended values indicated on the label near the door (around the B-pillar or C-pillar). Hazards of overinflated tires: 1. Excessive tire pressure reduces tire friction and adhesion, negatively impacting braking performance and shortening tire lifespan. 2. Overinflation decreases puncture resistance, increasing the risk of blowouts. 3. Accelerates uneven wear on the central tread pattern, reduces tire durability, amplifies vehicle vibration, and indirectly affects the longevity of other components. 4. Overinflation causes excessive stretching deformation of tire cords, reduces tire elasticity, increases driving load, and weakens puncture resistance. When encountering sharp objects like nails or glass, the tire becomes more susceptible to penetration, internal cracks, and explosive blowouts. Hazards of underinflated tires: 1. Low pressure increases fuel consumption, makes steering heavier, causes alignment issues, damages bead areas, causes abnormal wear, reduces tire strength, and may lead to blowouts during high-speed driving. 2. Insufficient pressure increases movement in all tire parts, causing excessive rolling that generates abnormal heat, degrading cord and rubber functionality, leading to delamination or cord breakage, and creating excessive friction between the rim and bead area. 3. Multiplies friction with the road surface, causing rapid temperature rise, tire softening, drastic strength reduction, and potential blowouts during high-speed driving.

What are the reasons for the bankruptcy of Brilliance BMW?

The reasons for the bankruptcy of Brilliance BMW are as follows: 1. Improper marketing strategies: Engaging in price wars that lowered its brand value, and failing to implement timely and effective rescue measures, leading to a decline in consumer confidence. Therefore, enterprises must follow market rules, base their actions on reality, and plan for the long term. 2. Failure to utilize advantageous resources properly: Not making good use of available resources, over-relying on BMW, and failing to absorb and integrate technology, instead turning itself into a manufacturing plant for BMW. This resulted in a lack of competitive strength against other brands, ultimately leading to unavoidable bankruptcy and restructuring.
