Iridium spark plugs are better, mainly for the following reasons: 1. Their high melting point allows them to be used in various high-power engines, tolerating higher temperatures without electrode melting or burning out. 2. Their high hardness enables the electrodes to be made thinner. Thinner electrodes provide more concentrated ignition, stronger energy, and more stable spark paths, effectively improving combustion efficiency and effectiveness. Additional benefits of iridium spark plugs include: 1. Enhanced performance: Sufficient ignition energy and stable spark points increase output power and improve dynamic performance. 2. Smooth operation: Excellent combustion and strong explosive power boost engine speed, making the engine run more smoothly. 3. Quick ignition: Low ignition voltage and reduced electrical suppression enable faster ignition. 4. Fuel savings: Good combustion conditions and high instantaneous output power allow for lower fuel consumption while maintaining the same output power.

What does 'tripa' mean on the car dashboard?

Car dashboard 'tripa' refers to the trip odometer, which measures the mileage of each trip taken by the user. Here is some related information about car dashboards: 1. Basic introduction: Different cars have different instrument panels. However, common gauges in most cars include the speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, and charging gauge. 2. Oil pressure: The sensor for the oil pressure gauge on the car dashboard is a piezoresistive sensor. It is fixed to the engine oil pipeline with threads. The oil pressure pushes the contact piece to move along the resistor, changing the resistance value, which in turn affects the current flowing through the gauge to the ground, driving the pointer to swing.

What to Do If You Keep Crossing the Line During Curve Driving?

If you keep crossing the line during curve driving, you can remember five key points for steering wheel control to pass smoothly. Here are the detailed steps: 1. Point One: After entering the S-curve, observe carefully. When the hood overlaps with the right-side curve, turn the steering wheel one full turn to the left. 2. Point Two: As the vehicle continues forward, when the left front of the car overlaps with the right-side curve, turn the steering wheel half a turn to the left, then make slight adjustments to keep the front of the car always overlapping with the curve. 3. Point Three: Before entering the right turn, observe when the left front of the car aligns with the left-side curve, straighten the steering wheel. 4. Point Four: As the vehicle enters the right curve, when one-third of the left front hood aligns with the curve, turn the steering wheel one full turn to the right. 5. Point Five: Continue observing. When the right front of the car overlaps with the left-side curve, start turning the steering wheel half a turn to the right, then make slight adjustments to keep the front of the car always overlapping with the left-side curve. Finally, when exiting the curve, ensure the front of the car is straight and the steering wheel is centered.

What is the speed limit on provincial highways in general?

Provincial highways generally have speed limits ranging from 60 to 80 km/h. Below is additional information regarding speed regulations: 1. Speed regulations: The speed limit for passenger vehicles on highways is 120 km/h, while for trucks it is 100 km/h. In China, pickup trucks are classified under the truck category, with a maximum speed limit of 100 km/h on highways. 2. Penalties for speeding: For passenger vehicles, speeding less than 20% results in a warning. Speeding between 20-50% incurs a fine of 200 RMB and 3 penalty points. Speeding between 50-70% results in a fine of 1,000 RMB, 6 penalty points, and possible revocation of the driver's license. Speeding over 70% leads to immediate revocation of the driver's license and a fine of 2,000 RMB.

What Does the Car Engine Oil Light Warning Mean?

Here are the reasons for the car engine oil light warning: 1. Insufficient oil level: The oil pump's output decreases due to low oil volume, ultimately leading to a drop in oil pressure and triggering the oil light warning. 2. Engine overheating: Prolonged aggressive driving keeps the engine in a high-temperature and high-load state. Even if the oil level is sufficient, excessive heat thins the oil, causing it to leak through the gaps and resulting in reduced oil pressure. 3. Oil pump failure: Similar to the previously mentioned owner's issue, excessive wear or improper assembly of the oil pump components creates large gaps. When the oil pump malfunctions, it either fails to pump oil or pumps insufficiently, triggering the oil light warning.
