Is Higher or Lower Tire Pressure Better in Summer?

Lower tire pressure is better in summer. Generally, the lower limit of the standard tire pressure for car tires is sufficient. For example, the lower limit for standard tires is 2.4 bar. If the car is often parked outdoors, the tire pressure can generally be about 0.1 bar lower than the standard to prevent tire blowouts due to high temperatures. Hazards of Overinflated Tires: The friction and adhesion of the tires will decrease, affecting braking performance; it can cause steering wheel vibration and deviation, reducing driving comfort; it accelerates localized wear on the central tread pattern, shortening tire lifespan; increased body vibration indirectly affects the lifespan of other components. The tire's resistance to punctures decreases. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, and impacts can cause internal cracks and explosions, leading to blowouts. Hazards of Underinflated Tires: The friction coefficient with the road surface increases, leading to higher fuel consumption; it makes the steering wheel heavy and prone to deviation, which are factors detrimental to driving safety; it increases the movement of various parts of the tire, causing abnormal heat due to excessive rolling; it reduces the functionality of the cords and rubber, leading to delamination or cord breakage, and excessive friction with the rim can cause damage to the bead area and abnormal wear.

What does the yellow engine fault light mean?

There are generally two situations when the engine fault light comes on. The first situation is the self-check when the car is powered on, not only does the engine fault light come on, but other fault lights also come on, and they will turn off after a few seconds, which is a normal phenomenon. The second situation is when the fault light stays on constantly, which is the ECU alerting that there is a fault in the engine. Here are the solutions: Can continue driving: After the engine fault light comes on, if the car can still continue to drive and there are no abnormalities, this may be due to a fault in one of the engine's sensors or an error in the ECU system. For safety reasons, it is best to drive at low speed or stop and have it checked and repaired at a nearby repair shop. Cannot continue driving: After the engine fault light comes on, if the car cannot continue to drive or even cannot start, this situation is caused by a fault in the fuel pump or ignition system, and the only option is to call for a tow truck.

Should the Handbrake Be Engaged When in Park?

Automatic transmission models have gear positions P, R, N, and D. There is a difference between P and N gears. The P gear uses a mechanical lock to secure the rotating lock on the transmission, while the N gear allows free movement. Some vehicle models cannot remove the key when the gear is in N. Normally, the gear should be in P with the handbrake engaged to ensure the vehicle does not roll on a slope even if the handbrake is not applied. The functions and roles of the transmission gears are as follows: N: The N gear is neutral, disconnecting the transmission from the engine. R: Reverse gear, generally utilizing the reverse output function of the planetary gear set. D: Drive gear, connecting the engine power. P: The P gear is also neutral. When in P, the transmission executes the parking command, engaging the parking pawl and parking gear to lock the car using gear meshing resistance.

What is the working principle of a motorcycle transmission?

The working principle of the transmission is that when the gear shift pedal assembly is stepped on, the shift shaft rotates accordingly, causing the shift arm body S welded to the shift shaft to swing. The shift arm is connected to the shift arm body via a pin and is always pulled upward by a tension spring. Since the other end of the shift arm has a slot, and two positioning pins are located within this slot, the shift arm always presses against the positioning pins under the action of the tension spring. Under the influence of the slot hook, it pulls or pushes the positioning pins to move along the direction of the shift arm's motion. The function of the transmission: During motorcycle operation, as road conditions continuously change, it is necessary to frequently adjust the vehicle's speed and traction accordingly. For example, when driving on flat roads, the vehicle can travel faster, whereas on uneven roads or slopes, due to higher driving resistance, the speed must be reduced to increase the vehicle's traction. The structure of the transmission: Main shaft, secondary shaft, each with six gears of varying sizes, shift forks, and a shift drum.

What is the speed limit on urban single yellow line roads?

Urban single yellow line roads have a speed limit of 40 mph. Generally, urban speed limits range from 30 to 60 kilometers per hour, but this may vary in some cities. When driving in an unfamiliar city, drivers must slow down and pay attention to speed limit signs to avoid being caught by speed cameras for speeding. Urban roads are divided into ordinary urban roads and urban expressways. Ordinary urban roads typically have speed limits ranging from 30 to 60 kilometers per hour, while expressways may have a maximum speed limit of 80 kilometers per hour. Drivers should always refer to the posted speed limit signs for specific regulations. Below are speed limits for other types of roads: Roads without a center line: Urban roads: 30 kilometers per hour. Roads with only one lane in the same direction: Urban roads: 50 kilometers per hour. Roads with two lanes in the same direction: Maximum speed is 70 km/h, and enclosed motor vehicle lanes have a speed limit of 80 km/h.

What does insufficient exhaust flow mean?

Insufficient exhaust flow means that when the engine is idling, the amount of air-fuel mixture is very small. The exhaust gas entering the intake pipe dilutes the concentration of the mixture, which significantly affects the engine's idle operation, making the engine idle extremely unstable or even causing it to stall. One-way valve or gasket damage: This is likely due to a damaged one-way valve or gasket inside the exhaust valve that needs to be replaced. P0401 indicates that insufficient flow was detected in Exhaust Gas Recirculation (EGR) Valve A. The function of the EGR system is to introduce a small amount of exhaust gas into the intake manifold when the engine is operating under high load. The presence of these exhaust gases reduces the temperature and pressure in the combustion chamber, thereby decreasing the emission of nitrogen oxide pollutants. Exhaust Gas Recirculation (EGR) system malfunction: When the vehicle is operating normally and stably, and the EGR system is open, if the Electronic Control Unit (ECU) detects that the EGR flow rate is lower than the estimated value based on other information, this fault code will appear.
