Honda Accord's lack of power during acceleration is mainly due to insufficient fuel supply to the engine. Using a diagnostic tool to inspect the PGM-Fl system and A/T system reveals no fault codes. The speed in both D and R positions is 2500r/min, which is normal. A time-lag test shows: D position at 1.1s and R position at 1.2s, with normal responses in all gears. Basic checks on the engine and automatic transmission also yield normal results. Additional relevant information is as follows: 1. Essential conditions for normal engine operation: Not only sufficient fuel supply but also adequate air. A clogged air filter or throttle system can lead to insufficient air intake. 2. Inspect the electrical system: Internal combustion engines require spark plugs to ignite the fuel entering the engine, so the condition of the spark plugs directly affects the ignition state. Spark plugs are consumables and need replacement after a fixed mileage.

How to Use Brakes on Icy Roads Without ABS Installed?

For vehicles not equipped with ABS when braking on icy or snowy roads, it is recommended to gently press the brake pedal or use intermittent braking to decelerate. This is because on icy, slippery, gravel, or other smooth surfaces, the wheels can easily lock up and cause loss of control. Avoid slamming on the brakes. Instead, first press the brake, then the clutch, and after releasing the clutch, intermittently apply the brakes while firmly holding the steering wheel to effectively reduce braking distance. Tips for driving on icy roads: 1. Reduce speed: Due to reduced friction between tires and the road, braking distance is significantly longer compared to dry surfaces. For example, stopping from 40km/h on ice requires the same distance as stopping from 70km/h on dry roads, and braking distance increases further with higher speeds. 2. Handling downhill and turns: On icy downhill sections, avoid coasting and instead reduce speed gradually without locking the brakes. Turns are particularly hazardous as the risk of skidding increases significantly. Always slow down before entering a curve, maintain a low speed throughout, and never attempt to overtake or change lanes in a curve. 3. Maintain straight-line driving: On icy roads, vehicles may struggle to stop or skid easily. Therefore, avoid frequent lane changes or overtaking and try to drive in a straight line as much as possible.

What problems will occur if the generator is broken?

If the car generator is broken, the following problems will occur: 1. The car lights or dashboard lights will become dim: The alternator is part of the vehicle's electrical system. Its main function is to provide power to operate the starter, ignition, and all electronic accessories in the car. If the generator is damaged, the car lights or dashboard lights will start to dim. Once the instrument lights or headlights become dim, this is a clear sign of potential alternator failure. 2. Damage to the battery or accumulator: A car battery, as a supplement to the generator, can only be charged to the point where it can accept the charge. If the battery is insufficiently charged or damaged, the car will continue to run, but after a short time, the lights will become dim again, indicating a problem with the charging system. If the vehicle has difficulty fully charging the battery after starting, this problem may be related to the alternator. 3. The car generator belt is a system belt that works in conjunction with the alternator. If the belt does not rotate freely, excess friction will cause the belt to heat up, producing a rubber burning smell. If you detect a smell similar to an electrical fire, this may indicate that the alternator pulley on the belt is slipping, resulting in poor generator output.

Where is the tire pressure displayed in the 2021 Sagitar?

The tire pressure data of the 2021 Sagitar is displayed on the instrument panel, as this model features an automatic tire pressure monitoring system. Additionally, if the tire pressure is insufficient or the tire is punctured or impacted, a tire pressure warning will appear on the dashboard. After troubleshooting, long-press the tire pressure monitoring button to clear the fault code. According to the international GBT2978-2008 standard, the normal tire pressure for different types of tires is as follows: Standard tires: 2.4-2.5bar; Reinforced tires: 2.8-2.9bar; Maximum pressure: Should not exceed 3.5bar. Hazards of overinflated tires: Reduced friction and adhesion, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates wear on the central tread pattern, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overstretches the tire cords, reducing elasticity and increasing the load on the vehicle during driving. Hazards of underinflated tires: Increased friction with the road surface, leading to higher fuel consumption; causes heavy steering and deviation, posing safety risks; increases movement of tire parts, leading to abnormal heat generation due to excessive rolling; reduces the functionality of cords and rubber, causing delamination or cord breakage and excessive friction with the rim, damaging the tire bead and causing abnormal wear; multiplies friction with the ground, sharply raising tire temperature, softening the tire, and drastically reducing strength. High-speed driving may lead to tire blowouts. If the tire pressure monitoring indicator light comes on (a yellow symbol with an irregular circle, no seal on top, four small spikes at the bottom, and an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure: Typically alerts when pressure is below 1.8bar or above 3.0bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the system will still record the previous data, causing the indicator light to remain on. Simply reset the tire pressure to resolve this. Damaged tire pressure sensor: The sensor, installed inside the tire and connected to the inflation valve, monitors tire pressure. If the sensor is damaged during driving, the tire pressure warning light will illuminate. For sensor damage, replacement with a new part is the only solution.

Can you still drive on highways without ETC in 2020?

It is possible to drive on highways without ETC. According to the "Notice on Vigorously Promoting the Development and Application of ETC on Highways" issued by the State Council, vehicles without ETC in 2020 will not enjoy toll discounts. In the future, only one manual lane will remain at highway toll stations, and tolls must be paid manually. Additionally, newly installed ETC devices cannot be used immediately on highways; they must be activated first. During free holiday periods, highways can still be used. For users who have already installed ETC, passing through ETC lanes will not incur charges. ETC toll deduction principle: Highways will have one or more ETC lanes. Through dedicated short-range microwave communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, and using computer networking technology for backend settlement with banks, the system achieves the goal of vehicles not needing to stop at toll stations to pay bridge and road fees. All of this is based on the principle of passing first and deducting fees later. Benefits of installing ETC: Save time: Eliminates the hassle of waiting in line; Green and eco-friendly: Low-carbon, as vehicles pass toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution; Reduce wear and tear: Saves costs by decreasing the frequency of vehicle starts and brakes, lowering wear and fuel consumption; Improve efficiency: ETC lanes can theoretically increase vehicle passing efficiency by 2-3 times, making traditional ETC more updated, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council explicitly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, intercity transportation cards will be interoperable in key city clusters, and the proportion of vehicles equipped with ETC will significantly increase." It also set a target in the "13th Five-Year" comprehensive transportation development indicators: "By 2020, the ETC usage rate for road passenger vehicles will reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and increasing the ETC usage rate for passenger vehicles, the future will also promote ETC usage for trucks and explore deep integration between the ETC system and smart transportation directions such as vehicle-to-vehicle communication and vehicle-road coordination. This will provide car owners with comprehensive travel services, meaning more application scenarios will support ETC applications.
