Does Earth Dreams Engine Have Less Carbon Deposits with 95 or 92 Octane?

There is no difference. Whether using 95 or 92 octane gasoline in Earth Dreams engines, it has no relation to carbon deposits inside the engine. Different gasoline octane ratings represent different octane values, primarily affecting the fuel's anti-knock properties. Gasoline Octane Rating: The octane rating indicates the gasoline's anti-knock performance and has absolutely no connection with cleanliness or delaying carbon deposit formation. However, using the wrong engine oil can indeed affect the vehicle. In reality, all gasoline-powered vehicles will inevitably face carbon deposit issues—it's just a matter of sooner or later, more or less. Direct Injection Technology: Honda's Earth Dreams series engines employ direct injection technology, which inherently tends to cause carbon buildup on fuel injectors and intake valves. Currently, there is no effective solution, making the maintenance and upkeep costs of direct injection engines relatively higher. From a usage perspective, as long as you use high-octane fuel normally and change the engine oil regularly (preferably using full synthetic oil), carbon deposits won't affect normal operation.

Who is Responsible for Water-Damaged Cars in Underground Garages?

Insurance companies should be responsible for compensating the losses of insured motor vehicles caused by natural disasters according to the agreement. Damage to cars due to flooding in underground garages falls under the coverage conditions of auto damage insurance. Since parking fees have been paid to the property management company, a legal relationship of paid custody has been established with them. The hazards of water-damaged cars are as follows: Damage to electronic control systems: It can harm the internal electronic control systems of the car. The mixed rainwater is highly corrosive, affecting the functionality of electronic components, especially future usage. Most cars are equipped with electronic control systems (e.g., engine ECU, ABS system, SRS system, GPS navigation, etc.), and water exposure can cause short circuits in the ECU's internal IC circuit boards and rust on connector terminals. Circuit short circuits: This gradually leads to rust on metal parts, causing poor contact in circuits, and even short circuits or burnout. After a car is water-damaged, never attempt to start or turn the engine, as this can severely deform the engine connecting rods. Moreover, forcibly starting the engine often results in the insurance company refusing to compensate.

What does a light bulb with a cross represent as a fault?

Light bulb with a cross represents the bulb failure warning light. Here are the reasons why the bulb failure light comes on: 1. Self-check process: During the ignition switch activation, the indicator light will illuminate for a few seconds as the vehicle computer performs a self-check, then turn off completely. If it doesn't light up during this process, it may indicate an open circuit in the instrument cluster, requiring immediate repair to avoid affecting fault indication. 2. Indicator lights: Various warning or indicator lights are installed beneath the instrument cluster's faceplate, such as coolant level warning light, fuel level indicator, washer fluid level indicator, charging indicator, etc. Therefore, the instrument cluster serves as a device reflecting the working status of various vehicle systems. Common ones include fuel indicator, washer fluid indicator, electronic throttle indicator, front/rear fog light indicators, and warning lights.

What is the reason for the car not being able to shift gears the day after driving through water?

The reasons why a car cannot shift gears the day after driving through water are as follows: 1. Air filter: The air filter is the gateway for air to enter the engine. After the vehicle has driven through water, check the air filter and intake pipes. If they are wet, it indicates that water may have entered the engine, and a thorough inspection of the engine's internal water ingress is required. 2. Engine compartment wiring harness: There are numerous wiring harnesses and circuits in the engine compartment. Driving through water can easily wet the connectors of the wiring harnesses. If the connectors are found to be wet during inspection, they need to be dried immediately. If not treated promptly, it may lead to a short circuit. 3. Chassis malfunction: When driving through water, dirt can accumulate in the gaps of the chassis and other areas, leading to rust and even component failure. Therefore, after driving through water, the owner should take the vehicle to a car wash for a thorough cleaning of the chassis. Applying a chassis armor can also enhance the chassis's rust resistance.

Is it easier to climb a slope with the air conditioning on during hill start?

Starting on a slope with the air conditioning on makes it harder to climb. Here is an introduction to hill start knowledge: 1. Test subject: Hill start is part of the field test in driving license exam (Subject 2), which involves starting a vehicle parked on a steep slope. When learning the technique of hill start for manual transmission vehicles, the steps are: first pull the handbrake, press the accelerator to at least 2000 RPM, then release the clutch until it drops to around 1000 RPM, release the handbrake, slightly release the clutch while adding a bit more gas, and the car will naturally climb the slope. 2. Precautions: The sequence of starting operations should be standardized and correct, with actions performed in order or simultaneously, without omission; during the start, maintain the correct driving posture, keep eyes on the road ahead, and avoid looking down.

Is the Transmission Oil the Same as the Rear Axle Oil?

Transmission oil and rear axle oil are different. When replacing transmission oil, it is necessary to use dedicated transmission oil and not substitute it with other fluids. Transmission oil is crucial for the transmission system as it serves functions such as power transmission, heat dissipation, lubrication, and rust prevention. More details are as follows: 1. There are two types of car transmissions: automatic transmissions and manual transmissions. 2. There are three common types of automatic transmissions in cars: AT transmissions, dual-clutch transmissions, and CVT transmissions. 3. Dual-clutch transmission: This is a product developed based on manual transmissions. Its structure is similar to that of a manual transmission, with the addition of an extra clutch and a set of gear-shifting control mechanisms. One clutch controls the odd-numbered gears, while the other controls the even-numbered gears. Dual-clutch transmissions offer fast gear-shifting speeds and relatively high transmission efficiency. 4. CVT transmission: This is a relatively simple automatic transmission with only two cone wheels and a steel belt inside. The steel belt can move on the cone wheels, allowing the transmission to change speed and torque. CVT transmissions are compact, lightweight, and relatively low-cost.
