What are the causes of idle noise in Honda 5AT transmission?

The cause of idle noise in Honda 5AT transmission may be bearing damage. Reasons for transmission idle noise: Excessive deviation in the perpendicularity between the front face of the transmission housing and the concentric line of the first and second shafts, or excessive coaxiality deviation between the first/second shafts and the crankshaft. Damage to the front ball bearing of the first shaft. Damage to the rear ball bearing of the first shaft. Damage to the front bearing of the second shaft. Mismatched constant mesh gear pair. Constant mesh gears worn into a stepped shape or with damaged teeth. Changes in gear meshing conditions due to replacement of shafts or bearings. Diagnostic methods for transmission noise: With the engine idling and the transmission in neutral, if noise occurs and intensifies when the handbrake is engaged but disappears when the clutch pedal is depressed, and the noise is not noticeable during vehicle operation, it indicates wear and looseness in the rear ball bearing of the first shaft or its housing. If the transmission produces uneven noise that becomes louder when the handbrake is engaged and remains audible during driving, it often indicates poor meshing of the constant mesh gears. Excessive deviation in the parallelism of the transmission's three shafts or between the first/second shafts and the crankshaft can cause such noise, which intensifies when driving in non-direct gears. If the transmission exhibits obvious noise during engine idle that increases with RPM and turns into gear impact sounds, gently push/pull the gearshift lever. If noticeable vibration is felt, slightly loosen the transmission cover bolts and adjust its position. If noise disappears or reduces at certain positions, it indicates original misalignment of the transmission cover. If noise persists, inspect whether the shift fork fastening screws are loose or the fork is deformed, and further check for gear damage. When noise increases uniformly with engine RPM, it's often caused by changed gear meshing conditions after intermediate shaft bearing replacement.

What is the fuel consumption of the Binyue?

The comprehensive fuel consumption of the Binyue is 6.1-6.3L/100km. There are currently 6 models of the Binyue on sale: the manual Gold Edition with a comprehensive fuel consumption of 6.1L/100km, and the DCT Platinum Edition, DCT Diamond Edition, DCT-Battle, DCT Starlight Edition, and DCT Glory Edition, all with a comprehensive fuel consumption of 6.3L/100km. The above figures are the NEDC comprehensive fuel consumption, which is the fuel consumption data measured under the NEDC test procedure. The actual fuel consumption is higher than this value, ranging from 7.0-8.2L/100km. The level of a car's fuel consumption is directly related to five major factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. Specific factors that can increase a car's fuel consumption are as follows: Driving habits: Aggressive driving behaviors such as sudden acceleration, frequent overtaking, and not easing off the throttle in advance when approaching a red light can increase fuel consumption. The car itself: Cars with larger engine displacements generally consume more fuel than those with smaller displacements because larger displacements usually mean greater power, requiring more gasoline to burn and perform work. Cars with greater weight also consume more fuel because greater weight requires more driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases the car's resistance and fuel consumption. Low environmental temperatures: When the engine block temperature is low during cold starts, the injected gasoline is less likely to atomize, requiring more gasoline to be injected for combustion, thus increasing fuel consumption. Additionally, at low temperatures, the engine's computer will control the engine to run at higher RPMs to warm up, which also increases fuel consumption.

Is Euro 3 Equivalent to China 4 or China 3?

Euro III emission standards are approximately equivalent to China III emission standards. Below is more information about automotive emission standards: 1. Concept: Automotive emission standards refer to regulations on the content of harmful gases emitted from vehicle exhaust, such as CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), and PM (particulate matter, soot). 2. China III Emission Standards: The China III emission standards are equivalent to the Euro III emission standards, requiring HC emissions below 0.2g/km; CO emissions below 2.3g/km; and NOx emissions below 0.15g/km.

What is the Basic Principle of a Manual Transmission?

Manual transmission operates on the fundamental principle of utilizing gear sets with different tooth counts to achieve changes in rotational speed and torque. As a speed-changing device, it modifies the engine's rotational speed and torque transmitted to the drive wheels, enabling the vehicle to obtain varying traction and speed during stationary starts, hill climbing, turning, and acceleration, while keeping the engine operating within a more favorable range. The functions of a manual transmission include: 1. Altering the gear ratio to expand the range of torque and speed variations at the drive wheels; 2. Enabling reverse vehicle movement by utilizing the reverse gear while maintaining the engine's rotational direction.

What is the double white dashed line at an intersection?

Intersection double white dashed lines are yield lines. Below is relevant information about yield lines: 1. Function: Indicates that vehicles should slow down and yield, notifying drivers that they must slow down or stop, observe traffic conditions on the main road, and only proceed when it is safe to do so, ensuring priority for vehicles on the main road. 2. Regulation: At intersections marked with yield lines, vehicles must stop and yield to vehicles on the main road. These lines should be used in conjunction with a 'Yield' sign. Yield lines consist of two parallel dashed lines and an inverted triangle, all in white.

What are the steps to replace the battery in a car key?

Car key battery replacement steps are: 1. Slide the safety switch on the remote key; 2. Remove the mechanical key; 3. Insert the mechanical key into the gap at the bottom to pry open the shell; 4. Use a hard card to pry out the old battery from the battery gap and replace it with a new battery of the same model; 5. Reassemble the shell and reinsert the mechanical key. Key maintenance methods include: 1. Avoid frequently placing the key with metal objects; 2. Do not place the spare key in the car door; 3. Prevent the smart key from falling or being impacted; 4. Avoid exposing the smart key to high temperatures or contact with liquids; 5. Do not place the key with electronic devices.
