What is the fuel consumption of the Toyota Reiz?

Toyota Reiz has a total of 7 models on sale, including the 2021 2.0L CVT Front-Wheel Drive Urban Edition, 2021 2.0L CVT Front-Wheel Drive Fashion Edition, and other 7 models equipped with a 193 horsepower engine, with an NEDC fuel consumption of 9L per 100 kilometers. The fuel tank capacity of different Reiz models varies, and the distance that can be covered with a full tank of fuel is as follows: Models equipped with a 193 horsepower engine have a fuel tank capacity of 70L, and the distance that can be covered with a full tank of fuel is 70/9*100=778KM. 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, such as sudden acceleration, frequent overtaking, and not easing off the throttle before reaching a red light, can increase fuel consumption. The car itself: Cars with larger displacement generally consume more fuel than those with smaller displacement because larger displacement usually means greater power, requiring more gasoline to burn and perform work. Cars with greater weight also have higher fuel consumption 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 temperature: When the engine block temperature is low during a cold start, the injected gasoline is less likely to vaporize, requiring more gasoline to be injected for combustion, thus increasing fuel consumption. Additionally, at low temperatures, the engine's computer may control the engine to run at higher RPMs to warm up, which also increases fuel consumption.

What are the engine specifications of the Jeep Cherokee?

The Jeep Cherokee is equipped with engine model 46338538, delivering a maximum horsepower of 265 HP and a maximum power output of 195 KW at 5200 rpm, with a peak torque of 400 Nm. The Cherokee's engine is jointly produced by GAC and Fiat Chrysler, assembled domestically in China with technical support from abroad. For daily maintenance of the Cherokee's engine, the following methods are recommended: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, ensuring the standard meets or exceeds the manufacturer's requirements. Regularly change the oil and filter. The quality of any lubricating oil deteriorates over time. After a certain mileage, degraded oil can cause various engine issues. To prevent malfunctions, change the oil periodically according to usage conditions and maintain an appropriate oil level. As oil passes through the fine pores of the filter, solid particles and viscous substances accumulate in the filter. If the filter becomes clogged and oil cannot pass through, it may rupture the filter or open the safety valve, bypassing the filter and carrying contaminants back to the lubrication points, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. Small amounts remain suspended in the oil, while larger amounts precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear. Periodically use a radiator cleaner to flush the radiator. Removing rust and scale deposits not only ensures proper engine operation but also extends the overall lifespan of the radiator and engine.

What is the actual fuel consumption of the Peugeot 508?

Peugeot 508's combined fuel consumption is 6-6.1L/100km. There are currently 5 models of the Peugeot 508 on sale: the Pioneer Edition and the Drive Fun Edition, with a combined fuel consumption of 6L/100km. The Sport Edition, Passion Edition, and Drive Control Edition have a combined fuel consumption of 6.1L/100km. The above figures are the NEDC combined fuel consumption, which is the fuel consumption data measured under the NEDC test cycle. The actual fuel consumption is higher than this value, ranging from 8.0-8.8L/100km. Automobile fuel consumption is directly related to five major factors: driving habits, the vehicle itself, road conditions, natural wind, and environmental temperature. Specific factors that increase fuel consumption are as follows: Driving habits: Aggressive driving, such as sudden acceleration, frequent overtaking, and not easing off the throttle before encountering a red light, will increase fuel consumption. The vehicle itself: Vehicles 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. Heavier vehicles 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 vehicle resistance and fuel consumption. Low environmental temperatures: When the engine block temperature is low, the gasoline injected during cold starts does not atomize easily, requiring more gasoline to burn, which increases 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.

What Causes Steering Wheel Vibration When Braking While Driving?

Introduction to the causes of steering wheel vibration when braking while driving: 1. Tire deformation: Lift the front axle and rotate the wheels to check the static balance of the wheels and whether the tire or wheel hub is excessively deformed. If deformation is found, replacement is necessary. Steering wheel vibration typically occurs at speeds between 80 km/h and 90 km/h and returns to normal when exceeding 90 km/h. This is mostly caused by tire deformation or issues in the vehicle's drivetrain. 2. Incorrect tire dynamic balance: If the tire dynamic balance values are inaccurate, the steering wheel may vibrate within a certain speed range. Wheel dynamic balance needs to be recalibrated. Check if the front wheel alignment angles and toe-in meet requirements; adjust if necessary. 3. Drivetrain malfunction: Issues in the vehicle's drivetrain can cause this problem. Check if the front wheel alignment angles meet requirements and adjust if necessary. 4. Worn or loose half-shaft/tie rod ball joints or detached rubber bushings at joints: Replace damaged components. The vehicle may drive normally on flat roads but exhibit steering wheel vibration on bumpy roads. This is due to worn or loose tie rod ball joints, detached rubber bushings, or irregular tire wear. Professional inspection and replacement of damaged parts are required. 5. Twisted or deformed drive shaft, or loose, dry, or rusted universal joints: These components are located under the vehicle and are often overlooked during maintenance. Ensure that maintenance personnel apply grease to lubricatable areas during each service. 6. Warped brake discs: This issue mainly manifests as steering wheel vibration during high-speed braking. The brake discs may need replacement or resurfacing. Sudden braking at high speeds can cause steering wheel vibration. Excessive or frequent braking may overheat the brake discs and pads, leading to deformation when cooled. Symptoms usually resolve after replacing the brake discs and pads. 7. Overly loose or tight power steering belt: Primarily affects vehicles with mechanical hydraulic power steering. This issue can cause significant steering wheel vibration when turning. Adjust the belt tension or replace the belt as needed.

What is the normal tire pressure for Honda City?

The normal tire pressure range for the Honda City is 2.4-2.5 bar. Due to seasonal factors, the tire pressure can be increased by 0.2 bar in winter and reduced by 0.1 bar in summer. This data is based on the international GBT2978-2008 standard. The Honda City is not equipped with a tire pressure monitoring system or a tire pressure warning light, so it is necessary to regularly check the tire pressure to avoid safety issues while driving. Generally, a tire pressure above 2.8 bar is considered too high, and a tire pressure below 2.0 bar is considered too low. Hazards of overinflated tires: Reduced tire friction and adhesion, affecting braking performance; causing steering wheel vibration and deviation, reducing driving comfort; accelerating wear on the central tread of the tire, reducing tire lifespan; increasing vehicle vibration, indirectly affecting the lifespan of other components; excessive stretching of tire cords, reducing tire elasticity, and increasing the load on the vehicle while driving. Hazards of underinflated tires: Increased friction coefficient with the road surface, leading to higher fuel consumption; causing heavy steering and deviation, posing risks to driving safety; increasing movement of tire parts, leading to abnormal heat generation due to excessive rolling; reducing the functionality of cords and rubber, causing delamination or cord breakage, and excessive friction with the rim, damaging the tire bead area and causing abnormal wear; exponentially increasing friction between the tire and the ground, rapidly 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 below, and an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure: Usually, it will alert if the pressure is below 1.8 bar or above 3.0 bar. 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 tire pressure monitoring light to come on. Simply reset the tire pressure. Damaged tire pressure sensor: The tire pressure sensor, used to monitor tire pressure, is installed inside the tire and connected to the tire inflation valve. If the sensor is damaged while driving, it will also trigger the tire pressure warning light. For sensor damage, the only solution is to replace it with a new one.

What is the tire size of the Teramont?

The Teramont has three tire size specifications: 265/45R21, 255/50R20, and 255/55R19. In 265/45R21, the first number 265 represents the tire width of 265MM, 45 indicates the aspect ratio of the tire section is 45%, meaning the section height is 45% of the width, 21 represents the rim diameter of 21 inches, and the middle letter "R" stands for radial tire. In 255/50R20, the first number 255 represents the tire width of 255MM, 50 indicates the aspect ratio of the tire section is 50%, meaning the section height is 50% of the width, 20 represents the rim diameter of 20 inches, and the middle letter "R" stands for radial tire. In 255/55R19, the first number 255 represents the tire width of 255MM, 55 indicates the aspect ratio of the tire section is 55%, meaning the section height is 55% of the width, 19 represents the rim diameter of 19 inches, and the middle letter "R" stands for radial tire. If you want to replace the tires yourself, you can follow these steps: Take out the spare tire and jack, place the jack under the frame of the tire to be replaced, ensuring the jack touches the metal part of the frame; Raise the jack until it supports the car, the jack should be positioned under the vehicle, check and ensure the jack is at a right angle to the ground; Remove the hubcap, loosen the nuts counterclockwise, do not fully loosen them, just enough to eliminate resistance, keeping the tire on the ground when first loosening the nuts ensures the nuts turn rather than the tire; Turn the nuts counterclockwise until they come off, repeat this step for all lug nuts, completely remove the nuts; Place the new tire on the hub, carefully align the tire rim with the wheel bolts, install the lug nuts, hand-tighten the nuts until all nuts are concealed, at this point the tire replacement is complete. In addition to the model, the tire also has the following common data marked on it: Tire cord material: indicated by Chinese pinyin, such as M-cotton cord, R-rayon cord, N-nylon cord, G-steel cord, ZG-steel radial cord tire. Speed rating: indicates the maximum speed the tire can carry the specified load under specified conditions. Letters A to Z represent the certified speed ratings of tires from 4.8km/h to 300km/h. Common speed ratings include: Q: 160km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h; Rim specification: indicates the rim specification compatible with the tire. For practical use, such as "Standard rim 5.00F".
