Toyota Avalon is equipped with three types of engines, with model numbers M20A/M20E, A25A/A25G, and A25B. The M20A/M20E engine has a maximum horsepower of 178 hp, a maximum power of 131 kW, a maximum power speed of 6600 rpm, and a peak torque of 210 N·m. The A25A/A25G engine has a maximum horsepower of 209 hp, a maximum power of 154 kW, a maximum power speed of 6600 rpm, and a peak torque of 250 N·m. The A25B engine has a maximum horsepower of 178 hp, a maximum power of 131 kW, a maximum power speed of 5700 rpm, and a peak torque of 221 N·m. The engines of the Toyota Avalon are manufactured in China. For daily maintenance of the Toyota Avalon's engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices in the intake and exhaust systems and usage conditions; for diesel engines, CB_CD grade diesel engine oil should be selected based on mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, causing various problems for the engine. To avoid failures, change the oil regularly according to usage conditions and maintain an appropriate oil level. When oil passes through the fine holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and oil cannot pass through, the filter may burst or the safety valve may open, allowing oil to bypass the filter and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal pollution. 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 powder 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. Regularly use radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.

What is the Brake Pedal of a Motor Vehicle?

Here is the relevant introduction to the brake pedal of a motor vehicle: 1. As the name suggests, the brake pedal is a pedal that restricts power, specifically the pedal for the foot brake (service brake), used for decelerating and stopping. The brake pedal, also known as the "foot brake pedal," is generally operated by the right foot. It is located at the bottom of the driver's compartment, to the left of the accelerator pedal, and serves as the control device for the service brake. 2. It is one of the five major control components in vehicle operation, with a very high frequency of use. How the driver handles it directly affects driving safety. There is a small pedal connected to the brake lever above the brake, hence this pedal is also referred to as the "brake pedal." The clutch also has a small pedal, known as the clutch pedal. The clutch is on the left, and the brake is on the right (aligned with the accelerator, with the accelerator on the right).

How to Check Blind Spots While Driving?

Methods for observing different blind spots while driving are as follows: 1. Rear Blind Spot: Before getting into the car, thoroughly inspect the surroundings to ensure safety. Pay special attention to the rear of the vehicle. If someone is crouching behind the car and the vehicle lacks a panoramic camera, it can be difficult to detect, posing significant safety risks if driving commences without proper checks. 2. Left A-Pillar Blind Spot: This blind spot is hard to avoid while driving. To enhance safety, it's advisable to choose a vehicle with a relatively small left A-pillar blind spot when purchasing a car. During driving, to prevent accidents caused by this blind spot, avoid prolonged driving in the far-left lane on wide roads. If driving on the left is unavoidable, adjust speed appropriately and be prepared to brake. 3. Right A-Pillar Blind Spot: When turning, signal in advance and observe the right-side road conditions. If traffic rules permit, use the horn to alert passing vehicles. Reduce speed during turns and be ready to brake immediately. Whenever possible, avoid stopping on the right side of large vehicles.

What Causes the Abnormal Noise When Turning the Steering Wheel of a Compass While Stationary?

When the Compass makes abnormal noises while turning the steering wheel in place, it is due to a malfunction in the vehicle's steering system. The source of the malfunction varies, leading to different types of noises, which require a step-by-step inspection. The specific reasons are as follows: Noise from the steering column dust cover: Whether the car is in motion or turning the steering wheel while stationary, this sound can be heard coming from below the steering wheel. In such cases, the steering column dust cover needs to be inspected. If the steering column dust cover lacks lubrication, it will produce a dry friction sound. Simply applying some grease to this area will eliminate the abnormal noise. Noise caused by interference from the clockspring: When the car turns the steering wheel while stationary, the sound comes from inside the steering wheel. This issue is mostly caused by interference from the clockspring inside the steering wheel, often due to damage to the clockspring, which requires timely replacement.

What is the original tire of the Compass?

The original tires of the Compass are Continental tires, specifically 25/60R17 and 225/5R18, with CPC2 tread pattern, load index 96, and speed rating H. Below are the relevant details: Precautions for using tires: Regularly correct wheel balance. Excessive wheel imbalance will cause high-frequency vibrations at high speeds, leading to uneven tire wear and compromising driving safety. After tire repair, dynamic balance testing and adjustment should be performed. The single-side dynamic balance test value should be ≤40 grams. Regularly rotate tires. To ensure even tire wear on the same vehicle, tires should be rotated every 5,000 km, and a four-wheel alignment should be performed every 5,000-10,000 km to avoid abnormal excessive wear. Do not install tires of different models or with significant differences in wear on the same axle. Advantages of Continental tires: Continental tires are known for their safety, reliability, and low noise levels. The unique tread design on the tire surface enhances vehicle handling performance. Additionally, Continental tires offer excellent braking performance on both dry and wet surfaces, as well as superior water drainage protection.

What is the Essence of Braking?

The essence of braking is the forced conversion of a vehicle's kinetic energy into other forms of energy (typically thermal energy), which is then dissipated into the surrounding atmosphere. Below are the relevant details: Precautions for vehicle braking: When driving at high speeds, it is crucial to identify potential hazards early, release the accelerator pedal promptly, and utilize engine braking to reduce speed. When the brake pedal must be applied, use "pump braking" (press and release, then press again) to gradually decelerate the vehicle. This causes the brake lights to flash multiple times as the pedal is pressed and released, making it easier for following vehicles to notice and helping to prevent skidding. Functions of braking: To forcibly decelerate or even stop a moving vehicle as required by the driver; to keep a stationary vehicle stable under various road conditions (including on slopes); and to maintain a stable speed for vehicles descending slopes. Only external forces acting on the vehicle and opposing its direction of motion can provide braking effects. However, the magnitude of these forces is random and uncontrollable, necessitating the installation of specialized systems in vehicles to achieve the aforementioned functions.
