What suspension does the Accord use?

The Accord features a MacPherson strut independent front suspension and a multi-link independent rear suspension, which is a common suspension configuration. The primary difference between the MacPherson strut and multi-link suspensions lies in their structure. The MacPherson strut is the most cost-effective and widely applicable, while the multi-link suspension is capable of high-performance tuning and matching. However, due to structural and manufacturing complexities, the multi-link suspension is significantly more expensive than the MacPherson strut. MacPherson Strut Suspension: The MacPherson strut suspension consists of a coil spring, shock absorber, and triangular lower control arm. Most models also include a stabilizer bar. The main structure involves the coil spring being mounted over the shock absorber. The shock absorber prevents the coil spring from shifting forward, backward, left, or right under force, restricting the spring to vertical vibrations only. The suspension's stiffness and performance can be adjusted by altering the shock absorber's travel length and tightness. Multi-Link Independent Suspension: This can be divided into multi-link front suspension and multi-link rear suspension systems. The front suspension typically uses a 3-link or 4-link independent suspension, while the rear suspension usually employs a 4-link or 5-link system, with the 5-link rear suspension being more widely used.

What Causes a New Car to Sometimes Fail to Start and Sometimes Start Normally?

Reasons why a new car fails to start are as follows: 1. The steering wheel is in a locked position: Many people encounter situations where the car won't start, and the key can't be turned. In such cases, it's important to note that if the steering wheel isn't straightened when parked and is at a slightly larger angle (over 30 degrees), the steering wheel will automatically lock as an anti-theft measure. This may prevent the key from turning, causing the ignition to fail. 2. The gear is not returned to P when parking: For automatic transmission vehicles (AT, CVT, AMT), ensure the gear is in the P position when starting. 3. Low battery in the smart key for one-button start: If the key is inside the car but the dashboard always shows "key matching error," it's likely due to a low battery in the smart key, preventing the start system from detecting the weak signal emitted by the key. 4. Dead battery: Failure to start may be caused by a drained battery due to reasons like leaving the headlights on for too long or the battery reaching the end of its lifespan. Generally, replace the battery in time according to the maintenance manual. 5. Empty fuel tank: If the fuel gauge shows below the red line, the car naturally won't start. Also, pay attention to the quality of the fuel.

What are the disadvantages of low gear and high speed?

The hazards of low gear and high speed: 1. Wastes gasoline. 2. Fails to fully utilize the car's kinetic energy, causing the engine to run at high speed while the gearbox operates in low gear. Suddenly shifting a high-speed car into low gear will make the car's operation drive the engine, resulting in changes in sound, which is not advisable during operation. 3. Long-term use can cause a large amount of carbon buildup. The hazards of low speed and high gear: 1. Driving at high gear and low speed makes it difficult to utilize the engine's full power and may even damage the vehicle's powertrain. 2. When the engine operates in high gear and low speed, the engine output is weak, with low torque. Even if you press the accelerator hard, it lacks the power to speed up. As a result, a lot of fuel is consumed, but the engine runs very slowly, so it is not fuel-efficient. 3. Running for a long time in high gear and low speed keeps the engine working near the critical speed, often on the verge of stalling. The insufficient output force prevents the transmission from functioning properly, causing significant damage to the transmission. 4. Low-speed operation makes it difficult to achieve the engine's self-cleaning effect, leading to carbon buildup in the engine and fuel system, which can eventually cause faults in the engine and fuel system.

How to Replace the Brake Pads on a LaCrosse?

First, enter the brake system maintenance mode, turn on the power, and press the handbrake three times continuously while holding down the brake pedal. Continue until the handbrake mode on the dashboard flashes. Then, use a piston press pump to push the piston to its maximum position, and finally install the new brake pads. Below are the detailed replacement steps: 1. First, enter the brake system maintenance mode, turn on the power, and press the handbrake three times continuously while holding down the brake pedal. Continue until the handbrake mode on the dashboard flashes. 2. Prepare the new brake pads for replacement and remove the wheel where the brake is located. Be careful to avoid scratching the rim during the removal process. 3. Use a wrench with a socket to remove the bolts of the brake caliper, then take out the old brake pads. Check if the brake pads are excessively worn or have cracks. If so, proceed with the replacement. 4. Since the brake caliper may have accumulated sand or dirt, clean it thoroughly with a cloth and apply anti-squeal paste to prevent noise during braking. 5. Use a piston press pump to push the piston to its maximum position, then install the new brake pads onto the caliper. Once the new brake pads are properly installed, tighten the guide bolts to complete the installation.

Should the oil filter be replaced when changing the engine oil?

When changing the engine oil, it is necessary to replace the oil filter as well. The oil filter is responsible for filtering out impurities from the engine oil. If not replaced, the oil will become dirty and lose its protective function for the engine. Its primary role is to remove contaminants, sludge, and moisture from the oil, delivering clean oil to all lubrication points. Engine oil inherently contains a certain amount of sludge, impurities, moisture, and additives. To reduce friction between moving parts in the engine and minimize wear, oil is continuously circulated to the friction surfaces of moving components, forming a lubricating film. Additionally, during engine operation, metal particles, airborne contaminants, and oxidation byproducts accumulate in the oil, gradually increasing the level of impurities.

How often should the spark plugs of Geely Emgrand be replaced?

Geely Emgrand spark plugs should be replaced every 3 years. The original equipment uses nickel alloy spark plugs, and double iridium spark plugs can be used as replacements. Spark plugs are a crucial component of the gasoline engine ignition system, responsible for introducing high voltage into the combustion chamber and generating sparks by jumping across the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. Geely Emgrand is a sub-brand under the parent brand Geely. Taking the 2019 Emgrand as an example, the car's body dimensions are 4632mm in length, 1789mm in width, 1470mm in height, with a wheelbase of 2650mm, positioning it as a compact car.
