An automobile's crucial components consist of five fundamental parts: the engine, chassis, body, electrical equipment, and tires. Engine: The engine serves as the power plant of a vehicle, comprising two major mechanisms and five systems: the crank-connecting rod mechanism, valve train, cooling system, fuel supply system, lubrication system, ignition system, and starting system. However, diesel engines lack an ignition system compared to gasoline engines. Chassis: The chassis is composed of the transmission system, running gear, steering system, and braking system. The vehicle body is mounted on the chassis frame, designed for driver/passenger accommodation or cargo transportation. Passenger cars and buses typically feature unitary body construction, while trucks generally have separate cab and cargo box structures.

Why does the car still roll when in N gear?

Here are the specific reasons why the car rolls when in N gear: 1. Linkage mechanism misalignment: The gear shift linkage mechanism is misaligned and not fully engaged; this can be adjusted to resolve the issue. 2. Locking mechanism wear: The reverse gear locking mechanism inside the transmission is worn and cannot effectively lock the reverse gear. 3. Long-term wear: The inertial lock ring and the internal meshing teeth on the sliding sleeve wear over time, forming a conical shape, which generates axial thrust on the meshing teeth. When this thrust exceeds the spring lock force of the gear, disengagement occurs. 4. Softened lock force: The spring lock force of the gear softens or breaks, or the self-locking steel ball comes out or is damaged. 5. Improper adjustment: The gear shift mechanism in the operating lever is improperly adjusted, causing incomplete gear engagement and leaving the meshing teeth in a semi-engaged state.

What Causes the Brake Light to Stay On?

Here are the specific reasons why the brake light stays on: 1. Faulty brake switch: This usually occurs when the brake pedal does not make proper contact with the brake sensor switch or the sensor switch is damaged. 2. Worn or aged brake pads: Worn or aged brake pads can also cause the brake light to stay on. It is necessary to check the thickness of the brake pads. If the thickness is below the specified value, typically 0.8 cm, there is a high risk of the pads cracking during driving, which can be dangerous. 3. Low brake fluid: Brake fluid plays a crucial role in the vehicle's braking system. When the brake pedal is pressed, the force applied is transmitted through the master cylinder piston and the brake fluid to the wheel cylinders, causing the brake pads to contact the wheels and stop the vehicle. Low brake fluid can also lead to noticeably reduced braking power and, in severe cases, a complete loss of braking. This issue can be resolved by promptly replenishing the brake fluid. Low brake fluid causes the brake pedal to sink, keeping the brake switch continuously powered, which results in the brake light staying on.

Will Putting 200 Pounds in the Trunk Damage the Car?

In theory, loading 200 pounds of items into a sedan's trunk is not a problem. Even carrying 500 pounds is structurally feasible for a car. However, it should be noted that while there is no explicit standard for the loading capacity of sedans, it is generally recommended not to exceed 300 pounds. Here are some issues related to excessive trunk loading weight: 1. Risk of Tire Blowout: Excessive loading weight increases the burden on the tires. If the tires remain under high pressure for a prolonged period, it can lead to a blowout, especially during the hot summer months when the risk is even higher. 2. Impact on Steering Function: Generally, the front wheels of a vehicle have a steering function. If the trunk carries too much weight, and considering that the rear wheels do not have a steering function, the steering capability of the front wheels can be compromised. This situation becomes more severe on highways and may even lead to traffic accidents. Additionally, an overloaded trunk can increase the vehicle's braking distance, naturally reducing driving safety.
