What Causes Abnormal Noise When Braking a Car?

What is the normal temperature range for a car?

Here are the normal temperature ranges for a car engine: The normal operating temperature of a car engine is generally between 80°C and 90°C, while some high-performance engines can operate at temperatures above 90°C to 100°C. Below is relevant information about car engine temperature: 1. When the temperature is too high: When the engine temperature is excessively high, the intake air temperature also rises, resulting in reduced actual air intake. This decreases the engine's volumetric efficiency, leading to reduced power and torque output, manifesting as insufficient engine power. 2. When the temperature is too low: If the temperature of the air-fuel mixture (or air) entering the cylinders is too low, the combustible mixture quality deteriorates, making ignition difficult or causing delayed combustion. This results in decreased engine power, increased fuel consumption, and significantly higher emissions of harmful gases.

What are the dimensions of various parking spaces?

Parking space standard dimensions are mainly divided into two sizes: large and small. 1. Large parking spaces are 15.6 meters long and 3.25 meters wide, suitable for medium and large vehicles; 2. Small parking spaces are 6 meters long and 2.5 meters wide, suitable for small vehicles. Here is additional information: 1. Parking space arrangements can be categorized into parallel, angled (30°, 45°, 60°), and perpendicular. Large vehicle parking spaces should not use angled or perpendicular arrangements. 2. According to the "Urban Road Parking Space Setting Standards", roads with a width of less than 6 meters for motor vehicle traffic shall not have roadside parking spaces, and no parking spaces will be allowed on crosswalks or main roads of expressways.

What does ESC mean?

ESC is the term used by General Motors for the Electronic Stability Control system. More information about ESC is as follows: 1. ESC is an active safety technology that assists drivers in controlling the vehicle, and it is also an extension of the functions of the Anti-lock Braking System (ABS) and Traction Control System (TCS). On this basis, it adds a yaw rate sensor, lateral acceleration sensor, and steering wheel angle sensor when the vehicle is steering. 2. ESC mainly controls the longitudinal and lateral stability of the vehicle to ensure stable driving. When the vehicle understeers or oversteers, the system will control one or more wheels to brake, adjusting the vehicle's body posture during lane changes or cornering, making the car more stable when changing lanes or turning.

Is It Normal for a New Car's Engine to Be Noisy?

It is not normal for a new car's engine to be noisy. Here are some related explanations about a noisy engine in a new car: 1. Oil strainer issue: Poor sealing of the rubber ring prevents the oil pump from properly drawing oil and instead sucks in a large amount of air, leading to insufficient lubrication in the engine system, especially in the hydraulic valve lifters, resulting in metallic knocking sounds; a clogged oil strainer prevents proper oil intake into the engine lubrication system, causing poor lubrication. 2. Damaged hydraulic valve lifters: Long-term abnormal operation of the related system leads to insufficient lubrication of components, causing damage to the hydraulic valve lifters. The oil pump does not function properly and fails to draw in oil.

What is the main function of a clutch?

The clutch has the following four functions, described as follows: 1. Facilitate vehicle starting: The clutch primarily controls the vehicle's starting process, playing a more direct role in this aspect. 2. Enable gear shifting: In manual transmission vehicles, the clutch is crucial for gear shifting, as this process cannot be completed without it. 3. Prevent damage from excessive pressure in the transmission system: During power transmission, the clutch effectively controls the system's pressure. 4. Reduce torsional vibration impact: The clutch can efficiently manage the impact of torsional vibrations.

What Causes Car Shaking When Starting Up?

Reasons for car shaking during startup include loose or severely worn components, warped, tilted, or deformed driven plates, poor clutch lining contact, weakened damping spring elasticity, clutch judder, and uneven pressure distribution between the driving and driven plates. Causes of car shaking when starting up: 1. Loose or severely worn components: Clutch control mechanism being locked or having loose connections, severe wear on the clutch spline hub, or a bent transmission shaft can cause clutch judder. Solution: Replace the corresponding parts. 2. Warped, tilted, or deformed driven plates: When the driven plate is warped, tilted, or deformed, the clutch lining will have irregular contact during engagement, preventing smooth pressure increase. Solution: Correct or replace the driven plate. 3. Poor clutch lining contact: Poor contact, surface hardening, or adhesive residue on the clutch lining can easily cause clutch judder. Solution: Reattach the clutch lining. 4. Weakened damping spring elasticity: Reduced elasticity of the clutch torsional damping spring, weakened clutch pressure spring elasticity, or cracks in the diaphragm spring can all cause shaking during clutch engagement. Solution: Replace the springs. 5. Clutch judder: Let the engine idle, engage a low gear, slowly release the clutch pedal, and accelerate to start. If the car shakes, it indicates clutch judder. Solution: Replace the damaged parts among the clutch three-piece set (flywheel, clutch plate, pressure plate). 6. Uneven pressure distribution between driving and driven plates: Inconsistent elasticity of the clutch pressure springs, uneven adjustment of the release levers, or uneven diaphragm spring release finger ends can cause asynchronous pressure application, uneven force on the pressure plate, or even tilting, leading to poor contact between the driving and driven plates and clutch judder. Solution: Replace the clutch pressure springs and level the release levers.
