What are the reasons for abnormal noise when stepping on the brake of a Mercedes-Benz C-Class?

What is the function of an engine cylinder head?

The function of an engine cylinder head is: 1. To seal the upper part of the cylinder and form the combustion chamber; 2. To serve as a support for the camshaft, rocker arm shaft, and intake/exhaust pipes; 3. To draw air into the cylinder interior, where the spark plug ignites the combustible gas mixture, driving the piston to perform work and expelling exhaust gases through the exhaust pipe. There are two common types of engine cylinder heads: 1. The side-valve engine cylinder head, which is cast with a water jacket, water inlet hole, water outlet hole, spark plug hole, bolt hole, and combustion chamber; 2. The overhead-valve engine cylinder head, which, in addition to the cooling water jacket, includes the valve mechanism, intake and exhaust passages. A common issue is improper valve clearance (too large or too small), leading to valve noise or failure of the camshaft position sensor on the cylinder head.

Antifreeze Indicator?

The indicator for insufficient car antifreeze is a small sailboat-like symbol on the dashboard. Introduction to Antifreeze: The full name of antifreeze should be antifreeze coolant, meaning a coolant with antifreeze properties. Antifreeze prevents the coolant from freezing in cold seasons, which could lead to radiator cracks and engine block freezing. A common misconception should be corrected: antifreeze is not only used in winter. In regular car maintenance, the engine antifreeze needs to be replaced annually during driving. Functions of Antifreeze: Antifreeze has multiple functions including antifreeze, anti-boil, anti-corrosion, and anti-scaling. Like water, it has advantages such as high specific heat, large latent heat of evaporation, and easy replenishment. When the ambient temperature drops below zero, water in the cooling system will turn into ice, posing a risk of expansion and cracking to cooling system components. The use of antifreeze ensures the normal operation of the engine in low temperatures.

What Causes the Abnormal Noise When Accelerating?

The causes of abnormal noise when accelerating are as follows: Abnormal noise from the fuel pump motor: When there is wear or impurities inside the fuel pump motor, abnormal noise will occur when accelerating. This issue requires replacing the fuel pump. Abnormal noise from the throttle: Modern throttles are electronic, and the motor controls the opening and closing of the throttle. When the motor gears are worn, insufficient engagement can cause abnormal noise. Excessive carbon deposits or sludge in the throttle can also lead to abnormal noise. The throttle can be cleaned, but if the motor is damaged, the throttle needs to be disassembled to replace the servo motor. If there is abnormal noise when accelerating, first check if the dashboard or workbench is loose, then inspect the transmission. Oil contamination inside the transmission can cause abnormal noise from the transmission oil pump.

What are the length, width, and height of the Vios?

The length, width, and height of the Vios are 4300mm, 1690mm, and 1490mm respectively. Below is some relevant information about the Vios: 1. Exterior: The Vios doesn't have much in terms of distinctive features, continuing the Japanese car style that generally appeals to Chinese consumers. The overall design is very harmonious, with smooth, rounded lines, a cute front face, and tail lights with fish-scale patterns, which still exude a sense of refinement. These elements align well with the aesthetic preferences of Chinese consumers. 2. Powertrain: The Vios is equipped with a domestically produced 16-valve 5A-FE engine. This engine is almost identical to the commonly used 8A engine in China, except for an increase in piston stroke, which raises the displacement from 1.3 liters to 1.5 liters. Correspondingly, the maximum power output is also increased to 68kw.
