Vacuum-assisted braking system is also known as vacuum brake booster system and vacuum servo brake system. The servo brake system is based on manual hydraulic braking, with an additional set of power-assisted devices provided by other energy sources to generate braking force, allowing the combination of human power and mechanical power. In other words, it utilizes both human power and engine power as braking energy sources. Additional information: 1. The braking systems of passenger cars and light commercial vehicles mainly use hydraulic pressure as the transmission medium. Compared to pneumatic braking systems that can provide a power source, they require a power-assisted system to aid the driver in braking. 2. Under normal circumstances, its output working pressure is mainly generated by the power servo system. Therefore, when the power servo system fails, the hydraulic system can still be fully driven by human power to generate a certain degree of braking force.

What are the causes of a blown engine cylinder head gasket?

Engine cylinder head gasket failure causes: 1. Elongation or loosening of cylinder head bolts/nuts, resulting in insufficient pressure and uneven pressure distribution between cylinder head and engine block mating surfaces, allowing high-temperature high-pressure gases to escape through areas with lower local pressure and burn the gasket; 2. Deformation of mating surfaces between cylinder head and engine block - if these surfaces warp, uniform gasket compression cannot be maintained, causing gas leakage and gasket burnout; 3. Improper installation procedures including unclean mating surfaces, incorrect tightening sequence of cylinder head bolts/nuts, insufficient or uneven torque application, or inadequate/uneven protrusion of cylinder liners above engine block surface; 4. Substandard gasket quality issues such as uneven thickness, imperfect rolled edges, insufficient elasticity, poor material quality, surface irregularities, or physical damage during handling/installation.

What are the impacts of a water-damaged vehicle?

Impacts of a water-damaged vehicle: 1. It may cause water to enter the engine, leading to issues such as insufficient power and shaking. Prolonged use can result in deformation or breakage of the piston connecting rod, ultimately damaging the engine. 2. It may cause the high-voltage distribution system to become damp or short-circuited due to water ingress, leading to engine stalling. Post-water exposure handling methods: 1. If the exhaust or intake ports have been submerged during water exposure, the vehicle must be towed to a repair shop for inspection. Do not attempt to forcibly start the engine, as this may cause greater damage due to ineffective engine lubrication. 2. If water has entered the passenger compartment during water exposure, the repair process mainly involves draining the accumulated water inside the vehicle. There are several sealing strips located at the lower part of the vehicle chassis; opening these strips can help drain the water from the compartment. However, since the adhesive used in interior decorative materials is highly absorbent, the floor mats should be removed and placed in a spacious area to facilitate water evaporation.

What are the benefits of engine cleaning?

Engine cleaning serves several purposes: 1. Cleaning sludge from oil passages - The engine block contains numerous oil passages, and engine cleaning agents can remove sludge and debris from these passages to ensure the proper functioning of the lubrication system; 2. Removing carbon deposits from piston rings - When the engine cleaning agent is added to the engine oil, it cleans residual carbon deposits from the piston rings and ring grooves as the oil spreads on the cylinder walls; 3. Maintaining the engine - By removing substances like sludge and carbon deposits that affect normal engine operation, the engine's performance can be improved, and its service life extended.
