Power steering fluid and brake fluid are not the same, although they share similarities as hydraulic transmission fluids. Their functions differ. The "brake fluid" in a car, also known as "hydraulic brake fluid," serves as the liquid "medium" that transmits braking pressure in the vehicle's hydraulic braking system. Power steering fluid, sometimes referred to as "steering oil" or "steering fluid," is used in the steering system to transmit hydraulic pressure. It has higher viscosity, poorer fluidity, a distinct odor, and some corrosive properties. Below are the primary uses of power steering fluid and brake fluid: 1. Brake fluid. Apart from the braking system, it can, under certain conditions, substitute for clutch fluid. 2. Power steering fluid. In addition to its use in power steering systems, it can, under specific conditions, replace automatic transmission fluid (ATF).

Can Antique Cars Be Driven on the Road?

Antique cars can be driven on the road, but to be legally driven, they must pass motor vehicle inspections and have insurance. Below is an introduction to the relevant annual inspection content: Exceeding the Annual Inspection Period: No penalty will be imposed for being one day overdue. Vehicles that exceed the annual inspection period by less than one year can undergo a supplementary annual inspection procedure at the vehicle management department without facing penalties. However, if the annual inspection period is exceeded by more than one year, a penalty of 3 points deduction will be imposed, and the vehicle may be temporarily impounded. Penalties: For motor vehicles driven on the road without displaying an inspection compliance label, the vehicle may be impounded, and a 2-point deduction will be imposed. Failure to purchase compulsory traffic insurance will result in a penalty of twice the amount of the compulsory insurance premium.

Is It Necessary to Use Fully Synthetic Engine Oil for Cars?

It is necessary to use fully synthetic engine oil for cars. Fully synthetic oil offers better high and low-temperature performance, has a longer oil change interval, and performs better under harsher driving conditions. It has superior high-temperature resistance and is more effective at removing carbon deposits. Oxidation Stability of Fully Synthetic Engine Oil: Synthetic engine oil boasts exceptional oxidation stability, with its oxidation resistance being about 25% higher than that of conventional fully synthetic oil. This allows for more effective control over oil oxidation and degradation, extending the oil change period. Detergent and Dispersant Properties of Fully Synthetic Engine Oil: Synthetic engine oil features top-tier detergent and dispersant properties, with performance over five times that of mineral oil. It effectively reduces deposit formation, prevents engine wear, maintains robust engine power, and lowers fuel consumption.

What does 'mooe' mean in Chinese on a car?

On a car, 'mode' generally means pattern or direction. With the increasing number of car functions nowadays, most manufacturers use English abbreviations to label function buttons, which can be slightly inconvenient for some car owners without a basic understanding of English. Additional information: 1. From a literal perspective, 'mode' translates to pattern or direction in Chinese, and the mode button is commonly found on multifunction steering wheels and center consoles. 2. If the mode button is on the multifunction steering wheel, it is basically a button for switching between car multimedia modes, such as FM radio, AM radio, CD, or USB. 3. When playing the radio, CD, or an external audio source, pressing the MODE button will synchronize the display between the tachometer and speedometer with the MMI system. Then, by using the buttons to the left of the MODE button, you can scroll through and select songs on the central display screen. Pressing the wheel down will confirm the song change. Pressing the MODE button again will switch back to normal mode.

What lights should be turned on when obstructing traffic and difficult to move?

When a breakdown occurs, the 'hazard warning lights' must also be activated. Below is the relevant introduction: Regulations: If a motor vehicle breaks down on the road and needs to stop to fix the problem, the driver should immediately turn on the hazard warning lights and move the vehicle to a place where it does not obstruct traffic; if it is difficult to move, the hazard warning lights should remain on continuously, and warning signs should be set up in the direction of oncoming traffic to increase the warning distance. If necessary, the police should be called promptly. Details: When driving at night and the headlights are on, the 'position lights' are also turned on. The 'position lights' do not need to be turned on separately or specifically. In case of a breakdown, the 'hazard warning lights' must also be activated to alert vehicles behind. Additionally, a 'warning triangle' must be placed about 100 meters behind the vehicle to warn approaching vehicles. All occupants of the vehicle should move outside the traffic lane.

Diesel vehicles use urea to reduce exhaust emissions and protect the atmospheric environment. Here are the relevant details: Adding urea to diesel vehicles helps convert harmful nitrogen oxides in the exhaust into nitrogen and water, thereby reducing hazardous emissions. The main components of a diesel engine include: 1. Engine block, consisting of the cylinder block, cylinder liner, cylinder head, cylinder gasket, oil pan, flywheel housing, timing gear housing, and front/rear mounts. 2. Crankshaft linkage mechanism, comprising the crankshaft, connecting rod, piston, and piston pin. 3. Valve train, made up of the timing gear, camshaft, tappet, pushrod, and rocker arm. 4.
