What is the difference between HFC134a and R134a?

1 Answers

HFC134a and R134a have the following differences: 1. Chemical molecular expression: R134a, molecular formula: CHF2CHF2 (tetrafluoroethane), molecular weight: 102.03, boiling point: -26.26°C, critical temperature: 101.1°C, critical pressure: 4067 kPa. HFC134a, molecular formula: CH2FCF3 (tetrachloroethane), molecular weight: 102.03, boiling point: -26.1°C, critical temperature: 101.1°C, critical pressure: 4010 kPa. From the above, it can be seen that R134a and HFC134a are two different substances, but their physical properties are basically the same and can be used interchangeably. 2. Refrigerant model: Both R134a and HFC134a have an ODP value of zero. Their low toxicity makes them very effective and safe substitutes to replace CFC-12 used in the refrigeration industry. R134a and HFC134a are mainly used in automotive air conditioning, household appliances, small fixed refrigeration equipment, medium-temperature refrigeration in supermarkets, and industrial and commercial refrigeration units.

What Causes the Electronic Parking Brake to Become Louder?

Electronic parking brake becoming louder may indicate an issue with the brake caliper. Below is relevant information about electronic parking brakes: 1. Introduction: The car electronic parking brake, also known as the Electronic Parking Brake system (EPB), is marked with a "P" button in vehicles. It operates on the same principle as traditional mechanical handbrakes by using friction between the brake disc and brake pads to achieve parking brake control, except that the control method has changed from mechanical handbrake to electronic buttons. 2. Function: The car electronic parking brake is mainly used for long-term braking after parking, similar to traditional mechanical handbrakes. With the development of electronic parking brake systems, the functionality of electronic parking brakes has expanded from basic parking functions to include automatic parking functions (AUTO-HOLD), allowing drivers to avoid prolonged braking when the vehicle is stationary.

What is the reason for no alarm when the engine oil is below the minimum level?

If the engine oil is below the minimum level but there is no alarm, it could be due to a faulty level sensor or the engine model may not have a level sensor. If a level sensor is present, it is necessary to visit a 4S shop or repair shop for servicing to ensure proper functionality in the future. Below are the impacts of insufficient engine oil on the vehicle: 1. When the engine oil is at the minimum level, it leads to poor lubrication of the friction surfaces of various internal engine components. Insufficient lubrication can exacerbate the wear and tear of the parts. 2. If the engine oil is insufficient, the cooling and heat dissipation capacity of the engine decreases, causing the engine to overheat. This can further result in phenomena such as bearing corrosion and cylinder scoring. During driving, symptoms such as insufficient vehicle power and excessive oil consumption may be noticeable.

What is the autonomous driving level of the NIO ES8?

The NIO ES8 has an autonomous driving level ranging from L3 to L5. Below are specific details about the NIO ES8: Interior: In terms of interior design and material upgrades, the digital cockpit has been fully upgraded to feature a 9.8-inch ultra-narrow bezel digital instrument cluster and an 11.3-inch high-definition multi-touch central control screen. The NOMI Mate 2.0 is equipped with the automotive industry's first AMOLED full-circle screen, significantly improving display area and quality. Additionally, the new ES8 comes with high-tech features such as a smart charging port cover and an NFC card-style car key. Exterior: The new ES8's exterior offers a fresh interpretation of the NIO family design while maintaining its heritage, appearing sharper and more modern.

Why does the car feel sluggish in acceleration and the throttle becomes heavy?

Car feeling sluggish in acceleration and the throttle becoming heavy is mainly caused by excessive carbon deposits in the engine. It is necessary to clean the throttle, check for carbon deposits in the fuel injectors, and inspect whether the spark plugs are functioning normally. If the spark plugs are aged, they need to be replaced. For both automatic and manual transmission cars, it is recommended to maintain a steady speed under the same road conditions, as this helps in saving fuel. During car maintenance, attention should be paid to details, such as timely cleaning of carbon deposits in the fuel injectors. The engine, throttle, and combustion chamber are all prone to carbon deposits, which requires the owner to perform timely vehicle maintenance and regular cleaning to extend the engine's lifespan.

What engine does the Domain Tiger 3 use?

The Domain Tiger 3 is equipped with two types of engines: a 2.5T turbocharged diesel engine and a 1.8T turbocharged gasoline engine. The 2.5T turbocharged diesel engine delivers a maximum power of 92kW and a maximum torque of 310Nm, while the 1.8T turbocharged gasoline engine produces a maximum power of 130kW and a maximum torque of 280Nm. The Domain Tiger 3 has a body length of 5410mm, width of 1905mm, height of 1795mm, and a wheelbase of 3085mm. The front fascia features minimal embellishments, with a trapezoidal large-mouth grille that offers high recognition. The lower black plastic cladding helps prevent minor collisions from damaging the paint. The large front headlights adopt a split design for high and low beams, both using halogen light sources, with the low beams equipped with lenses.

Does a smaller wheel hub ET value result in more concave wheels?

Wheel hub (Car-Rim) is the central part of the wheel where the axle is installed, also known as the "rim" or "steel ring". The smaller the ET value of the wheel hub, the more space there will be on the inner side of the wheel. Here is a detailed introduction about car wheel hubs: 1. Overview: Wheel hubs are prone to accumulating dirt, and if not cleaned for a long time, they may corrode and deform, posing safety hazards. 2. Classification: Wheel hubs can be divided into steel wheel hubs and alloy wheel hubs based on material, each with its own advantages and disadvantages. The main advantage of steel wheel hubs is their simple manufacturing process (usually produced by casting, whereas aluminum alloy wheel hubs are generally manufactured using low-pressure casting processes), relatively low cost, and strong resistance to metal fatigue.
