What is the normal pressure for car air conditioning refrigerant?

Under compressor conditions of 1500~2000rpm, the normal high pressure (discharge pressure) is around 1.5~2.0mpa, and the low pressure (suction pressure) is around 0.15~0.35mpa. The specific values depend on different vehicle air conditioning system configurations and ambient temperatures. Here are relevant introductions: 1. Car air conditioning refrigerant: The so-called car air conditioning refrigerant is commonly referred to as Freon, also known as "refrigerant" or "coolant" in the market, which is divided into environmentally friendly types (R134a) and non-environmentally friendly types (mainly F12). 2. Refrigerant pressure gauge: The refrigerant pressure gauge, also called a refrigerant meter or Freon gauge, is used to measure the current pressure of the refrigeration system. It is mainly used to detect the pressure values of the refrigerant at different stages of the system, helping operators understand the operating status of the equipment. Currently, China requires the accuracy of refrigerant pressure gauges to reach grade 2.5.

Where is the air conditioning filter located in the Haima M5?

The air conditioning filter in the Haima M5 is located behind the glove compartment on the passenger side. The replacement method is as follows: 1. Locate the air filter slot, open the clip located at the front of the passenger side in the engine compartment and remove it; 2. Reach into the baffle to take out the air conditioning filter. There is an arrow indicator on the outer side of the filter for proper installation. The Haima M5 is positioned as a compact sedan, with body dimensions of 4698mm in length, 1806mm in width, and 1477mm in height, and a wheelbase of 2685mm. In terms of power, the Haima M5 is equipped with a 1.6L naturally aspirated engine, which is the second-generation product independently developed by Haima, with a maximum power of 92kW and a peak torque of 161Nm.

What are the components of the piston connecting rod assembly?

The piston connecting rod assembly mainly consists of the piston, piston rings, piston pin, connecting rod, and connecting rod bearing shells. Here is a detailed introduction to the piston connecting rod assembly: 1. Working principle: The piston connecting rod assembly converts the reciprocating motion of the piston into the rotational motion of the crankshaft, while transforming the force acting on the piston into the torque output by the crankshaft, thereby driving the rotation of the vehicle's wheels. 2. Pressure transmission: The piston connecting rod assembly serves as the transmission component of the engine, transferring the pressure of the combustion gases to the crankshaft, causing the crankshaft to rotate and output power. 3. Common faults of the piston connecting rod assembly: Due to oil starvation, issues such as damage to the connecting rod bearing shells, piston cylinder collision, cylinder head collision, connecting rod crankshaft damage, piston ring breakage, and excessive piston clearance may occur.

Do pure electric vehicles require annual inspection?

New energy pure electric vehicles do require annual inspections. Whether it's a pure fuel-powered model, an electric model, or a hybrid model, private passenger vehicles need to undergo on-site testing after six years of use. Non-commercial passenger vehicles require annual inspections between 6 and 15 years of use, and after 15 years, they need to be inspected every 6 months. Therefore, new energy pure electric vehicles also require annual inspections, although the inspection content differs. Annual inspection time regulations: The first annual inspection for passenger cars is conducted when they reach six years of use. Non-commercial small and micro passenger vehicles, including family cars over 6 years but under 10 years old, require biennial inspections. For vehicles exactly six years old, the annual inspection requires driving the vehicle to the inspection station with the owner's ID card, vehicle license, vehicle and vessel tax or tax exemption certificate, and compulsory traffic insurance policy. After passing the inspection, a certificate will be issued, which, along with the other documents, must be presented at the relevant window to obtain the annual inspection sticker.

What does the D gear plus and minus mean?

D gear plus and minus mean The "+" and "-" signs next to the D gear are unique functions of manual-automatic transmission models, which are used for upshifting or downshifting in the manual mode of the transmission. The manual mode is often marked as M gear or S gear. Many people drive manual-automatic transmission cars in D gear all the time, not knowing when to switch to M gear, thinking that they have to wait until the car stops to switch. In fact, it is not necessary, and you can switch from D gear to M gear at any time. The following is an introduction to the S gear: 1. Introduction: It keeps the engine at high speed for a long time, allowing the car to move at high speed in low gear for a long time, thereby obtaining greater torque output and acceleration. 2. Precautions: Because the S gear only delays upshifting without changing other working links, it will inevitably increase the load of the transmission in a short time, and the temperature will also rise accordingly, and the wear will also increase. Therefore, try not to use the S gear for a long time.

How to Replace the Battery in a Trumpchi GS4 Key?

On the back of the remote battery, press the button in the direction indicated by the arrow and pull the mechanical key outward. The mechanical key can be used to open the car door when the smart key runs out of battery, but it cannot start the engine. After removing the mechanical key, you can open the remote key by using your fingernail to pry open the gap on the side of the key—it's not complicated. Once opened, you will see the battery compartment on the back cover. Follow the instructions to remove the old battery and replace it with a new one. Then, close the back cover and reassemble the key. Here is some additional information: Trumpchi GS4: The new GS4 has undergone adjustments and upgrades in its detailed design. The most significant changes to the front face come from the headlights and fog lights, with overall lines appearing more youthful and sporty. The rear changes also focus on the light clusters, with large-sized light strips enhancing the rear's recognizability. The new Trumpchi GS4 still uses the 1.3T and 1.5T engines, with maximum power outputs of 101kW (137PS) and 112kW (152PS), respectively. The transmission options have been upgraded to include a 6-speed manual, 6-speed automatic, and 7-speed dual-clutch.
