Automotive air conditioning refrigerant hoses are the core flexible fluid-transfer components within the vehicle’s air conditioning refrigeration circuit. Specifically, they refer to specialised hose assemblies manufactured using a multi-layer composite structure, designed to transfer refrigerant and associated refrigeration oil in a sealed manner between key components of the vehicle’s air condit...
With the rapid development of the automotive industry, automotive air-conditioning systems have significantly enhanced driving and passenger comfort, and there is growing emphasis on their functional requirements and technological innovation. The performance of the air-conditioning system relies on the connections within the piping system, such as high-pressure and low-pressure lines; consequently...
Summer is just around the corner. As we all know, a good car air-conditioning system can cool the car down quickly and ensure a comfortable drive, but we often don’t really know how to use the air-con properly or how to maintain and look after the system. We often find ourselves in this situation: when we switch on the car’s air conditioning in sweltering, blazing heat, we discover that the system...
The EU’s stringent carbon emission regulations are driving the acceleration of electrification, yet Europe faces a severe shortage of domestic production capacity for batteries, electric drive systems and smart components, coupled with slow technological advancement and a reliance on external supplies. In 2024, China’s exports of automotive components totalled US$93.43 billion, with Europe represe...
SAE J188 High-Capacity Intumescent Power Steering Hose Application: For vehicles equipped with power steering systems, used to transmit pressure within the power steering unit. Operating temperature: -40°C to 121°C, with a peak temperature of up to 135°C. Standard inner diameter: 3/8”. The primary material is CSM, which offers excellent resistance to ozone, ageing, chemical corrosion, high and low...
If you hear a ‘creaking’ noise coming from the car’s chassis, accompanied by the steering wheel pulling to one side whilst driving, it could be a problem with the suspension bushings. Today, we’ll take a look at what you need to know about car bushings. What is an automotive bushing? In mechanical design, the connection of moving parts is a common requirement; however, relative motion between comp...
Air conditioning piping connects the four major components of the system—the compressor, condenser, evaporator and expansion valve—to form a closed system, within which the refrigerant is stored or circulates. When the air conditioning system is in operation, the refrigerant circulates continuously, exchanging heat with the outside environment to achieve the cooling function. To ensure the refrige...
1. The power steering feels heavy or lacks assistance Symptoms: Heavy steering, with brief loss of hydraulic power assistance Causes of fault: ① Loose V-belt on the oil pump ② Oil level in the reservoir too low ③ Insufficient oil pump pressure ④ Pressure control valve sticking ⑤ Excessive external leakage ⑥ Excessive internal leakage ⑦ Steering shaft bushi...
Power steering fluid is a vital fluid that provides power assistance to the steering system, helping the driver to manoeuvre the vehicle with ease. Due to various factors such as duration of use and environmental conditions, the power steering fluid must be checked and replaced after a certain period of use. The procedure is as follows: 1. Align the front wheels so that they are pointing straight ...
