What do LH and RH mean in cars?

[JackFitz]

In cars, LH and RH represent left and right respectively. Here are more automotive-related terms: 1. 5V: The 'V' stands for the first letter of the English word 'valve'. Traditional car engine cylinders commonly use a 4-valve structure, i.e., 2 intake valves and 2 exhaust valves, ensuring sufficient and effective intake and exhaust, which is beneficial for increasing engine speed to achieve maximum power. The 5-valve technology has been widely adopted by foreign automotive companies, and the recently launched 'Bora' in China already employs this technology, featuring 3 intake valves and 2 exhaust valves. 2. ABS: This is the abbreviation for 'anti-lock-brake-system', translated in Chinese as 'anti-lock braking system'. It is a safety brake control system with advantages such as anti-skid and anti-lock. Cars without ABS may lock the wheels when the driver slams the brakes in an emergency, leading to dangerous situations like skidding, deviation, or loss of steering control due to the vehicle's momentum. 3. GPS: Short for Global Positioning System, its main functions include anti-theft, anti-hijacking, and navigation.
