What are the professional terms in the automotive field?

Professional terms in the automotive field include ABS, spark plugs, steering systems, engine systems, etc. Taking ABS as an example, the following is a detailed introduction to automotive ABS: Overview: The Anti-lock Braking System (ABS) is designed to automatically control the braking force during vehicle braking, preventing the wheels from locking up and maintaining a rolling-sliding state (with a slip ratio of about 20%). This ensures that the adhesion between the wheels and the ground remains at its maximum. Classification: In ABS, the brake pipelines capable of independently adjusting braking pressure are referred to as control channels. ABS systems are categorized into four-channel, three-channel, two-channel, and single-channel configurations.

Automotive terminology is actually quite extensive, like learning a new language. Engine-related terms include bore, stroke, and compression ratio—these numbers directly affect a car's power. For transmissions, you often hear about MT (manual transmission) and AT (automatic transmission), and nowadays there are also CVT (continuously variable transmission) and DCT (dual-clutch transmission). In terms of chassis, terms like MacPherson suspension and multi-link suspension come up, and the difference is how bumpy the ride feels over speed bumps. Drivetrain options include front-wheel drive, rear-wheel drive, and four-wheel drive—four-wheel drive really does feel more stable in snowy conditions. Safety features like ABS (anti-lock braking system) and ESP (electronic stability program) can be lifesavers in critical moments. Other parameters, such as wheelbase (which determines rear-seat space) and ground clearance (which affects off-road capability), are all things to consider carefully when choosing a car.

Common professional terms encountered in daily car use: fuel consumption refers to the MIIT comprehensive fuel consumption rating, and maintenance requires changing to engine oil with a viscosity grade of 5W-30. Mechanics often mention oxygen sensor failures or timing belt wear during repairs, which can be confusing. Tire specifications like 205/55 R16 indicate tire width with the first number, while the letter R stands for radial tires. When buying insurance, comprehensive coverage and third-party liability are must-consider items, and used car purchases require checking the VIN (Vehicle Identification Number). Performance parameters such as maximum horsepower in 'ps' and torque determining acceleration speed differ significantly between turbocharged (T) and naturally aspirated (L) engines. For new energy vehicles, the frequently mentioned three-electric system comprises the battery, motor, and electronic control, with notable differences between NEDC and CLTC range standards.

The terms that come out of the mouths of car modders sound next-level: flashing the ECU to boost power, installing coilovers to adjust ride height. The exhaust headers, mid-pipes, and tailpipes affect the sound, while an LSD (limited-slip differential) makes cornering sharper. Lightweight forged wheels and multi-piston brake calipers with drilled rotors are performance staples. Power-to-weight ratio is the key metric, and aerodynamics is all about downforce. On the track, terms like trail braking and heel-toe shifting get thrown around—skills that take years to master. The difference between 95 and 98 octane fuel lies in their ratings, with high-compression engines demanding higher octane.

Vehicle construction terms can be broken down: In the engine compartment, the throttle valve controls air intake, while the catalytic converter treats exhaust. The chassis includes components like the steering tie rod and stabilizer bar, with the drive shaft connected to the transmission. The electrical system mentions the ECU control unit and CAN bus communication protocol. For the air conditioning compressor, power is measured in horsepower, and environmentally friendly R134a is now commonly used as refrigerant. Lighting configurations are divided into halogen, xenon, and LED, with lumen values determining brightness. Measurement units like Newton-meters for torque, bar for tire pressure, and liters for displacement indicate engine size. These terms are particularly useful during vehicle repairs.

From a production perspective, there are also many professional terms: the stamping workshop produces door panels, the welding workshop uses spot welding robots. The painting process includes electrophoretic anti-rust treatment, and the assembly line installs interiors and powertrains. Quality inspection involves four-wheel alignment and lighting tests, while road tests evaluate ESP intervention timing. Crash test terminologies like 25% offset collision and whiplash tests directly affect safety ratings. In terms of materials, hot-stamped steel offers higher strength, and NVH technology is used for sound insulation. New car evaluations differentiate between regular cruise control and adaptive cruise control based on automatic following capability, while automatic parking depends on ultrasonic radar accuracy.
