What Do the Letters on Spark Plugs Mean?

B stands for semiconductor type, C indicates a nickel-copper alloy center electrode, G represents precious metal electrode, J denotes multi-electrode type, R signifies resistor type, T designates insulator-tipped type, and V indicates V-groove spark plug. What are spark plugs composed of: Spark plugs mainly consist of terminal nut, insulator, terminal stud, center electrode, ground electrode, and metal shell. What types of spark plugs exist: The main types of spark plugs include: standard spark plugs, projected insulator spark plugs, electrode-type spark plugs, seat-type spark plugs, multi-electrode spark plugs, and surface-gap spark plugs. How spark plugs work: Under high voltage, the air between the center electrode and ground electrode of a spark plug rapidly ionizes, forming positively charged ions and negatively charged free electrons. When the voltage between electrodes reaches a certain level, the number of ions and electrons in the gas increases like an avalanche, causing the air to lose its insulating properties and forming a discharge channel, resulting in a "breakdown" phenomenon. At this point, the gas forms a luminous body known as a "spark." Accompanied by thermal expansion, it also produces a "snapping" sound. This electrical spark can reach temperatures of 2000-3000°C, sufficient to ignite the air-fuel mixture in the engine combustion chamber.

Is the Leiling Electronic Parking Brake Automatic?

Leiling's electronic parking brake is automatic. When the electronic parking brake is engaged, no manual operation is required. Once the vehicle comes to a complete stop and the gear is shifted into P (Park), the electronic parking brake automatically activates, eliminating any need for concern or additional action. After shifting into P, simply lock the vehicle. The Leiling is a compact sedan based on Toyota's MC platform, specifically tailored for Chinese consumers. It measures 4630mm in length, 1775mm in width, and 1480mm in height. The Leiling CVT Premium Edition is equipped with a 1.2T inline four-cylinder turbocharged engine, delivering a maximum power of 85kW and a peak torque of 185Nm, paired with a CVT (Continuously Variable Transmission).

What are the benefits of changing spark plugs?

Replacing spark plugs can improve vehicle performance, as spark plugs themselves are wear-prone components that require regular replacement. The spark plug is a crucial part of the engine's ignition system, responsible for generating sparks that ignite the air-fuel mixture in the engine. When the mixture burns, it pushes the piston downward, enabling the engine to produce power. If the spark plug fails to ignite, the air-fuel mixture won't combust, and the engine won't function. Over time, the electrode gap in spark plugs widens, reducing ignition efficiency. Additionally, prolonged use leads to carbon buildup on the electrodes, further diminishing the spark plug's ignition capability.
