How to Read a Spark Plug Heat Range Chart?

Spark plug heat range charts typically include numbers from 1 to 9, where 1-3 represent low heat range, 4-6 medium heat range, and 7-9 high heat range. Original equipment manufacturer (OEM) spark plugs usually come in heat ranges of 5, 6, and 7. The lower the number, the 'colder' the spark plug, meaning better heat dissipation. Below is an introduction to spark plugs: 1. Function of spark plugs: Spark plugs serve to conduct the high-voltage electrical pulse from the ignition coil into the combustion chamber, using the electrode's spark to ignite the air-fuel mixture, thus completing combustion. 2. Types of spark plugs: Common spark plugs are categorized into resistor spark plugs, platinum spark plugs, and iridium spark plugs. Generally, resistor spark plugs have a lifespan of 20,000 kilometers, platinum spark plugs last up to 40,000 kilometers, while iridium spark plugs can endure between 60,000 to 80,000 kilometers.

How many kilometers can you drive without repairing an engine that burns oil?

If the engine burns oil and is not repaired, the car can generally continue to drive as long as there is sufficient engine oil. Hazards of engine oil burning: If a car burns oil but is not repaired, it can cause the oxygen sensor to fail prematurely, leading to increased carbon deposits in the combustion chamber, unstable idling, poor acceleration, increased fuel consumption, excessive exhaust emissions, and other adverse effects. It can also cause blockage of the three-way catalytic converter, and in severe cases, the engine may be scrapped. Hazards of continuously adding oil without changing it when burning oil: Continuously adding oil without changing it when the engine burns oil is also not advisable. Burning oil increases carbon deposits, and the oil contains impurities, making it more prone to deterioration. If the oil burning is severe, the oil should be replaced immediately. During replacement, it is also necessary to clean the engine and remove carbon deposits.

Will the engine number change after replacing the engine?

After replacing the engine, the engine number will change. You need to bring the certificate of conformity of the new engine to the vehicle management office for registration. Introduction to engine numbers: The engine number is the engine model. The engine model is an identification code assigned by the engine manufacturer in accordance with relevant regulations, industry or enterprise practices, and the attributes of the engine, to identify a batch of identical products. It represents information such as the manufacturer, specifications, performance, features, technology, purpose, and production batch of the engine, including fuel type, number of cylinders, displacement, and brake power. The engine number consists of four parts, each with the following meanings: Front section: Includes the product series code, generation symbol, and local or enterprise code. Manufacturers can choose corresponding letters as needed, but they must be approved and registered by the industry standard regulatory body. Middle section: Composed of symbols representing the number of cylinders, cylinder arrangement, stroke, and cylinder diameter. Rear section: Composed of symbols representing structural features and usage characteristics. Tail section: Distinguishing symbol.

Do China V diesel vehicles have three-way catalytic converters?

China V diesel vehicles are equipped with three-way catalytic converters. Not all vehicles have three-way catalytic converters; in earlier years, vehicles produced in China that did not meet the China II emission standards were not equipped with them. Composition of the three-way catalytic converter: A three-way catalytic converter generally consists of four parts: the shell, damping layer, substrate, and catalyst coating. Shell: Made of stainless steel to prevent oxide scale from falling off, which could clog the substrate. Damping layer: Composed of gaskets or wire mesh pads, it serves to seal, insulate, and secure the substrate. To protect the substrate from damage caused by vibration, thermal deformation, and other factors, the gasket is made of expanded mica and aluminum silicate fibers, bonded together with adhesive. Substrate: Made of honeycomb-shaped ceramic material, though many also use metal (including stainless steel) materials. Catalyst: Composed of precious metals such as platinum, rhodium, and palladium, sprayed onto the substrate to form the purifying agent. Lifespan of the three-way catalytic converter: The lifespan of a three-way catalytic converter is generally between 80,000 to 100,000 kilometers. The specific lifespan depends on the vehicle's usage conditions, and it is also related to the quality of the fuel used and the driving environment.
