Hello Jing Sheng Ru Xu! Regarding the questions you've asked, your Corolla meets the National II emission standard, which is also known as GB18352.2-2001. The GB18285-2005 refers to the emission limit standards of dual idle speed method and simplified condition method, which does not even reach the requirements of National III. If the original vehicle has not been equipped with an OBD system, it cannot be installed separately afterwards. If the car you mentioned currently has a Beijing license plate, then the transfer procedures can be handled in Beijing. However, if it's registered elsewhere, it cannot be transferred and re-registered in Beijing. To improve the ignition performance of the ignition system, the engine ignition efficiency can be effectively enhanced through the following methods.
Tools/Materials: Car Engine
Steps/Methods:
1. Replace ordinary high-voltage ignition wires with high-energy high-voltage ignition wires. In order to increase the ignition energy of the engine, manufacturers specifically provide high-energy high-voltage ignition wires for modified cars, known as "silicon conductor wires." These high-voltage ignition wires have much lower internal resistance than regular ones, allowing better passage of ignition current and increasing ignition energy.
2. Increase the voltage of the high-voltage coil. By improving the material of the coil or using ignition coils with a higher ratio of secondary to primary coil turns, higher ignition voltages can be generated, and they can handle higher current output loads. Increasing ignition voltage has a direct and positive impact on enhancing ignition energy.
3. Replace with high-energy spark plugs. High-energy spark plugs can withstand higher thermal and mechanical loads and adapt to higher ignition voltages, ensuring sufficient ignition energy. For example, spark plugs with iridium alloy electrodes can endure extremely high temperatures without melting and have excellent wear resistance, extending their lifespan.
Precautions:
Special attention should be paid to the reasonable matching of the car engine and transmission system. When improving the car engine, after factors such as the total mass of the car, quality distribution, air resistance, and tire rolling resistance are determined, the reasonable matching of the engine and power transmission system is very important for ensuring the car's power performance and fuel economy. The power performance of a car is determined by the overall performance of the powertrain, where the engine plays a very important role. However, when the engine displacement and output power do not differ significantly, the cooperation situation of the powertrain is the most critical factor determining the car's output power. Comprehensive optimization of the vehicle's power system, ensuring reasonable coordination between the engine, transmission, and main reducer, allows the engine's output power to be fully released.
