Does Increasing Air Intake Enhance Car Performance?
1 Answers
Increasing the air intake in a car can enhance performance because a larger air intake volume results in a leaner air-fuel mixture. The oxygen sensor on the exhaust pipe detects this change and adjusts the fuel injection to maintain normal emissions. Methods to Enhance Car Performance: Engine Modification: The most effective way to boost performance is by upgrading the ECU program. This modification can alter the engine's ignition timing, fuel injection timing, RPM limit, torque limit, and more, enabling the engine to operate more efficiently. Ignition System Modification: The ignition system is a critical component of the engine, comprising the power source, ignition trigger signal, ignition timing control signal, high-voltage ignition coil, high-voltage wires, and spark plugs. The quality of ignition performance and the timing of ignition significantly affect fuel combustion efficiency, indirectly influencing engine power. Therefore, modifying the ignition system primarily aims to address the shortcomings of the original system, focusing on precise ignition timing, increasing ignition intensity, extending ignition duration, and reducing voltage transmission losses. Air Intake Modification: There are several methods to modify the air intake system. Installing a high-performance intake manifold is a highly effective approach. Original intake manifolds are typically cast, featuring rough inner walls and noticeable mold lines, which negatively impact intake efficiency and airflow smoothness. High-performance intake manifolds have smoother inner walls, improving intake efficiency without losses. Additionally, upgrading to a mushroom-style air filter and installing an intake turbo in the intake hose are both effective and cost-efficient modification methods.
