What is the principle behind the GTR's flame spitting?
1 Answers
GTR spits flames due to its "Anti-Lag-System" (ALS). Related introduction: 1. Overview: The Anti-Lag-System, abbreviated as ALS, stops the ignition action when lifting the throttle to shift gears, deliberately allowing the fuel-air mixture to enter the exhaust header after the exhaust valve opens. Since the header's temperature is high, the mixture explodes upon contact. 2. Extension: The powerful explosion pressure drives the exhaust turbine blades, which in turn causes the turbine's compressor blades to rotate at high speed, maintaining boost pressure. This ensures a boost effect even when the vehicle is at low speed or during gear shifts when the throttle is lifted.
