Vvt Vs Vtec !!top!! File

Modern systems often use cam phasing to fine-tune the engine's response across the entire rev range, while utilizing VTEC-style lobes to provide the massive airflow needed for peak horsepower.

If you are looking at a brand-new Honda Civic Type R or a modern performance car, you might see terms like "i-VTEC" or "VVT-i." vvt vs vtec

Honda’s VTEC (introduced in the 1989 Integra) is a mechanical on/off switch. Each pair of valves has three rocker arms: two outer arms (low RPM) and a middle arm (high RPM). Modern systems often use cam phasing to fine-tune
