What are Rev-Matching for Upshifts and Downshifts?

[EmersonDella]

Here is the introduction to rev-matching for upshifts and downshifts: 1. Downshift rev-matching operation method: When the vehicle is moving uphill and its speed decreases with noticeable engine load changes, depress the clutch to shift from 5th gear to neutral, quickly tap the throttle and release, then engage 4th gear while slightly increasing throttle to prevent speed loss. The same procedure applies when shifting from 4th to 3rd gear. 2. The vehicle's throttle, typically controlled by a pedal (also called accelerator pedal), is the device regulating fuel supply to the engine. Operate the throttle pedal by placing your right heel on the floor as a pivot, gently pressing the accelerator with your foot, using ankle joint movements to depress or release. 3. When operating the throttle pedal, apply force gently with smooth pressing and gradual releasing. During engine startup, avoid fully depressing the throttle pedal - keeping it slightly above idle throttle is preferable. For starting off, apply throttle slightly before the clutch engagement point, with moderate throttle opening being optimal. Coordinate clutch release precisely with throttle application for agile operation.
