Provide the timely 2nd stream of oxygen.

Relatively increase 2 ~ 3 liter/m torque of the car engine.

Shorten the running distance required for shifting gears, save 7% ~ 20% of fuel, and reduce 10% or more of the emission of carbon dioxide.

When car running at a high speed, the torque booster can reduce the rotation rate by 200 ~ 300 revolutions, reduce gear abrasion, and promote the life of the engine.

For a new car, the torque booster can prevent carbon accumulation; for an old car, the torque booster can eliminate carbon accumulation, and smoothen the engine operation.
