What is a DVVT engine?

It means that the engine adopts variable timing technology of intake and exhaust valves.

The full name of DVVT is dual variable valve timing, which means the variable timing technology of intake valve and exhaust valve. The engine with DVVT technology is more efficient, energy-saving and environmentally friendly than the engine with intake valve timing technology widely used in the market at present.

DVVT technology can reduce fuel consumption by 5%, improve power 10%, reach the power index of 2.0 displacement, and exhaust emissions reach the national IV standard.

Influence of engine valve timing on its dynamic performance;

Economy and exhaust pollution have an important impact. The best valve timing should make the engine charge the most fresh air in a short ventilation time.

And minimize exhaust resistance and exhaust residue. When the engine speed changes, the speed of airflow and the absolute time of early opening and late closing of intake and exhaust valves change.
