The bore goes down from the old 81mm to 45mm. The DVT system varies the oil pressure in chambers inside of an external housing affixed to cam belt pulleys to adjust the camshaft timing via an internal mechanism attached to the camshafts. This optimizes combustion without increasing emissions, by completing the oxidisation of unburned hydrocarbonsto testastreyta HC and CO levels. The overlap angle is defined as the interval of crankshaft rotation, expressed in degrees, during which both the intake and exhaust valves are open at the same time.
