8. When fuel is burned completely it increases fuel effi ciency and decreases hydrocarbon emissions Improved throttle response is another benefit of VVEL When the throttle plate is suddenly opened on a conventional throttle engine it takes time for the intake manifold to fill with air and for the vacuum to become equal to atmospheric pressure This delay results in a lag time between when the accelerator pedal is pressed and when the engine output reaches the desired level On the other hand the response on a VVEL engine is near instant The power output match es the accelerator input in virtually real time Finally maximum valve lift can be increased without negatively affecting idle quality On a conventional throttle engine valve litt must be balanced between what is optimal for idle and what is optimal for maxi mum load Creating a cam profile that has a lot of lift will also increase the duration the ramps up and the ramps down can only be made so steep At idle exces sive lift will cause poor air velocity and fuel atomization and excessive duration will cause blowback into the intake manifold If a camshaft is created for maximum power idle quality will suffer If a cam is created for the best idle quality maximum output will suffer With VVEL the best of both profiles can be used without sacrificing anything a silky smooth idle and up to over 400 horsepower As you may have gathered the benefits of VVEL are most
