QUOTE(Jazz6218 @ Feb 15 2012, 10:04 AM) p321a to replace persona or inspira?some source say persona some source say inspira if u look at the variant.. it will be more logic to replace persona ..  the 2 executive ones are still using IAFM @ S4PH @ campro 1.6 with IAFM .. which is the current PERSONA engine. |

QUOTE(dvinez @ Feb 16 2012, 10:50 AM) b. variable valve timing - dvvt, vvti = cvvt? or different? same proton CFE uses vvt only ... inlet only .. exhaust valve tada variable timing . all is continuous .. at different RPM , different load , the valve advance/retard by certain degree depends on condition. |

QUOTE(dares @ Feb 16 2012, 11:49 AM) VVTi and DVVT is continuous meh? continuous is just a TERM they use ..wat ever VVT .. all function the same geh .. at different LOAD , different RPM ... the ECU will read the VVT (or wat ever map) .. and advance/retard the timing according to the situation .. if u ask me in terms of logic .. it is consider CONTINUOUS as well .. as ur RPM is not STUCK in the same position and ur LOAD is not the same when u are driving ma... so the valve vary depends on situation and continously till u OFF ur engine lo |

QUOTE(dares @ Feb 16 2012, 02:00 PM) Thanks for the info. those are not call VVT ..Isn't there are another kind of VVT or VVL systems that are not continuous? Such as the VTEC, the older MIVEC and Proton's CPS that swap cams on preset RPMs. Hence the term "continuous" to differentiate between these systems and the continuous ones. VVTi and DVVT are continuous, though, AFAIK. vvt stands for variable valve timing ... it actually advance the valve open or retard the valve open .. VTEC, MIVEC (The older days MIVEC, not the current Lancer one) .. CPS .. those are call LIFT ... the technology is totally different.. it has a 2ndary cam loop .. when it engage.. the valve will open base on the 2ndary loop. its like changing cam instantly .. normally these cam (2nd cam) have higher loops .. means the valve open DEEPER .. allow more air to go in .. it does not have the capability to change the timing instantly .. but it will base on the timing on the 2nd cam .. if u know about HIGH cams.... bad for idling .. got for high end power ... VTEC, OLD MIVEC, CPS .. is like the engine will switch instantly to the 2ndary HIGH Cam at certain RPM .. tahts why u hear ppl says VTEC KICK IN .. summarize .. VVT --> more to fuel saving LIFT --> more to powar ... |

QUOTE(dares @ Feb 16 2012, 02:16 PM) Emm sorry I'll have to call you out on that. "MIVEC was first introduced in 1992 in their 4G92 powerplant, a 1,597 cc naturally aspirated DOHC 16 valve straight-4.[2] At the time, the first generation of the system was named Mitsubishi Innovative Valve timing and lift Electronic Control" VTEC and MIVEC are both variable valve timing systems, not valve lift. http://en.wikipedia.org/wiki/VTEC http://en.wikipedia.org/wiki/MIVEC The first paragraph of each article pretty much sums it all up. You're are right about CPS is variable valve lift. Added on February 16, 2012, 2:20 pmAnyway, from my research: Early VVT systems are cam-switching systems, which means the engine will switch to different cams with different cam lobes based on a preset RPM. New VVT are continuous, either through cam-phasing or adjusting the cam belt tension or some other obscured method. The point is it will continuously adjust the valve timing instead of switching cams are preset RPMs. Just sharing, correct me if I am wrong again .. its a jargon only ... the naming ... wat i trying to says is why VTEC and MIVEC older days are amazing .. is becoz of the LIFT .. Added on February 16, 2012, 2:26 pmThe newer days Mivec is ... Valve timing only .. yes .. never vtec comes with both .. timing and lift ... basically all vvt works continous ... the LIFT will only comes kicking on certain range .. (if the engine comes with the lift) This post has been edited by K3nnYkl82: Feb 16 2012, 02:26 PM |
