Variable CAM timing is a concept that entails changing the camshaft timing, as needed, depending on engine LOAD demands. This technology was impossible just a few years ago, due to the state of the art electronics needed. The latest Variable CAM Timing (VCT) systems are infinitely variable, meaning they have no specified settings. CAM timing can be changed or varied instantaneously across the whole range (ie. Plus or Minus 30 degrees from normal). By varying the CAM timing, the ECM can regulate the power curve to meet its own needs. On any gasoline engine, each RPM setting has an optimum CAM timing setting, depending on load. Up until a few years ago engines were set whatever the CAM lobes were machined at. With modern VCT, this relationship can be varied, also varying the engine's power curve. Most modern VCT systems do not control valve lift, but do great by simply changing open and close timing points during engine operation. See how it works here, with this superbly animated training video on automotive technology and variable cam timing (VCT).

Describes the operation of the Toyota VVT-iE or variable valve timing with Intelligence Electronic. This is Toyota's highest state of the art variable valve timing system, which uses a small electric motor/actuator to advance or retard the valve timing. By varying the speed of the motor, the system is able to change follow the CAM sprocket, increase speed to advance or decrease speed to retard. The end result is a fast acting and accurate CAM timing control system. See how it works and why.

BMW VVT Vanos CAM Timing VANOS is BMW's answer to variable valve timing. It is a combined hydraulic and mechanical camshaft control mechanism, managed by the car's DME engine management system. At the lower end of the engine-speed scale, the intake valves are opened later, which improves idling quality and smoothness. At moderate engine speeds, the intake valves open much earlier, which boosts torque and permits exhaust gas re-circulation inside the combustion chambers, reducing fuel consumption and exhaust emissions. Finally, at high engine speeds, intake valve opening is once again delayed, so that full power can be developed. VANOS operates on the intake camshaft in accordance with engine speed and accelerator pedal position. VANOS significantly enhances emission management, increases output and torque, and offer better fuel economy. The latest version of VANOS is double-VANOS, used, among others, in the new M3. The VANOS system is based on an adjustment mechanism that can modify the position of the intake camshaft versus the crankshaft. Double-VANOS adds an .... Get the whole story right here in this video.

VVT-i, or Variable Valve Timing with intelligence, is an automobile variable valve timing technology developed by Toyota, similar in performance to the BMW's VANOS. The Toyota VVT-i system replaces the Toyota VVT offered starting in 1991 on the 5-valve per cylinder 4A-GE engine. The VVT system is a 2-stage hydraulically controlled cam phasing system. VVT-i, introduced in 1996, varies the timing of the intake valves by adjusting the relationship between the camshaft drive (belt, scissor-gear or chain) and intake camshaft. Engine oil pressure is applied to an actuator to adjust the camshaft position.

1998 Supra Variable Valve Timing System Variable valve timing or VVT-i has been incorporated on the 2JZ-GE to improve throttle response and low end power, while increasing fuel efficiency and reducing emissions. As the engine reaches higher RPMs the VVT-i system reduces the amount of vavle overlap, to ensure smooth efficient power delivery throughout the entire powerband. It uses a moveable piston located within the intake camshaft sprocket, and a duty cycled oil control valve to provide a 60 degree range of intake cam timing adjustment.

Had a pal over today and it is confirmed either timed or every other stroke the exhaust and inlet are remaining open at tdc on intake. I can find tdc and there is play on tappets then after a few kicks I can also find the valves both with pushrod pressure at what looks to be 180 of the points setting thus the blowing out of carb during a stage of kick. -Possible causes I can guess: Timing gear teeth have broken off and are in situ shifted over. -the key on crankshaft has sheared or is shearing and the gear is slipping or rotating. I can back up piston to tdc with slack possible audio click from timing area in case.

This 3D Animation shows in photo realistic quality construction and function of the MAHLE CamInCam™ camshaft. This world novelty enables variable valve timing and therefore higher torque and performance at lower fuel consumption. The new CamInCam™ camshaft is an ideal solution, particularly for engines with OHV (OverHead Valve) and SOHC (Single Over-Head Camshaft) valve trains. Due to its variability, ideal intake and exhaust timing can be adjusted for any driving condition. The MAHLE CamInCam™ camshaft is the only variable valve control available in the market for this type of engine. The results are improved performance, higher torque, lower fuel consumption, reduced emissions, and improved idling behavior.

10th part of the Marine big block Oldsmobile engine build. There was some lost footage in this vid. I was just talking about how the crank spins twice as fast as the cam and by advancing the cam timing by 4 degrees the intake lobe opening event @.050" lift happens 8 crank degrees sooner. This event on this cam was supposed to happen at 12 degrees btdc. Came in at 10, advancing cam 4 degrees changed the event to 18btdc(6 degrees advance from spec).

The vehicle performance to the 2012 GMC Terrain Small SUV is discussed by Doug Smith (Production Engineering Manager), Tim Herrick (Global Vehicle Chief Engineer), Dave Poniatowski (Production Manager), and Lisa Hutchinson (Crossover Product Manager). The GMC Terrain has two powertrains available- the 4 cylinder with a 182 horsepower engine, a towing capacity of 1500 lbs and the 6 cylinder with a towing capacity of 3500lbs. Both powertrains use Variable Valve Timing, Direct injection Dual Overhead CAMs, and 6 speed transmissions which drive performance and fuel economy. The 4 cylinder engine has an Eco Button, or Economy Mode, which provides the maximum amount of fuel economy by changing the shift pattern. The Small SUV is also an All Wheel Drive (AWD) Vehicle which provides power to all four wheels when necessary. The 112"" wheel base is also the largest in its segment for ride handling reasons and provide a comfortable 2nd row egress. The 5 passenger vehicle uses a multi flex seating system to expand its cargo capacity. Using all the benefits and features available to crossovers, the Terrain also has child safety locks right on the console. For more information go to www.gmc.com EPA estimated mpg (2WD) 32 Hwy.
