When in VTEC, since the «normal»
cam lobe has the same
timing and lift as the
intake cam lobes
of the SOHC non-VTEC engines, both engines have identical performance in the upper powerband assuming everything else is the same.
However, the valvetrain has the added benefit
of roller rockers and VTC continuously variable
intake cam timing.

intake technology.
«Our
intake -
cam timing, injector targeting and
timing of the injection events are optimized to avoid direct fuel contact on the

The «intelligent» portion
of the system is its ability to continuously vary the
timing (phasing)
of the
intake cam relative to that
of the exhaust camshaft.
With an aluminum - alloy design with dual overhead
cams and four valves per cylinder, the MX - 5 uses variable valve
timing on the
intake cam, a low - restriction variable - length
intake system, and a low - restriction exhaust system to make 170 horsepower at 6,700 rpm and 140 pound - feet
of torque at 5,000 rpm.
During cruising or other stable, low - load driving conditions, the new engine utilizes a dedicated set
of cams to close one
of the
intake valves and retard that valve's
timing, exerting backpressure on the air - fuel mixture.
Detailed changes within the engine have reduced the mass
of the VarioCam variable
cam timing equipment,
intake manifold, rocker covers and crank and connection rods.
(Undoubtedly thanks to the engine's variable valve
timing, which controls the
intake cams and their massive 14 millimeters
of lift.)
VVT - iW allows a wider range
of intake -
cam timing control.

The engine does make use
of dual overhead
cams with variable valve
timing on both the
intake and exhaust sides but does not have direct fuel injection or cylinder deactivation.
The CVT transmission and electric motor are housed together in a single unit and mated to an Atkinson cycle 2.5 - liter 4 - cylinder gasoline engine with variable
intake cam timing making 155 HP and 136 lb - ft
of torque.
The FX35 is available in two drivetrains, the RWD and the AWD, which are both fitted to a dual overhead
cam 3.5 - liter 24 - valve V6 VQ35DE gasoline engine, with aluminum - alloy block and heads, electronically controlled throttle system, and low - friction molybdenum - coated pistons that makes use
of the continuous variable valve
timing which in part optimizes the opening
of intake valves.
The AWD FX45 incorporates a 4.5 - liter (4,494 cc) 32 - valve V8 DOHC VK45DE gasoline engine with four valves per cylinder, microfinished camshafts with aluminum - alloy block and heads, low - friction molybdenum - coated pistons, titanium

Independent variable valve
timing on the
intake and exhaust side have extended
cam phaser range to 60 crankshaft angle degrees
of motion.
By using one valve per camshaft, controlled by the Electronic Control Module (ECM), each
intake and exhaust
cam can be advanced or retarded independently
of the other as engine operating conditions change, providing an exceptional degree
of valve
timing control.
