Not exact matches
Because 99 % of the
time I will be within these
RPM ranges, the
engine will be producing more horsepower without a lot of noise or fuss, with better
engine longevity - the
engine will be producing more power
at a
lower RPM hence less
engine wear, and finally there is more instant acceleration when I need to accelerate without having to change down a gear every
time, which I would have to do in the peaky
engine.
Though the diesel's EPA figure of 23 mpg combined beats the gas model's 18 mpg average, its torque is mostly available
at lower rpms, petering out by the
time the
engine reaches its most crucial point in the powerband.
With its
low - friction valvetrain, variable valve -
timing and the latest Bosch
engine management system, the V - 12 feels awake
at last, and it spins effortlessly to its power peak, which comes nearly 1000
rpm higher than a decade ago.
Then add acetone
at a rate of six ounces for every ten gallons and run the
engine immediately in
low gear
at high
RPM (3,500
RPM) for 15 minutes and floor it on the highway six
times.
Occasionally
at low RPMs (pulling out of the driveway once, a few
times in a parking lot) the
engine just dies.
Optimal
low RPM valve
timing lift and duration settings would result in insufficient filling of the cylinder with fuel and air
at high
RPM, thus greatly limiting
engine power output.
VTEC (Variable Valve
Timing & Lift Electronic Control) is a system developed by Honda which was said to improve the volumetric efficiency of a four - stroke internal combustion
engine, resulting in higher performance
at high
RPM, and
lower fuel consumption
at low RPM.
The
engine uses continuously variable valve
timing (CVVT) and a variable intake system, which helps the cylinders breathe efficiently
at low and high
rpm.
The couple of complaints I have after a weekend are that the
engine does sound a little coarse and grumbles
at low rpm as Graham mentions above, and the transmission tuning did seem a little off as if it wasn't quite in the right gear a lot of
times.
The 2.0 - liter, 16 - valve
engine uses Continuously Variable Valve
Timing (CVVT) to boost performance, enhance fuel economy and reduce emissions
at low - mid-range
rpm.
Although the
engine gains only 0.2 kg ⋅ m (2 N ⋅ m; 1 lb ⋅ ft) torque over the VQ35HR and this torque value arrives
at a later 5,200
rpm vs. 4,800 in the VQ35HR, the torque curve itself is improved and flattened across the
rpm range via Nissan's new VVEL (Variable Valve Event and Lift) variable valve
timing resulting in better throttle response and
low rpm torque.
By pressing the exhaust sound control switch prior to
engine start, this will close the electronic valve within the exhaust system for more quiet operation
at engine startup and continue for a brief
time while the vehicle is driven with the
engine running
at low rpms.
Dual cam phasing complements the turbocharging system by optimizing valve
timing at lower rpm for best turbo response and quick
engine torque build - up
time.
Red - lining
at 7,000
rpm, the
engine — part of Honda's next - generation Earth Dreams Technology series — features an advanced new turbocharging system which incorporates Honda's legendary Variable
Timing and Lift Electronic Control (VTEC) technology to boost
low - end torque while delivering sustained acceleration.
To further broaden the power band, the 3.8 - liter
engine uses Dual Continuously Variable Valve
Timing (Dual CVVT) and a Variable Intake System (VIS) that helps cylinders breathe most efficiently
at both
low and high
RPM.
Ordinary
engines have fixed valvetrain parameters - the same
timing of valve lift and overlap whether the tachometer needle is struggling to climb out of the
low -
rpm range or screaming
at the redline.
Rated

at 5,600
RPM and 177 lb - ft of torque
at 1,600 - 5,200
RPM, the 16 - valve DOHC aluminum - alloy inline 4 - cylinder
engine includes a 10.5:1 compression ratio, Continuously Variable Valve
Timing Control System (CVTCS), spray - coated and mirror - finish cylinder bores, a variable pressure oil pump and a
low - pressure EGR system, which helps
lower exhaust gas temperature and improve knock sensitivity.

This
engine alters the intake and exhaust valve
timing to optimize
engine output across a wider
RPM range, producing high torque
at low RPMs and satisfying top - end power for highway cruising confidence.
The i10 blue, which goes into production
at the end of 2010, employs the new 1.0 - liter Kappa gasoline
engine, which produces 69 PS
