Other features include twin overhead camshafts, four valves per cylinder, multiple direct fuel - injection and a variable geometry turbocharger for high torque and a rapid throttle
response at low rpm.
This 2.0 - liter four - cylinder engine with its twin - scroll turbocharger has been revised for much improved
response at low rpm, so the car surges away from a stoplight with more authority than before.
Not exact matches
Throttle
response is not as linear as in a normally aspirated engine — you can definitely feel the rush of the turbocharger — but max torque comes on
at a
low, 1650
rpm, so it's not like you're waiting around for the turbo to kick in.
Throttle
response, seamless in most situations, is a bit sluggish when trying to rock out of deep slush, although the electric motor does boost
low - end torque (163 lb - ft
at 2000
rpm versus the conventional XV's 145 lb - ft
at 4200
rpm).
You want the turbo to spool up more quickly
at low rpm for quick
response, so the system sends engine exhaust to smaller ports to increase boost pressure.
The bottom end
response is not very spectacular, but the Brio is livable
at low rpms.
It reduces back pressure
at low engine
rpm, improving throttle
response.
Jump on the gas from a light and there is a little bit of turbo lag
at the
lower revs, but boost builds quickly and the engine has good
response above 3,000
rpm.
The engine's
response low down the rev range has improved a bit, and boost comes in gently
at around 1,400
rpm and builds nicely from 1,800
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.
When driving in four - wheel - drive «
Low,» the throttle
response softens and the idle speed increases by 100
rpm (from 650 to 750
rpm)-- providing added control when ascending and descending off - road obstacles
at slow speeds.
Proton claims that there is better
response and torque
at low engine speeds of between 2000 - 2500
rpm.
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.
Also, valve «overlap»
at low rpm can be adjusted by the controller to increase the
response of the turbocharger, providing a more immediate feeling of power.
Specific Teryx - sized throttle bodies and optimized ignition timing have maximized
low and mid-range torque and ensure excellent
response at high
rpm
Specific Teryx - sized throttle bodies and revised ignition timing maximize
low and mid-range power and provide crisp
response at higher
rpm
At low to moderate engine speeds, the entire stream of exhaust gas is directed solely through one of the two turbochargers, which improves throttle
response — the otherwise passive second turbocharger doesn't become active until the engine speed reaches 2,700
rpm or more.
With 369 lb - ft of twist dolloped on from just 1370
rpm all the way to 4500
rpm, the torquey turbo V6 offers good
response across a wide engine speed range except for a tiny bit of turbo lag
at low rpm.
In
response to complaints about the
low performance of the 144 cid engine, a 170 cid straight - 6 with a single - barrel Holley carburetor producing 101 hp (75 kW)
at 4400
rpm was released for the 1961 model year.
Although the SC weighs about 70 pounds more than other versions — bigger wheels are a factor — the 2.4 - liter, 166 - horsepower engine is terrific, with good
response at engine speeds as
low as 2,200
rpm.
An electric actuator adjusts the turbine blades
at split - second speed in
response to changes in engine loads, enabling the unit to respond with the same lightning speed
at low rpm as it does under full loads.
The turbo engine guarantees prompt
response even
at low rpm (maximum torque is achieved
at just 1,750
rpm) while Start & Stop makes it possible to cut consumption and harmful emissions levels drastically, without compromising comfort and on - board safety.
