The wide gear ratio spread helps maximize fuel economy by helping
lower engine rpm in city and highway driving.
Together with changing the air intake filter, all of this helped the car run much better, especially when being driven at or accelerating out
of low engine RPM.
The fact that the oil pressure drops when slowing down or stopping would suggest that the oil pressure is lower
at lower engine RPM's.
In this application, the transmission's final gear ratio is 4.69 - percent taller than the Accord CVT on which it's based, to allow
for lower engine rpm while cruising.
This state - of - the - art unit has optimized gear ratios to
maintain low engine rpm during high - speed driving, which maximizes fuel economy and minimizes cabin noise.
Ride more comfortably in your vintage vehicle with our overdrive transmissions that enhance drivability by
enabling lower engine rpms at highway speeds.
The overdrive
gear lowers the engine rpm but customers often change to a numerically higher axle gear ratio to drive at modern highway speeds.
This Ti - VCT engine, delivering at least 280 horsepower and E85 compatibility, is mated to a unique six - speed automatic transmission that combines lowered initial gears for improved off - the - line acceleration and higher gearing for improved efficiency at
lower engine rpm when cruising.
The result is up to a 15 % increase in
low engine rpm torque, a 7.5 % improvement in fuel efficiency and a 10 % reduction in C02 emissions.
The new engine is fitted with direct fuel injection and a variable vane turbocharger for more boost
at lower engine rpm.
That would explain it; at
low engine RPM the oil pressure drops enough to turn on the light.
Initially, I started doing this to my first car, where the motor mounts were worn and leaving the car in D while held still with be brakes would result in the entire car shaking (due to
the lower engine RPM).
If you have a battery that is on the verge of going bad and is only at 79 % then what can happen is you could have the other electrical loads cause erratic operation at
lower engine rpms.
Generally speaking, a lower - number axle ratio offers better fuel economy and
lower engine rpm for a quieter ride, while a higher number enables better acceleration, as well as climbing and towing ability.
For example, you have a choice of final - drive ratios, with the lower - number axle ratio offering better fuel economy and
lower engine rpm for a quieter ride, while the higher number enables better acceleration, and climbing and towing ability.
... Based on Formula 1 technology, the Garrett turbo used moving vanes to manage the amount and speed of exhaust gasses passing through the turbine, causing it to act like a small turbo that spools up to boost quickly at
low engine rpm, thereby reducing turbo lag.
For example, twin balancer shafts positioned at different heights result in optimized vibration absorption, while a centrifugal pendulum absorber integrated in the dual - mass flywheel brings a noticeable reduction in irregular running at
low engine rpm.
The transmission efficiency and gear ratio spread enable spending more time at
lower engine rpm and the use of numerically low axle ratios further improve highway fuel economy.
XE packages improve fuel efficiency by
lowering engine rpm at a given vehicle speed, a concept Volvo calls «downspeeding.»
This reduces exhaust back - pressure at
low engine rpm, allowing the energy of the exhaust gas pulses to be utilized as efficiently as possible.
It is ideal for having something stronger than the car's factory transmission and for adding overdrive to
lower engine rpm at highway speeds.
There is strong and sustained acceleration thanks to plenty of torque even at
low engine rpm, a smooth response that minimises gearbox use thanks to the flat torque curve typical of the best modern petrol engines, and an engine note that is engaging without ever becoming intrusive.
And maximum torque can be accessed at only 1900 rpm, dramatically improving driveability at
low engine RPM.
The transmission efficiency and wide ratio spread improve fuel economy by operating at
a lower engine rpm in both city and highway environments.
Compact and lightweight, the transmission is designed to withstand maximum torque values up to 350 N · m. With six gears, the transmission is designed to operate at
a low engine rpm to provide maximum fuel economy.
The mono scroll housing design helps the turbo build boost even at relatively small throttle openings and
low engine rpm.
This was achieved through a combination of high compression ratios, improved exhaust design, and by a new style of turbocharger that allows the turbo to spin faster at
lower engine rpms.
