Tip #3: Gear up! - Riding
with low r.p.m. by quick change into the highest appropriate gear
To lower your
fuel costs, protect your vehicle's transmission and reduce emissions,
change gears as early as possible and into the highest appropriate
gear without "revving" the engine.
· Change gears as early as possible (at approx. 2000 r.p.m.)
not "rev" the engine
· Use the dashboard tachometer (next to the speedometer if
you car has one) as an 'economy-meter'
· Better fuel economy and efficiency
· Lower fuel costs
· Lower emissions and less noise
A car's engine uses the energy stored in fuel molecules to generate
mechanical power. The harder the engine works turning the crankshaft
(which turns the wheels), the more fuel is consumed. The crankshaft's
revolutions per minute (rpm or "revs") are therefore a
key to fuel efficiency and lower emissions. Low revs minimize fuel
consumption and fuel expense while higher revs increase fuel consumption,
air pollution and noise.
As you control
the vehicle's engine, you are also the manager of the vehicle's
fuel efficiency. Changing smoothly and as early as possible into
the highest appropriate gear will lower your engine's revs; benefiting
you and the environment at the same time.
have been produced since the early 1990s, which improve fuel economy
and lower emissions when using a 'low-revs' driving style (1500-2500
rpm) and without trade-offs in comfort or driving quality. The vehicle's
tachometer measures the engine's revs and can thus be used as a
terms, driving constantly in a higher gear at low revs may call
for pushing the accelerator a little harder to keep the vehicle
moving at the same speed. However, this technique is more economical
than pushing the acceleration pedal less hard while remaining in
a lower gear.
the efficiency of modern engines is better at lower rather than
at high revs. However, driving with too low revs should also be
avoided as it can lead to vehicle 'shake'. Using the appropriate
gear will keep the engine run smoothly.
Gears do not always need to be used in strict numerical sequence:
skipping gears (up or down) can be an option depending on both the
speed and terrain. Driving at low revs also warms the engine faster
and allows an optimum temperature to be reached earlier, which also
extends the life of the motor.
this greener driving style lowers noise levels. One single vehicle
at 4000 r.p.m, for example, is as noisy as about 32 vehicles at
Driving at low
revs means changing gears between 2000 and 2500 rpm. If your vehicle
is not equipped with a tachometer, the following list provides some
gear: to get going (one vehicle length)
· 2nd gear: up to 25 kph/ 15 mph
· 3rd gear: 25 - 40 kph/ 15 - 25 mph
· 4th gear: 40 - 50 kph/ 25 - 30 mph
· 5th gear: 50 kph+/ 30 mph+
