1. Some engines are advertised as “best performance” or are designed to
give best performance. A engine performs best only when it’s power band fits in
the user’s drive range. This performance depends on many factor like engine
power band, speed range, mileage etc.
To compare these engine for their performance we have to compare them on
following facts:-
Power Band:-
Power band is the range of engine speed in which it gives maximum efficiency or
it’s best working zone. Power Band of these engines are:-
Prioty order of power band data-
P1# High Power band (large band means larger performance zone)
P2# Large Powerband range(range in high rpm zone means high speed performance)
P3# High Max rpm(High max rpm means max speed of vehicle)
P4# Low Min rpm(Lower min rpm means engine start to perform at low speed)
Thus order on basis of power band:- Toyato > Swift > Amaze
In this report, a
comparison between latest
launch engines is presented
on basis of their power
band, speed range, max
torque/power, mileage,
pickup, and volume of
cylinder of engine.
Many of today’s car
engine manufacturer says
that they manufacture best.
Instead of believe on them
blindly let’s check it by
ourselves and find out
which is better. For these
comparison we selected
latest launches three petrol
engine:-
Maruti-Swift Dezire
Toyato-Btios
Honda-Amaze

Honda-Amaze 4500-6000 1500 4500 6000

2. Maximum Power:-
Max power is maximum amount of energy that an
engine can produce. High max power means high energy to convert into
use.
Toyota has highest max power then Amaze after that Swift.
Toyato’s max power decrease rapidly after performace zone but it’s power is much higher at high
speed and Amaze has little higher power band values than Swift.
Thus order on basis of power graph:- Toyato > Amaze > Swift
Maximum Torque:-
Max torque is require to accelerate the vehicle. More
torque means more acceleration and it became very necessary for high
speed racing.
Toyato gives highest torque and it’s torque value is always higher
than others.
Swift gives higher torque than Amaze at low rmp but lower torque at higher speed. But Swift gives
better torque in overall powerband zone than Amaze.
Thus order on basis of torque graph:- Toyato > Swift > Amaze

3. Mileage:-
Millage is the distance that an engine can travel with one litre of
fuel(petrol). More mileage means more efficiency of engine with less fuel
burning. It’s a very important point for economy and environment.
Thus order on basis of mileage:- Swift > Toyato > Amaze
Engine cylinder volume:-
Engine cylinder volume(cc) is another important data for
Engine comparison. More volume means more fuel mixture and more volume
to compress/Expand to mixture.
.
Thus order on basis of cylinder volume:- Toyato < Amaze <= Swift
Analysis:-
On seeing all above data Toyato shows best result but when we
Watch it carefully we came to know that Toyato has 24.98% extra cylinderical
Volume than other engines. But Swift shows better result on less volume.
It means Swift engine’s performance is better than others.
Result:-
Swift > Toyato > Amaze
