STARTING & DRIVING
It can be observed from the characteristic performance
curves of petrol and diesel engines that..........
The low end torque of the diesel engine is less as
compared to petrol engine, at same engine speed.
The maximum torque of the petrol engine is at higher engine
rpm than of the diesel engine.
The response of the diesel engine to acceleration and
deceleration will always be slightly sluggish than the petrol
engine due to “Component Inertia” and the combustion
process.
Therefore while driving a diesel car ensure that............
While releasing the clutch pedal for marching from stop
position give little more acceleration than the petrol engine.
To avoid deceleration jerk, synchronise the clutch release with
engine speed.
While shifting to higher gear, accelerate the engine to higher
rpm (3000 to 3500) than max. torque rpm (2500) to avoid
the jerk or stalling.
Shift to the lower gear as soon as engine rpm drops to

(2000 to 2200) rpm which is less than max. torque rpm
(2500)
Apart from the above practice, following are a few good
habits......
Always start the car from halt, in the first gear.
Switch off the AC and all other accessories while starting from
rest.
Do not ride the clutch or drive with half clutch, instead use
parking brake, if required on gradient.
Have engine properly tuned, particularly for antistall setting.
Maintain the engine and fuel system properly.
Maintain correct tyre pressure.
