For a beginner, the co-ordination between clutch and accelerator is most tricky while trying to set the car in motion. The reason is that when one releases the clutch, load comes on the engine and its RPM falls, tending to stall it. To prevent stalling, one has to gradually rev the engine by gently pressing the accelerator while releasing the clutch. To our pleasant surprise, we found that one can set a diesel Swift in motion by simply releasing the clutch (without even touching the accelerator). The technical reasons for this, as I figure, are :
a) Due to high torque of the Swift diesel engine at low RPM, even at idling RPM (about 800) the engine is able to pull the car at low speed.
b) The accelerator of the Swift diesel is completely electronic (‘drive-by-wire’ technology) and does not involve any mechanical linkages or cables. As you press the gas pedal you are merely turning a potentiometer (or something of that sort) and sending an electronic signal to the on-board computer. At idling (when the pedal is at zero position) the computer controls the idling RPM, and it is probable that even when some load is put on the engine the computer tries to maintain the set engine RPM by increasing the fuel input.
Whatever be the technical reasons, the bottomline is that even for a child it is as easy as apple pie to set a diesel Swift in motion. The fact that the clutch is very very smooth and effortless also helps.
