Does the fuel consumption increase when the clutch is used?

Question

When the clutch of a car is actuated is there an increased fuel flow through the same (or different) fuel inlets?

Answer 1

Without knowing the actual make and model of the car, I can give only a general answer:

With the clutch disconnected, the engine is unloaded. Ergo, fuel consumption would be less than when the engine was producing power.

Relative to the transmission in neutral, clutch connected---I'd say the fuel consumption would be essentially the same, though there is a slight load due to the transmission gears churing lubricant.

Answer 2

Increased fuel flow is required to maintain engine speed as the clutch begins to transmit power to the wheels. Much of the art of driving a manual shift automobile is coordinating the clutch and accelerator so as to get a smooth start.

Answer 3

The clutch simply disengages the gearing so that the gearbox can shift to a higher or lower gear... thus the revs of the engine are reduced... It would follow then that fuel consumption is reduced when the clutch is engaged... its the same as putting the car into neutral...

Answer 4

when clutch is used engine diengages from the vehicle then load on the engine decreases .
but to prevent the exhaust gases in the cylinder coming back to the suction line rich mixture of fuel is to be supplied so fuel consumption increases

Answer 5

No, when you engage the clutch, you are allowing a disconnection of the transmission from the driveshaft and ultimately the drive wheels. Generally, when you shift you take your foot off the accelerator pedal, so gas flow during this time should actually decrease slightly.

Answer 6

nah. a clutch is a clutch and a throttle is a throttle.

now your ac/ compressor clutch will load ur engine and cuase some increase in fuel consumption
