Starting A Car Which Is Already Started

[Uditha88]

Hi,

Have any one accidentally tried to start a car which is already running in idle?

you might know that it makes terrible noise.

1. what that sound really is? (Flywheel?)

2. Does this damage any part of the vehicle?

sound is starter motor drive wheel trying engage with already running ring gear (teeth around the ply wheel). Can damage ring gear teeth and drive wheel splines.

If you do it all the time then it will do harm for the flywheel ring gear and starter motor ring gear . but few times wont hurt .

It happens with me as well

has happened a few times to me... always wondered why the manufacturers never put in some control to ensure starter motor cannot be powered if the engine is already running - or is there ever a situation where you need to run the starter when engine is already firing?

Yes Sifaan,

According to research I did, All new cars has this feature.

That's if we accidentally try to restart, the vehicle automatically ignore that.

See how technology evolves & improve by eliminating drawbacks already has....

Sifaan,

There is no need to operate the starter motor when engine is running but some Automobile engine idling is not noticeable that is the reason the drivers try to start already running engine.

Some new cars has this method from the ECU disabling the starter motor when the engine is running.

All high powered Generator Diesel Engines had this method from 1970S one day every utility Automobile Engines will have this system what you question.

It is a very simple system you have a speed censer not to activate starter motor switch when the engine is running on its power then you cannot operate the starter. As all ways speed of idling engine is little higher than before you operate the starter motor.

i don't know about new things present to prevent this. But few ford escorts of 70's I had and a friends cortina i drove had this ignition switch which only allows one turn to start position. If you want to fire up starter motor again you have to move to I th position or off position. Beames bit*h if engine refuses to start at once. But its good to prevent the said damages.

I wish technology in vehicles could actually evolve a bit faster. In our lifetimes, we've seen mobile phones evolve from bricks with 12 buttons and miniscule screens to ultra-small, highres colour screen, touch screen devices with wifi etc.

even if don't care about frivolities like customizable ring (horn) tones, what about the fact that for 100+ years, the automobile industry hasn't been able to find an alternative for the most dangerous part inside the car - the steering wheel? (I recently saw some pics of (I think) a porsche concept car with a joystick; but even if that is true, it's still far from mass production reality)

sifaan why is the steering wheel considered a dangerous part?????????

heard the starter motor is very bad for fuel consumption...removing the starter motor will get you 1kmpl more!

[harshansenadhir]

in terms of safety, in an event of an accident.

I thought the most dangerous part inside a car was the loose nut behind the steering wheel...

[harshansenadhir]

I thought there's no impact of the starter motor, towards fuel consumption as it isn't engaged with the ply wheel all the time

harshansenadhir,

You are correct Lucas and Delco Remy Ignition switches some had this option there was a lock on the switch in build so that lock will lock the starting position when you operate the starter once next time you have to completely off the switch to operate the starter motor.

There were no replacements for the said switches as they were assembled by a different party on order to lock the starting position switch cam.

because it's dangerous to get thrown forward in a collision and have the steering wheel smash your head or chest, even if seatbelts and airbags help to mitigate this

[Sifaan]

depends if you are referring to the most dangerous for the driver, or most dangerous for passengers / other cars / pedestrians

Master Don,

Removing the starter motor only reduce the weight of same that will save some fuel. Fuel saving for starter motor weight I think it is negligible.

Then you have to use the stating handle to start the car engine or push start the car.

Like good old day cars had the engine cranking handle in front of the car in build with a spring to push back as soon as the car starts like present day the two wheel tractor has De compression of engine with a small handle on the engine head operator has to turn number of revolutions and release the Engine De compression liver to start the engine

This above said De compression liver allows the engine to turn without compression build up on the Cylinders.

harshansenadhir,

Starter motor engages only at the starting point of the engine it is never full time drive with the engine.

There was 1930 model Morris Cowley which had full time operating Dynamo motor one unit which works on a chain drive. when battery current is inter connected to that unit the engine starts when engine starts up battery get charged with that unit acts as a Dynamo.

I remember in 1970s we had some small motor cycle and a three wheeler Italian build with the above said Dynamo and starter motor in one unit single Cylinder engine.

But Sylvi, dont you think MasterDon makes a good suggestion there as removing the starter motor will even reduce battery consumption? It will even help keep the environment clean. and one part less that could go faulty. Dont you think the cranking handle like the good old days is a feasible alternative?

By the way, even I had some liver today. Didnt compress much, but digested pretty well!

jeeze dude...it was just a joke coz of Uditha88's obsession with fuel efficiency(no offense intended Uditha).

My TC has one of 'em crank start things...nearly broke my arm because of the recoil once...never again!

Top gear,

If you take off the Starter Motor and have the starting handle you can have a less capacity (Ampere) Battery as requirement only for other Electrical equipment in the Vehicle can be 20 Ampere Battery when engine is running the Alternator will compensate the drain of the battery charging will be regulated by the Electronic regulator for the current demand of the vehicle.

Yes it is feasible good for the health Cranking the engine but today every thing is made for the comfort of the driver. I cannot comment about the Environment clean matter.

I understand what you pointing at my spelling mistake I have told in my previous posts I am very fast typist due to that I make mistakes.

LIVER is a part of the human body. I wanted was to say LEVER on that post. Insted of E I have typed I on that post.

I appreciate your post. Instead of humiliating me for my spelling mistake like in the past by one member you interpreted my mistake in Biological language which is very great of you.

Thank you for pin pointing that mistake of mine. I only want to share my Knowledge.

Master Don,

You are correct.

MG TC some had If I am not mistaken the Starting handle but they all had Lucas Starter motors if the Engine timing is little too advanced you will get a back fire from the engine then the cranking handle will turn to anti clock which effect will come to your Wrist my father have had number of times treated for that problem he had told me in 1920S to 1940S Magneto Ignition engine cars which is no more even Motor cycles had the same problem on the kick start peddle it used to throw your leg out of the peddle when old BSA and most Magneto motorcycles had.

Unkel!! where were you? we missed you

Removing the starter motor only reduce the weight of same that will save some fuel. Fuel saving for starter motor weight I think it is negligible.

Unkel i am also thinking of removing the Power Steering unit and AC compressor to reduce weight. I initially wanted to remove the engine head and 2 pistons (dont wory there are 2 more inside) to cut back on weight? good no? AC i can do without cos i can manually keep a newspaper inthe car and fan myself and cool me when waiting in traffic. Power steering also ok, because i always travel with a friend and i can ask him for a support, like u use the liver. Engine head i think is too big and bulky. Can i get a baas to make me one in fiberglass?

Like good old day cars had the engine cranking handle in front of the car in build with a spring to push back as soon as the car starts

They just dont make cars like they used to make them back thn.. now cars are like match boxes.. they crumble into peices as soon as something comes and hits it... not solid at all also..

Ya. I understood ur intend. And also saw how others misunderstand it & killed there valuable time to reply it. But I have rather better solution for better fuel economy. "Removing Petrol Tank"

LoL abt u Don Don. Damn Joker u r....Keep it up....

[Watchman]

dont worry.. we know M_D was kidding around not everyone is as sense-less like sylvi.
