Hi!
Winters has now commenced. My question is that when taking the car in the Morning, what should be the first step.
Should we start the car and immediately drive? will it not effect the engine.
The best is to keep the engine idle for quite some time till the temp is reached to a normal level so that the engine is not effected and oil reaches all parts.
If we will start the car immediately it will effect the engine and will put more pressure and FE will reduce.
Please comment.
Start your car,race a little & you are ready to move. The engine is not at all effected & you don't need to worry about the oil reaching all parts too.
It will also affect the engine life and will give the low FE.
This is another wrong statement.If your engine is built to handle so much of heat why do you think the cold will affect it ? If you are still in a doubt,people from the north side (Kashmir,Punjab,etc) have similar engines as on your car & the temp there is way to low. So stop worrying & enjoy driving.
The car's run fast in the morning as the air temp is low.So just floor the throttle.
For Carburator Engines:-
First press your accelerator pedal 3-times,keeping your gear in neutral.Then pull up the choke knob and turn the ignition key on and then crank.If the engine dont start press down the choke knob immediately.Then again after 5-7seconds pull up the choke knob and turn the ignition key and crank.it will start.Keep it in idle for 5-10mins depending on the temperature.The lower the temperature the more you have to keep the engine in idle.After the specified idle time period,press down the choke knob down and hold your accelerator and press gradually to check whether the increase in rpm is gradual or not.If there is sluggishness in gradual increment of the rpm then again pull the choke and leave it for few more moment.But please dont move your vehicle just after the first ignition without idling cause if your acceleration is sluggish, you wont get best performance from your car till it overcome the sluggishness, which will be totally gone after idling.
For MPFI engine:-
Dont press the accelerator(as usual) and turn the ignition to on position and wait for around 3-5 seconds until the fuel reaches the injectors.Then start the engine.and keep it in idle for 5-10mins depending on the temperature.The lower the temperature the more you have to keep the engine in idle.Then after the specified idle time period,press the accelerator and check whether the increment in rpm is gradual or sluggishness is there,keeping the gear in neutral.If there is still some sluggishness then again keep the engine on idle for few more seconds or else you can move the vehicle gradually.
Hope it help petrol vehicle owners/drivers.
CARB CAR's -
1)There is no need to press the accelerator pedal 3-times.
2) Pleas don't hurt you engine by keeping the choke open for 5-10 min's.
The choke is provided to increase the petrol flow just to start the car.As soon as the car starts,just revv it and push down the choke.Never use the choke for more than 1 or max to max 2 min's.It causes more flow of petrol,nothing else.
3)There is no need to press down the choke if the car doesn't start in first time.The choke is nothing but a small mechanism connected to the carb which on pulling lets more more fuel in the engine.
So if the car doesn't start in the first go no need to push back the choke.Let it remain & try to crank again.
{Have owned a carb zen,used to start it at DOT 7 am (for collg) without choke,did it for 1 sem (6 months) no bad effects.Used to move the car with in 5 seconds of starting & i am sure you can guess my driving style]
MPFi Car's -
Dude you got to be kidding me, 5-10 min's of idling for a MPFI car ? Why ?
Whats wrong ? Just start the car & move it.Don't care about the temp,etc in a MPFi car please.
One's the mpfi cars start they never experience the sluggishness in the RPM thing.(ECU controls it)
MPFI - MULTI POINT FUEL INJECTION - Controlled By ECU (computer) You don't need to worry at all. Start the car & you are read to fly.You drive it in a sane way or like a crazy psycho doesn't matter to the engine at all.
Well, if you press the accelerator more than once during the day and more than 3 times before cold start in a carb engine before starting during your drive, excess fuel will get in the chamber which will prevent the engine from starting.
The same way, for an mpfi engine if you press the accelerator before starting the engine, excess fuel will accumulate and engine will not start.
The engine gives a dam about you pressing the accelerator in a carb or mpfi car before cranking the engine.No matter how many times you do it or nothings gonna happen.Even if you do it after turning the key to acc mode or even further it where all the engine lights glow NOTHING IS GONNA HAPPEN.
Because until the you crank the engine,let the cam shaft revolve which in turn opens the intake valves & THEN THE FUEL AIR ENTER THE ENGINE.
Just make sure you don't press the accelerator during cracking(starting) the engine because the min amount of air & fuel mixture to enter into your engine is decided by the ECU & its perfect taking consideration of the temp,etc.
Where as in a carb car there are no computers checking the temp & the amount of air-fuel that needs to enter the engine during could start so you can press the accelerator while cranking (Starting) so that you put in more fuel & air mixture.
