Why The Engine Of A Manual Car Dies Off?

A reader of this blog recently asked the following question. He or she wishes to know, “Why does the engine of a manual car die off suddenly?”

As said numerous times before, I am not a mechanic. In attempting to answer the above question, I will try to garner all my 35 years of driving experience to answer this difficult question which the reader posed.

If in my attempt to answer, should the answers given be found to be incorrect or differ from the views held by other readers, kindly do excuse me.

Mechanics, car specialists and even auto engineers are welcome to give their comments.

Why does the engine of a car or vehicle die off suddenly?

New cars, should in fact not suffer such dilemma. Car engine dying off suddenly or stalling should in fact pertain to older or second hand cars mostly.

Nevertheless, let us examine the reasons that bring about such a problem as mentioned above.

Certain car models possess good or powerful torque. Torque is explained as the pulling power of a vehicle. Some vehicles can even travel at 0 km/h, yet its engine does not vibrate.

In usual circumstances, the driver has to control a little bit of clutch to avoid the vehicle jerking or vibrating. If one is capable of understanding what torque means, he will understand that in most cars, if you are too slow to use the clutch quickly enough, when the car is travelling far too slowly, this will cause the vehicle to eventually stall or its engine dying off.

The second reason for an engine stalling is obviously your ability to control the clutch well. When a car is moving too slowly, the driver has to have good control over the clutch mechanism or else the engine tends to stall.

What is the 3rd season to explain why the engine dies off suddenly?

The engine timing might be too retarded. A slow engine may be good for consumption of a vehicle, but it normally leads to a car engine dying off rather frequently.

In mechanical terms, this means the car’s Revolution Per Minute (R.P.M) is way too slow. Ideally, for smaller c.c. cars, mechanics should adjust the R.P.M. meter to either 0.7 or 0.8.

Larger c.c. vehicles such as Volvos, BMWs or Mercedes should have its R.P.M. meter adjusted to 1.0 or even 1.2. Your mechanic should know about this. So do have your engine R.P.M. adjusted well. Failing which, your vehicle would probably face frequent stalling or engine dying off.

Is there a 4th reason which causes frequent engine stalling?

Certainly there is.

A car plugs can also contribute to this problem too. Plugs that are in use for far too long tends to be soiled or coated with carbon deposits. They might even be wet with fuel, if your car should be consuming petrol as the mechanic say. This would normally cause jerking and eventually even lead towards engine dying off.

An engine stalling suddenly can at times be caused by a wire disconnection somewhere along the electrical supply. For this, you need a good mechanic to check the electrical lines of your vehicle.

When fuel goes low and fuel indicator flashes, this indicates extremely low fuel in your vehicle’s fuel tank. Do top up your supply immediately or most likely your car engine will suddenly die off.

Finally, although not a frequent cause for an engine dying off suddenly, the battery can also be a cause towards a car stalling. A complete cut off of electrical supply of current from the battery have sometimes been quoted as the reason for an engine suddenly dying off.

The above are some of the usual reasons as to why the engine of a vehicle should suddenly die off while we are driving. Hopefully, this article answers the question posed by the blog reader.
