What helps in a car engine start-up?
This blog post will answer the question, ‘How to start a car engine?’, and cover topics like factors that help in starting an engine up, a step-by-step guide to starting and stopping a car engine, maintaining motion in a car, and how to start a car engine in cold weather.
What helps in a car engine start-up?
The components that help a car engine start up are as follows:
- The car battery
- The starter motor and the drive mechanism
- The ignition switch
- The starter relay switch or the solenoid
- The neutral safety switch
- The wiring which connects the above components
Factors that help in starting up an engine
These are the following components that help in starting an engine up.
The battery is one of the most important components of the automotive electrical system and helps to supply current to operate the starting motor and ignition system when the engine is being started.
It also acts as a voltage stabilizer by supplying currents for the lights, radio, and other electrical accessories when the alternator is not handling the load.
The starting motor
The starting motor is a low voltage DC motor incorporating a gear-drive mechanism that converts the electrical energy received from the storage battery, into usable mechanical energy.
When the circuit between the starting motor and the storage battery is completed through the starting switch, the starter motor is able to crank the engine.
The started drive gear is engaged with the ring gear at the engine flywheel, manually and automatically. Once the engine starts, the starter is automatically disengaged or the starter armature is prevented from overspeeding until disengagement is affected.
The starting motor is formed of the motor unit and the drive unit. The motor unit is made up of the following components
- Cylindrical housing
- Field coils
- Pole shoes
The drive mechanism is either of an inertia drive type or an overrunning clutch drive type.
Starting motor switches
The starter motor switches are of the following types:
- Manually operated switches
- Magnetic switches or relay switches
- Solenoid switches
How to start a car engine?
These are the following steps that need to be taken to start a car engine:
- Firstly, we need to ensure that the car handbrake is on, which is indicated by a red circle around an exclamation mark displayed on the car tachometer.
- In the case of the car having a manual transmission, the gear should be in the neutral position, and in the case of a car with automatic transmission, the gear should be in the parked position.
- The clutch pedal needs to be pressed by the left foot for manually driven cars.
- For manual and automatic cars, the brake pedal now needs to be pressed with the right foot.
- In case the car is operated using a key, as soon as the engine is started, turn the ignition on by turning the key.
- If the car has a button-operated ignition, it is important to keep the button pushed until the engine is started.
- Next, it is important to take a look at all the warning lights that are displayed on the car tachometer when the ignition is turned on. Before the car can be driven, all these lights should turn off or else that might indicate a problem.
A step-by-step guide to starting the car
Starting the car
The following steps need to be followed when attempting to start a car:
- All the doors of the car need to be closed
- The mirrors should be properly adjusted according to the driver’s position, to avoid other cars and civilians
- It is important to ensure that all the seat belts are strapped and the seatbelt sign turns off
- The handbrake must be released
- The car gear should be in a neutral position
- Choke if necessary
- Hold the steering wheel at 9 o’clock and 3 o’clock, lightly but firmly
- Depress the clutch pedal fully
- Press and release the starter as the engine comes alive, delay will damage the starter and flywheel
- Raise engine speed up to 1000rpm and no further
- Release clutch and cancel choke when the engine runs evenly
- Check all gauges like the ammeter, temperature, fuel, oil pressure, and the air pressure gauges
- After pressing down on the gas pedal, bring it down to idling speed and wait for the engine to pick up speed.
Stopping the car
The following steps need to be followed to bring the car to a stop:
- Check all the mirrors and adjust them according to the driver’s position, to avoid people and other cars while driving.
- Signal your intention to stop the car
- Take the right foot off the gas pedal gradually and avoid jerky movements
- Push the brake pedal down by gradually increasing the gas pressure
- Just before the car stops, push the clutch pedal down fully, or else the engine will stop running in case it is not done properly
- Right before the car stops, it is advisable to ease the pressure on the brake pedal as the car must be allowed to roll free for the last few centimeters before coming to a stop
- Next, apply the hand brake and shift the gear to neutral in case of manual transmission or parked mode in case of automatic transmission
- Take both feet off the pedals
- Finally switch the engine off
These are the following steps to be followed for maintaining constant motion in the car:
- First, ensure that the clutch pedal is depressed fully
- Move the gear to first gear slowly and return the hands on the steering
- Release the clutch pedal gradually till the car feels confused to move forward. Hold the clutch at that point
- Give the signal for moving out
- Check all the mirrors for incoming traffic from behind
- Take a quick glance over the right shoulder
- Keep both hands on the steering wheel and look ahead
- Keep the left foot off the clutch pedal and on the floor
- Let the car move in a steady manner for a few meters to feel up the gas pedal
How to start a car engine in cold weather?
These are the following tips that must be followed to ensure the car can start properly during cold weather:
- Turning off all electrically operated components like the heater, defroster, windshield, headlights, etc.
- Turn the ignition and hold it to allow the engine to crank for no more than 10 seconds to warm up the engine.
- The above step is to be repeated and if it fails, it is advisable to warm up the battery separately before trying again.
- If none of the above steps work, another fix includes jumping the battery.
Research has shown the various reasons why a car engine may face difficulties or might not even start.

Frequently Asked Questions (FAQs): What helps in a car engine start-up?
What are the components involved in starting a car?
The components that play a crucial role in starting a car are the car battery, the car starter motor, the fuel pump, and the flywheel.
What are the things an engine needs to run?
A typical car engine needs three vital entities to help bring it in motion. They are the fuel that undergoes combustion, the presence of oxygen that helps support the combustion, and a source of ignition to initiate the combustion process.
Why do you have to put the clutch down when starting a car?
The clutch pedal needs to be released as the gear is shifted from neutral to first to avoid an accidental starting of the car while shifting gears, the clutch basically cuts off the linkage between the engine and the transmission lines to stop the power flow and is a safety feature.
