Starting a vehicle has become a mechanical act for most drivers. However, taking a few seconds to think things through before starting up can be crucial to engine longevity. Let’s discover the best practices to adopt to preserve your car’s mechanics.
The key stages of starting
Before even turning on the ignition, it’s important to understand the different positions of the key in the neiman. For vehicles equipped with conventional key start, there are generally three positions:
- The “accessories” position activates non-essential electrical systems such as the car radio or air conditioning.
- The “ignition” position: all dashboard lights come on and the vehicle performs a self-diagnosis.
- The “start” position: the engine starts.
It is advisable to pause between the second and third positions to give the vehicle time to carry out its internal checks. This step, although brief, can prevent certain mechanical problems.
Optimum waiting time after start-up
Once the engine is running, the question arises of how long to wait before taking to the road. Contrary to popular belief, there’s no need to wait several minutes. A waiting time of around 30 seconds to one minute is generally sufficient. for most modern vehicles.
This short period allows the engine to start warming up and the oil to circulate properly through all mechanical parts. This phase is crucial, as it ensures optimum lubrication of moving parts, thus reducing premature engine wear.
Motor signals to monitor
Your vehicle gives you clues as to when it’s time to start:
- For petrol engines, engine speed (rpm) is generally high at start-up, then falls back to a stable level after a few tens of seconds. This is a good indicator that the engine is ready.
- For diesel engines, the variation in rpm is less marked, but the principle remains the same. Wait for the engine speed to stabilize before changing gear.
The importance of temperature build-up
Even in summer, your vehicle’s engine is “cold” when you start it up. Optimum operating temperature is only reached after several kilometers of driving. That’s why we recommend you drive smoothly for the first few kilometers, avoiding hard acceleration and high revs.
This gradual warm-up period allows :
– Better oil distribution in the engine
– gradual expansion of mechanical parts
– Reduced thermal stress on engine components
Risks associated with rushed starting
Starting immediately after switching on the ignition may seem harmless, but this repeated habit can have long-term consequences:
– Premature wear of mechanical parts due to insufficient lubrication
– Increased risk of seizure, especially on turbocharged engines
– Higher fuel consumption in the first few kilometers
– Higher pollutant emissions at start-up
Adapt your routine to modern vehicles
It’s important to note that newer vehicles, especially hybrid and electric models, have different starting requirements. Their sophisticated electronic systems optimally manage powertrain start-up.
For these vehicles, follow the manufacturer’s recommendations in the owner’s manual. As a general rule, a very short waiting time (a few seconds) is sufficient before setting off.
In conclusion, getting into the habit of waiting a few tens of seconds after starting your vehicle is a simple gesture which can greatly contribute to the longevity of your engine. This practice, coupled with smooth driving in the first few kilometers, will preserve your engine and potentially avoid costly repairs in the long term. Don’t forget that every vehicle is unique: always consult your owner’s manual for recommendations specific to your model.
