3 Consigli di Guida per non Rovinare il tuo MOTORE!

Hello everyone and welcome to this new video we are in a different location I'm in the car because I want to talk about 3 mistakes you shouldn't do to keep your engine and your vehicle in good condition so I think it's a video that can interest anyone who has a car and uses it daily but before continuing with the video I always invite you to subscribe to the channel and leave a like if you like this type of video and if you want more on other topics that are always more practical let's start with the 3 things to avoid absolutely to do with an engine during daily driving the first advice I give you is not to pull the engine when it's cold what does it mean? I don't mean to pull the engine, I don't mean to go slow, to go fast not to make a highway at an adequate speed no, it doesn't mean that, it means to avoid sudden driving so you have to avoid sudden accelerations, require too much power to the engine and you also have to avoid exceeding high rpm maybe 3000-4000 rpm for a petrol engine 2500 rpm for a diesel engine this is important because when it's cold the oil has a viscosity that is not what it has when the optimal operating temperature is reached so having a lower viscosity in those moments in that phase when it's still not hot those parts of the engine that need lubrication to work are at risk, they are less protected and this is even more valid for turbo petrol or turbo diesel engines where the turbocharger and the tachometer run at very very high rpm and lubrication is essential and fundamental that it is correct and adequate to avoid breaking or inconveniences another problem that can arise is that of project tolerances in fact the metals, as we know, when they heat up, they dilate now, if the engine has not entered into temperature there will be areas that will heat up earlier than others and this creates localized deformations I'll also show you a practical example of what I'm saying comparing, showing you live the parameters of this car that I'm recording through the control unit via bluetooth then, in this screen that I show you there are two graphs, two values that I'm recording directly from the control unit with the engine just turned on in these graphs the temperature of the engine oil is shown at this moment 27 degrees and the friction of the green motor, the percent torque, 8% now, I want to see with you what happens when the engine goes into temperature then the temperature of the engine oil reaches a minimum adequate value to guarantee a viscosity, a correct lubrication that around 50-60 degrees we should already start to see some effect on the friction of the engine, the percent torque and let's see how these parameters change over time so, cold, we started from about 9% percent torque 8-9% I'll show you now, later, when the engine will go into temperature then, about 10 minutes have passed and the temperature of the engine oil has reached 80 degrees and the friction value of the engine expressed in percent torque is stabilized at 6% so, a significant difference compared to the initial 9% this behavior is also evidenced by the reading of the fuel consumption in fact, I'm reading at this moment from the dashboard a fuel consumption of 0.4 liters per hour between 0.4 and 0.5 while initially at cold engine we observed a value that was 0.8-0.9 liters per hour and therefore halved so this indicates how much the friction influences in conditions in which the engine is not in temperature the second advice I give you is to never turn off the car suddenly after long or demanding journeys so I'm not saying you have to wait 10 minutes after shopping but turning off the car suddenly maybe after a long road trip maybe at full load or because you stopped in a service area can be harmful especially with cars always equipped with turbochargers both petrol and diesel because in the turbocharger very high temperatures are reached the temperature of the oil that lubricates and cools these components on average you find a stable temperature maybe 100 degrees but there are points where the oil is much hotter there are those operating points there are those points of the engine where the oil reaches very high temperatures if you suddenly turn off the car in these moments you can verify that the oil reaches these very high temperatures because it no longer goes in a circle the oil pump stops having turned off the engine and therefore the oil risks to cook that is, it loses its characteristics that guarantee a correct lubrication to all components this in the long run can drastically reduce the life of the oil so if you don't change it if you always do the usual maintenance intervals maybe long they can seriously damage the components of the engine the third and last advice I give you is not to sink the gas that is, do not ask for too much power to the engine when you are at the regime in which this is under torque that is, if you are at 1,000-1,500 rpm with the engine almost at minimum and you require a sudden acceleration maybe with high gears and at maximum gas this thing is absolutely counterproductive don't be lazy shift gears because adopting this behavior meanwhile the engine does not provide you the performance you ask for because it goes to stall, it is under torque and all the fuel that is injected into the engine loses the need to guarantee this acceleration that you are asking for especially in diesel engines maybe we will go deeper in other videos they are controlled by the fuel injection therefore the diesel risks not to burn all the fuel correctly in the combustion chamber and therefore the only effect you get is to increase emissions and fuel consumption without getting performance and acceleration so this can also cause in turbo petrol engines especially those more pushed like the modern ones maybe with a low cylinder can cause pre-ignition problems in the combustion chamber they are very very harmful so shift gears and you can ask for all the performance you want from the engine when it is in optimal operating conditions so that's all for this video I hope they are useful tips to anyone of you who drives a car every day like the video if you like this type of content subscribe and see you in the next video bye everyone
