I find it amazing how many things are stuffed inside a car. Engine itself, transmissions, compressor, radiator, batteries, electric motor for starting, alternator for electricity production, radiators, brake enhancers, differentials, torque convertor and many other things. All have to work in tandem and they often do for decades without fail.
In a very similar fashion, the AC system or split system heat pumps work for cooling or heating your homes. As a mech engineer, it's nice to see how it is implemented in cars. 😊
In idle, the engine runs at a lower RPM, which means the compressor operates at a lower speed. condenser fan is typically the only means of dissipating heat from the AC system. but this is not as effective as the airflow generated when the vehicle is moving. As a result, the AC system might struggle to cool the cabin as efficiently when the vehicle is stationary. This can cause the AC to take longer but not harder to reach the desired temperature.
Heating is very basic. Heater core is located in HVAC box. The heater core receives hot coolant from heater hoses (plumbed to the radiator of the vehicle). It uses blend door motors to close off this heating circuit when the ac is selected and turns the heat on when it goes the opposite way. This can be fine tuned by selecting desired temperature on climate control so it’s not merely a On/Off motor, it has many positions.
TELL ME is it normal to drive with ac on LO and the ventilator on 2 bars , instead of putting it on automatic and just normalize the temperature slightly lower than the outside , can someone answer please
@@motoringmasters thanks for reply ! I think your video is the most logical on youtube !! , i see so many car enthousiasts with ac on LO and window open and clearly see a automatic button
Red alert check your cabin filter and just above it where mice build nest,, and there is mice feces disgusting or even a chipmunk,, and you are breathing it every time you have your air on. You must mouse proof your air flow in the cabin of your vehicles!!! Pop your glove box wide open and you can get to it, to check the filter and the area just above it,, there's usually a big enough place up in there that a mouse can build a real nice nest, so disgusting you're breathing that air. I'm going to feed some metal wire up into that space and loopy loop fashion, and fill in it in so they are not comfortable to linger or build a nest. Also I'm going to find any other areas where they can get into it and screen it off!!!!! Each vehicle will have a different air circulation system within the cabin.
@@Max-JetYea you’ll need open your car windows for a while, perhaps spray some air freshener spray. And vacuum your carpets and use wipes on all hard surfaces that may have trapped some smell. I had a bad smell in my car from the previous owner and I did this along with scrubbing and washing the floor mats outside. My car smells pretty fresh now.
Air flow is controlled by a series of dampers, flaps, and shutters that are operated either manually or automatically. In old vehicles, you manually operate knobs or levers that are connected to cables or vacuum lines. These, in turn, move the dampers to direct airflow. Modern vehicles use an electronic control unit that adjusts the position of the dampers based on inputs from the user and sensors. The user sets the desired temperature and airflow distribution via the control panel, and the ECU adjusts the dampers accordingly.
Vary informative video well explained 🎉 I have a question, what hapend when we set temperature to cold or hot in manual ac systems dose it affect car fuel consumption and how we get better mileage with ac on ? Thank you
Technically, in the engine side when the AC is turned off, the mileage is high, but practically, when the car comes and drives on the road, the mileage drops due to aerodynamic block when windows are opened. using AC can increase your fuel consumption by as much as 10% but opening the windows at higher speeds can increase fuel consumption by as much as 20%
Still the world does not know how to deal with this problem 😁 However, I have some solutions, you can try it. Place a fine wire mesh or screen over the air intake vents to prevent rodents from entering. Make sure it is securely fastened and doesn't restrict airflow. Keep your car's engine compartment clean and free of debris.
I wish I was this excited to learn back when I was in primary school. Being passionate about something(s) really do/can take you far in life. And I bet the opposite can be said too 😅.
Good afternoon, I recently installed cruise control on my 2021 Isuzu D-Max 1.9L standard model and I need a device that can program or activate it. I've tried using an OBD2 ELM327 WiFi and ELM327 HS LS USB for scanning, but they can't seem to recognize my Isuzu D-Max. Now I'm considering purchasing a dedicated device or using the TOAD program or should I buy IDSS . Could you please recommend the best option? Looking forward to your reply. Thank you for your assistance. Best regards, Tell me what do you think
@@motoringmasters it is like the organel cruise control that came from isuzu on the steering wheel and i conected to the organel conecter from isuzu For now it light up but does not work what i understand that i need to program it or active it but i could not find software for that perpuse special for Isuzu. Feel free to ask for more details. 😊
Does anyone have a solution to unlock ..cloning or remap ECU for mazda cx30 skyactiveD year 2020 ecu denso s805 18881, mb275700-9552, 12V KE124D MADE IN SPAIN...THANKS FOR ANY INFORMATION
