Engineering Explained

How do cars work? It's a simple question, without a simple answer. That's what this channel is for! You could search the web endlessly for consumable information, or you can watch my simple to understand videos. I'm a graduated mechanical engineer with a passion for cars, and my goal is to help other people passionate about cars learn how they work. Hope you find my videos enjoyable; feel free to ask questions! \n\nNew videos every Wednesday.\nJason Fenske - Channel Owner - Engineering Explained

    Idk about you guys but I drive a manual 2006 mustang gt (it’s obvious fuel injected) and when I start this thing and just try to take off I can feel the difference in driving it drives completely different when its not warmed up and for that reason I will always warm up my car

    Had a 2015 FR-S for 4 years, fun car. Did the UEL header and tune to wake it up , must do mods for these cars! Traded it in for a 2019 ND2 Miata. Although power numbers are similar the Miata feels faster. Not tempted to do any mods beyond the Borla axle back I added which is a good thing because the aftermarket has yet to come out with any type of FI for this car. Problems cracking the computer I’ve heard.

    Guys, I just love the way you make it look so simple regarding the difference in both areas, but more important is that you both realize how much both areas rely on each other, the just graduated is supported by the technical expert and technical expert learn some methodology as well!

    I get the fact that the young guys want the turbos -- and bells and whistles and gadgetry -- but at 50 I drive my cars to 200k and I LOATHE turbos. Many more problems and no longevity without expensive bills. The Ascent is Subies least reliable car...

  • Brenton Riggs

    Why doesn't the second equation take into account the pressure drop? It's still there, just not figured for... The twin scroll turbo is still only splitting the pressure that a standard turbo would see in half, with each "scroll" getting exactly half the pressure, right? Please someone teach me, or correct the equation and then convince me. I mean, with a compound turbo setup, the full amount goes through the small turbo to build boost quickly, then the full amount gets diverted to the big turbo (at higher rpms). That makes sense to me, but sending half and half throughout the entire rpm range seems to me like it would cause both turbos to operate far outside of their efficiency range.

    Am I the only one wondering how that genius is able to remember every result before writing it? I have a question! (I have plenty of them if someone has time and knowledge to answer) having a heavy back provides a better start for rwd (and probably awd as well). But does that mean having a heavy front helps braking? I mean: more load on the front, front tyres will only block at higher braking force? Is this true? Thanks in advance! Btw, Jason you made me understand so many things about cars. I love science and now even more. Keep going!

    I like how the free valves are tied to the turbos no cams and also the ability to tune the valves electronically for air flow wonder how a similar concept would work for a propellor airplane the HAL effect type ignition is a big huge deal in older engines as well as new ones just to compare concepts thank you nice presentation stuff like this has a way of getting around.:)

    Where and how are you coming up with this gibberish? I've been driving manuals and taking them apart for 50 years. And I have ALWAYS used the shifter as a hand rest. There ISN'T ANY EXTRA WEAR...damn dude, they aren't made out of plastic. Of course, your driving a Z, so maybe it does have a Lot of plastic inside that trans of yours...but America Cars use STEAL in yeah...maybe, just maybe after about 300,000 miles you might start to see some wear....

    This video is not about when to shift, it's about what gear to choose going with a steady speed. Your conclusion are wrong. If you whant to save fuel while acceleration , just accelerate to the target speed as fast as you can using less gears and higher revs, then shift to the highest gear you can use. In that case your acceleration period will be very short. Average BFSC will be lower then if you accelerate with low rpms and use short shifts. It's good only for cheating on econorms.

    Premium gasoline is called premium for very good reasons. Premium is always better than regular 87 octane gasoline. Premium gasoline keeps the car injectors clean and functioning well for life, the car gets about 10 to 15 more horse power, the car gets better mpg, the car is more agile when accelerating fast and the best of all, you don’t have to keep fixing your car for unnecessary repairs. 87 octane regular gasoline is junk, the very minimum for a car to run; over time, it clogs the injectors, ruins the valves, ruins the catalytic converter, ruins the muffler, over time the car looses horse power (if your car had 130 horse power when new, over time the car will have only like 80 horse power or less), when using your A/C on the summer and going up hill the car starts making a horrible valve noise and has no power going up hill. Of course there are people that not notice any difference because are cheap by default and they will never admit that premium gasoline is better over regular 87. Of course over time they end up paying more money on unnecessary repairs and services like cleaning the fuel injection system, replacing bad injectors, valve adjusting service, replacing a catalytic converter, replacing a muffler, not passing the smog check and many other problems caused by simply using a cheap fuel. I have never had a problem of the ones mentioned above with all my cars, I always use premium gasoline. I compare this as eating a $25 rib eye steak in a nice restaurant vs eating a $5 hot dog in the street. Both may fill you up equally but the rib eye steak is way much better than the $5 hot dog.

    Hi There very informative.. But here's a loaded question. No doubt that Gasoline has much much higher energy density than batteries. But when you compare Energy Consumption on both Gasoline Engines vs Electric Motors and consider the efficiency of Gasoline engines. What percentage is used from the total KJ of Energy is actually turned to tractive work.. aka turning the wheels, and measure that from the engine through the drivetrain. Now compare the same losses relative to the Electric car. I'm totally curious, pretty please.

    Would rather the flat 6 subaru engine as an option than a turbo. I like turbo subarus, but having now helped with 2 complete engine rebuilds for turbo subarus, I am convinced that the stock subaru turbos are too prone to early failure.
