5 Misconceptions About Car Engines!

Ok, you promised a transmission video. I'll be waiting for it

Bladed showing off the bike every chance he gets and I'm all for it

i didnt understand why rotaries were so bad with mpg, but bro went "dorito drink too much mtn dew" and i instantenously understood why.

Even if modern cars don't need to "warm up" I still like to give it a minute to get itself primed, and then gently coast it out of the neighborhood to get it up to temp a little faster without murdering it. Its just a little mental comfort I have always kept with me.

Haven’t even started watching the video yet but rotaries are fantastic and are dead reliable if you know how to care for them. My father daily drove his RX-7 (now mine) for 12 years without a single issue. All he did was oil changes. No premix just premium gas, and drove it hard regularly

babe wake up Bladed posted a new video

1:52 The pushrod's leverage into the valves do not produce the torque, but the way its head design flows air into the cylinders, and the way pushrods have longer engine stroke. Pushrods have fewer and larger valves, and those are what helps with air velocity and fuel mixing, resulting in low-rpm torque, but it sacrifices high rpm performance. This is also the reason why pushrods are usually longer in stroke in general. Engine designers made the best use of the short rpm range of the pushrod by increasing stroke. But remember that DOHC can produce low-end torque, too, by using valve trickery such as VTEC, having variable length intake manifolds, or just having a long stroke. 2:44 Fuel economy depends on many factors, like gearing, BSFC (Brake-specific fuel consumption), and aerodynamics. BSFC is basically fuel consumption of your engine divided by power produced, and it's what separates the good all-around engine design from the rest. Aerodynamics, on a separate note, is often misunderstood. To get less aerodynamic drag, you have to have a streamlined surface ALONG with a small frontal (surface) area, and that will calculate to your effective frontal area - same principle as throwing a basketball compared to a baseball. That's why the Tesla Model X is very efficient in its range, because its effective frontal area (Cd x frontal area) is very similar to a Lotus Elise, but it will never beat the Volkswagen XL1, in terms of aero. (Edits because of spelling and clarifications)

The gas consumption has actually been a topic i'm used to talking about, I drove an '89 Century with a 3.1 v6 and some people were like "so, you must be just running to get gas every morning then" and then I'm like "nope, it gets me 18 mpg mixed and around 26 to 28 on highway" and this usually blowed their minds like "my 1.5 struggles to get that way in highway, how does that old thing gets that mileage" and usually the explanation is "well, my car can easily idle at 50 mph, and it goes smoothly to 75 when your car has to go all crazy on the revs to get there"

Your take on the Rotary engine is on point. Many non rotary engine car guys and girls think rotary engines are unreliable because they never did research on how to take care properly of the engine (eg. Checking oil regularly, premixing, redline it daily etc) and mostly bought the car (eg. Rx7) for clout and when something vital fails like the apex seals which require an engine rebuild. That’s a lot of money down the drain so they start saying rotary engines are so Unreliable

I always thought v8s were gas guzzlers no matter what, thanks for teaching me something today bladed

Yes, justice for the rotary! I had an FC and the only issues I ever had with it were clutch related. Biggest mistake I ever made was selling that car

I love that someone else actually have noticed that the politicians nowdays just make assumptions, but doesn't research the subject thoroughly and just doesn't believe the politicians blindfolded. That's worthy of a like and subscribe!

The 2 things that kill an engine are lack of lubrication, and being to cold/overheating. Engine clearances are shrunk down when cold, and expanded when hot which results in uneven wear if it goes on for too long. Always wait for your engine to warm up.

After recently putting my Mazda into the dealership for a once over I asked about rotary parts and the bloke in the service department (who also had a couple fully built rotary engines at home) said that Mazda is apparently going to try start doing what Toyota do and manufacture the parts for 12A, 13b and 20b engines along with some other parts for older Mazdas like my mx6.

Rotaries were a commercial failure but a major succes in official racing. People simply cant be bothered to properly maintain them and just blame the engine instead.

Fun fact mazda is still producing rotary parts fresh from the factory

One thing I did agree on is the waiting for oil. Yes the oil will get where it needs to go but it won’t be thin enough to get to tight clearance spots such as main bearings. Also your oil pressure is typically lower than operating temperature since the oil is thicker hence it’s harder to move which then the oil may not get to where it needs to be as it will be to heavy to flow onto certain parts of the engine other than that I agree

bruh

been watching u for a hot min. i like the way u logically explain problems in the car community and make fairly simple and understandable analyses of technical aspects. keep it up

My car is tuned. I did the tune. I went way out of my way to set the constrain statements on the ignition timing. (the minimum amount of advance) It was a lot of road testing and data logging to make this work with no misfire but using the knock frequency tables i now have a "auto tune" 87 93 pump gas tune.
