I think it draws about 4 Lbs of vacuum.
A Kirby vacuum engineer earns $23,872
If we install centrifugal pump to transfer liquid from tank,after empty out the tank pump is continiously running,then how much vacuum is created in tank?
The weight of a train engine varies depending on the type of engine. A diesel engine can weigh as much as 250 tons while a steam engine would be about 100 tons.
rocket what? an engine?, need to know the year and engine size.
His Steam Engine costed around £5000
That engine holds 1.75 quarts with filter change.
I use straight 30 weight. Depending on the oil pan. 6 quarts is normal.
same as engine vacuum.
18 to 21 inches.
The amount of oil needed for an Onan generator typically depends on the specific model and engine size. Most Onan generators require between 1 to 2 quarts of oil. It's essential to consult the owner's manual for your specific model to determine the exact oil capacity and type recommended for optimal performance. Regular oil checks and changes are crucial for maintaining the generator's efficiency and longevity.
Basically, the amount of vacuum in the intake manifold varies with how much the butterfly valves(either in the carby, or in the throttle body on a fuel injected engine)is opened. If you take your foot off the accelerater, the engine is trying to suck air past the partly closed butterfly, thus creating vacuum. If you are under acceleration and the butterfly is open, the engine is drawing air freely, so manifold vacuum is low. Turbocharged engines have lower vacuum because the air is force-fed, so an electric vacuum pump is sometimes used to run the brake booster.
The old "economy" gauges were little more than an engine vacuum gauge. The assumption was that if you didn't put your foot into the throttle you'd get better economy. Engine vacuum is maximum at an idle or coasting in gear down a hill. The goal of the vacuum gauge was to help you maintain as much engine vacuum as possible, in the hopes that you'd get better economy that way.
some,enough to pull blowby out an recirculate it into the intake,to much and you implode seals and gaskets,causing oil leaks and pulling debris into the engine.
In a normaly aspirated gasoline engine manifold vacuum will be 18-20"hg at sea level. you will drop approx. 1"hg manifold vacuum for every 1000' in elevation.
Vacuum leaks. Get a can of throttle body cleaner and with the engine idling and warm, spray the throttle body cleaner anywhere you have or see vacuum lines. Just a small squirt and see if the engine picks up revs. If it does, you have a vacuum leak. Fix that oen and then go spray again at others. While you are there it's best to try to locate all. The engine idles fine because the engine is not under load and your ratio of fuel to air will let the engine idle but when you press the throttle that puts the engine under load and now the engine suffers from too much air due to the vacuum leaks and it stumbles.
It wouldn't make much of a vacuum leak to cause the engine to idle at high RPM. First check for vacuum leaks even though you may still have good manifold vacuum.
A 602 crate motor typically produces around 12 to 14 inches of vacuum at idle, depending on factors like tuning and the specific application. This vacuum level is sufficient for most carbureted setups and is ideal for performance in racing scenarios. It's important to measure vacuum under consistent conditions for accurate tuning and adjustments.
