Overall efficiency in internal combustion engine?
Not very.
only about 15% of the energy is used to drive your car on the road.
62% of the energy is used up in the engine itself, converting the gas to energy.
17% is used when the vehicle idles.
5% is expended in the transmission
2% is used for accessories.
What is the salary of a lecturer in Ireland with a Ph.D?
Check out the website for the University of Cork. It will provide payscales for professors, lecturers, etc. And the pay is quite high compared to London. Dublin Universities also seem to pay well.
Are 2.6 liter engines on a 1988 mighty max supposed to be noisy?
Without knowing what kind of sound you are referring to when you say noisey I can offer this. When the engine is cold and in fast idle, a vacuum activated valve opens to allow hot exhaust gas to enter the air breather. When this is taking place there is a deeper hollow sound that comes from the engine as the air breather resonates with the unmuffeled exhaust. This valve can open when it should not if the carb is not adjusted properly or there is a problem with the vacuum system which on the Mighty Max and Ram50 are somewhat complicated. This valve is located at the end of the steel tube that comes from the exhaust manifoldand up toward the breather at the rear of the engine. It connects to the breather with a rubber tube.
Is the Hedgehog Engine a physics engine or just a graphics engine?
The hedgehog engine is created by sega and it is a graphics engine that has global illumination and it has havok 5 physics engine with it so it's both.
What is scavenging process in an engine?
compressed air is sent to the combustion cylinder with the help of blowers etc.,it helps to clean the cylinder of burnt gases, this process is known as scavenging.
How do you start an engine on an engine stand?
starter motor, fuel pump, alternator, (possibly ECU) and battery need to be attached and wired up properly, be careful and make sure your engine stand can withstand all the vibrations
I have a 1993 Dodge D350 cummins diesel engine how can I get more power out of it?
bigger turbo, injectors
you can also put an HP chip in it
sorry this guy is incorrect with the chip answer dodge has a mechanical fuel pump till 1998 so if you know a good diesel mech you can have them turn your stock pump up to get more power.
but before you do any thing get a K&N air filter and put a straight pipe on it. these two will help and you should get better fuel milage
if that's not good then injectors and a turbo
Where is the connection for the EFI on an 87 crown vic 302 boss engine?
There was no Boss 302 Crown Vic; the Boss 302 was a special option only in Mustangs in the late '60's/early '70's (essentially Windsor block/Cleveland heads). You have a standard 5.0L non-High Output V8. The EFI harness in 5.0L Crown Victorias typically terminates at the rear of the engine behind and below the upper intake plenum with two large round shaped connectors. However, if you have a Police Model 87 Vic, it would be the 5.8L 352 Windsor Engine.
That depends on what you plan on using the vehicle for. If you drive with a lead foot, it may be worth it. It also depends on the state of the rest of the vehicle. If you need major body work or other serious repairs, it probably isn't worth it. You may have to upgrade the transmission to handle the extra power, maybe not. If you upgrade your HP you might want to upgrade your brakes as well! :)
Why does a 2 cycle engine carburetor spit?
Your bolts are too tight on the carburetor...over time, the carb is going to split because it's just aluminum.
How does combustion chamber size effect an engine?
if you make the combustion chamber smaller for example by shaving the heads when the sparkplugs ignites , the piston will get pushed down harder there for make your engine go faster .
In short, reducing the combustion chamber size increases the combustion ratio which increasing the explosive force of the air fuel mixture when it burns. The negative side of this is fuel with a higher octane rating will have to be used to run the engine.
Where are can I find a Subaru Outback engine diagram?
Read the first answer here:
Where_can_you_find_a_1993_Subaru_Legacy_engine_diagram
There are Haynes and\or Chiltons guide for every Subaru Legacy\Outback to 2005(US Models) you can find the specific one you need on www.haynes.com they have engine and body diagrams.
What you are after is perpetual motion, which isn't going to work. Any type of energy can be converted to heat, but heat can only partially be converted to energy. Most of the problems stem from trying to remove heat, rather than allowing it to accumulate. Heat is the graveyard of energy.
-------------------------------------------------------------------
Some heat from engines can be recovered and used for space heating. The heaters in automobiles do just that. However, more often than not the build up of heat from an engine is more than is desired for auxiliary uses, and it must be discarded to keep from overheating the equipment. Some building emergency generators can use some of that heat in a heat exchanger for heating non-domestic water supplies, but the potential for leaks precludes it from use for domestic water heating.
Could you put a gas turbine engine in a car?
Look up the Bloodhound SSC, they've put the Eurojet EJ200 turbofan engine from the Eurofighter Typhoon into it to break the land speed record.
Which one is dangerous hydraulic or pneumatic?
Pneumatic systems are inherently more dangerous than hydraulic systems at the same pressures. Most states have laws governing the construction of compressed air systems for just this reason. The ASME Code section 8 specifies rules for construction of air tanks (unfired pressure vessels).
There are less regulations on constructing hydraulic systems.
An overpressure on an air tank could result in the explosive destruction of the tank, whereas a cracked hydraulic tank would result in just a leak.
An engine specifically designed or adapted to Cranes. One such model is a Big Cummins Diesel that has twelve cylinders and is rated at 635 maybe 685 HP and is available standard on certain marques and models of heavy-duty crane. with a 200 foot boom, l50 ton lifts are well within the duty cycle!
Most likely means an engine that has not been worked on or touched with any new parts, probably remains in it's original condition.
What is back to back pressure testing for hydraulic cylinders?
Hydraulic cylinders can be tested dynamically by connecting the test cylinder with a master cylinder mounted within a rigid frame structure. Usually the test cylinder is
operated with a hydraulic power source and the master cylinder is loaded with relief
and check valves connected to the ports.
Such back to back test loads the total cylinder components including the Rod, tube,
Gland ,seals ,mounting parts etc and can reveal many parameters which cannot be seen in the conventional end to end load test. Similar set up can be also used for
life cycle test extending to millions of full load cycles.
What is oil scraper rings in any engine?
oil scraper rings are the rings on the pistons that scrape the excess oil off the cylander walls on the down stroke of each piston. this is done to remove excess oil from the combustion chamber in normal operation of an engine if this was not done you would always burn oil and forever be topping up oil in engine
If you take the governor off an engine can it mess up the engine?
Yes and no. The point of a governor is to limit the RPM's of the engine. Removing the governor in tiself does not hurt a thing, but then you run the risk of over-reving the motor and chance blowing it up. Remember, just because a motor will spin that fast does not mean that it was designed to!

What is mean by CV in thermodynamics?
CV Stands for Control Volume Only in Thermodynamics and it is a fixed region in a open systems. The region of space enclosed by The open system boundaries is called Control Volume.
The Stirling engine was invented by Reverend Dr. Robert Stirling and patented by him in 1816.
It is an engine that gets it's power from the movement of heat energy from a hot place to a cold place. It consists of two cylinders, the first one is called the displacement cylinder and the second one is the power cylinder.
The displacement cylinder has two sections, a hot section and a cold section, the piston in the displacement cylinder is a loose fit so that air or gas can pass by when it is moving, the purpose of this piston is to move the air or gas from the hot section to the cold section and back to the hot section hence "displacing it".
Second is the power cylinder containing a double acting piston that is connected to a crankshaft fitted with a fly wheel.
When the displacing piston moves to the cold part of the cylinder, the largest volume of air or gas is in the hot part of the displacement cylinder, where it will heat up and expand to a higher volume and push the power piston outwards, when the displacement piston moves to the hot side of the cylinder the air or gas moves over to the cold side of the cylinder, where it will cool down and shrink to a smaller volume and form a vacuum that sucks the power piston in the opposite direction.
