Combustion Engines

An ordinary furnace is not an engine at all, because it does not directly cause mechanical motion. The heat or expanding gases released in a furnace can be used to drive an engine, but that is a separate component from the furnace. If a furnace is used in this manner, the engine is an external combustion engine.

Hybrid cars such as the Toyota Prius or the Mitsubishi PHEV.

It is not intended for continuous working mode. So most crane works with a 40% duty cycle full-load factor. 1. lowing the hook, 2. lifting the load, 3. carrying the load, and 4. lowering the load. dixon_robert@yahoo.com I am presently researching on the most suitable motor for 35,000Kg/ 55KW full-load with vector control technology. Looking for help too....

Without going into the math, the change in speed increases the torque the motor can supply. The further the motor speed and supply speed are apart (known as the slip), the greater the torque will be.

it is very easy. u can find it in the book of machine desigh by khurmi or kannath or bhandari.

The Diesel cycle engine was named after the German engineer who invented it, Rudolf Diesel. A Diesel engine uses two principles: air gets hot when you compress it, and fuel will ignite if it gets hot enough. The engine compresses air introduced into the cylinder to a very high pressure. When fuel is injected it immediately ignites.

Essentially the first internal combustion engine was invented in the late 1600's (the specific year is unknown) by the English inventor Sir Samuel Morland. The engine ran on gun powder and was used mostly for pumping water.

In 1860 the Belgium inventor, Lenoir, designed an engine that some consider the first Internal Combustion Engine, because it ran on a mixture of air and coal dust and was ignited by an electrical spark. In 1863, the engine was revised to include a carburettor and burn liquid petroleum gas. The engine was use to move a three wheeled cart, but most commonly it was used as a stationary power plant for printing presses, water pumps, and machine tools.

You must provide details of the :-

1) Inlet air temperature

2) Fuel characteristic (LHV, sulphur contents, etc.)

3) Site elevation

4) Inlet / Exhaust loss

5) Open cycle type of GT ? Heat Recovery ?

Then the supplier will calculate for you.

Viscosity provides a resistance to a fluid being squirted out, say, between a crankshaft and a bearing journal under pressure. So measuring viscosity will be important for predicting how much protection a given fluid will provide.

It is important to maintain a vacuum in a condenser if you want it to work well.

dc motor- a basic dc motor has a stator and a rotor..

stator may consist of either permanent magnet or electromagnet. this s to produce the required magnetic field.

rotor consists of the armature conductors which carry current. when supply is given to the rotor it experiences a force and hence it rotates.

It's quite simple, really. A piston engine utilizes the linear motion of cylinders/pistons to combust the gasoline that drives the vehicle or appliance. A jet engine, however, uses a fluid (air) intake to assist in the compression of fuel. It comprises of many turbines and compression components that synchronize to force the expended fuel out the nozzle of the engine. This action creates direct thrust as opposed to the electrical energy produced in a piston engine.

Enthalpy is the amount of energy in a system and when this changes (when a reaction happens), the energy is either released (exothermic) or absorbed (endothermic) and this energy is usually released or absorbed as heat. Therefore when the enthalpy decreases, heat is released from the system making it exothermic. In contrast, when the enthalpy increases, heat is absorbed making it endothermic.

With the use of steam power, factories could be built near natural resources and where the work force was. Factories started to grow all over England and then spread to the rest of the world. Cities became more populated because the factories offered a lot of jobs. Work in the factory was more reliable than work in the fields due to the fact that farming was dependent on the weather and crops often failed. The steam engine could now make machines in the factories produce materials much faster. By the early 1800's there were hundreds of steampowered machines in the factories. Steam ran the machines in textile mills and other types offactories. In the 1820's lighter and simpler steam engines were made that could be used in small mills and stores and not just large factories.

Manual ballast water/bilge pumps are often diaphragm pumps with flapper valves. Large pumps are often positive displacement, centrifugal or moving cavity pumps depending on the amount of crud expected in the ballast.

Hot Gas Path Inspection [HGPI] is well known in Power Plants based on Gas Turbine [GT]. Normally, HGPI executed each 24000 Running hour; provided that the GT is operated in ideal condition [natural gas as fuel, base load operation etc].

In HGPI, the total path of hot gas [hot gas produced in combustion chamber] is inspected. That is

Fuel Nozzle -> Combustion Liners -> Transition Piece -> Turbine Blades

As the name states there are 4 strokes in a 4 stroke engine. Intake, when the piston draws in air/Fuel mixture. Compression, when the intake valve closes and the piston moves to the top off the stroke. Power stroke, when the compressed mixture is ignited, forcing the piston down. Last the exhaust stroke when the piston starts moving up and expells the burnt gases.

Generally speaking no you don't. There should be 6 to 8 bolts holding the two together.
Doing them together would be difficult at best. Good Luck and Remember.

Most of the online retailers such as Summit, Jeg's, and others are pretty competitive with regards to price, quality, and service.

The only thing special about the Vortec is the heads -bore and stroke should be the same on all 350 blocks. Cam is probably different though.

The cubic inches of piston displacement are generally considered to be one of the more reliable measures of real power of an engine.

If this occurs, then it means that there is a problem with you engine. A mechanic can figure out how your engine should be fixed.

Burning techniques are totally different when comparing Diesel and Gasoline. In Gasoline engines, air and fuel mixture is injected into the cylinder (in a non direct fuel injection system) this mixture is then compressed and thus temperature of the mixture increases, but not to the ignition temperature, this is why we need a spark plug in gasoline engines to start this small fire. After reaching the top dead level of the cylinder (or sometimes even before that ) spark plug releases its charge and start a very small explosion inside the cylinder head. This small fire ball propagates as far as there is enough fuel and oxygen. While this explosion propagates, the piston is being pushed down and turning the flywheel through the crankshaft. As you can see, you don't need to compress this air and fuel mixture till ignition temperature and you don't want to do it!!! This is why it is possible to design gasoline engines with short strokes. Short strokes means short reciprocating movements, which means faster rotational speed.

In diesel engines, there is no spark plug, because ( and I'm not 100% sure about that ) Diesel is not a good fuel in propagating a controlled fireball. It just doesn't work very well in diesel. Because of that, Only air is being compressed inside a diesel engine during the compression cycle. Somewhere during compression stage, diesel is being injected inside the cylinder and starts to spread homogenously inside the cylinder, compression continues and the mixture is mixed and heated up till it reaches ignition temperature. Once ignition temperature is reached, the whole mixture explodes at the same moment. As you can see, there is no flame propagation in diesel engines, the whole mixture just explodes in a single moment. And in order to reach ignition temperature you need a long enough stroke to be able to compress air till it reaches ignition temperature of the fuel. Longer stroke means slower cycle, but higher torque. This is why Diesel engines have more torque but less speed than their gasoline counterparts.

Hope this answers your question.

Okay...

The Diesel engine (named after Rudolf Diesel, who invented it) was designed to burn any flammable liquid you put in it--Herr Diesel originally intended to run it on vegetable oil. OTOH, a spark ignition engine requires fuel with a minimum amount of volatility, so gasoline has to be a very highly refined product.

The Diesel cycle compresses air inside the cylinder until it's hot enough to ignite the fuel. At that point, the injection system squirts a premeasured dose of fuel into a combustion chamber in the cylinder head. It ignites instantly. Because the flame front is confined to the little chamber the fuel's being injected into, there has to be a LOT of excess air in there. To get it, the engine is "oversquare"--the stroke is longer than the bore. (A Detroit Diesel DD15 is 5.47" bore, 6.43" stroke. It's an inline 6 engine that displaces 14.7 liters.

Now here's where it gets fun: The DD15 comes in eight different horsepower ratings, and the only difference between the eight engines is the fuel injector system--the more power your engine has, the more fuel the injector holds. (There's also a different program in the computer, but that's another issue.) Before the EPA got all antsy about diesel emissions you could take your truck to Pittsburgh Power, have them install higher-flow injectors and have a much more powerful truck for relatively little money. (You can't do that now; the current electronic fuel injection systems on big rigs keep you from doing that.)
