if total quality is the engine, is communication the oil that keeps its running?

this statement is really justified. in present world communication is considered as the key factor of the success for any concern. ineffective communication or no communication  \nstops the smooth running. if we wont share ideas, information than things gonna stand where they are.\n\nthats why funda of team spirit is on high as in team proper channel of communication can be made effective.

There is a gear, at the end of the cam shaft, that drives the distributor shaft. On the other end of the cam shaft, is a gear that is driven by a chain, or belt, that is driven by a gear on the crank shaft. They all work together to 'time' the ignition of the fuel/air mixture compressed in the cylinder. Read 'Chiltons', refer to your car's year and model.

No! There is no natural dirt in an engine. The reason oil gets dirty in an engine and has to be replaced is, over time while driving your vehicle, dirt gets sucked into the motor and the air filter can not stop it all from going into the motor, and it accumulates in the oil.That is why your motor oil gets dirty for the most part.The oil filter is also not able to trap all of the dirt. Another reason to change it is, over time the lubricating qualities get broken down and it is not able to keep the engine poperly lubed.

Depends on what you mean.\n\nDoes an oil's viscosity change over time when used (for example, in an engine or gearbox)? Yes - although the changes aren't necessarily predictable. Theoretically, as oil is used in an engine it will oxidise and the oil will thicken, it will also pick-up carbon from the fuel combustion and will thicken, and the engine will "boil off" light ends in the oil causing it to thicken. However the oil can also absorb unburned fuel which can - in the short term - cause viscosity loss. Also, if the oil is a multigrade oil with polymeric viscosity improvers the engine can "shear" the VI improver and thin the oil. So, an engine oil's viscosity in use is dependant on a balance of these effects and is, therefor, dependent on its chemistry, the engine's mechanical condition, running conditions, fuel type, etc.\n\nGear oils are a little easier to predict - they will thicken over time in use as the oil oxidises. VI improvers are normally not present and don't interfere.\n\nIf, OTOH you are asking whether the viscosity of an oil stored in a bottle or drum will change the answer is "no" -  not in any way that will make a diffence to its use. You could store a gear oil or engine oil for 20 years and not see a substantial change - the oil may oxidise a little bit but the effect on viscosity will be negligable and, in all liklihood, the oil will have antioxidants added to it to block the oxidation anyway.

It's not.\nIf you're thinking only of internal combustion engines, they can be built to run on a number of other fuels...\n\nKerosene/diesel, most of the alcohols, pretty much any volatile liquid or explosive gas -  hydrogen being a favourite...   (If I recall correctly, somebody once built an engine that ran on peanut oil...)\n\nIn practice, petrol/gasoline has been readily available for some time and, until recently, there was little incentive to develop efficient alternatives.  That may change.\n\nThen there's electrical propulsion, steam, direct-heat engines, and a bunch of other ideas waiting to be looked into

It’s a pressure system, using pressure the gas or oil is moved through the system, that’s why you cant have any leaks, otherwise you lose that pressure, and gas and or oil is pumped through the system properly. Also why you have an “Oil pressure” light or picture etc, on the dash, its moved by pressure, and the loss of pressure can lead to major problems.

well um depends on where ya live, where you take it..what kind of maintance you want done...there are alot of things to be maintained on a car...not all of them done at the same intervals...

One very important application for viscosity that affects much of the world is the rating of engine oils.  For example 10W30 engine oil behaves as though it has a low viscosity (10) while cold during startup but thickens due to the action of special polymers when hot (30).  This increases the flow of cold oil improving initial lubrication while reducing engine wear.  The specific oil viscosity grade selected may depend on the season and the minimum temperature expected (especially where bitterly cold).  This can be an important safety consideration allowing a sure start when the battery exhibits minimum power, preventing people from being stranded in the cold.  When I worked at Brookfield Engineering (long ago) they shipped viscosimeters all over the world for use in chemical plants including paint factories.

Do what you say, say what you think. \nIntegrity is the one most single quality to a sustainable business.

Simple. An engine makes its own power from fuel (usually internal combustion) and a motor takes its power from an external source (usually electricity). Regardless of what others here are saying.

The answer to your question depends on where you are located and which fuel quality standard you are working against.\n\nTypical diesel fuel quality looks at :\n\nDensity\nSulphur Content\nFlash Point\nViscosity\nCorrosivity (Cu) \nStorage Stability\nBTU content\nWater Content\nAcidity/Alkalinity\n\nThese tests will all be relevant for biodiesel.\n\nDensity is important because it is a relative measure of fuel energy content - although this is better defined using BTU.\n\nFlash Point is important as it denotes both the relative safety factor for the fuel and, in the case of biodiesel, relative residual methanol content. The flash point should be > 60C \n\nSulphur content - regulated depending on local laws - usually < 50ppm. Shouldn't be a problem for biodiesel but may be indicative of residual sulphuric acid if using a two stage transester reaction.\n\nViscosity - important because the fuel system needs to have a relatively low viscosity fluid to operate efficiently. High viscosity is undesirable and viscosity can be affected by choice of base vegetable oil / fat used.\n\nCorrosivity - Important  as we don't wish to corrode fuel systems! Also important because if the fuel is corrosive to copper, the most common test metal, it is also likley to have a low stability. Copper ions catalyse the degradation of many fuels and many fuel systems contain copper.\n\nStorage stability - Commercial fuels may be stored for indeterminant amounts of time - a minimum storage stability of 12 - 18 months is desireable.\n\nBTU Content - a measure of the energy in the fuel.\n\nWater content - linked to stability and corrosion but also just not something desireable in the average fuel system.\n\nAcidity/Alkalinity - probably more a question of residual alkalinity in biodiesel as a measure of how well "washed" the fuel is. Probably better to measure Na/K ppm, but this isn't as easy for the "backyarder".\n\nHow to test :\n\nYou can do Density, viscosity and flash point by relatively simple modifications of the ASTM standard tests. Density is by hydrometer, viscosity by flow comparison with standard diesel and flash point by an "open cup" flash test (long match / small beaker).\n\nThe other tests are more difficult and require a full lab.

No. It just wastes more gas, builds up carbon deposits in the cylinders quicker, and tends to make the engine an oil burner.  There are many possible reasons why his is faster, but worse than optimum combustion isn't one of them.

oil do my best to answer this one

There is not sufficient information to calculate efficiency. \n\nFor an engine you need the energy input and the energy output. Energy output divided by energy input times 100 gives you the efficiency. \n\nThe amount of fuel and its energy content will take care of the input. The output requires a dynamometer or some other means of measuring the energy output at the engine shaft

The other guy hit the nail on the head with cheap.  In its crude form, oil can carry a lot of energy and is relatively stable.  Spills are critical though.  We are "married" to oil in a sense because we have a network of pipelines through the country.  Some of the other advantages of oil are the number of by products that we get from oil.  piratically the whole interior of your car is made from petro-plastics, as are shopping bags, laptops, etc.  So you get a lot of bang for the buck.
