To fully understand this is to know the term Supply and demand ... Supply and demand is when you have a lot of one thing and there's not a lot around like oil, gold or sliver etc ... the more people want the oil compounded by that lack of it will raise the price of it ...

For the most part, our gas prices do not follow any sort of documented pattern. While it has been great watching prices plummet over these past couple of months, this has less to do with demand, or supply because OPEC is a protected cartel. They set the price and we pay it, or go without gas. The problem, however, is when they keep the price high people start talking about alternative sources of energy ect, like we saw during the election. This is bad for them because they rely on our dependency for oil. Consequently they begin to lower the price, but that's not to say they won't raise it again once they feel our memories have been erased, ect.

Gas prices effect families because as gas prices go up the economy is going down. This causes job losses no businesses and you may even have to give up some of your freedom to help your families.

A gallon of gas cost 15 cents in 1944. It was only 35 cents in 1970 which means, adjusted for inflation, it was cheaper than in 1944.

Also the price in 1944 was kept fixed by wartime price controls since the beginning of the war and very heavily rationed. If people needed to do any extensive traveling by car in 1944 they picked up as many hitchhikers as they could and if the hitchhikers had any gas ration coupons in their ration books the driver made use of them too.

It'll probably be OK. As long as there's enough diesel to properly lubricate the injection pump then no problems.

Because the fuel is ignited by a spark plug rather than by compression as is the case with a diesel.

A diesel engine is an internal combustion engine which uses the heat of compression to ignite the fuel/air mixture in the third stroke of the 4-stroke cycle, while the petrol engine is an internal combustion engine which uses an electrically-generated spark system to do the ignition.

Diesel engines have a higher efficiency compared to petrol engines. In simple terms this means diesel engines can give 50% or more miles per gallon than petrol engines.

There is no difference. Petrol is just another name for gasoline. MPFI just means Multi-Point Fuel Injection. A petrol (gasoline) engine can be MPFI or it can have a carburetor. It can have many different ways to get gasoline (petrol) to the cylinders.

About 39 per cent. The Gibbs free energy for gasoline (petrol) is about 45.7 MJ/Kg, and the amount of mechanical energy obtained is about 17.6 MJ/Kg. The figures will vary a bit from one engine to another, and from one grade of fuel to another.

(from Wikipedia)

calorific value means the total amount of heat energy evolved when 1gm of the fuel is completely burnt.

from the combustion equation find out enthalpy of combustion.then divide the molecular weight to that quantity.

Diesel engines come in all sizes. Some smaller and some quite larger than gasoline engines. A diesel engine makes no more H.P. than a gasoline engine but makes lots more torque and it's H.P. at low RPMs. Diesels typically have a compression ratio of around from 16 to 1 to as high as 23 to 1. Most gasoline engine will have around a 9 to 1 ratio. The higher compression ratio of a diesel allows it to make much more torque at lower RPMs. Torque is pulling power which is what a truck needs.

Of an individual diesel engine and an individual steam engine of the same energy output the diesel engine would be less polluting. It is far more efficient.

However, there are far more diesel engines than steam engines in the world today so overall diesel engines pollute more than steam engines.

Diesel engines run much higher compression than petrol engines. The higher compression makes the air in the cylinder so hot that the fuel self ignites. A petrol engine doesn't get warm enough for self ignition, so you have to add a spark from the spark plug to ignite the fuel.

No.

Diesel and petrol, while both petrochemicals, act quite differently. Petrol is ignited by a spark, and at a relatively low pressure. Diesel 'self ignites' when placed under sufficient pressure, therefore diesel engines do not use spark plugs, and require higher operating pressures to work.

To allow for the different pressures, there are large differences between the designs of petrol and diesel engines, carburettors/fuel injectors and valve systems.

The only way to convert a petrol car to a diesel (or vice versa) is a complete engine swap.

The freezing point of pure gasoline depends on the difference in hydrocarbons. There are heavy and light hydrocarbons like paraffins and aromatics, respectively. Pure unleaded freezes around -150F and varies with addition of solutes such as water.

I believe the pump is in the fuel tank on your car and just pull the tank and replace the pump. The less gas you have in it the easier it is to handle. On some cars you have to drop the exhaust system some.

I assume by gasoline that's the same as unleaded/petrol.... Well basically you will not do any serious damage to the engine itself, the car will stop working, quite possibly have some black smoke coming out the exhaust as the diesel works it way through, you will not be able to use the car until the entire fuel system has been drained out, so its a costly and frustrating mistake to make.

Hexadecimal is commonly used in comoputing to represent a memory byte.

A compression ignition engine works with Pistons and Valve openings.

There is an intake valve, with lets the fuel and air into the cylinder, and the exhaust valve which allows for the escape of the combustion.

The engine starter, supposedly started by a battery, gives the piston an Initial movement away from the valves, which bring the fuel and air into the cylinder, then pushes the piston back up, with this mixture of fuel, which is at a certain mixture which is then ignited by a spark plug. The explosion throws the piston back down which releases the exhaust valve allowing for the exhaust to exit. Once the exhaust leaves the piston moves back up , probably by the flywheel... and is brought down again which allows another mixture of fuel. This allows the engine to begin on its own timing without the need of a starter.

The specific heat capacity of wood varies as a function of the type of wood and also the moisture content. A figure of 0.4 to 0.5 will get you in the ball park, but numbers can stray well above and below that range. Dry balsa and a chunk of fir that was just pulled up from the bottom of a lake where it was snoozing for a hundred years will lie outside the given values. By giving it a bit of thought, you can see why. This may not help you solve a specific problem, but it will allow you to assess the variables and perhaps come up with a "best guess" for your specific application.

When we are making a thermodynamic analysis of a system where diesel fuel is combusted we use the heating value of the fuel. You must determine whether you should use the higher heating value (HHV), or lower heating value (LHV), based on the application. Hope this helps.

Some examples of biofuels would be, ethanol, straw, etc. Anything that is organic and can be grown by humans in mass. Lamp oil, flaxseed oil, peanut oil (substitutes for diesel), turpentine, plant-based ethanol, and biomass methane gas are all examples of biofuels.
