There is spark inginited( I.E. gas) and the other is C.I. compression ignition (Diesel), and that is the difference.
Diesel is ignited by the high cylinder pressure of a diesel engine, it is more eff. than a gas engine, because it burn more completely and can be run alot leaner than gas engines.
Gas engines currently available need a spark plug to ignite the fuel/air mixture noramlly running around 14.3 parts air to every 1 part fuel.
Under light throttle diesel can run closer to 40:1+, 4 times less fuel being burned.
Diesel run at a low rpm and with thier more robust construction can last at twice as long. Dodge/Cummins truck owners even have a million mile club( million miles on a stock engine)

What are the major advantages and disadvantages of using petrol in internal combustion engines?
Some of the major advantages of using petrol in an internal combustion engine include: ease of availability of petrol, non-corrosive nature of regular petrol, relative safety of liquefied petrol. Some of the disadvantages of petrol include: enviromental damage of unburned petrol and unrestrained Hydrocarbon emissions, steadily increasing price, petrol is relatively inefficient and production of CO2 even with perfect combustion.
What is the exhaust gas composition of internal combustion engines?
3 major gasses (as checked in an emission test) hydrocarbons, Co. & Nox (oxides of nitrogen) In exhaust gas of diesel engines (at correct fuel mixture) there was 13.8% CO2 (carbon dioxide) and 84.5% N2 (nitrogen).
The major changes of the second Industrial Revolution were in the development of .?

What caused a major increase in the demand for gasoline in the late 1800s and 1900s?
development of the internal combustion engine.
What are the major differences between V8 and V6 engines?
I beleive that is the number of cylenders which effects the power it can put out.

What are the relevance of science to the society?
Without science we would still be living in caves, without a fire. All the major innovations since prehistory are based on science. Fire, electricity, internal combustion engines (cars), cement, plastics, computers, medical treatments etc etc.

The development of the internal combustion engine
What is the main source of Energy for Transportation Systems?
today about dicious the petrol energy......petrol energy is the part of main source of energy for transportation systems.Petroleum: The Transport Fuel Almost all transportation modes depend on a form of the internal combustion engine, with the two most salient technologies being the diesel engine and the gas turbine, since they are the lynchpin of globalization. While ship and truck engines are adaptations of the diesel engine, jet engines are an adaptation of the gas turbine. Transportation is almost completely reliant (95%) upon petroleum products with the exception of railways using electrical power. While the use of petroleum for other economic sectors, such as industrial and electricity generation, has remained relatively stable, the growth in oil demand is mainly attributed to the growth in transportation demand. What varies is the type and the quality of petroleum derived fuel being used. While maritime transportation relies on low quality bunker fuel, air transportation requires a specialized fuel with additives. It is worth having a closer look at the chemical combustion principle of hydrocarbons. For the majority of internal combustion engines, gasoline (C8H18; four strokes Otto-cycle engines) serves as fuel, but other sources like methane (CH4; gas turbines), diesel (mostly trucks), bunker fuel (for ships) and kerosene (turbofans of jet planes) are used. In a complete and perfect combustion of gasoline the following chemical reaction is achieved:(2) C8H18 + (25) O2 = (16) CO2 + (18) H2O + energyGasoline produces around 46,000 Btu per kilogram combusted, which requires from 16 to 24 kg of air. The energy released by combustion causes a rise in temperature of the products of combustion. Several factors and conditions influence the level of combustion in an internal combustion engine to provide momentum and keep efficient operating conditions. The temperature attained depends on the rate of release and dissipation of the energy and the quantity of combustion products. Air is the most available source of oxygen, but because air also contains vast quantities of nitrogen, nitrogen becomes the major constituent of the products of combustion. The rate of combustion may be increased by finely dividing the fuel to increase its surface area and hence its rate of reaction, and by mixing it with the air to provide the necessary amount of oxygen to the fuel. If all internal combustion engines worked according to the above equation, emissions and thus local environmental impacts of transportation would be negligible (except for carbon dioxide emissions). The problem is that combustion in internal combustion engines is imperfect and incomplete for two reasons
