AIR-STANDARD ANALYSIS: INTERNAL COMBUSTION ENGINES Air-standard analysis treats the fluid flow through the entire engine as air and approxi¬mates air as an ideal gas. In a real engine inlet flow may be all air‚ or it may be mixed‚ up with 7% fuel‚ either gaseous or as liquid droplets‚ or both. In air-standard analysis‚ even if all fluid in an engine cycle were air‚ some error would be introduced by assuming it to be an ideal gas with constant specific heats. At the low pressures of inlet and

The steam engine is one of the very first inventions during the Industrial Revolution and one of the most important invention ever created. A steam engine was a machine that used heat‚ water‚ and coal to power it. The steam engine was used in many different things‚ from water pumps in mines to trains. Steam engines helped this world get to where we are today. The steam engine had a rough start‚ but when people realized it could be used for more then just pumping water‚ it began to be used in bigger

Gas engines versus diesel engines have been a long time opponent. Each has its own pros and cons but its really what your needs demand. Power and torque is a big player in this. If you want higher horsepower and fast acceleration‚ a gas engine is for you. If you need to tow objects and need a lot of low-end power a diesel engine would suit you. Fuel economy can play a bigger part in your decision. Diesel engines usually have a better fuel economy rating because of the way they don’t waste fuel during
