Fuel and fuel - Air - the start of the ignition of the oxygen mixture, how to modify or enhance the combustionBy an internal combustion engine of any form, using the nanosecond cycle high voltage pulse discharge and also relates the production of engine and energy engineering industry, the ...
Explain how the fuel-air mixture is ignited in a diesel engine. What are two auxiliary systems present in automotive gasoline engines that are not in an automotive diesel engine? What is the range of compression ratio of a diesel engine? What are...
In a gasoline engine, fuel is mixed with air, compressed by pistons and ignited by sparks from spark plugs. In a diesel engine, however, the air is compressed first, and then the fuel is injected. Because air heats up when it's compressed, the fuel ignites. The following graphic shows ...
Diesel fuel injection The fuel injection system in petrolengined cars is always indirect, petrol being injected into the inlet manifold or inlet port rather than directly into the combustion chambers . This ensures that the fuel is well mixed with the air before it enters the chamber. Many ...
What is a fuel cell?A fuel cell is a device that makes electricity from fuel and air. Instead of burning the fuel to make heat to drive a mechanical generator, fuel cells react the fuel and air electrochemically, without combustion. The electrochemical approach avoids pollutants that are ...
Boeing claim that the B787 Dreamliner uses 20-25% less fuel on a per passenger basis than the planes it replaces. This is one of the facts which Europe’s largest low-cost airline, Ryanair, uses to make claims about being Europe’s greenest airline, never mind that it has flown on ...
Several billion years after its life starts, a star will die. How the star dies, however, depends on what type of star it is. Stars Like the Sun When the core runs out of hydrogen fuel, it will contract under the weight of gravity. However, some hydrogen fusion will occur in the upp...
Combustion occurs when a substance -- the fuel -- combines rapidly with oxygen, producing heat and light. If you study a campfire or even a candle flame carefully, you will notice a small colorless gap between the wood or the wick and the flames. In this gap, gases are rising and ...
Gallons of fuel consumed per month 97.6 42.1 Gasoline costs per gallon $2.415 $2.539 Total monthly gas costs $235.70 $106.89 In practice, this means that even if the cost of fuel at the pump is higher in Connecticut, a Wyoming resident drives more than 2.3 times the distance and must retu...
It Can Hedge Fuel Costs:While fuel costs are a major variable expense, Delta uses fuel hedging strategies to mitigate the impact of fuel price volatility in the short run. By locking in fuel prices throughoptions contracts, Delta can better predict its fuel expenses and manage costs more effect...
