Why do diesel engines ignite even though they have no spark plugs to ignite this mixture?
Compression and heat. The fuel/air mixture is compressed to such a high level as to get hot enough to cause the mixture to self ignite. Gas engines require a spark to ignite the fuel. Gasoline engines have a compression ratio of 8:1 to 12:1. Diesel engines have a compression ratio of 14:1 to 25:1.

What is the Difference between internal combustion engines and diesel engines?
There is no difference. Both are internal combustion engines. I think I know what you're asking though. A gasoline engine uses spark ignition and a diesel engine uses compression ignition. The gasoline engine needs an spark or other heat source to ignite the fuel air mixture in the cylinders. The diesel engine ignites the fuel air mixture by compressing it in the cylinders until it combust's from the heat produced when the cylinder's volume is decreased. In an external combustion engine, the working fluid is heated by burning fuel, then introduced into the expansion chamber to produce power e.g. a steam engine.
Why is petrol rate costlier than diesel?
Diesel and petrol engines work differently. Diesel engines use compression to ignite the air/fuel mixture, and have a much higher compression ratio than petrol engines, which use spark ignition. The conditions for ignition are not met when petrol is put into a diesel engine, and will stall.
What is the difference between diesel and gas fuel?
HI, The main difference is that a diesel engine uses compression to ignite its fuel, and a gas engine is the same as a petrol, it uses a spark to ignite its fuel. Diesel engines are more fuel efficient than petrol or gas. For instance if a diesel used 10 liters per 100kms a petrol engine of the same size in the same car would use roughly 12 liters per 100kms and a gas engine 15 liters per 100kms. Diesel engines are more ruggedly built to withstand the shocks and forces produced by compression ignition and therefore will generally last longer. Gas though, is the cheapest fuel on the Australian market so it is the cheapest to run in fuel cost. Personally I'm a diesel mechanic so i would say diesels are better, but if your after short term savings on the fuel bill I would go for a gas engine
What happens when you put in diesel fuel instead of regular unleaded gasoline?
The answer to the question of: "What happens when you put in diesel gas instead of regular unleaded?" is this...Diesel fuel (engines) rely on compression to ignite it. It isn't necessarily flammable.Gasoline relies on a spark from a spark plug. Diesel engines have a higher compression ratio than gasoline engines do, and thus provide more torque to the drivetrain (that's why 18 wheelers use diesel engines, instead of gasoline engines).So, if you put diesel fuel into a gasoline engine, there's not nearly enough compression to ignite the fuel. Probably the only thing that would happen is that your gasoline car or truck would run very rough for a time before all of the diesel fuel runs out.If you accidentally put diesel fuel into a gasoline fuel tank, the best thing to do is siphon it out.Finally, I can't imagine anyone accidentally putting diesel into a gas car since the diesel nozzle at the pump is a lot bigger than the gasoline nozzle...and it's that way for a reason. ;-)Though it does still happen every day when people fill up their cars without thinking exactly what they doing...For more information please see the answer to the Related Question shown below.I did this stupid thing today. It costs me 800 USD in the Toyota dealer. I did some internet search earlier. It would cost a lot fewer if you go other places. It would be no more than 500 USD. Be aware of this. Good luck!
Is diesel engine better?
It has advantages and disadvantages. Both are heat engines, and the diesel engine both puts out more BTUs and has a higher thermal efficiency rating - diesels are approaching the 50 percent margin, whereas gasoline/petrol engines are still in limbo in the low 20 percentile. Diesel engines are higher maintenance, though, and now, with Euro 5, EPA 2010, and other emissions regulations, they're required to run Diesel Exhaust Fluid in addition to the fuel they burn, which can add up in expense.
Can you use a carburetor with a diesel engine?
Apparently, you generally cannot do so because compression is needed for the detonation of the fuel mixture. Since diesel engines do not use ignition, more pressure in the cylinders is required. The fuel is vaporized directly into the compression chamber, which means that less volatile fuels can be used. Because only air is induced into the engine through the intake valve, the compression ratio can be much higher since there is no risk of pre-ignition as long as the injection process is accurately timed. There were tractors that used both gasoline and diesel fuel. They would start on gasoline, using a carburetor and an ignition system, then they would be switched over to diesel fuel. There are also diesel model engines which are carbureted, though the fuel is a little different.
What is a diesel automotive engine?
Diesel engines are used in many applications. They were invented by Rudolf Diesel in the 1890s. A diesel engine is an internal combustion engine that uses heat from the compression of the air to ignite the fuel when it is injected into the combustion chamber. In order for the temperature to rise high enough the compression ratio is ussually higher than 12:1. becasue of the high compression ratio their blocks and internal parts need to be heavier than comparable gasoline engines so they are more often used in heavier vehicals lke trucks trains or ships. Though they have been designed for small highly efficient compact cars like Volkswagans and Mazdas. They use a lower grade fuel than gasoline and can even use cooking oil or recycled motor oil.
What engine does a school bus have?
Really depends on the type. A Type A school bus might have a gas, diesel, or CNG engine.. those will use whatever is standard for the chassis manufacturer (e.g., Triton gas or Powerstroke diesel for Ford chassis, Vortec gas or Duramax diesel for General Motors chassis, Hemi gas or Cummins diesel for Dodge chassis). For Type B, C, and D buses, Thomas Built buses is owned by Daimler A.G. - the parent company of Freightliner, Western Star, and Mercedes Benz, and have been available with Cummins, Mercedes-Benz, or Caterpillar (until 2009) diesel engines or Cummins CNG engines. IC Bus is a subsidiary of Navistar International, and can have Navistar MaxxForce or Cummins diesel engines, or Cummins CNG engines. Blue Bird does not make their own engines, so they will use Cummins diesel or CNG engines. In the case of diesels, 6 - 7 liters is most likely what you'll find, though I have, in the past, seen school buses with 7.3 liter 3126 and C7 Caterpillars.
Is diesel renewable?
Only if it is bio-diesel, aka from plants. Most diesel is a product of crude oil though.
What is a good sentence for ignite?
Lightning or a brush fire can also ignite soft coal.Remove any one of the basic components, though, and the fire will either fail to ignite or will fizzle out by itself.Officials said a fire that had threatened to ignite the cars carrying the chemicals was still smoldering.The fire that he's been trying to ignite seems to be spreading.(Dictionary.com)
How reliable are Johnson GT 150 outboard engines?
They are OK engines. I would say that Yamaha engines are the best though.
Does an glider has engines?
no. a few variaties do though.
