If it was, the engine wouldn't work - you would be putting more energy in than you got out.

How much compression should a diesel have?
A diesel engine requires at least a 20:1 compression ratio, or about double a gasoline engine. The PSI this translates to depends on the size of the cylinder. You will need to consult the manufacturer's service manual.
What type of internal combustion engine has no spark plugs?
The diesel engine, which ignites the fuel vapors by compression within a preheated cylinder.
Why do diesel engine has a greater noise than gasoline engine?
The fuel is ignited by compression and not by a spark plug. The compression of the cylinders is much higher than in a gas engine. The fuel must be compressed to the point at which it will ignite. This cause the noise you hear from a diesel engine.
How do we use the diesel engine now?
The diesel engine is on compression.
What lights the fuel in a diesel engine?
Diesel fuel is ignited by a combination of heat and compression. The heat is caused by the very high compression in the cylinder. The fuel also has to be very finely atomised to be able to burn.
What is the compression ratio of and engine?
Compression ratio is the difference in the volume of a engine cylinder between when the cylinder is at it's largest volume, compared against when the cylinder is at it's smallest volume. Gasoline engines use 8:1 to 12:1 compression ratio. Diesel fuel engines use 14:1 to 25:1.
Why diesel engine has volumetric efficiency greater than gasoline engine?
In diesel engine the air is only compressed in compression stroke and then diesel is entered .......so only small amount of fuel is consumed then petrol engine which take lot amount of fuel.......
What are typical compression test reading for a diesel engine in good condition?
typical compression test reading fora diesel engine
How is diesel fuel ignited in a warm diesel engine?
Compression.
Why during the ignition pressure remain constant in diesel engine?
The ignition temperature, (temperature at which diesel fuel ignites) is 490*F. This temperature corresponds to a set compression of the gasses in the cylinder of the engine. Some, but not all, diesel engines have glow plugs to initially warm the air when you first start the engine because the temperature of the air in the diesel engine is too cold to get the ignition temperature simply from compression. while the engine is running the compression heats the air to the ignition temperature. This compression (or pressure) is the same each time the cylinder fires. Using the universal gas law you can find that corresponding compression versus the ambient temperature and pressure. Typically this will occur at approximately 16 bars. Almost all diesel engines are designed to operate at a compression ratio of 15:1 - 20:1, less if supercharged or turbocharged.
Why in petrol engine spark plug is used but not in diesel engine?
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.
What is the typical compression in a diesel engine verses a petrol engine?
2.5 liter Petrol 8-1 diesel 25-1 compression
