Diesel heat of combustion : 45 MJ/kg , 10.7 Mcal/kg 19,300 BTU/lb
Diesel fuel contains compounds of sulfur that are oxidized during combustion to produce sulfur trioxide, which dissolves in water to form sulfuric acid.
the organic (or certain inorganic) compounds oxygen (generally excess) heat
how does the heat of combustion of propane compare to the heat of combustion of paraffin wax
Depending on the situation I would say the most likely cause is oversaturation of the fuel or insufficient oxygen.
oxygen. the definition of combustion is: a substance reacting with oxygen to create heat and light.
The diesel engine doesn't have any spark plugs, and uses heat generated during compression to ignite the fuel. The diesel however, is an internal combustion engine.
Petrol and diesel engines are internal combustion engines. The internal combustion that turns the engine and powers the wheels is created by the combustion of fuel. No fuel, no combustion, and nothing to drive the wheels.
The calorific value of fuel is the quantity of heat produced by its combustion at a constant pressure and under normal conditions. For diesel, the calorific value is 44,800.
Combustion requires Heat, Fuel and Oxygen
Any combustion needs Fuel, Oxygen and heat. In a petrol engine, the fuel and air are mixed in either a carburettor, or a fuel injector system. The heat is supplied by the spark plug and maintained once the mixture is burning rapidly. The massive expansion of the burning gas, is used to push the piston. In a CI (compression ignition diesel) engine, The air is drawn in, diesel fuel is sprayed into it and the piston compresses it. This compression alone, causes heat, which is enough to cause combustion. The same expansion of the burning gas, is used to do work on the piston.
Diesel is a type of internal combustion engine wherein the fuel is ignited solely by heat produced by rapid compression of the air in the cylinder. Not by an electrical spark as in a gasoline engine. As the cyl air is compressed the air becomes heated. Fuel is injected into the hot cylinder and is ignited by the heat alone
Steam engine: external combustion (the fuel is burnt in the boiler and the steam led through pipes etc to the power cylinder(s). Diesel (and petrol and gas): internal combustion - the fuel is burnt in the cylinder. Otherwise they are all Heat Engines.
combustion energy
Spelled as diesel, this type of internal combustion engine uses the heat of compression to ignite the air/fuel mix, and has no spark plugs.
Through combustion they produce heat.
