Difference between ignition temperature and self ignition temperature?
The air temperature in a diesel engine cylinder is 1022 F. This will ignite the fuel. the high compression, 22 to1, will light the fuel. A spark engine with a carburetor may "diesel" when the key is turned off because of glowing carbon deposits in the cylinder, self ignition.
Fire point of diesel?
As low as 126 degrees Fahrenheit, diesel fuel could potentially catch on fire. This is known as the temperature of ignition.
What is the difference between ignition temperature and spontaneous ignition temperature in a fuel cell?
The minimum temperature the fuel ignites self sustained combustion is known as spontaneous ignition temperature. The temperature at which the substance is preheated and burns smoothly is known as ignition temperature.
Which has a highest starting ignition between petrol n diesel?
Diesel has highest ignition temperature.. So only diesel cant be used in petrol engine
How many BTU per gallon of diesel fuel?
One gallon of diesel fuel is equal to 139,200 BTU. The man who invented the compression-ignition engine was Rudolf Diesel. This is where diesel fuel gets its name.
What is the difference between a diesel engine and a petrol engine ignition of mixture?
petrol engine - Fuel and air mixtures together and compressed in engine. These mixtures ignited by Spark plug Diesel Engine - Air only compressed at high pressure and Temperature. Fuel injected at high temp so that the ignition takes place
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 does a diesel engine use a different type of fuel?
Diesel engines do not require "ignition" to burn diesel fuel--it is powered by the "heat of compression" therefore diesel fuel has a much higher "flash point" than gasoline. If you were to put gasoline in a diesel engine you would probably blow the heads off the engine. Due to lower "flash point" (temperature when fuel ignites). If you were to put diesel fuel in a gasoline powered engine, it would not ignite and engine will not start. Due to higher "flash point).
Is a gasoline-diesel fuel a good mixture to get more power from a diesel engine?
not at all. that will cause engine damage. gasoline burns at a much lower temperature than diesel fuel so you will get pre ignition. diesel fuel has more useable power in than gasoline. gasoline is rated in octane and diesel fuel is rated in cetane. with diesel fuel the higher the cetane the faster the fuel will burn for a more complete combustion. so if you want more power from a diesel a place to start is a higher cetane diesel fuel. but things like bigger trubos, vgt turbos, injectors, intercoolers have a much bigger effect on power than fuel
How is fuel injection different from spark ignition?
Diesel fuel injection injects fuel into air that is hot enough to ignite the fuel. Spark ignition takes a fuel air mixture mixed and then drawn into the cylinder before ignition, then ignites with an electric spark.
Does diesel compress?
Disel fuel, like all oils, isn't compressible. Diesel engines relies on compression for ignition.
Spark plugs cause the ignition in Diesel engines?
No, spark plugs do not cause ignition in diesels. The fuel compression causes ignition
