Which has a highest starting ignition between petrol n diesel?
Diesel has highest ignition temperature.. So only diesel cant be used in petrol engine
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 can't petrol be compressed and ignited as in the case of diesel engines?
petrol self ignition temperature is high and requires a spark plug instead to ignite.where as diesel ignites automatically under pressure because of low self ignition temperature without any spark plug....hence petrol cannot be used inplace of dieselWarning: The above answer is absolutely incorrect. Petrol's flash point is significantly below, not above, diesel. The heat needed for ignition in a diesel engine comes from a compression ratio of over 20:1. Petrol engines have compression ratios of less than 10:1. Even at this lower compression ratio, petrol will still sometimes flash over or "detonate," causing the engine to "knock." This kind of nonsense is why I stopped posting here.
What is the Ignition temperature of petrol?
246 degree Celsius............
What is ignition temperature of petrol?
246 degree Celsius............
Why petrol does not catch fire on its own temperature?
Petrol has a high ignition temperature, which means it requires a certain amount of heat to ignite. The autoignition temperature of petrol is around 246 degrees Celsius, which is higher than typical ambient temperatures. This is why petrol does not catch fire spontaneously at normal temperatures.
What are the defferences between dessel and petrol engine?
Petrol & Gas engines are spark ignited engines where as diesel engines are compression ignited engines. Petrol engines works with explosion of fuel air mixture due to spark from spark plug inside the cylinder. Diesel engines works with combustion of fuel air mixture due to compression, compressed mixture attains a very high temperature which exceeds the flash point of diesel and starts burning inside the cylinder and the hot gases after burning of fuel misture exerts force on piston which makes the diesel engines work. Diesel engines are highly efficient than petrol engines.
What is spark ignition or Diesel?
spark ignition engine is also known as petrol engine. but in diesel engines the fuel is burnt due to the high compression of air.so there is no need of spark plug
Does petrol boil at a higher temperature than diesel?
No. I'm not sure of the exact numbers. Petrol will boil off of your hand, while Diesel will not. Try it if you get the chance.
How many types of spark ignition engine?
There are basically two types of spark ignition engine. They are the diesel spark engines and the petrol spark engines.
Why is petrol engine RPM is greater than diesel engine?
for same power diesel engine produces more torque @ less rpm whereas petrol engine produces less torque @more rpm this difference is due to different combustion processes of diesel and petrol
What is cetane number for petrol?
There is no cetane number for petrol. Cetane is a measurement of Diesel fuel and Octane is a measure of Petrol. Each is a measure of the combustion ability. Cetane is a measure of the amount of time from injection of the fuel into the combustion chamber and the actual ignition of the fuel. Diesel's ignite the fuel through compression and not spark as in a petrol engine.
