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.
Diesel has highest ignition temperature.. So only diesel cant be used in petrol engine
the fuel produces has higher ignition temperature and produces more heat
It has a flash point of about -50° F (-65° C)(lowest temp ignitable). The ignition temperature is about 495° or autoignition which it can go off without external spark source.
The burning temperature of diesel is higher than that of petrol. Diesel ignites at a higher temperature compared to petrol.
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.
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
As well as petrol you need oxygen and an ignition source
The flash point of petrol represents the temperature at which it can ignite when exposed to an open flame. However, for petrol to combust, it must also be in the presence of oxygen and have an ignition source. In summer, the atmosphere temperature being higher than the flash point of petrol alone is not sufficient to cause it to catch fire without these additional factors.
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.
