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.
Full form of SI engine?
SI stands for Spark Ignition. eg. Petrol Engine.
What is the difference between a reciprocating internal combustion engine and compression ignition combustion engine?
Compression ignition is deisel. Otherwise, spark ignition is gasoline.
What is the ignition timing for a 302 Windsor?
This is the amount of time that it takes the ignition to start. This information would be present in the users manual.
What are the different phases of combustion in a petrol engine?
1) Inlet, 2) Compression, 3) Ignition, 4) Exhaust. Otherwise known as; Suck, squeeze, bang, blow. 1) Fuel / air mixture is injected/drawn into chamber. 2) Mixture is compressed by piston. 3) Spark, and mixture burns, pushing piston down 4) Piston returning to top of cycle pushes out burnt exhaust gases.
What is firing point of petrol?
fire point of petrol
Does an mpfi engine replace spark plug?
No. Spark plugs remain in Petrol engines. MPFI stands for Multi Point Fuel Injection, thus replacing the carburetor with injectors. Petrol engines need a source for ignition unlike Diesel engines, where the ignition happens due to compression.
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 Ignition temperature of petrol?
246 degree Celsius............
What is ignition temperature of petrol?
246 degree Celsius............
Which other element must be present for petrol to burn?
As well as petrol you need oxygen and an ignition source
Can a lit ciggarette light petrol?
I swear I saw a Myth Busters (Discovery Channel) on this very question...Extremely difficult at best, and not very likely.Note: it is not the liquid petrol (gasoline for us Yanks) that fires up - it's the vapors that are the point of ignition.
Why petrol does not catch fire in summer even when its flash point is 44 celsius and temperature of atmosphere is 50 Celsius?
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.
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 will be the state of melting point and boiling point of petrol?
Petrol is a complex mixture of hydrocarbons and its composition can vary. Typically, petrol has a low melting point and boiling point range due to its composition of lighter hydrocarbons. The boiling point of petrol is generally around 30-200°C, while the melting point is typically below -50°C.
How are internal combustion engines?
you cut off the ignition spark in a petrol engine
Who has the lowest boiling point fraction petrol or diesel?
Petrol has a lower boiling point than diesel. This is because petrol is a lighter fraction of crude oil, consisting of shorter hydrocarbon chains, which results in a lower boiling point compared to diesel.
