Internal Combustion Engines Which of the following statement is correct regarding petrol engines? All of these The fuel is first evaporated after passing through a carburettor and is mixed with air before ignition The fuel supplied to the engine cylinder is mixed with necessary amount of air and the mixture in ignited with the help of a spark plug A fine fuel spray mixed with air is ignited by the heat of compression which is at a high pressure All of these The fuel is first evaporated after passing through a carburettor and is mixed with air before ignition The fuel supplied to the engine cylinder is mixed with necessary amount of air and the mixture in ignited with the help of a spark plug A fine fuel spray mixed with air is ignited by the heat of compression which is at a high pressure ANSWER DOWNLOAD EXAMIANS APP
Internal Combustion Engines The frictional power (F.P.) is given by F.P. = P. P. - I.P. F.P. = I.P./ F.P. = I.P. - F.P. = P./I.P. P. F.P. = P. P. - I.P. F.P. = I.P./ F.P. = I.P. - F.P. = P./I.P. P. ANSWER DOWNLOAD EXAMIANS APP
