Calculate the thermal efficiency, indicated and brake power output and torque of a single cylinder, four stroke 1.0 liter spark ignition engine assuming that it runs according to the ideal Otto Cycle (at full load, WOT at 3400 rpm) Calculate conditions (T and p) at state (1), (2), (3) and (4) of the Otto Cycle. Engine data and operating conditions are given as; Engine bore to stroke ratio is 1.(0 Compression ratio is 10:1 Mechanical efficiency is 85% Combustion efficiency is 98% Fuel is iso-octane with a heating value of 44300 kJ/kg Air/Fuel ratio is 15:1 At the beginning of the compression stroke conditions in the cylinder are 100 kPa and 50 °C Discuss vour results and indicate any deviations from the real engine opearting conditions.

the warning light flashes for a second or two when the engine starts. if it stays on, there's must be something wrong with the coolant. you should never dare to continue driving when the light is on. pull over as soon as possible and shut the engine off.

hope this is what you're talking about

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of
