70% to passWith respect to diesel fuel, the ease with which a cold engine will start is dependent upon the_______________.
Aignition quality of the fuel
Bhigh heating value of the fuel
Camount of carbon residue after combustion
Dinternal flow resistance in the injectors
AI Explanation
The correct answer is A) ignition quality of the fuel. The ease with which a cold diesel engine will start is primarily dependent on the ignition quality of the fuel, which is measured by the fuel's cetane number. Fuels with a higher cetane number have better ignition characteristics and will ignite more readily in the cold engine, making it easier to start. The other factors, such as heating value, carbon residue, and injector flow resistance, are not directly related to the cold starting performance of the diesel engine.
