250+ TOP MCQs on I.C Engine – Working Principles of 4-stroke Engine and Answers.
250+ TOP MCQs on Engine Performance Parameters and Answers.In an I.C.engine, usually the inlet valves open. In simpler terms, it is the way an engine ‘breathes’. Simply defined, it is the timing, or regulation of the opening and closing of the valves. 250+ TOP MCQs on Engine Power and Answers VALVE TIMING (VT) is one of the most important aspects of consideration in the design of an automobile engine.250+ TOP MCQs on Performance Parameters and Characteristics and Answers.> Related Posts of Above Questions ::: -><<. _ is used to check the state of charge of a battery.Ĭlarification: Battery charger is used to check the state of charge of a battery while hygrometer is used to check the air humidity and hydrometer is used to check the specific gravity.
