a い يكا 4 +91- pu Answer the following statements by true or false, giving the reason for your answer: 1. Injection pressure in CI engines should be sufficiently high. 2. The purpose of the condenser in battery ignition system is to prevent spark in the ignition coil assembly. 3. An idling engine requires lean mixture of fuel and air. 4. Factors which decide optimum engine firing order are engine vibration, engine cooling and back pressure. 5. It is the duty of the header to control over speeding during CI engine operation when drastic reduction in load occurs. ---20125 750 x2.01 SP
