Welcome back abena — missed you this week. Here are the answers to question 1: a) The method of transferring heat from the engine to the radiator is primarily through convection via the circulating coolant. b) Step 1: Convert the stroke length from millimeters to meters. Distance = 70 mm = 0.070 m Step 2: Calculate the work done using the formula Work = Force × Distance. Work = 100 N × 0.070 m Work = 7 J The work done on the piston during the stroke is 7 J. c) Four possible causes for the oil pressure gauge reading zero when the engine is running are: • Low engine oil level • Faulty oil pump • Clogged oil filter • Faulty oil pressure sensor or gauge d) The function of the fuel pump is to draw fuel from the fuel tank and deliver it to the engine's fuel system (e.g., carburetor or fuel injectors) at the correct pressure and volume. e) Suitable air/fuel ratios for an engine under the following operating conditions: i. starting from cold: 9:1 to 10:1 (rich) ii. idling: 12:1 to 13:1 (slightly rich) iii. acceleration: 12:1 to 13:1 (rich) iv. economy: 15:1 to 16:1 (lean) Send me the next one 📸
