Four stroke engineVersión en línea Identifica los cuatro tiempos de funcionamiento de un motor de combustión interna. por Yanet Rivero 1 Select the basic components of a four stroke engine a A pistol, a connecting rod and a crankshaft b A piston, a conserving rod and a cranshaft c A piston, a connecting rod and a crankshaft 2 Select the transformation of the motion that occurs inside the cylinder a The horizontal motion of the piston generates an oscillating motion of the crankshaft b The lateral motion of the piston generates a circular motion of the crankshaft c The vertical motion of the piston generates a lateral motion of the crankshaft 3 The fuel delivery system consists of a An air intake manifold b Intake and exhaust valves c A fuel injector d A spark plug e All the answers are correct 4 A four stroke engine is called this way because... a two up motions are needed to complete the cycle b four up and down motions are needed to complete the cycle c four down motions are needed to complete the cycle d A spark plug e All the answers are correct 5 On the first stroke or intake stroke... a Air from the atmosphere enters the cylinder b A metered amount of gas from the electronic fuel injector enters the cylinder c Air from the atmosphere and a metered amount of gas from the electronic fuel injector enter the cylinder d A spark plug e All the answers are correct 6 On the second stroke or compression stroke... a the piston moves upward to compress the air and the fuel, to make a highly combustible mixture b the piston moves downward to release the air and fuel c the piston stops to maintain air and fuel inside the cylinder d A spark plug e All the answers are correct 7 On the third stroke or combustion stroke... a the spark plug fires sending the piston upwards b the piston travels down and upwards c the spark plug fires sending the piston downwards d A spark plug e All the answers are correct 8 On the fourth stroke or exhaust stroke... a the piston travels upwards and the exhaust valve opens to release air fuel mixture b the piston travels downwards and the exhaust valves closes c the piston travels down and upwards to release air fuel mixture d A spark plug e All the answers are correct 9 To create one revolution of the crankshaft (rpm) a four strokes of the piston are needed b two strokes of the piston are needed c two up-and-down motion of the piston are needed d A spark plug e All the answers are correct 10 RPM means a Revolutions per minute b Resolution per minute c Revolution per movement d A spark plug e All the answers are correct 11 The crankshaft can rotate at 5000 rpm, that means... a the crankshaft rotates 83 times on a second b the piston moves up-and-down 83 times on a second c the crankshaft rotates 83 times and the piston 166 times on the same second d A spark plug e All the answers are correct
