- Q1Which part of an automotive engine controls the timing of the intake and exhaust valves?Spark plugCamshaftPistonCrankshaft30s
- Q2What is the purpose of the lobes on an automotive engine camshaft?To control the engine temperatureTo adjust the tire pressureTo open and close the intake and exhaust valvesTo generate electricity for the car30s
- Q3What is the function of a camshaft in an automotive engine?To monitor tire tread wearTo control the timing of the opening and closing of the intake and exhaust valvesTo regulate the fuel injection pressureTo adjust the steering wheel alignment30s
- Q4Which type of camshaft allows for variable valve timing in an automotive engine?Rotary camshaftPushrod camshaftFlathead camshaftOverhead camshaft (OHC)30s
- Q5What is the purpose of a camshaft position sensor in an automotive engine?To monitor the position and speed of the camshaftTo control the windshield wipersTo regulate the fuel flow to the engineTo adjust the air conditioning temperature30s
- Q6What is the relationship between the camshaft and the crankshaft in an automotive engine?The camshaft controls the timing of the valves while the crankshaft converts linear motion into rotational motionThe camshaft monitors tire tread wear while the crankshaft regulates the engine temperatureThe camshaft generates electricity for the car while the crankshaft controls the fuel injectionThe camshaft regulates the tire pressure while the crankshaft adjusts the steering wheel alignment30s
- Q7What is the purpose of a performance camshaft in an automotive engine?To increase power output and improve engine performance at high speedsTo enhance interior comfort and reduce noise levelsTo generate more engine coolant for temperature regulationTo decrease fuel consumption and improve fuel efficiency30s
- Q8What is a camshaft made of in most automotive engines?Steel or cast ironCopper or bronzePlastic or rubberAluminum or carbon fiber30s
- Q9How does a performance camshaft differ from a stock camshaft in an automotive engine?A performance camshaft has more aggressive profiles for increased lift and durationA performance camshaft has fewer lobes for simpler valve controlA performance camshaft is made of plastic for weight reductionA performance camshaft is designed for slower engine operation30s
- Q10What is the purpose of a camshaft in an overhead cam (OHC) engine design?To adjust the suspension system for a smoother rideTo control the air conditioning system inside the vehicleTo regulate the cooling system of the engine blockTo directly operate the intake and exhaust valves above the cylinder head30s
