- Which of the following are not typically found in the block of a modern engine? a. Pistons b. Crankshaft c. Valves d. Oil pumparrow_forwardWhich of the following statements about engines is not true? The engine provides the rotating power to drive the wheels through the transmission and driving axle. Only gasoline engines are classified as internal combustion. The combustion chamber is the space between the top of the piston and the cylinder head. For the combustion in the cylinder to take place completely and efficiently, air and fuel must be combined in the right proportions.arrow_forwardWhich of the following statements is incorrect? Cylinder head bolts must be tightened to the proper amount of torque. Most cylinder head bolts are tightened in a sequence that starts on one end. On some engines, the head bolts are retorqued after the engine has been run and is hot. Many engines use head bolts of different lengths.arrow_forward
- Technician A says that crankshaft counterweights offset the weight of the connecting rods and pistons. Technician B says that crankshaft counterweights are used to dampen crankshaft torsional vibrations. Who is correct? Technician A Technician B Both A and B d. Neither A nor Barrow_forwardWhile preparing to remove an engine: Technician A turns the crankshaft pulley to set the engine at number 1 cylinder TDC. Technician B removes the drive belt and crankshaft pulley. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forwardWhich of the following statements about the purpose of a cylinder head gasket is not true? It seals intake stroke vacuum, combustion pressure, and the heat of combustion. It prevents coolant leakage and resists rust, corrosion and, in many cases, meters coolant flow. It allows for lateral and vertical head movement as the engine heats and cools. It meters lubricating oil onto the engines cylinder walls.arrow_forward
- True or False? The first step in removing an engine is usually the removal of the intake and exhaust manifolds.arrow_forwardA vehicle is producing a sharp, metallic rapping sound originating in the upper portion of the engine. It is most noticeable during idle. Technician A diagnoses the problem as piston pin knock Technician B says that the problem is most likely a loose crankshaft thrust bearing. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forward1. Which engines can have their cylinders located below the crankshaft? Radial Engines In-Line Engines V-type Engines Opposed-Type Engines True or False: John Barber created the first practical heat engine. V-type engines have the least vibration in all types of reciprocating engine. Single-type radial engines can have 6 cylinders.arrow_forward
