What is the large casing that contains the cylinders and many of the internal components of the engine?
chassis |
|
manifold |
|
transmission |
|
engine block |
The engine (or cylinder) block is the large casing that contains the cylinders and many of the internal components of the engine.
For inline cylinder arrangements in an engine, how are the cylinders numbered?
alternating from the front of the engine to the back |
|
sequentially from the front of the engine to the back |
|
sequentially from the back of the engine to the front |
|
alternating from the back of the engine to the front |
Inline cylinder arrangements number cylinders sequentially (1, 2, 3, ...) front to rear.
The spark plug fires during which engine stoke?
compression |
|
exhaust |
|
power |
|
intake |
During the power stroke, just before the piston reaches top dead center, the spark plug fires and ignites the compressed air-fuel mixture. The resulting expansion due to combustion pushes the piston back down the cylinder toward bottom dead center.
Which of the following statements about v-type cyllinder arrangement is false?
common in motorcycles, cars, and trucks |
|
has an odd number of cylinders |
|
engine is shorter than an inline engine |
|
has two rows of cylinders |
A v-arrangement has two rows of cylinders in a V-shaped block with a crankshaft at the bottom of the V. Any even number of cylinders is possible in this configuration from the V-2 that's commonly used in motorcycles up to V-12 or bigger for large trucks. The V design produces a shorter engine than an in-line cylinder configuration and allows for better air-fuel distribution.
Cylinder air and fuel intake valves, exhaust valves, and mounts for spark plugs and fuel injectors are contained in the:
head gasket |
|
manifold |
|
piston ring |
|
cylinder head |
Cylinders act as a guide for the pistons that translate the heat energy of combustion into the mechanical energy necessary to move a vehicle. Piston rings seal the piston to the cylinder to contain combustion gases and also regulate the oil distribution between the piston and cylinder wall. A cylinder head closes in the top of the cylinder forming the combustion chamber which is sealed by a head gasket (head). The head provides space for air and fuel intake valves, exhaust valves, and mounts for spark plugs and fuel injectors.
