1

A constant velocity (CV) joint is closely related to which of the following?

63% Answer Correctly

master cylinder

ball joint

sprint joint

universal joint


Solution

Like CV joints, universal joints (U-joints) are located at each end of a drive shaft and allow the shaft to operate at a variable angle with the item it is driving. Universal joints perform the same basic function as CV joints but CV joints have a wider range of operation.


2

Which of the following statements about v-type cyllinder arrangement is false?

65% Answer Correctly

common in motorcycles, cars, and trucks

has two rows of cylinders

has an odd number of cylinders

engine is shorter than an inline engine


Solution

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.


3

What is the large casing that contains the cylinders and many of the internal components of the engine?

82% Answer Correctly

chassis

engine block

manifold

transmission


Solution

The engine (or cylinder) block is the large casing that contains the cylinders and many of the internal components of the engine.


4

Another name for the powertrain control module is the __________ control unit.

54% Answer Correctly

universal

transmission

electrical

engine


Solution

The main computer or powertrain control module (PCM) uses pre-programmed software to analyze the input received from sensors and produce output signals to adjust vehicle performance and operation. (Engine control unit (ECU) is another name for the PCM.)


5

What is the function of the head gasket?

75% Answer Correctly

to seal the engine block from the cylinders

to seal the exhaust system from the drive train

to connect the transmission to the drive train

to seal the brake assembly from external contaminants


Solution

A head gasket is a gasket that sits between the engine block and cylinder heads to seal the cylinders to ensure maximum compression and avoid leakage of coolant or engine oil into the cylinders.
