Superchargers are
Used to force more air-fuel mixture into the cylinder of a diesel engine
Used to force more air only to the cylinder of a gasoline engine
Usually of the rotary screw or the centrifugal type
used to increase power output
never used on gasoline engines
The pressure of the air at the end of the diesel compression stroke may be as high as:
1000 kPa
2000 kPa
500 kPa
4000 kPa
5000 kPa
Scavenging is:
The supplying of air for combustion
The removal of exhaust gases from the cylinder
Used in all diesel engines
Usually used in four-stroke cycle engines
Re-circulation of exhaust gases to reduce emmisions
In a closed-cooling system for an internal combustion engine the:
Pump takes suction directly from the engine
Pump is on the low temperature side of the engine
Expansion tank is on the water supply side of the engine
Cooling water is circulated intermittently
Radiator is between the pump discharge and the engine
Solid fuel injection systems on IC engines may use which of the following designs or variations: 1. Individual pump 2. Air injection 3. Distributor 4. Common rail
1,2,3
2,3,4
1,2,4
1,3,4
1,2,3,4
In the distributor system for the injection of fuel into a diesel cylinder:
Two pumps are used
One common pump is used
One pump is used for each cylinder
Only a metering pump is used
Pumps are not required
The wet type of cylinder liner is:
Water cooled
Oil cooled
Made of white metal
Submerged partly in oil
Filled with water
The camshaft in an internal combustion engine is driven by a/an:
Rocker arm
Electric motor
Connecting rod
Chain or belt
Hydraulic pump
A magneto ignition system:
Does not require a coil
Produces AC power
Produces a hotter spark at high speeds
Does not require points
Does not require a condenser
The pressure at the discharge of a supercharger may be as high as:
100 kPa
120 kPa
10 kPa
30 kPa
140 kPa
