Fuel
Air
Diesel engines are said to have _______ combustion while gasoline engines have ______ combustion
Constant pressure
Constant volume
The pump of the torque converter is capable of multiplying engine torque by approximately ___ to ___
2.2 to 1
Clutch, cannot slip clutch for more than ____ secs
1 1/2 seconds
Lockup clutch, lockup occurs in all forward gears, but not reverse in _____
Automatic transmissions
Differential, if one wheel is stopped the other wheel will spin _____ as fast
Twice
Air is compressed to approximately ___ psi in a Diesel engine
500 psi
The purpose of the power train is to transmit the power of the engine to the ___\
Drive wheels
Speed and power of s diesel are controlled by _________\
Amount of fuel injected into the cylinder
Driveline must be _______ if the engine cannot be started by towing or pushing beyond a few blocks
Disconnected
Heavy apparatus have ___ axles
Full floating
A ____ is an axle that supports part of the weight of the vehicle and also dives the wheels that are connected to it
Live axle
Temperature of compression stroke in Diesel engines =
1000°, 500 psi
Diesel= constant _____
Gasoline = constant ____
Pressure
Volume
On heavy apparatus, full floating axles can be removed w/o removing rear wheels
True
Clutch driving manners, flywheel, pressure plate, intermediate plate
Yes
Driven members, clutch plates, input shaft and transmission
Yes
Prop shaft of the same diameter, Hollow= weaker Solid= stronger Same weight= stronger Solid= weaker
Hollow
Solid
Same weight
Solid
The main difference between gasoline and diesel engines is the method of introducing fuel into the cylinder and igniting the fuel air mixture. True or false
True
In diesel engine there is continuous combustion during the entire length of the______.
Power stroke
Gasoline engine is often referred to as having constant volume combustion while diesel is said to have constant _____ combustion
Pressure
Diesel= constant _____
Gasoline= constant _____
Pressure
Volume
The clutch brake should never be used with the apparatus in motion. True or false
True
A U-joint is a flexible coupling between two chefs the permits one shaft to drive another. True or false
True
The mail spleen is an integral part of the propeller shaft
True
PS I in the compression stroke of a diesel engine is as high as 500 psi as compared to 70–1 25 psi in a gasoline engine
True
Diesel engine; heat of compression is used to ignite the fuel-air mixture
True
For each pound of pressure exerted there will be an increase of about 2°F, thus the temperature of about 1000°F is reached during compression
True
The speed and power output of diesel engines are controlled by the quantity of fuel injected into the cylinder
True
On a two-stroke engine the intake and exhaust ports are found on the sides of the cylinder
True
Torque converter (2) functions: Act as a fluid coupling and multiplies torque
True
A live axle supports part of the weight of the vehicle and drives the wheels connected to it
True
3 basic parts to a torque converter=
Pump, turbine and stator
The transition provides the means to reverse the direction of power flow
True
