The ____________ is the infrastructure around which the rest of the rig is assembled.
what is the frame.
these two fuels provide the power for a tractor-trailer.
What are gasoline and diesel?
Prior to having computers trucks were considered _________________.
What is hydromechanical.
A hydromechanical engine—or more accurately, a hydromechanical fuel control unit (HMU)—is a mechanical and hydraulic system used in gas turbine jet engines to safely and precisely regulate fuel flow. It interprets pilot throttle commands and environmental conditions to meter the exact amount of fuel needed for stable combustion, acceleration, and thrust
This typical path for fuel starts here, cleans here and ends here.
What is tank, filter injector?

What is the air intake?
These attach to the frame and hole the engine is place.
What are engine mounts.
Engines that gas and diesel are what types of engines?
What is internal combustion?
This EPA regulation / requirement triggered the introduction of computerized engine controllers and have been the driving force behind their evolution.
What is emissions?
Heating fuel is done in one of these three ways.
What is in the tank, inline, and/or in the filter.
This part of the air intake system removes dirt, dust, and water from the fresh air.
What is the air filter?
The _____________ system supports, distributes, and carries the weight of the truck.
What is suspension?
A single sweep of the cylinder by the piston in an upward or downward motion is known as a ___________.
What is a stroke?
ECU= _____________
What is Electronic engine control?
This container is deigned to hold the trucks fuel. Most larger trucks have two of these.
What is a fuel tank?
From the air filter, clean air flows to the ______________.
What is the intake manifold?
Two types of suspension system include
What are spring leaf and air bag?
A large block of steel with holes, or cylinders, drilled through it.
What is the engine block?
ECM= ________________
What is Engine/electronic Control Module
This cleaning system has a coarse filter, a finer filter and a filter/water separator which protects the injector jets and engines from water, rust, and other contaminants.
What are the fuel filters?
After combustion occurs, this system expels used gases
What is the exhaust system?
What are live axles?
Extreme compression of this fuel and air mixture in the cylinder by the piston squeezes it so much that this fuel ignites.
What is diesel?
The management system for current vehicle systems tends to be classified by the degree of control they have over the fueling pulse. They are ___________ and ____________.
What is full authority and partial authority systems?
This onboard state of the art component figures the right amount of fuel and the injects it into the cylinder at exactly the right time and at the right pressure.
What is the computer?
A pyrometer measures ___________________.
What is exhaust gases tempature?
