BASIC VEHICLE TECHNOLOGIES 2:
ENGINES Questions and Answers 100%
Solved
How does a variable-flow intake manifold help promote low-end torque at low to mid engine
speeds? Uses a longer airflow path, forcing a larger amount of air into the engine
What does a cylinder head do? -Seals the top of the cylinders
-Contains intake and exhaust valves
What is the compression ratio range in the Variable-Compression Turbo (VC-Turbo) engine?
8:1 to 14:1
What does a crankshaft do? Converts linear motion from the pistons into rotating motion
What helps to give the MR16DDT 4-cylinder engine the power of a larger engine? Direct
Injection Gasoline and turbocharging
, What are the benefits of Nissan's Dual Injector System? -More fuel-efficient than single
injector systems
-Helps increase horsepower and torque
What are the advantages of the compacted graphite iron (CGI) cylinder block in the Cummins®
V8 diesel engine compared to traditional iron? -Lighter
-Stronger
How does Nissan's Dual Injector System compare to single injector systems? -Delivers a
finer spray
-Creates a wider fuel injector spray pattern
What are the advantages of supercharging? -Relatively small fuel economy penalty
-Increased horsepower and torque across the complete engine operating range
-Immediate throttle response
