DIESEL ENGINES
100
harmfull gasses created by engines
what are emissions
100
what does EPA stand for?
What is Environmental Protection Agency

what makes a diesel better then a gas engine?
heavy duty parts higher torque gain during lugging high efficiency long lifespan (200,000 miles plus)
200
"soot" or black smoke
What is diesel particulate matter
200
what does the EPA do?
implements Federal laws designed to promote public health by protecting our Nation's air, water, and soil from harmful pollution.
200
what makes a gas engine better then a diesel ?
typically higher RPM faster acceleration lighter weight lower compression lighter duty (cheeper parts) cheeper maintenance
300
a toxic odorless tasteless gas created in combustion engines
What is carbon monoxide
300
how does the EPA effect the diesel industry?
by setting goals and guidelines called TIERs they regulate the emissions of on and off road diesel engines that are being built and the engines must meet these standards to be sold in the USA
300
how do diesel engines ignite their fuel
when diesel fuel (and air) is properly atomized and highly compressed it creates enough heat and pressure to cause the fuel mixture to explode within the cylinder pushing the piston downward and creating torque
400
true or false Diesel engines are all ways cleaner then gasoline engines
FALSE!
400
what are the 4 TIERS for diesel engines whats the difference?
tier 1 tier 2 tier 3 intrim tier 4 full tier 4 http://www.government-fleet.com/fc_images/articles/M-emissionsgraphic-1.jpg

what tuning is necessary to achieve maximum efficiency from a diesel engine?
TIMING TIMING TIMING proper injection atomization fuel metering air induction ECU Calibration
500
how can diesel emissions be reduced?
EGR diesel exhaust fluid particulate filter precise diesel engine tuning
500
how do emmisions standards effect performance? doesn't SOOT give you more power????
A properly tuned diesel engine that meets can meet emisions standards has the same and usually much MORE power then a "dirty diesel" that is dumping to much fuel into the cylinders and in turn out the exhaust pipe.
500
why is efficiency of a diesel engine important?
longevity of equipment maximum fuel efficiency minimal emission output
