PorterFowlerRonaldRamageEnglishIVJanuary8, 2018Diesel Mechanics and TechniciansThroughoutthe world of vocational careers, many people choose the path of a dieseltechnician. “In The United States, approximately 257,906 members of thepopulation are diesel mechanics.”(EMSI) These people have dedicated theircareers to the maintenance and repair of vehicles that possess an engine thatburns diesel fuel.
“A diesel mechanic is involved in tasks related tomaintenance and repair of industry equipment and heavy vehicles. All equipmentrunning on a diesel engine is primarily maintained by these individuals. Thismay include power plants, farming equipment and oil rigs as well.” (mindspark).Manypeople may ask themselves, “What does it take to become a diesel mechanic?” TheAdvanced Technology Institute writes, “Students who aspire to be dieseltechnicians can expect to attend nineteen months or around seventy-five weeksto complete a high quality, rigorous course in diesel technology from a goodschool” (Advanced Technology Institute). Many people who become dieselmechanics usually gain their credentials from a technical or vocational school.These diesel technology courses most often offer students with a fair balancebetween hands-on training and classroom time, allowing every student a equalopportunity to learn.
According to www.rmw.org,”The average cost of in-state tuition is $2,740. There are 2,375 automotiveprograms offered in the United States, which makes it the most widely offeredprogram of the ones offered by most trade schools. These programs teach studentshow to diagnose, maintain and repair many different kinds of vehicles, andprovide hand-on experience with relevant automotive technology. The wideavailability of diesel mechanic programs, and demand for graduates, is mostlikely keeping tuition prices down”(Sorrentino).Dieselmechanic wages vary around the country and are affected by many factors such asstate minimum wage laws, company salary, and position of employment.
Accordingto www.bls.gov, “The median annual wage for diesel service technicians and mechanicswas $45,170 in May 2016.
Many diesel technicians, especially those employed bytruck fleet dealers and repair shops, receive a commission in addition to theirbase salary. Most diesel technicians work full time. Overtime is common, asmany repair shops extend their service hours during evenings and weekends.
Inaddition, some truck and bus repair shops provide 24-hour maintenance andrepair services” (U.S. Department of Labor).
Thejobs of diesel mechanics and technicians differ greatly from the jobs ofregular automotive mechanics simply due to the fact that workers in each careerfield specialize in a different type of engine. Diesel engines are profuselydifferent from normal engines, not only because different fuel is required torun each motor, but also because the two engines have different parts and usedifferent forms of combustion. “Gas and diesel engines are the two engineconfigurations that rule the road. While both are internal combustion engines,meaning that the fuel and air mixture is compressed internally through theengine’s cylinders, there are some differences in the mechanics between the twoengine types, and aspiring automotive and diesel technicians need to understandthe difference.
Both diesel and gas engines use an internal combustion method.This means that no matter if you have a diesel engine or a gas engine, yourfuel in the engine’s cylinders will ignite and drive your pistons up and down,thus turning the crankshaft that leads to your vehicle’s transmission andwheels. This cycle repeats quickly, with the fuel and air being compressed andignited internally, allowing your car to move. While the overall goal of bothengine types involves turning your wheels, there’s a difference in themechanics of getting to that point when you look at diesel compared to gas.While gas engines use spark plugs to ignite the gas when the fuel and air iscompressed, diesel engines don’t use a spark plug at all. Diesel engines useextreme combustion methods to generate copious amounts of heat so thecompressed air and fuel essentially spontaneously combust on their own, knownas a compression ignition.
This type of combustion is harmful for gas engines,but diesel engines use it to their advantage” (Automotive Training Center).Throughoutthe business world, there are a profuse number of places where a dieseltechnician could become employed. These places include, but are not limited to:vehicle manufacturing companies, towing services, and autobody repair shops.These are the most common businesses that hire diesel mechanics.
Fromthe styles of diesel engines, to the different techniques used to make theseengines run, vehicle manufacturing companies such as Ford, Dodge, and Chevrolet,differ greatly from one another. Diesel engines that are manufactured by FordMotor Company are usually engines that are known as “power stoke” engines, where as diesel enginesthat are manufactured by Dodge are engines that are recognized by the name of”Cummins”, and Chevrolet manufactures a diesel engine that goes by the name of”Duramax”. “Chevrolet(GMC), Ford and Ram each offer a diesel engine option in versions of theirlight trucks. All manufacturers claim superiority over the others fromdifferent perspectives: maximum horsepower, maximum torque, best in-classhorsepower, best in-class torque, 0 – 60 acceleration times, 1/4 mile times,fuel economy, and on. Each of the three diesels are excellent engines, well-engineered,reliable, and powerful. The current version of the Duramax, known as the LML,produces 397 horsepower and 765 lb-ft of torque.
Upgrades to the latestspecification include the use of super-fast-reacting piezo-controlled injectors,allowing owners to use fuel blends with up to 20 percent biodiesel withoutvoiding their warranty or risking damage to the engine or fuel system. TheDuramax LML 6.6 liter V-8 engine is rated at 397 horsepower (296 kW) at 3,000rpm and 765 lb-ft (1,037 N·m) of torque at 1,600 rpm” (Gearheads).
Accordingto www.gearheads.org, “The 6.7-liter Cummins Turbo Diesel I-6 is available inthree versions for Ram trucks. The lowest-powered is paired with Ram’ssix-speed manual transmission, which delivers 350 horsepower at 2,800 rpm and660 lb.-ft. of torque at 1,400 rpm. The second option matches the Cummins tothe Chrysler six-speed automatic for 370 horsepower at 2,800 rpm with 800lb.
-ft. of torque at 1,600 rpm. Third, the Cummins 6.
7L High-Output TurboDiesel is paired with the Aisinsix-speed automatic transmission, the most powerful Cummins generatesbest-in-class torque of 865 lb.-ft. at 1,700 rpm. The Cummins 6.7L High-OutputTurbo Diesel is rated at 385 horsepower (287 kW) at 2,800 rpm and 865 lb·ft(1,173 N·m) of torque at 1,700 rpm” (Gearheads). Comparedto those two engines, the Power Stroke engine differs greatly. “The all-newPower Stroke V-8 engine, made its debut in 2011 models. The upgraded 2015 6.
7LPower Stroke engine produces 440 horsepower and 860 lb.-ft. of standard torque.
The Power Stroke 6.7L V-8 Turbo Diesel is rated at 440 horsepower (328 kW) at2,800 rpm and 860 lb·ft (1,166 N·m) of torque at 1,600 rpm” (Gearheads).Mosttowing companies usually have a fleet of diesel technicians at their disposal.According to www.
rita.dot.gov,”Diesel-powered vehicles accounted for about 3 percent of total auto sales inthe United States” (Chambers and Schmitt). While that statistic may not seemlike much, the number of vehicles sold year round in the United States isconsiderably high, requiring these businesses to be prepared in order to repairany vehicle. Other than these towing companies, most diesel technicians findemployment at the profuse number of auto body shops nationwide. Inconclusion, being a diesel mechanic is a wise career choice in the UnitedStates. The amount of diesel technicians employed in the U.
S. this year isalmost the highest its ever been. However, aspiring diesel mechanics have theirwork cut out for them.
Students must attend a technical or vocational schoolfor usually around nineteen months before they can become certified dieseltechnicians. Those students have to learn many things other than just how tofix something wrong with a diesel engine. They have to learn how a dieselengine works, the different types of diesel engines, and how to fix thosedifferent types of engines. Upcoming diesel mechanic students must bephysically and mentally prepared for the long road ahead of them. Works CitedMindSpark.
