Diesel Mechanics and Technicians
Throughout the world of vocational careers, many people choose the path of a diesel technician. “In The United States, approximately 257,906 members of the population are diesel mechanics.”(EMSI) These people have dedicated their careers to the maintenance and repair of vehicles that possess an engine that burns diesel fuel. “A diesel mechanic is involved in tasks related to maintenance and repair of industry equipment and heavy vehicles. All equipment running on a diesel engine is primarily maintained by these individuals. This may include power plants, farming equipment and oil rigs as well.” (mindspark).
Many people may ask themselves, “What does it take

to become a diesel mechanic?” The Advanced Technology Institute writes, “Students who aspire to be diesel technicians can expect to attend nineteen months or around seventy-five weeks to complete a high quality, rigorous course in diesel technology from a good school” (Advanced Technology Institute). Many people who become diesel mechanics usually gain their credentials from a technical or vocational school. These diesel technology courses most often offer students with a fair balance between hands-on training and classroom time, allowing every student a equal opportunity to learn. According to www.rmw.org, “The average cost of in-state tuition is $2,740. There are 2,375 automotive programs offered in the United States, which makes it the most widely offered program of the ones offered by most trade schools. These programs teach students how to diagnose, maintain and repair many different kinds of vehicles, and provide hand-on experience with relevant automotive technology. The wide availability of diesel mechanic programs, and demand for graduates, is most likely keeping tuition prices down”(Sorrentino). Diesel mechanic wages vary around the country and are affected by many factors such as state minimum wage laws, company salary, and position of employment. According to www.bls.gov, “The median annual wage for diesel service technicians and mechanics was $45,170 in May 2016. Many diesel technicians, especially those employed by truck fleet dealers and repair shops, receive a commission in addition to their base salary. Most diesel technicians work full time. Overtime is common, as many repair shops extend their service hours during evenings and weekends. In addition, some truck and bus repair shops provide 24-hour maintenance and repair services” (U.S. Department of Labor). The jobs of diesel mechanics and technicians differ greatly from the jobs of regular automotive mechanics simply due to the fact that workers in each career field specialize in a different type of engine.
Diesel engines are profusely different from normal engines, not only because different fuel is required to run each motor, but also because the two engines have different parts and use different forms of combustion. “Gas and diesel engines are the two engine configurations that rule the road. While both are internal combustion engines, meaning that the fuel and air mixture is compressed internally through the engine’s cylinders, there are some differences in the mechanics between the two engine types, and aspiring automotive and diesel technicians need to understand the 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, your fuel 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 and wheels. This cycle repeats quickly, with the fuel and air being compressed and ignited internally, allowing your car to move. While the overall goal of both engine types involves turning your wheels, there’s a difference in the mechanics 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 is compressed, diesel engines don’t …show more content…
use a spark plug at all. Diesel engines use extreme combustion methods to generate copious amounts of heat so the compressed air and fuel essentially spontaneously combust on their own, known as a compression ignition. This type of combustion is harmful for gas engines, but diesel engines use it to their advantage” (Automotive Training Center). Throughout the business world, there are a profuse number of places where a diesel technician 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. From the styles of diesel engines, to the different techniques used to make these engines run, vehicle manufacturing companies such as Ford, Dodge, and Chevrolet, differ greatly from one another. Diesel engines that are manufactured by Ford Motor Company are usually engines that are known as “power stoke” engines, where as diesel engines that 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 their light trucks. All manufacturers claim superiority over the others from different perspectives: maximum horsepower, maximum torque, best in-class horsepower, 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 latest specification include the use of super-fast-reacting piezo-controlled injectors, allowing owners to use fuel blends with up to 20 percent biodiesel without voiding their warranty or risking damage to the engine or fuel system. The Duramax LML 6.6 liter V-8 engine is rated at 397 horsepower (296 kW) at 3,000 rpm and 765 lb-ft (1,037 N·m) of torque at 1,600 rpm” (Gearheads). According to www.gearheads.org, “The 6.7-liter Cummins Turbo Diesel I-6 is available in three versions for Ram trucks. The lowest-powered is paired with Ram’s six-speed manual transmission, which delivers 350 horsepower at 2,800 rpm and 660 lb.-ft. of torque at 1,400 rpm. The second option matches the Cummins to the Chrysler six-speed automatic for 370 horsepower at 2,800 rpm with 800 lb.-ft. of torque at 1,600 rpm. Third, the Cummins 6.7L High-Output Turbo Diesel is paired with the Aisin six-speed automatic transmission, the most powerful Cummins generates best-in-class torque of 865 lb.-ft. at 1,700 rpm. The Cummins 6.7L High-Output Turbo 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). Compared to those two engines, the Power Stroke engine differs greatly. “The all-new Power Stroke V-8 engine, made its debut in 2011 models. The upgraded 2015 6.7L Power 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) at 2,800 rpm and 860 lb·ft (1,166 N·m) of torque at 1,600 rpm” (Gearheads). Most towing 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 in the United States” (Chambers and Schmitt). While that statistic may not seem like much, the number of vehicles sold year round in the United States is considerably high, requiring these businesses to be prepared in order to repair any vehicle. Other than these towing companies, most diesel technicians find employment at the profuse number of auto body shops nationwide. In conclusion, being a diesel mechanic is a wise career choice in the United States. The amount of diesel technicians employed in the U.S. this year is almost the highest its ever been. However, aspiring diesel mechanics have their work cut out for them. Students must attend a technical or vocational school for usually around nineteen months before they can become certified diesel technicians. Those students have to learn many things other than just how to fix something wrong with a diesel engine. They have to learn how a diesel engine works, the different types of diesel engines, and how to fix those different types of engines. Upcoming diesel mechanic students must be physically and mentally prepared for the long road ahead of them. Works Cited MindSpark.

Here's 8 Questions to Ask Before Enrolling into a Diesel Mechanic School. 1. What is the difference between a. and a. Has the school been assessed by NATEF (which remains with the National Automotive Technicians Education Foundation)? Note: When I say NATEF realize that their essential concern is to enhance the nature of auto expert preparation programs all through the U.S. by means of deliberate confirmation accreditation. NATEF is run by a 14-member trustee board that is selected by the ASE Board.
Diesel mechanics fix and maintain every part associated with the diesel engine. There are many different branches of diesel technology which can include construction and farm equipment, over the road trucks, light duty pickups and stationary engines to name a few. A mechanic must be familiar with major brands of engines like Cummins and Cat. They can perform simple tasks of swapping out a bad component to completely overhauling an engine. The median pay for mechanics is “$42,320 per year or $20.35 per hour (United States).” When overtime hours are reached mechanics receive one and a half times pay for work performed. Negative parts of the job are the amount of overtime hours, the dirtiness of the work, and the cost of tools. Positive parts of the job are overtime pay, hands on, and traveling for work. The job outlook for growth in the diesel field “is projected to grow 9 percent from 2012 to 2022, about as fast as the average for all occupations (United States).” The field of diesel mechanics is still growing today and will continue for a...
Today there are currently 250,800 diesel mechanics employed and there expected to rise be 9% by 2022. Because diesel burns cleaner and the worlds trying to go green and is used to transport goods all
Diesel mechanics are practically the backbone of this country. Everyone knows that things are delivered via eighteen wheelers these days occasionally they need to be repaired and have maintenance done to them. When that happens who’s there to save the day? DIESEL MECHANICS that’s who! You’re about to learn what it takes to become a diesel mechanic and what you’ll make when you are one.
Cummins has a history of innovation beginning in 1919 when it was founded and produced its first diesel engine, a 1.5 to 8 horsepower model used to power pumps. In 1929, a Cummins engine powered the first diesel-powered U.S car. The company continued to advance in the diesel engine and power generation industry, and in 1958 Cummins Filtration was started to meet the high-performance requirements of Cummins diesel engines (Cummins Inc.). In 1985, Cummins introduced aerodynamic contours to Class 8 trucks years ahead of its time. This new shape greatly reduced air flow drag and, combined with a lightweight engine, attained up to 20 percent higher fuel efficiency than similar vehicles at the time. In 1999, Beijing Public Transit launched a fleet of 300 buses with Cummins B5.9 engines to improve city air quality, being the first clean, alternative fuel fleet in Asia and remains the largest in the world, with more than 3500 Cummins Westport natural gas powered buses (Cummins Inc.). These are just a few examples demonstrating a history marked by improvement and innovation of new technologies in order to reduce emissions and increase efficiencies for the benefit of the environment.
The diesel engines combustion process is a little different than the typical gasoline engine. A couple main things that diesel engines have that gasoline engines do not are, carburetors and spark plugs. Unlike a gasoline engine, air is first allowed into the cylinder rather than a fuel and air mixture. Once the air is compressed it creates a source of heat, then a mist of fuel is injected to start the combustion process which then creates the energy. Since diesel engines do not have spark plugs they are able to take in larger amount of fuel, this obviously means there will be more power and will guarantee better efficiency. Another thing that is very important is that diesel tends to be a better lubricant than gasoline, being that it is a better lubricant there will be less friction which will generally increase the life of the engine (Woodford). Diesel engines operate at slower speeds than gasoline engines, therefore diesel engines tend to have longer lifespans than gasoline
As I thought about it, I found great pride in becoming a diesel mechanic. Before writing this esay I just liked what they got to do, but now I see how infulential they are to everybody. Diesel mechanics are purtinent to todays economy and our way of life. I know that not every kid wishes to become a mechanic one day, but that is why I admire their line of work. In a way they are the unsung heros of the road. I say this only to emphasis how important they are to me personally. If a semi has an issue while driving down the road many people can be hurt by this error. Lets keep the roads safe with smart mechanics behind the
