A phrase that we often hear from customers who send their trucks for repair is, “This is a diesel engine; the problem should be easy to diagnose.” The right part about that statement is that the customer ¬realizes that he has a diesel engine. Simple operation, high reliability, high thermal efficiency and low fuel consumption are few key reasons for success of Diesel engines and its varied application from land based automotive and power generation to marine propulsion applications in deep sea. Engine’s continuous availability is a crucial aspect especially in transportation sector where movement of trucks and ships depends solely on the operation without any breakdown.
This project is limited and focused on diagnosis of fuel injection system of diesel engines of Scania Trucks and buses only. The approach is to first investigate methods of fault isolation and detection of faulty component with corresponding fault mode on similar systems. Later the most optimum method to deal with statistical and experimental data set will be used to create a diagnostic model. The data is collected from service reports over the past years and various experiments done on major components of fuel injection system. With this diagnostic model, the prediction of faulty component will become easier, less time consuming and economical, thus increasing the operational time of trucks with reduced downtime.

In 2002 a joint project between International Navistar and the Ford Motor Company was born. “The goal of this project was to create an engine that was fuel efficient, emission compliant and would be able to outperform all of the competition” (Banks Power). With over 2 million ford super duty’s equipped with the 7.3l Powerstroke engine on the road, the new engine would have big shoes to fill. The engine that was to replace the outdated, underpowered and overall inadequate 7.3l Powerstroke was the International Navistar 6.0l turbo diesel.
The Cummins diesel engine was manufactured in the year 1919 by its creator Clessie Cummins. The Cummins was put in a variety of vehicles and the most common are in the dodge ram 2500, 3500, 4500, and 5500 series rams. It is also put into more heavy-duty trucks such as Peterbilt semis. The reason people choose Cummins over Chevy’s Duramax or Ford’s Powerstroke is because Cummins’ are built to last longer meaning they can go more hours without maintenance. The Cummins diesel engines have several different designs, and a number of different models, and assembling one takes money, time, effort, and knowledge.
Diesel is going to be the fuel that will control the world just like gasoline is today. Clean diesel is something that seems unreachable but it is closer than people think. Diesels now are Cleaner than ever and it it going to out do any other form of power for cars. Although other fuels and forms of power produce no emissions, diesel engines can be made to produce less harmful pollutants and be more efficient. There may be a few negative characteristics about diesel engines. But, the positive characteristics that they have out weight the bad things about them. To keep the diesels clean the process of how they work needs to be known.
Gas engines are mainly used by the individual in personal vehicles whereas diesels are very popular in the commercial and industrial fields. Diesel engines are used by the navy in their ships and by the army in their tanks and big trucks. Some of the main reasons for choosing this engine are
The vision of the company is presented to give an idea of what Diesel’s mission is. Also the aims and objectives of Diesel to ensure this vision is realised are defined. Factors affecting the organisation are discussed, using SWOT analysis and PESTEL factors.
2. “ Because of their efficiency and durability, diesel engines have become the standard in powering trucks and buses. Other heavy vehicles and mobile equipment, including bulldozers and cranes, are also powered by diesel engines, as are many commercial boats, and some passenger cars and trucks. Diesel technicians handle many kinds of repairs. They may work on a vehicle’s electrical system, make major engine repairs, or retrofit exhaust systems with emission control systems to comply with pollution regulations. Diesel engine maintenance and repair is becoming more complex as engines and other components use more electronic systems to control their operation. For example, fuel injection and engine timing systems rely
Did you know that diesel engines are responsible for delivering everything that you use on a daily basis? I think that being a diesel service technician would be a good occupation for me because I enjoy working with my hands and because the way that engines work fascinates me. I want to use this in a field that allows me to use my skills and knowledge, as well as offering opportunities for improvement. As an ASE certified diesel service technician, I will have a well-paying job that interests me and allows me to use my skills and knowledge to my advantage while also improving myself. This paper will explore the job description, requirements, and salary expectation of an ASE certified diesel service technician.
As our technology and economy increases more companies and every day drivers have started converting to diesel engines. Diesels provide great mileage, the “fuel is efficient and energy dense.” (Pros and Cons) In addition, there are less tune ups and the engines are built more ruggedly to withstand the higher compression. With the increase of diesel engines this opens up more job opportunities with the need of more workers. For one to meet the requirements to become a diesel mechanic they need to have formal training, adapt to the work environment, meet the skills and traits and understand the outlook and are accepting to the pay.
Ford F-250 6.7 Power-stroke is the greatest diesel on the market. Ford has been making diesel trucks since the 1960's. Ford has the best diesel on the market because of the capabilities, materials, durability, modifications and safety features.
A diesel mechanic does anything that involve with a diesel engine. For Cummins Inc. I would be working with the filtration system, regeneration system, emission solutions, and turbo technologies. Most of this is main parts of a diesel engine. I haft to understand how
The performance of a diesel truck and a gas burner truck are very different, but either one can be advantageous depending on its use. The horsepower of the diesel truck averages around 360, but can easily be modified with plug and go tuners that can increase HP to over 500 while the gas burner is at an all time high around 420 HP in the new v8 engines. The gasser may prevail in horsepower, but the diesel dominates in torque. The gasser tops out around 460 lb/ft while the diesel blows it away at 765 lb/ft. The towing capacity is the game changer for the diesel truck compared to the gasser. The gasser starts to struggle around 12,000 pounds at high RPMs, but the diesel is still running smoothly around 17,500 pounds. It is hard for the gasser’s towing power to beat the towing power of
In today’s motorized life , It’s difficult to live without motor (Engines) and the main source of it’s input power is fossil fuels & partly electric power. In future these fuels or electricity may not be available widely as they are non renewable energies. So, it may be difficult to use engine with the fuels.
The world we live in is surrounded by diesel engines. They are on the freeways, railways, airways, and are one of the leading electricity producers in the world. They are also becoming more popular in automobiles. These engines are efficient and reliable and they are getting very sophisticated. However, the physics behind these engines has not changed.
Continued quality issues with our DGS, a critical part within LongXi’s Small Multi-Cylinder Diesel Engine has resulted in breakdown, engine failure and loss production at several customers. Customer complaints are increasing and we need to react to and eliminate our quality concerns. We must develop ways to improve quality in house. Our QC group is well established therefore we are recommending that we collect and analyze data relative to why the DGS is failing and
Unlike petrol engines, diesel engines don’t need ignition system. Due to the inherent property of diesel, combustion will be automatically effective under a certain pressure and temperature combination during the compression phase of Otto cycle. Normally this requires a high compression ratio around 22 : 1 for normally aspirated engines. A strong thus heavy block and head is required to cope with the pressure. Therefore diesel engines are always much heavier than petrol equivalent.
