Common Rail Direct Injection

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.

The main parts of Common Rail Direct Injection system are Injector, fuel supply pump, fuel filter, distribution pipe (Rail), high pressure pumps, solenoid valve, Piezo-Inline Injector, electronic control unit(ECU) and sensors.

A year before Charles and Frank made their first car, Rudolf Diesel patented the design for diesel powered combustion engine. He believed that this would revolutionize the industry, because diesel fuel harbored a higher concentration of energy per gallon (132×106 vs 155×106 joules, gasoline and diesel respectively; in terms of energy density). The problem is that the exhaust is typically dirtier due to the much oilier nature of the fuel.

You’re in the market for a new truck; you have an idea about what you want but not quite sure if you want a gasoline or a diesel engine. Well, gas and diesel engines are very similar yet different in quite a few ways.

A. A gas engine uses spark to ignite gasoline while a diesel engine uses compressed air to ignite the diesel fuel.

Between 2007 and 2015, the Dodge Cummins 6.7L trucks had a diesel rating at 350 horsepower and 650 lb-ft of torque. They were equipped with AS68RD automatic transmissions. Two more Chassis Cabs were introduced in 2008. These trucks are the workhorses that take you to and from your job, no matter how far off the path your job is. As you need more performance from your Ram, you make changes to the diesel performance parts on your truck.

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

As a result, the lubricant can be used up at a more frequent rate than in other engines. Diesel trucks, in turn, often times require lube and oil changes more frequently due to the fact that the trucks are being used for heavy-duty workloads and long-distance transporting.

Some people enjoy having a diesel engine in their car because it provides more horsepower compared to a standard fuel engine. It gives them the ability to tow things that are very heavy such as trailers and boats, and can be fuel-efficient as well. Here are a few things to consider that will keep your car’s diesel engine working great.

In 1982 General motors introduced their first diesel engine for the pickup line. The engine manufacturer that GM partnered with was Detroit Diesel. Detroit Diesel was a good choice because Detriot Diesel had a reputable name for being reliable and well built. This was GM's first attempt at a reliable consumer diesel engine GM was not aiming for a top of the line performance diesel. This engine was a 6.2 liter naturally aspirated diesel engine, this combination engine was used from 1982-1993. The 6.2 series of diesel engine was used along with the 6.5 Turbo and non Turbo renditions of the 6.5. The 6.2 was completely discontinued in 1995 but was the building block for the 6.5 Engine. The 1993 series engine used all the same engine components but the bore was changed from 3.98 inches to 4.06 this increased horsepower and torque.

Engineering: [a] diesel engine is an internal combustion engine in which the chemical energy of fuel is transformed into thermal energy of the cylinder charge, in consequence of the self-ignition and combustion of fuel in the engine cylinder after compression of the air charge in the cylinder (p1

In the application of Diesel propulsion system, it has advantages and disadvantages. The advantages are diesel propulsion is wellknown and wellunderstood and it is a dependable method of propulsion and supporting power. Engineers can easily operate the system and the training is familiar for them. Spare part and repairmen are available world wide. Diesel fuel also easy to obtain. Research and development to deal with primary and secondary method to reduce emission are being carried as a continuous programme. The disadvantages of this system are the diesel engines create

The fuel valves are controlled by the computer depending on the requirement or isolation of fuel supply. All fuel probes sensor will continue provide feedback to the computer for quantity indication.

This paper presents exergetic evaluation of single cylinder direct injection, water cooled diesel engine at varying operating conditions. Normally, first law of thermodynamics has been used to analyze the engine cycle process. However recent research indicates that the first law of thermodynamics is inadequate to study the diesel engine performance. Exergy analysis is used to determine in detail the amounts of losses in a system and locations where they occur, and the processes that cause them so the application of exergy analysis for diesel engine allows determining the sources of irreversibilities and obtaining more accurate information about engine efficiency. An Exergy-based performance analysis is based on the second law of thermodynamics that overcomes the limitation of an energy-based analysis.
