With a tougher legislation and the need for cleaner and more economical engine operation, it has become increasingly more difficult to design an engine which can be compatible with the new requirements. Engine Management System (EMS) is an integrated electrical system which can achieve this by closely monitoring the operation of an engine. It monitors and controls all the key functions of the engine and the exhaust aftertreatment system for a cleaner, more efficient and high power output operation. EMS controls key systems such as fuel injection, turbocharging and exhaust gas recirculation. 1 Air subsystem Air subsystem is a key factor in determining torque output and, engine performance. More the cylinder charged with clean air, the higher the maximum possible engine power output. Figure 1 shows the main components of an air subsystem: The air filter prevents particles and dust from entering the engine in order to reduce wear in the bearings, piston rings, cylinder walls. It also prevents higher fuel consumption and pollutant emissions which result from particles in the engine. Then supercharging/turbocharging is utilised to increase the power output from the engine by drawing pressurised air under force into the cylinders thus higher air mass. This has a great effect in reducing the fuel consumption and exhaust-gas emission rates. Compressing the air by the turbocharger, leads to excess heat which has a negative effect on cylinder charge. Downstream of the
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 The engine that was to replace the outdated, underpowered and overall inadequate 7.3l Powerstroke was the International Navistar 6.0l turbo diesel.
Question #3: How do you see YOUSELF fitting into this career? Answer: I fell that I will fit in to this career as I have worked as a life guard which touches on the very basics of swimming and pool life safety. I enjoyed being with people and helping when needed. I also enjoyed the management side overseeing employees, and daily responsibilities. Question: What personality characteristics are required? Answer: A desire to serve people, emotionally stable and clearheaded. Inspire confidence with levelheadedness and good judgment. Good physical condition,
After many years of trial and error, a combination of inventors and engineers developed a practical, effective internal combustion engine that greatly affected the world. This paper will give opposing views on the background and analyze the effects it had on transportation and the environment.
The continuing rotation of the crankshaft drives the piston back up, ready for the next cycle. The piston moves in a reciprocating motion, which is converted into circular motion of the crankshaft, which ultimately propels the car. Gas engines usually have about the same about of horsepower as they do torque. The diesel engine usually has twice as much torque as it does horsepower, thus it is the better hill climber and load carrier.
As you drive, air rushes past your car. It hits the front of your car and the intake, and this cold air is forced to the engine. As a combination, the turbo and intake greatly improve power and speed.
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
An automobile requires routine maintenance, including checking the air filter and changing it when required. A clogged air filter will overwork the engine resulting in reduced performance, gas mileage and causing unnecessary wear on the engine. A clean air filter also helps the air conditioning to function more efficiently.
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.
When nitrous oxide is used in cars and rockets, it vaporizes, causing a significant cooling effect on the intake air. You increase the density of the air when the intake air pressure is reduced. This provides even more oxygen in the cylinder which is a good thing.
Contain 4 main components, Compressor housing, compressor wheel, Turbine housing, along with a turbine wheel. Exhaust gas enters the system through the compressor housing while the air flows over the compressor wheel it causes a chain reaction which results in a counterclockwise rotation of the turbine wheel. This rotation is the stage when exhaust gas turns to air pressure. The air pressure is returned to the engine through a waste-gated return hose/line. The pressurized air is then interchanged with combustible diesel fuel and ignited. The bigger the turbo charger is allows more mass air flow which results in more fuel being burned all this combined equals a greater amount of horsepower
Clean air filters keep your diesel truck running optimally; they prevent the contamination of the engine. It is recommended that you change the air filter every fifty thousand miles.
The growing dependence of many countries, especially the USA and Europe on the imported oil and the daily increase of oil price and the heightened concern on the global warming and the environmental pollutions which has forced many car manufacturing companies to study the new and innovative techniques in solving this very important issue.
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.
That covers the basic function of an engine fron intake to exhaust. Next we will explore the relationship of Horsepower vs Torque.
Direct injection means injecting the fuel directly into the cylinder instead of premixing it with air in separate intake ports. That allows for controlling combustion and emissions more precisely, but demands advanced engine management technologies.
