Fuel injection in diesel engines [edit] Mechanical and electronic injection Older engines make use of a mechanical fuel pump and valve assembly which is driven by the engine crankshaft‚ usually via the timing belt or chain. These engines use simple injectors which are basically very precise spring-loaded valves which will open and close at a specific fuel pressure. The pump assembly consists of a pump which pressurizes the fuel‚ and a disc-shaped valve which rotates at half crankshaft speed

The four stroke engine includes various parts such as‚ intake‚ compression‚ combustion‚ and exhaust stroke. The term stroke is used to describe the full travel of the piston along the cylinder‚ in whichever direction. A four stroke engine is one of the most common engine types. It powers almost all trucks and cars today. Each one corresponds to one full stroke of the piston. All four of these parts help make the engine function as a whole. The first stroke is called the intake stroke the first stroke

Parts of the marine diesel engine Below is a cross-sectional view of a Sulzer Main Diesel Engine and the names of the component parts. The starting air valve is used to lead highly compressed air to push the piston for turning the engine when starting. In this 2-stroke engine‚ the air intake and exhaust are taken into the engine cylinder liner through scavenging ports and exhaust ports. The cylinder head covers the top of the cylinder and houses the starting air valve‚ fuel valve or injector

Life was consumed by constant orders‚ labor‚ malnutrition‚ disease‚ and murder in the concentration camps. Yet somehow the human psyche in many individuals was able to endure throughout these imprisonments. Men and women were almost completely dehumanized during this genocide‚ but their psyche survived it. People had to find little things to keep themselves content and to nurture their psyche. “Humor was another of the soul’s weapons in the fight for self-preservation” (63). Humor allows a person

global warming are the cars humans drive every‚ more specifically the engines that power them. Gasoline engines are a major problem because of the emissions they put into the atmosphere; however‚ electric engines and other alternatives may prove to be the future. Gasoline engines have been powerhouses literally and figuratively for a long time. Not only

Matt Bagley English 110 Process Essay Process of a 4-stroke Internal Combustion Engine A common phrase that is heard whilst growing up is "curiosity killed the cat". This phrase might be true but; "ingenuity brought the cat back". Having a mindset in which giving up is never an option has plagued most inventors of the modern day‚ especially a high school drop out named Nikolaus August Otto‚ born in 1832. Otto was responsible for the development and improvement of the 4-stroke motor that

I asked my Dad‚ Brad Houchen‚ to come check my car and as he looked he noticed that he believed that my car was leaking oil. He did not feel comfortable letting me drive my car to campus‚ which is twelve miles away. He did not want my car to break down along the way which could lead to my engine being messed up and me missing my final. He told me to take my

HEAT ENGINE WORKING CYCLES An engine is a device which transforms one form of energy into another form. However‚ while transforming energy from one form to another form‚ the efficiency of conversion plays an important role. Normally‚ most of the engines convert thermal energy to mechanical work and therefore they are called ‘heat engines’. Heat engine is a device which transforms the chemical energy of a fuel into thermal energy and utilizes this thermal energy to perform useful work. Depending
