Diesel Combustion
The diesel engine is an intermittent-combustion piston-cylinder device. It operates on either a two-stroke or four-stroke cycle (see figure); however, unlike the spark-ignition gasoline engine, the diesel engine induces only air into…
Price’s engine
In 1914 a young American engineer, William T. Price, began to experiment with an engine that would operate with a lower compression ratio than that of the diesel and at the same time…
Fuel-injection technology
One objectionable feature of the full diesel was the necessity of a high-pressure, injection air compressor. Not only was energy required to drive the air compressor, but a refrigerating effect that…
Development Of Diesel Engines
Rudolf Diesel, a German engineer, conceived the idea for the engine that now bears his name after he had sought a device to increase the efficiency of the Otto engine (the first…
Fuel For Diesels
Petroleum products normally used as fuel for diesel engines are distillates composed of heavy hydrocarbons, with at least 12 to 16 carbon atoms per molecule. These heavier distillates are taken from crude oil after the…
Diesel engine
Diesel engine, any internal-combustion engine in which air is compressed to a sufficiently high temperature to ignite diesel fuel injected into the cylinder, where combustion and expansion actuate a piston. It converts the chemical energy stored in the fuel into mechanical…
Slow Medium High speed diesel Engines
The term medium refers to diesel engines that operate with in the approximate speed range 250 to 800 revolutions per minute. High speed is usually 100 rpm and above, while…
What Is Aerospace Engineering?
Aerospace engineering deals with designing and building machines that fly. It is one of the newest branches of engineering, and began in the 19th century with the first experiments in…
Components and functions of IC Engines
The cylinder block is the main body of the engine, the structure that supports all the other components of the engine. In the case of the single cylinder engine the…
VALVE TIMING DIAGRAM OF TWO STROKE AND FOUR STROKE ENGINES
THEORETICAL AND ACTUAL A valve timing diagram is a graphical representation of the opening and closing of the intake and exhaust valve of the engine, The opening and closing of…
