standards of skills are needed to be a successful diesel technician? In order to be an outstanding diesel mechanic you need to have mechanical and technical skills. Diesel mechanics job is to break down an engine and build it back together. They must well know the parts of an engine‚ the transmissions‚ air intake and the exhaust and brake systems. Technical skills include connecting computerized diagnostics equipment to diesel engines to analyze

Piston Engines Picture a tube or cylinder that holds a snugly fitting plug. The plug is free to move back and forth within this tube‚ pushed by pressure from hot gases. A rod is mounted to the moving plug; it connects to a crankshaft‚ causing this shaft to rotate rapidly. A propeller sits at the end of this shaft‚ spinning within the air. Here‚ in outline‚ is the piston engine‚ which powered all airplanes until the advent of jet engines. Pistons in cylinders first saw use in steam engines. Scotland’s

Turboprop engines Turboprop engines are a type of aircraft powerplant that use a gas turbine to drive a propeller. The gas turbine is designed specifically for this application‚ with almost all of its output being used to drive the propeller. The engine’s exhaust gases contain little energy compared to a jet engine and play a minor role in the propulsion of the aircraft. The propeller is coupled to the turbine through a reduction gear that converts the high RPM‚ low torque output to low RPM‚

confused with the catapult. The Mangonel is believed to be invented by the Romans in 400BC. During the Medieval age the engine was used most by the French. It’s named Mangonel because the Latin word manganon means “an engine of war”. Mangonels were referred to as scorpions because the arm of the engine was like the tail of the animal. The Mangonel wasn’t as accurate as other siege engines but did go a greater distance. The Mangonel has a long arm attached to a bowl like bucket. The base had wheels so

WANKEL ENGINE The Wankel engine‚ invented by German engineer Felix Wankel‚ is a type of internal combustion engine which uses a rotary design to convert pressure into a rotating motion instead of using reciprocating pistons. Its four-stroke cycle takes place in a space between the inside of an oval-like epitrochoid-shaped housing and a rotor that is similar in shape to a Reuleaux triangle but with sides that are somewhat flatter. This design delivers smooth high-rpm power from a compact size. Since

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

Ans To become a global firm‚ ideally‚ company should be taking gains of R&D‚ production‚ marketing and financial advantages in its costs and reputation that are not available purely to domestic competitors. It minimizes importance of national boundaries and develops “transitional” brands. It raises capital‚ obtains materials and components
