INTRODUCTION TO ENGINE

Engine : It acts as the power unit. The internal combustion engine is the most commonly used in automobiles. It is of two types ; (i) Spark ignition (ii) Compression ignition.         Both engines are called heat engines. A steam engine is an external combustion engine because the fuel is burned outside the engine. The principle of working of an external combustion engine is shown in the figure below. COMPARISON BETWEEN INTERNAL AND EXTERNAL COMBUSTION ENGINES      The internal combustion engine is an engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber. In an internal combustion engine the expansion of the high temperature and pressure gases, which are produced by the combustion, directly applies force to a movable component of the engine, such as the pistons and by moving it over a distance, generate useful mechanical energy.          The internal combustion engine...

FOUR STROKE PETROL ENGINE MAIN PARTS 1. PISTON 2. CYLINDER 3. CONNECTING ROD 4. INLET VALVE 5. EXHAUST VALVE 6. SPARK PLUG 7. CRANK SHAFT 8. FLY WHEEL 9. CAM SHAFT CONSTRUCTION A four stroke petrol engine have a piston, connecting rod, crank shaft, inlet valve, exhaust valve and a spark plug. The connecting rod is used to connect the piston and crank shaft. The spark plug and valves are mounted in the cylinder head. Also the valves are operated by cam shaft which is connected to the crank. In this type of engines, there would be a power stroke for every two rotations of crank shaft. It is also known as otto cycle. Each full rotation of crank having two strokes. So one stroke is  180° rotation of flywheel. A four stroke petrol engine having the following strokes. WORKING Induction stroke : The crankshaft moves the piston downwards (TDC to BDC). The inlet valve is open and a mixture of fuel and air is sucked into the combustion chamber. It is also known suction stroke. In this strok...

MAJOR PARTS OF AN IC ENGINE

ENGINE COMPONENTS 1. CYLINDER BLOCK      The cylinder block is the main body of the engine. Cylinder head is mounted on the cylinder block. It houses iniet and exhaus valves. Crank case is attached to the bottom of the cylinder block. Crank case supports the crank shaft. Oil pan is attached to the bottom of the crank case. Cylinder block contains large cylindrical holes called cylinder bore. The cylinders are accurately finished to accommodate pistons. The space above the piston inside the cylinder at TDC called the combustion chamber. Combustion of fuel inside this space, high pressure and temperature will be developed inside the cylinder. Therefore, it should be made of material which can resist high pressure and temperature (2800°C). In water jackets has around the cylinders for the circulation cooling water to absorb the temperature while running of an engine. 2. CYLINDER HEAD Cylinder head is a separate casting placed on top of the cylinder block by studs and nuts. I...
