V 8 engine by kiran Under the guidance of: Prof. RITESH MULGE
Several engine layout has been developed one of which is v style engine .so why look at v8 in particular ,v8 engine is fairly compact layout for large engine sizes which were needed in order to move heavy vehicles at sufficient speed and proved to be a most popular engine layout. Abstract
A V8 engine is a V engine with eight cylinders mounted on the crankcase in two banks of four cylinders, in most cases set at a right angle to each other but sometimes at a narrower angle, with all eight pistons driving a common crankshaft. Introduction
I n its simplest form, it is basically two straight-4engines sharing a common crankshaft. However, this simple configuration, with a single-plane crankshaft, has the dynamic imbalance problems as two straight-4s, resulting in vibrations in large engine displacements. As a result, since the 1920s most V8s have used the somewhat more complex cross plane crankshaft with heavy counterweights to eliminate the vibrations. History
The v in v8 comes from the alignment of pistons. Efficient design-Perfect firing in each cylinder, low vibration. V shape made to come out from the basic hurdle of space limitation. The v in v8
The number 8 in v8 refers to the number of pistons firing within the engine. More pistons can produce additional power ,since more explosions can occur simultaneously. The 8 in V8
The V8 engine is an eight cylinder, water cooled unit comprising of cast aluminium cylinder block and cylinder heads. Set of cranks are arranged along the shaft. Each crank is attached to the piston rod. Cylinder itself forms a seal around the piston. The v8 engine cylinders are hollowed out within the engine block. Constrution
Working
Firing Order The many possible firing orders depend on the arrangement of cranks and sense of rotation. For the balancing of the force firing orders are used.
V6 engine contains 6 cylinder and v8 contains 8 cylinder. V6 engine has less power and performance compare to v8 engine. V8 engine accelerate much faster then v6. HP is high for V8 engine. v8 engine is inherently smoother then v6. v8 & v6 engine
Compact in size. Less vibration. Perfect firing. High performance. Advantages

There have been many improvements to the internal combustion engine over the past century, engines are now smaller, more efficient, more powerful, produce less emissions and are more reliable. The V8 configuration remains a popular choice, as a compact layout for powerful saloons and sports cars, while modern restrictions means the sound is now somewhat muted, the classic sound remains, which is the main appeal from the consumer end.
