diameter of a piston in a reciprocating engine such as an internal combustion engine or steam engine. The principal function of the piston rings is to form a seal between the combustion chamber and the crankcase of the engine. The goal is to prevent combustion gases from passing into the crankcase and oil from passing into the combustion chamber The three main functions of piston rings in reciprocating engines are: 1. Sealing the combustion/expansion chamber. 2. Supporting heat transfer from the piston

System This system supplies necessary air to the engine for fuel combustion. It consists of a pipe for supplying of fresh air to the engine. Filters are provided to remove dust particles from air. Exhaust System The exhaust gas is removed from engine‚ to the atmosphere by means of an exhaust system. A silencer is normally used in this system to reduce noise level of the engine. Cooling System The heat produced due to internal combustion‚ drives the engine. But some parts of this heat raise the temperature

families. An internal combustion is defined as an engine in which the chemical energy of the fuel is released inside the engine and used directly for mechanical work. The internal combustion engine was first conceived and developed in the late 1800’s. The man who is considered the inventor of the modern IC engine and the founder of the industry is Nikolaus Otto (1832-1891). Over a century has elapsed since the discovery of IC engines. Excluding a few development of rotary combustion engine the IC engines

VALVETRONIC ENGINE TECHNOLOGY 1. INTRODUCTION The automobile has been providing individual mobility for more than 100 years. This mobility is made possible first and foremost by combustion engines drawing their power from fossil energy carriers‚ which‚ even today‚ provide the foundation in generating mechanical drive power in the automobile. The primary objectives in developing drive systems are to curb fuel consumption and reduce CO2 emissions. In an effort to meet this challenge

MECHANIZATION AND TRACTORIZATION AND THEIR DIFFERENCES INTRODUCTION MECHANIZATION AND TRACTORIZATION Mechanization encompasses a wide range of technologies‚ using human and or motor power. Hence‚ mechanization involves the use of tools‚ implements and machines to improve the efficiency of human‚ time and labour. The areas of application include; land development‚ crop production‚ harvesting‚ storage and processing. Mechanization is said to provide human operators with machinery that assist them

The History of cars By Luke Geisz Today‚ we do not think much of our cars. Everyone has them‚ they’re a common object. They weren’t always like that. Cars used to be only owned by wealthy enthusiasts. They weren’t today’s enclosed‚ climate controlled‚ easy to use devices at all. In fact‚ they were incredibly hard to use. There was no standard controlling system like today’s gas/brake/clutch pedals‚ auto transmission‚ steering wheel‚ and other controlling devices. Some had a steering wheel‚ some
