The Internal Combustion Engine Essay

852 words - 3 pages

The internal combustion engine has become an integral part of the lives of every person on earth. They’re the devices that have allowed us to cross continents reliably, generate electricity in remote areas and fly around the world in a matter of hours. All these engines do is burn fuel and convert its energy into work. It’s these heat engines that have really changed the world. However the convenience they bring has come at a great cost. The major problem with the internal combustion engine is the environmental damage it has caused. It is only now we are beginning to realise the full extent of this damage.
     In the mid-seventies basic steps were taken to reduce the pollution caused by cars, which of course at their heart is an internal combustion engine. The first and most obvious source of pollution from cars is the Exhaust pipe. Exhaust emissions contain carbon monoxide, unburned hydrocarbons and oxides of nitrogen. Also a small amount of solid matter, or particulates, is emitted in the form of lead from the tetraethyl lead used in fuel to increase its octane rating. It was found that these pollutants were having an adverse effect on the environment and in extreme cases were actually causing visible ‘smog.’ But exhaust emissions in pre-70’s cars were only accounting for 55% of automotive air pollutants. Another major source was emissions of hydrocarbons from the engine’s crankcase. They occurred because during combustion there is a small amount of gas ‘Blow-By’ past the rings, consisting mainly of unburned fuel. This would enter the crankcase and it would then be simply vented into the atmosphere. One of the earliest emission control requirements was to prevent this by using ‘Positive Crankcase Ventilation’ or P.C.V. This is where this unburned fuel would be routed into the inlet manifold for burning. The last form of pollutant that was causing problems was fuel evaporation. This is where fuel would evaporate and then would be allowed to escape through a vented cap. This was stopped by venting it, in most cases, to a charcoal canister where it would be stored to be burnt later in the combustion process. The Australia Design Rule 27A (ADR-27A) was introduced in July 1976. This was the first major emission control requirement in Australia. It addressed the issues of vehicle emissions and car manufactures were required to abide by it in order to reduce the emissions of their cars.
     The world is learning to a greater extent that vehicle pollution is a real problem and great...

The block and heads can go to a machine shop to be hot tanked. A hot tank is an acid bath that removes contaminants and most paint from the metal. The parts stay in the hot tank for several hours as the caustic solution circulates around (“Cleaning Engine Parts”). Once clean, the parts can be inspected for wear

Theoretical Approach In general, the efficiency of engine calculated by the first law of thermodynamics is the ratio of useful work and the energy input. In the internal combustion engine, useful work is the engine output power measured by engine dynamometer, while the energy input can be specified from the fuel consumption rate. The figure 1 shows the energy balance according to the 1st law.
