Equipment internal combustion engines

Freeze Point Depression. The slight heat-transfer penalty incurred when an antifreeze is added to the aqueous heat-transfer fluid is necessitated by the need for increased operating temperature range in most internal combustion engines. Because most parts of the world achieve temperatures below freezing during some time of the year, an antifreeze fluid is required to keep equipment operational in these subfreezing temperatures. 

When the automobile became preeminent in the early twentieth century, it did so with good reason. Wliether the energy to power a bicycle is anaerobic or aerobic in nature, it is still minuscule in comparison to what an automobile s internal combustion engine can deliver. In the United States, almost all subcompact cars are equipped with engines that can generate 100 or more horsepower (74,600 watts), and can sustain this output all day long.

These have been developed for special uses. For example, since petroleum-based materials harm natural rubber, a grease based on castor oil and lead stearate is available for use on the steel parts of rubber bushes, engine mountings, hydraulic equipment components, etc. (but not on copper or cadmium alloys). Some soft-film solvent-deposited materials have water-displacing properties and are designed for use on surfaces which cannot be dried properly, e.g. water-spaces of internal combustion engines and the cylinders or valve chests of steam engines. 

Many times it may easier to relocate electrical equipment outside an electrically classified area rather than occur addition expense to obtain an explosionproof rating. For example most internal combustion engines are not rated for hazardous atmospheres.

Internal combustion engines (ICEs) are commonly used to drive many mechanical devices. However, they are very complex mechanical devices themselves. ICEs are used in cars, trucks, construction equipment, and many other devices. They can be fueled by gasoline, diesel fuel, natural gas, or other combustible fossil fuels. 

The carbon residue (ASTM D-189 and ASTM D-524) of a crude oil is a property that can be correlated with several other properties (Figure 2-14). The carbon residue presents indications of the volatility or gasoline-forming propensity of the feedstock and, for the most part in this text, the coke-forming propensity of a feedstock. Tests for carbon residue are sometimes used to evaluate the carbonaceous depositing characteristics of fuels used in certain types of oil-burning equipment and internal combustion engines. 

Carbon monoxide Carbon monoxide is an odorless, colorless, and toxic gas. Sources of carbon monoxide volcanic activity, internal combustion engines, unvented kerosene and gas space heaters, generators and other gasoline-powered equipment, tobacco smoke. 

Many gas-fired compressors that pump natural gas through millions of miles of pipelines are also equipped with exhaust catalysts to clean emissions at moderate conditions. Even fast-food restaurants are being equipped with catalysts to eliminate odors from the cooking process. The most widely used treatment of exhaust pollutants is that of the catalytic converter present in the exhaust manifold that cleans emissions from the internal combustion engines of gasoline- and diesel-fiieled automobiles and trucks. As modem commercial passenger jets fly above 30,000 feet there is a need to destroy the few ppm ozone that enters the airplane with make-up air to ensure passenger and crew comfort and safety. Radiators on select... 

Molded silicone rubber articles are generally utilized as seals for equipment running at high temperatures e.g. as crankshaft seals in internal combustion engines or for headlight and gearbox seals. 

Another approach is to cool and filter the gas and utilize it as an alternative fuel for internal combustion engines. Skov and Papworth, (2), described the operation of trucks, buses, and agricultural equipment in Europe with gas produced using portable wood fueled gasifiers. Gasifiers can also be used to operate diesel engines as described in (6) and (9). 

The source of power for mobile equipment should be carefully analyzed. This choice affects the gaseous emissions from engines in the equipment, and also the overall energy consumption balance of the mine. If electricity is readily available, electric or electric-assisted haulage equipment may be preferred. At high altitudes, internal combustion engines require modifications to ensure efficient and clean operation. 

Chapter 7 will describe the use of hydrogen as a transportation fuel. It will show how it can be used in automobiles with current technology internal combustion engines. It will show how hydrogen fuel cells have the potential to provide advanced automobiles with excellent performance and zero pollution. It will show that aircraft and heavy industrial equipment can be converted to hydrogen. 

Hybrid vehicles equipped with an internal combustion engine, batteries and an electric motor/generator (HTEV) is the most commonly studied and experimented. 

To date the majority of on-road traffic is performed by vehicles equipped with internal combustion engines that use fuels derived from fossil fuels. The vehicles range from passenger cars to heavy duty trucks, and the engines used are either spark ignited or compression ignited reciprocating internal combustion devices.
