a lot of potential areas where chemical sensors play a key role in innumerable processes concerning to functioning and safety in manufacturing plants ‚ transport‚ aerospace‚ automobiles ‚ combustion engines which are a few applications of mechanical engineering concepts. The monitoring and control of combustion-related emissions is a top priority in many Industries. The real challenge is not only to develop highly sensitive and selective sensors‚ but to maintain long-term stability in such aggressive

do not realize the downside of these cars. For instance‚ did you know that average battery cost for electric cars is between $18‚000 and $20‚000? Also‚ these cars produce significant more amounts of sulfur dioxide compared to traditional internal combustion engines‚ and what about the factories that burn billions of tons of coal everyday to produce electricity to charge these cars? Yes‚ these cars do produce little carbon dioxide directly‚ but the main source of pollution comes indirectly from the

negative effects that oil has had on the environment have been a major factor in the manufacturing of cars that contain hydrogen fuel cells. Recently‚ multiple car dealerships have begun manufacturing cars that contain replacements of the internal combustion engine with hydrogen fuel cells. Jim Motavalli‚ editor of E. Magazine‚ writes‚ “A hydrogen car emits no pollution or global warming gases‚ aside from what might have resulted from producing the hydrogen itself‚” (105). This is what scientists have

methods. The gasoline engine in a conventional car is less than 20% efficient in converting the chemical energy in gasoline into power that moves the vehicle‚ under normal driving conditions. ("Hydrogen Fuel Cells.") Hydrogen fuel cell vehicles use electric motors and are much more energy efficient. They use 40-60 percent of the fuel’s energy. This would correspond to more than a 50% reduction in fuel consumption when compared to a conventional vehicle with an internal combustion engine. Fuel cells are

from the combustion of sulphur-containing fossil fuels such as coal for domestic and industrial purpose.[i] Industrial development and the use of fossil fuels have affected the world climate adversely. In Nigeria epileptic power supply has brought about the use of diesel and petrol powered generators virtually in all homes 2. The transport induced environmental pollution in Nigeria‚ is further compounded by recent influx of motorcycles and tricycles‚ most of which have 2-stroke engines. Equally

is to know the feasibility of the hybrid car against the petrol car. The procedure adopted for the comparative analysis is to do life cycle costing of both the engines by considering the cost‚ benefits‚ maintenance and repairs for both the engines. The weight scoring model was also developed to analyze the feasibility of both the engines on the grounds of terms like safety‚ comfort‚ emissions and incentives. After completing the comparative analysis the life cycle costing model and the weight scoring
