Kinetics of pollutant formation and destruction in combustion

Cost, environmental, and performance issues coupled with legislative changes, new engine oil requirements, and technology development for exploration of space and the oceans are changing the lubrication additive market. Reflecting how the need for new applications drives the development of new lubricant additives, Lubricant Additives: Chemistry and

The greenhouse effect, thought to be responsible for global warming, is caused by gases accumulating in the earth's atmosphere. Carbon dioxide, which makes up half of the gas accumulation problem, is produced during respiration and combustion processes. This paper provides an outline of the carbon cycle for rapeseed oil-derived fuels. Plant processes, fuel chemistry and combustion are examined with respect to carbon. A diagram is presented to interpret the information presented graphically. A comparison of carbon dioxide emissions from the combustion of rapeseed oil biodiesel and petroleum diesel is made. Complete combustion converts hydrocarbon fuels to carbon dioxide and water. The carbon cycle consists of the fixation of carbon and the release of oxygen by plants through the process of photosynthesis, then the recombining of oxygen and carbon to form CO 2 through the processes of combustion and respiration. The carbon dioxide released by petroleum diesel was fixed from the atmosphere during the formative years of the earth. Carbon dioxide released by biodiesel is fixed by the plant in a recent year and is recycled. Many scientists believe that global warming is occurring because of the rapid release of CO 2 in processes such as the combustion of petroleum diesel. Using biodiesel could reduce the accumulation of CO 2 in the atmosphere.

A mathematical model of a four-stroke spark-ignition engine has been developed for application to dynamic engine control The model responds to throttle, air/fuel, EGR, spark advance, and load torque inputs to provide manifold pressure, net torque, and engine speed outputs The dynamic aspects of the model are due to time delays and integration Nonlinear relationships are incorporated to predict engine performance over a broad operating range

Dual-Fuel Diesel Engines

This standard text for the automotive industry explains in detail the fundamentals of emission formation and control for gasoline and diesel engines. These concepts can be applied to other combustion systems, such as gas turbines and stationary power plants. Topics of discussion include: combustion in homogeneous mixtures; effect of design and operating variables on gasoline engine exhaust emissions; hydrocarbon evaporation emissions; diesel engine combustion emissions and controls; emission instrumentation; and automotive exhaust emission testing. 200 references, 197 figures.
