	Nicolet Magna 560 Fourier Transform Infra Red Spectrometer
Hazardous Air Pollutants (HAPs) are measured using our Fourier Transform Infra Red (FTIR) spectrometer. The primary HAPs of interest are formaldehyde, acrolein, and acetaldehyde. Ammonia and hydrogen cyanide can also be measured. THC (up to C3) and NOx speciation are performed with the FTIR. The most important aspects of the Magna 560 FTIR spectrometer include the mercury cadmium telluride (MCT) detector, germanium-on-potassium bromide (Ge-on-KBR) beamsplitter, and an instrument resolution limit of 0.125 cm^-1 (after apodization). The instrument uses a 10 meter gas cell, which has a volume of 2 liters and utilizes zinc selenide windows.

	Engine Control and Monitoring (ECM) 4800R AFRecorder and SEGO
Equivalence ratio for stoichiometric applications can be measured in the exhaust with the Engine Control and Monitoring (ECM) AFRecorder. the AFRecorder uses a SEGO wide ranging "oxygen" sensor that responds to oxygen, hydrogen, and CO. Each individual sensor is shipped with 6 sensor specific calibration constants. The fuel gas composition (%Carbon, %Hydrogen, etc.) is entered into the analyzer, which enables accurate measurement of equivalence ratio.

	Micro GC 3000 Gas Chromatograph
The composition of fuel gas is measured with two Micro GC 3000 chromatographs, one made by Agilent and the other Varian. This analyzer utilizes a split-sample technique to achieve very fast analysis times (~50 seconds). Gas species are separated with packed columns and detected using a thermal conductivity detector. Typically the analysis is set up to determine fuel gas composition up through C6.

	PM₁₀ Cyclone Mini-Dilution Tunnel
Particulate Matter(PM) can be measured using a mini-dilution tunnel. PM is collected in a filter downstream of the PM₁₀ cyclone, which eliminates particulates larger than 10µm. Filters collect all particulate matter that passes through the cyclone. The filters are weighted before and after te test using a precision balance, accurate to 1 microgram. Labview is used for the data acquisition system, which monitors exhaust sample mass flow, dilution ratio, and system temperatures.

	Rapid Compression Machine for Chemical Kinetic Studies
The TESTEM TERCM-84 rapid compression machine simulates a single stroke of a compression ignition engine, enabling the measurement of ignition delay and speciation. The TERCM-84 contains all necessary systems to operate and control the rapid compression process and to measure experimental parameters including instantaneous displacement and position of the piston during compression. The system also enables the measurement of dynamic pressure parameters during firing compression.

	The CLD 500 System for Fast NOx Measurement
The TESTEM TERCM-84 is integrated with a Cambustion CLD500 Fast NOx chemiluminscence analyzer shown in Fig. A1(b). This unique device enables measurement of NO and NO2 with an extremely high response time of 2 ms by locating the chemiluminescence detector in a remote sample head directly at the source. The sample gas is conveyed to the detector through heated capillaries, which minimizes sample gas mixing and yields a very fast response time. The CLD500 system includes two sample heads on tripods with 10 m conduits between the instrument cabinet and the sample point. It also includes a user interface computer, low-maintenance oil-free vacuum pumps and system chassis with all the necessary power and signal conditioning. To measure NO2 and total NOx, a special sample head is included which converts NO2 to NO for subsequent chemiluminscent analysis. The NO2 converter uses a heated stainless steel method of conversion. To enable time resolved capture of in-cylinder gas from the RCM, the CLD500 interfaces directly with the RCM cylinder via the CVD500 Cambustion Sample Valve system. These systems enable direct measurement of NO, NO2 and total NOx at 2 ms intervals after the end of the rapid compression cycle.

Bio-Ester Droplet Combustion Apparatus Microgravity Drop Tower

Microgravity bio fuel droplet ignition apparatus developed by masters students.

A microgravity drop tower for fundamental combustion and fluid dynamics research has been developed to accommodate experimental test rigs from the NASA 2.2 second drop tower. The hardware for the drop tower was designed and built by several multidisciplinary teams of undergraduate students. The undergraduate students developed three main systems for the drop tower: a hoist/release mechanism, a deceleration device and the experimental drop rig frame. Figure A-2(a) is a photograph of the deceleration device, which is used to slow down and ultimately stop the experimental test rig after its 1.1-second free fall. Figure A-2(b) is a photograph of the microgravity bio ester fuel droplet ignition delay apparatus. This apparatus has been used to perform ignition delay experiments in normal gravity and microgravity droplet ignition experiments in the 1.1 second drop tower.
