THE USEFUL LIFE OF ENGINE OIL IS KNOWN TO BE HIGHLY DEPENDENT ON FORMULATION AND THE ENGINE OPERATING MODE. CONSEQUENTLY, AN OIL-CHANGE INTERVAL BASED ON MILES TRAVELED OR ENGINE OPERATING HOURS DOES NOT NECESSARILY DEFINE THE IN-SERVICE QUALITY OF THE OIL. ONE PROBLEM IN PARTICULAR FOR DIESEL ENGINES IS THAT OIL DISPERSANCY CAN FAIL VERY RAPIDLY. THIS ENABLES THE SUSPENDED SOOT PARTICLES TO GEL ...

THE ESCAPE OF HYDROCARBONS FROMA VARIETY OF SOURCES CAN PRESENT A HEALTH SAFETY PROBLEM. THIS PROPOSAL IS FOR RESEARCH FUNDS TO EXPLORE A FLAMELESS IONIZATION CONCEPT TO DETECT SUCH GASES. SMALL QUANTITIES OF HYDROCARBONS (E.G. 0.03% V/V) IN EITHER AIR OR RARE GASES CAN GENERATE LARGE PENNING EFFECTS (ENHANCED IONIZATION THROUGH COLLISIONS WITH METASTABLE METASTABLE STATES). INITIAL EXPLORATORY ST ...

MANY COMBUSTION EXPERIMENTS INVOLVING PARTICLE SIZING AND RADIATION MEASUREMENT REQUIRE AN ACCURATE KNOWLEDGE OF THE REFRACTIVE (N) AND ABSORPTION (K) INDICES OF SOOT. EVEN THOUGH SOOT IS A COMPLEX HYDROCARBON WITH A PARTICULARLY HIGH C:H MASS RATIO, VALUES FOR N AND K FOR CARBON ARE OFTENUSED AS BEING EQUIVALENT FOR SOOT. LITERATURE VALUES OF N AND K FOR SOOT AND CARBON SHOW WIDE SCATTER: 1.40
