Engineered Flux for Low Temperature Solders
SMTA International, 2018ABSTRACT Low temperature solders are becoming more common in surface mount assembly. Critical SMT components cannot handle the temperatures used for lead-free soldering which typically reaches 240 – 250 °C. Sensitive critical components might be damaged by these high temperatures.

Engine Lubrication And Fuel Economy At Low Ambient Temperatures
SAE Technical Paper Series, 1988<div class="htmlview paragraph">A low ambient temperature increases wear and fuel consumption in vehicle engines. The startability of the engine and the start-up of lubrication are highly dependent on the type of engine oil (mineral, semisynthetic, synthetic), whereas fuel consumption depends more on the engine type and driving conditions.< ...

Low-Temperature Engine Oil Pumpability in Full-Scale Engines
SAE Technical Paper Series, 1975<div class="htmlview paragraph">ASTM Committee D-2 has undertaken a program to develop a laboratory test which correlates with low-temperature engine oil pumpability in field service. As the first step in this program, pumpability data were obtained using thirteen ASTM Pumpability Reference Oils in seven full-scale engines.

Low Temperature Oxidation, Engine Knock
1999A detailed knowledge of the combustion processes in internal combustion engines is required if one wishes to further improve on the remarkable development of engine technology and related fuel technology. Such improvements aim at the efficient use of fuels with a minimum amount of pollutant emissions. In the specific case of the spark ignited engine, i.

“Understanding Diesel Engine Lubrication at Low Temperature”
SAE Technical Paper Series, 1990<div class="htmlview paragraph">Oil pumpability in passenger car gasoline engines was well-characterized by an ASTM program and by individual researchers in the 1970's and early 1980's. Oil pumpability in diesel engines however, was not investigated to any significant extent until the mid-1980's. This study was initiated to define the performance

Low-Temperature Natural Gas Combustion Engines
2018Advanced or low-temperature combustion engines have shown the potential to achieve high fuel conversion efficiency with minimal emissions formation and therefore can provide solutions for future powertrain systems. Numerous advanced combustion concepts have been explored, including both spark-ignited and compression-ignited concepts, and each one has ...
