Emission Reduction Strategies for Small Single Cylinder Diesel Engine Using Valve Timing and Swirl Ratio

Small diesel engines are widely used for commercial vehicle and passenger car applications due to their higher torque requirements, fuel economy, and better thermal efficiency. These engines are exposed to different operating and environmental conditions and hence emissions from these engines are erratic. Strategies are required to enhance performance and reduce engine-out emissions considering...

A Transient Hydrostatic Dynamometer for Single Cylinder Engine Research

A new high-bandwidth transient dynamometer has been designed and is being built for application to a single-cylinder research engine. The goal of this system is to accurately reproduce all of the dynamic, instantaneous torques that this single-cylinder would experience if it were in a multi-cylinder engine. This is accomplished by calculating these instantaneous torques in real time using a det...

Correlation of the Witmer Formboard and Cylinder Test

In the spring of 1915, the cylinder test was given by two advanced graduate students in psychology to 47 men and 28 women undergraduates in Psychology 2c at the University of Pennsylvania. The following fall, this same test as well as the Witmer formboard was given by advanced students in psychology to 55 men and 59 women undergraduates in Psychology lc. These tests were employed to give the st...

Vacuum Diagnosis with an RGA

Stanford Research Systems phone: (408)744-9040 www.thinkSRS.com Residual Gas Analyzer (RGA) is the term used for a class of quadrupole mass spectrometers that typically cover mass ranges from 1 to 100 or 200 amu (atomic mass units), and are intended to be used for the analysis of the gasses present in high and ultra-high vacuum. The RGA’s resolution is sufficient to clearly distinguish peaks th...
