Turbocharging of Small Internal Combustion Engines as a Means of Improving Engine/Application System Fuel Economy.
Abstract
This report presents the results of prototype manufacturing, rig testing, application, and engine testing of a small advanced technology turbocharger. The turbocharger features variable turbine nozzles, ball bearings supported rotor system, self contained lube system and a broad operating range compressor. The purpose of the work was to show the potential benefits of the subject turbocharger in enhancing specific fuel consumption, emissions, and transient response of a diesel engine. The work was accomplished through laboratory testing of hardware and subsequent mathematical duty cycle simulation using the acquired data. The proposed turbocharger was manufactured and successfully run on a turbocharger test rig. Compressor maps were generated for several compressor trims with vaned and vaneless diffusers. A turbocharger was successfully run for 53 hours on a John Deere, 239 cubic inch, four cylinder, diesel engine. Fuel consumption and emissions data were obtained for this engine as well as the 'as received' turbocharged engine and the engine with no turbocharger.
