Engine Development

A comprehensive mechanical testing program was part of the development of the Diesel engine for the GEVO locomotive family. The test program has been developed under consideration of the demands of a railroad application. The program included both fired engine and component rig testing. Component rig tests were used to validate major components early in the design stage. Engine testing included measurements to validate the CAE models and allow detailed experimental development of components and subsystems. Several endurance runs have proven the reliability of the new engine.

The paper briefly reviews past work on diesel engine noise with particular reference to medium speed engines. A survey carried out on a large number of British and European turbocharged and water-cooled dieseis having bores in the range 2 3/4 in to 33 in (∼ 70 mm to 840 mm) clearly indicated at least two main sources. A qualitative analysis of the problem suggested these to be due to combustion and piston transverse motion in the liner clearance space. None of the engines examined had an International Standards Organization rating lower than Noise Rating 85. A comparison of theoretical trends with those obtained from the survey proved encouraging and application of the analytical findings to five specific engines having bores of 5 in, 8 in, 10 1/4 in, 12 1/2 in and 14 1/4 in (∼ 127 mm, 200 mm, 260 mm, 320 mm and 360 mm) yielded reasonable estimates of the overall noise, but poor approximations to the relevant frequency spectra. Much more work on the effects of crankcase attenuation would appear in order. It is concluded that the wider acceptance of medium speed dieseis will not lead to increased noise problems provided appropriate action is taken at the design stage. Broad design recommendations are presented and the causes of variations of noise with time and of engine to engine scatter discussed. The marked improvements obtained on a 14 1/4 in (∼ 360 mm) bore engine are shown.

This paper summarizes the analytical and experimental investigation of fuel-injection-controllable medium speed diesel engines using kerosene fuels. The investigation focuses on analyzing and testing the effects of using JP-8 kerosene fuel for an engine of this type, on engine fuel injection, in-cylinder combustion, and output performances and exhaust emissions. Main properties of JP-8 fuel compared to those of conventional 2-D diesel in affecting the engine processes are identified and analyzed in connection with the engine processes. The consequent effects are analytically predicted prior to actual engine testing. Results from testing a medium-speed diesel engine using 2-D diesel and JP-8 fuel separately are presented and agree closely in the trends of variation with the analysis and prediction.

Evaluation of combustion characteristic, engine performances and exhaust emissions of nanoparticles blended in palm oil methyl ester (POME) was conducted in this experiment using a single-cylinder diesel engine. Nanoparticles used was aluminium oxide (Al2O3) and silicon dioxide (SiO2) with a portion of 50 ppm and 100 ppm. SiO2 and Al2O3 were blended in POME and labelled as PS50, PS100 and PA50, PA100, respectively. The data results for PS and PA fuel were compared to POME test fuel. Single cylinder diesel engine YANMAR TF120M attached with DEWESoft data acquisition module (DAQ) model SIRIUSi-HS was used in this experiment. Various engine loads of zero, 7 N.m, 14 Nm, 21 N.m and 28 N.m at a constant engine speed of 1800 rpm were applied during engine testing. Results for each fuel were obtained by calculating the average three times repetition of engine testing. Findings show that the highest maximum pressure of nanoparticles fuel increase by 16.3% compared to POME test fuel. Other than that, the engine peak torque and engine power show a significant increase by 43% and 44%, respectively, recorded during the PS50 fuel test. Meanwhile, emissions of nanoparticles fuel show a large decrease by 10% of oxide of nitrogen (NOx), 6.3% reduction of carbon dioxide (CO2) and a slight decrease of 0.02% on carbon monoxide (CO). Addition of nanoparticles in biodiesel show positive improvements when used in diesel engines and further details were discussed.

The 701F is a high-temperature 50 Hz industrial grade 220 MW size engine based on a scaling of the 501F 150 MW class 60 Hz machine, and incorporates a higher compressor pressure ratio to increase the thermal efficiency. The prototype engine is under a two-year performance and reliability verification testing program at MHI’s Yokohama Plant and was initially fired in June of 1992. This paper describes the 701F design features design changes made from 501F. The associated performance and reliability verification test program will also be presented.
