Thesis (M. Diploma (Mechanical Engineering))--Cape Technikon, 1992. / Radius hardening on journals of forged steel Diesel engine crankshafts is performed in order to increase fatigue life characteristics. This requirement may be necessary if the demands for engine power are to be increased, but where the existing crankshaft design is close to its fatigue limit, such that an increase in loading will cause it to'fail. Induction hardening of journal radii changes the make-up of the material from a coarse to a fine crystalline structure which alters the features of crack propagation. As a consequence of this higher loads can be applied onto the crankshaft without ultimately resulting in catastrophic material failure. Extending the induction hardened zone from the bearing surfaces into the radii of journals, culminates in process difficulties which are not experienced in non-radius hardened Hardening of journal radii induces crankshafts. as well as releases stresses in the crankshaft webs. This results in a deformation of the crankshaft which can be measured in the form of journal runout. Such a problem cannot be overcome by straightening the crankshafts in order to reduce runout, since this will cause Straightening hand induces the radii to crack once hardened. in the unhardened state on the other stresses which will be released again after hardening. This results in an increase in runout. High runout indicates that stresses have been induced into the crankshaft material. This is undesirable since this will make critical manufacturing processes such as grinding, governing of journal lengths, uncontrollable. It can furthermore result in creep of the crankshaft long after the manufacturing date. This results in crankshaft deformation, noticeable through an increase in runout. Since the crankshaft cannot be straightened after hardening, the consequence is that it will be unusable. The process must therefore be developed in such a manner, that all variables which can contribute towards stress induction resulting in journal 'runout, must be investigated and resolved.

A CAT C6.6 turbocharged diesel engine was operated in dual-fuel diesel-hydrogen mode. Hydrogen was inducted into the intake and replaced a portion of the diesel fuel. Hydrogen was added across multiple engine speeds and loads until reaching the knock limit, identified by a threshold on the rate of in-cylinder pressure rise. In-cylinder pressure and emissions data were recorded and compared to diesel-only operation. Up to 74% H2 substitution for diesel fuel was achieved. Hydrogen addition increased thermal efficiency up to 32.4%, increased peak in-cylinder pressure up to 40.0%, increased the maximum rate of pressure rise up to 281%, advanced injection timing up to 13.6°, increased NOx emissions up to 224%, and reduced CO2 emissions up to 47.6%. CO and HC emissions were not significantly affected during dual-fuel operation. At 25% load an operating condition was observed with low NOx and nearly 0 CO2 emissions, which however exhibited unstable combustion.
