Abstract
Extensive studies in various technological fields have been conducted to determine the most appropriate engine configuration (arrangement and number of cylinders) for Honda's next-generation compact luxury automobiles. One of the basic concepts incorporated into these models include an ‘exhilarating drive’. Studies in the noise/vibration field disclosed that noise/vibration levels must be reduced while simultaneously realizing linearity in noise/vibration increase.
As a result, an in-line five cylinder engine was chosen for this purpose. Additionally, Honda designed a new five-point engine mount system for a longitudinally-mounted engine in its FWD layout.
Crankshaft rumbling noise in the in-line five cylinder engine was proven to be caused by crankshaft torsional resonance, as found in previous research of in-line four and six cylinder engines. This noise deteriorates linearity sensation. An in-line five cylinder engine which allows ‘exhilarating drive’ was successfully developed through the resolution of these problems.
