Summary:

The concept of the variable stroke engine (VSE) is explained and the problems related to its use are discussed. Single cylinder combustion data are combined with published multi-cylinder VSE friction data to formulate engine model. This engine model is coupled with a vehicle model to make projections of 55/45 fuel economy and NOx g/mile which are compared with similar projections for a throttled engine. At an NOx level of 0.93 g/km (1.5 g/mile), VSE fuel economy improvements ranged from 2 to 20%, depending upon the frictional losses and vehicle power-to-weight ratio used in the models
