Demonstrating the Performance and Emission Characteristics of a Variable Compression Ratio, Alvar-Cycle Engine
(1998)- Abstract
- This paper is a direct continuation of a previous study
that addressed the performance and design of a variable
compression engine, the Alvar-Cycle Engine [1]. The
earlier study was presented at the SAE International
Conference and Exposition in Detroit during February 23-
26, 1998 as SAE paper 981027. In the present paper test
results from a single cylinder prototype are reviewed and
compared with a similar conventional engine. Efficiency
and emissions are shown as function of speed, load, and
compression ratio. The influence of residual gas on knock
characteristics is shown. The potential for high power
density through heavy supercharging... (More) - This paper is a direct continuation of a previous study
