Advanced

Demonstrating the Performance and Emission Characteristics of a Variable Compression Ratio, Alvar-Cycle Engine

Erlandsson, Olof LU ; Lundholm, Gunnar LU ; Söderberg, Fredrik LU ; Johansson, Bengt LU and Wong, Victor W. (1998) In SAE Technical Paper Series
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)
