A comprehensive investigation of the performance of a 6-cylinder turbocharged engine was undertaken under steady state and transient conditions.Friction was measured under steady state conditions and a formula for calculating fmep is proposed. It was found that friction under transient conditions is higher than would be predicted from quasi-steady considerations. A combustion model was applied to the engine during steady state and transient conditions. It was found that combustion deteriorated under transient conditions even after including turbocharger lag effects.
