THE EFFECT OF RAISING SPECIFIC OUTPUT OF A HIGHLY RATED DI DIESEL TRUCK ENGINE ON ITS PERFORMANCE AND EMISSIONS

A study was undertaken to establish what happens to lorry engine emissions, and to turbocharger and injection pressure requirements, as the specific output is raised. For any given engine package, increasing specific output increases injection pressures while reducing air/fuel ratios. Thus, if the highly rated engine must satisfy the same design constraints, then raising the engine operating torque by only 10% resulted in more than 30% increase in total particulates. The same emission levels may be maintained if increases in specific output are accompanied by changes to engine design so as to maintain the air-fuel mixing parameters, specifically air/fuel ratio and injection pressures, throughout the entire engine operating conditions. For the covering abstract see IRRD 865952.
