Abstract
In this work, an innovative piston bowl design that physically divides the combustion chamber into a central zone and a peripheral zone is employed to assist the control of the ethanol-diesel combustion process via heat release shaping. The spatial combustion zone partition divides the premixed ethanol-air mixture into two portions, and the combustion event (timing and extent) of each portion can be controlled by the temporal diesel injection scheduling. As a result, the heat release profile of ethanol-diesel dual-fuel combustion is properly shaped to avoid excessive pressure rise rates and thus to improve the engine performance. The investigation is carried out through theoretical simulation study and empirical engine tests. Parametric simulation is first performed to evaluate the effects of heat release shaping on combustion noise and engine efficiency and to provide boundary conditions for subsequent engine tests. In the engine tests, the engine performance is examined through emission measurements and efficiency analyses, and combustion characteristics are investigated focusing on the correlation between the combustion noise and heat release shaping. As demonstrated by the test results, the heat release profiles representing the combustion events in the central zone and peripheral zone can be actively controlled via diesel injections (fuelling amount and timing), towards the desired heat release shaping. The maximum pressure rise rates are substantially reduced to levels of 5~8 bar/°CA that are in the practical range of modern production diesel engines. The dual-chamber piston bowl along with the injection strategy using an early diesel pilot for the peripheral zone and a near-TDC diesel pilot for the central zone shows a great potential of achieving clean, efficient, and smooth ethanol-diesel combustion.
