EnglishThe strategies adopted to control the combustion in Diesel applications play a key role when dealing with current and future requirements of the automotive market for Diesel powertrain systems. Direct measurement of the combustion process, e.g. by means of in-cylinder pressure sensor, offers the possibility to achieve the target “quasi” automatically all over the vehicle lifetime in widely different operating conditions. Beside the traditional combustion control in closed loop (i.e. based on inner torque and/or combustion timing), the exploitation of in-cylinder pressure signal offers a variety of possible further applications, e.g. smart detection of Diesel fuel quality variation, control of combustion noise, modeling engine exhaust emission (e.g. NOx). In this contribution we like to address two main topics. A) an overview about the ongoing cylinder pressure based function development activities is given and the respective benefits are illustrated showing some experimental results. B) Additionally we like to present the results of recent developments regarding efficient implementations of some cylinder pressure based features helping to limit the impact of these new functionalities on ECU resources.
