CASE STUDY: Multi-Spark ignition system for fuel consumption and exhaust emissions reduction in a high performance GDI engine

RCP

The Challenge

Developing a combustion control system based on optimal management of multiple spark discharge events, in order to increase combustion stability, reduce pollutant emissions and fuel consumption, and avoid partial or missing combustion cycles. Our client’s request was a cost-effective solution to several combustion-related issues that affect Gasoline Direct Injection (GDI) engines during cold start and part load operation. The problem of optimizing combustion efficiency and improving its stability during such operating modes is even more critical for high performance engines, which are designed to maximize charge efficiency especially at medium-high engine speeds.

 

The Solution

Using the original ECU to control all the actuation parameters including spark advance, and Miracle to realize the multicharge/discharge coil current pattern. The Rapid Control Prototyping system has been designed to guarantee flexibility, accuracy and easy access: it has been equipped with an easy-to-use interface, enabling the user to change crucial control parameters in real-time, such as the number of subsequent charge-discharge pulses, the dwell time of each coil charging event, and the intervals between consecutive sparks.
