For over 20 years, SEM has been innovating and producing ignition systems for engines powered by alternative fuels such as CNG and LNG. Our products have become a preferred choice for OEMs delivering their engines and trucks to clients with strong demand for reduced emissions solutions.
We offer standard inductive ignition coils, including coil top and different types of extension solutions. As an option, our inductive ignition system can be equipped with our I2CM (ignition and injection Control Module), that can drive up to 6 ignition coils and 8 injectors.
The SEM capacitive ignition system is the state-of-the-art ignition system, that been on the market for decades, offering superior combustion and monitoring diagnostics features, such as pre-ignition and misfire detection, peak-pressure location for reduced fuel consumption and possibility to monitor the spark plug wear for service on-demand applications.
The next generation of capacitive system, with FlexiSpark®, takes the ignition performance to new levels and improves the spark plug wear significantly. FlexiSpark® offers superior control of the power and duration of the spark, which ensures an efficient ignition, thus enabling optimal engine performance at all engine operating conditions.
