Increased environmental awareness in cities across the globe means that vehicles used in public transportation often use engine solutions developed for alternative fuels. As a result, one of SEM’s fastest growing product areas is ignition systems for engines run on biogas and natural gas. We provide customised solutions for commercial vehicles and stationary applications.

Environmental issues have high priority around the world. Technical solutions to minimise environmental impact are making steady progress in most fields.

For many years SEM has delivered ignition systems for natural gas vehicles in the US where authorities early on were setting tough demands for emission levels. We also deliver ignition systems for stationary engines that run on fuels like natural gas and biogas.

The engines are used in applications such as electricity production which is a fast growing market.

Proprietary technology for monitoring and diagnostics enables SEM to meet tough application requirements. With the use of ion current sensing, using only the spark plug as a sensor, we can provide a number of diagnostic tools.
