Visualization of Ammonia Engine by Pre-Chamber Igniter

SAE Technical Paper Series
<div class="section abstract"><div class="htmlview paragraph">Ammonia is considered more and more as a promising carbon-free fuel for internal combustion engines to contribute to the decarbonization of several sectors where replacing conventional engines with batteries or fuel cells remains unsuitable. However, ammonia properties can induce

Detailed Approach for Pre-Chamber Heat Release Analysis for the HSASI Pre-Chamber Spark Plug Using a Pressure Sensor Glow Plug

SAE Technical Paper Series
<div class="section abstract"><div class="htmlview paragraph">The hot surface-assisted spark ignition (HSASI) pre-chamber spark plug, which was developed at the Karlsruhe University of Applied Sciences, increases the dilution limit with excess air and the tolerance to residual gas in the pre-chamber compared to a conventional passive pre ...

Influence of alternative pre-chamber fuels on engine performance

International Journal of Engine Research
The application of active pre-chamber (PC) combustion systems offers potential increases of the indicated efficiency of spark-ignition (SI) engines by increasing the lean operating limit. In conventional SI operation, methanol revealed promising engine performance without substantial knock limitation. In PC operation with methanol under lean conditions,
