Study on the Optimal Pre-Chamber Geometry for Active Pre-Chamber Gas Engines

SAE Technical Paper Series
<div class="section abstract"><div class="htmlview paragraph">In a pre-chamber engine, fuel in the main-chamber is ignited and combusted by the combustion gas injected from the pre-chamber. Therefore, further fuel dilution is possible and thermal efficiency can be also improved.

Pre-Chamber Stratified Charge Engine Combustion Studies

SAE Technical Paper Series, 1974
<div class="htmlview paragraph">Single-cylinder experiments were conducted with a 3-valve carbureted pre-chamber stratified charge engine in comparison with a conventional engine. The pre-chamber engine operation is governed by many design and operating variables. This investigation was limited to determining the effect of overall air/fuel ratio,

Temperature Calculation Methodology of Pre Chamber With Homogeneous Charge

SAE Technical Paper Series, 2020
<div class="section abstract"><div class="htmlview paragraph">The methodology for temperature calculations of homogeneous prechamber must be analyzed from a one-dimensional analytical model so that it is possible to determine the temperature profiles during the filling and emptying of the gases, so that it can avoid abnormalities such as ...

Investigations on Pre-Chamber Spark Plug with Pilot Injection

SAE Technical Paper Series, 2007
<div class="htmlview paragraph">Combustion concepts for future SI engines try to meet CO₂ emission commitments and legislation all over the world. Where the diesel engine has an advantage by principle, the efficiency of the SI engine has to be improved significantly, while of course there must be no deterioration in exhaust

Simultaneous Direct-Photography of Flame Propagation Inside Pre-Chamber and Main-Chamber in Gasoline Engine with Passive Pre-Chamber

SAE International Journal of Advances and Current Practices in Mobility
<div class="section abstract"><div class="htmlview paragraph">Pre-chamber combustion is well known for the effective way to improve thermal efficiency in internal combustion engine. An active pre-chamber can accomplish super lean burn while a passive pre-chamber can easily improve combustion with low-cost.

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,
