Effect of Pre-Chamber Volume and Nozzle Diameter on Pre-Chamber Ignition in Heavy Duty Natural Gas Engines

SAE Technical Paper Series, 2015
<div class="section abstract"><div class="htmlview paragraph">It has previously been shown by the authors that the pre-chamber ignition technique operating with fuel-rich pre-chamber combustion strategy is a very effective means of extending the lean limit of combustion with excess air in heavy duty natural gas engines in order to improve ...

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.

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 ...

A Numerical Investigation of Pre-chamber Combustion Engines

2020
This work aims to enhance fundamental and practical understanding of pre-chamber (PC) combustion engines, using computational fluid dynamics (CFD) simulations conducted with the software CONVERGE employing the Reynolds-averaged Navier-Stokes turbulence closure and the well-stirred reactor combustion model for methane oxidation.

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.

Modeling Diesel Combustion in a Pre-chamber and Main Chamber

SAE Technical Paper Series, 2004
<div class="htmlview paragraph">Three-dimensional numerical simulations of a diesel-fueled engine with a pre-chamber located in the cylinder head and a bowl in the piston were performed. The study considers the effect of diesel combustion in the pre-chamber on turbulence generation and hence fuel-air mixing and combustion in the piston-bowl ...

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

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
